Description

本発明は、大口径の下水道管路や雨水管路等、泥や固形物を含む水が流れる管路の構造と、その管路内に搬入した内面部材を用いて管路内壁を補修する管路の補修構造に関し、更に詳しくは、底部が平面状の馬蹄形管や矩形管等に適した管路の構造および管路の補修構造に関する。   The present invention relates to a pipe structure for repairing an inner wall of a pipe using a structure of a pipe through which water containing mud or solid matter flows, such as a large-diameter sewer pipe or a rainwater pipe, and an inner surface member carried into the pipe. More particularly, the present invention relates to a pipe structure and a pipe repair structure suitable for a horseshoe tube or a rectangular tube having a flat bottom.

老朽化した下水道管路等の既設管路の補修方法として、管路の内面を内面部材(内張り材)で全面的に覆う方法が知られている(例えば特許文献1〜特許文献2等を参照。)。   As a method for repairing an existing pipeline such as an aged sewer pipeline, a method of covering the entire inner surface of the pipeline with an inner surface member (lining material) is known (see, for example, Patent Literature 1 to Patent Literature 2). .)

また、このような補修方法として、特に管路内に人が入って作業可能な大口径管の補修に関し、本出願人らは、補修時に支保工を必要とせず、施行の簡素化および工期の短縮等を実現できる管路の補修方法(特許文献3)や、強度の期待できない、劣化の進んだ管路や異形管路を充分に補強することのできる補修方法並びにその方法により得られる管路の補修構造(特許文献4)について提案している。   In addition, as such a repair method, particularly regarding repair of large-diameter pipes that allow humans to enter and work in the pipeline, the present applicants do not need support work at the time of repair, simplify the implementation and work schedule Pipeline repair method (Patent Document 3) that can realize shortening, repair method that can sufficiently reinforce deteriorated pipes and deformed pipes that cannot be expected in strength, and pipes obtained by the method The repair structure (Patent Document 4) is proposed.

以上のような管路の補修方法は、内面部材を管路の筒長方向に連続したものとすることにより、管路の筒長方向に継ぎ目部がなく、管内物の流下能力を向上させることができるという利点があるものの、管路の補修長が長くなるに従い、内面部材の総長も増大するため、輸送上または製造設備上において困難なケースが生じてきた。   The pipe repair method as described above improves the flowability of the piped material by having the inner surface member continuous in the pipe length direction of the pipe, so that there is no joint in the pipe length direction of the pipe. However, since the total length of the inner surface member increases as the repair length of the pipe increases, a difficult case has arisen in transportation or manufacturing equipment.

また、骨組み状補強体を用いた管路の補修構造においては、硬化性充填材の注入時に、管路の底部近傍で、内面部材と管路壁面との間に管内の滞留水や空気が噛み込んでしまい、硬化性充填材の未充填部位が形成されてしまう場合があった。特に、馬蹄形管や矩形管(ボックスカルバート)等、底部が平面状の管路は、その底部近傍における内面部材と管路壁面との間に滞留水や空気の噛み込みが多く、未充填部位が形成されてしまう恐れが高い。   Further, in the pipe repair structure using the frame-shaped reinforcing body, when the curable filler is injected, the staying water or air in the pipe is caught between the inner surface member and the pipe wall surface near the bottom of the pipe. In some cases, an unfilled portion of the curable filler is formed. In particular, pipes with a flat bottom, such as horseshoe-shaped pipes and rectangular pipes (box culverts), have a lot of stagnant water or air between the inner surface member and the wall of the pipe near the bottom. There is a high risk of being formed.

そこで、本出願人らは、管路筒長方向に一定の長さの定尺内面部材を、その長手方向および幅方向に当接して配設し、これらを管路内で一体化することにより、輸送上または製造設備上の問題を解決するとともに、施工現場での取り扱いおよび作業性の良い管路の補修構造に関する提案を行なっている(特許文献5)。   Therefore, the present applicants arrange a fixed-length inner member having a fixed length in the pipe tube length direction in contact with the longitudinal direction and the width direction, and integrate them in the pipe line. In addition to solving problems in transportation or manufacturing equipment, a proposal has been made regarding a pipe repair structure that is easy to handle and work at a construction site (Patent Document 5).

また、管路の壁面とこれを覆う内面部材との間の空隙内に設置される補強体の内縁に、硬化性充填材を管路筒長方向に通過させる切り込みを設け、硬化性充填材の管路筒長方向の流動をスムーズにして、硬化性充填材の未充填部位の発生を防止する管路の補修構造を提案している(特許文献6)。   In addition, the inner edge of the reinforcing body installed in the gap between the wall surface of the pipe line and the inner surface member covering it is provided with a notch that allows the curable filler to pass in the pipe tube length direction. A repair structure of a pipe line that smoothes the flow in the pipe tube length direction and prevents the occurrence of unfilled portions of the curable filler is proposed (Patent Document 6).

図11から図14は、これらの提案に係る従来の管路の補修構造の概略を説明する図である。この管路の補修方法は、高剛性材料(例えば鋼等)からなる中空骨組み状の補強体を管路内において組み立て、この補強体の内側に樹脂あるいは金属等からなる内面部材(内張り材)を取り付けた後、これら内面部材と管路壁面とで形成される空間に硬化性充填材(裏込め材)を充填するものである。   FIG. 11 to FIG. 14 are diagrams for explaining the outline of a conventional pipe repair structure according to these proposals. In this pipe repair method, a hollow frame-shaped reinforcing body made of a highly rigid material (for example, steel) is assembled in the pipe, and an inner surface member (lining material) made of resin, metal, or the like is placed inside the reinforcing body. After the attachment, the space formed by the inner surface member and the pipe wall surface is filled with a curable filler (backfill material).

例えば、例のような断面が円形の既設管路の場合、図11のように、先ず既設管路1の内部に、管路内壁1aに略沿った形状の補強部材2を組み立てる。この補強部材2は、マンホール等から搬入した複数の分割補強部材(この例においては、3個の分割補強部材2a,2b,2c)を相互に結合して、全体として管路内壁1aに略沿ったリング状に組み立てられる。この補強部材2の管路内側には、後述する嵌合部材11と定尺内面部材30を嵌め込むための複数の嵌合用凹部(嵌合部2p)が、周方向に所定のピッチで形成されているとともに、その外縁には周方向に一様に連続する凹凸が形成されている。   For example, in the case of an existing pipe line having a circular cross section as in the example, first, the reinforcing member 2 having a shape substantially along the pipe inner wall 1a is assembled inside the existing pipe line 1 as shown in FIG. The reinforcing member 2 is composed of a plurality of divided reinforcing members (in this example, three divided reinforcing members 2a, 2b, 2c) carried in from a manhole or the like, and substantially along the pipe inner wall 1a as a whole. Assembled in a ring shape. A plurality of fitting recesses (fitting portions 2p) for fitting a fitting member 11 and a regular inner surface member 30 to be described later are formed at a predetermined pitch in the circumferential direction inside the pipe line of the reinforcing member 2. In addition, unevenness that is continuously continuous in the circumferential direction is formed on the outer edge.

なお、このリング状の補強部材2は、筒長方向に貫通する貫通穴2qがそれぞれ周方向に一定の間隔で形成されており、複数のリング状補強部材2が形成された段階で、パイプ材とボルトおよびナット等からなる連結部材(図示省略)によって、これらのリング状補強部材2を既設管路の筒長方向に一定の間隔で連結・一体化し、全体として中空骨組み状の補強体とされる。また、補強部材2の径方向内縁には、各貫通穴2qに連通する切り込み2rが形成されており、定尺内面部材30が取り付けられた場合でも、この内面部材30に接する補強部材2の内縁近傍に、既設管路筒長方向に連通するすきまが形成されるよになっている。   In addition, the ring-shaped reinforcing member 2 has pipe holes 2q penetrating in the cylinder length direction at regular intervals in the circumferential direction, and at the stage when the plurality of ring-shaped reinforcing members 2 are formed, These ring-shaped reinforcing members 2 are connected and integrated at a constant interval in the tube length direction of the existing pipe line by connecting members (not shown) made of bolts, nuts, and the like to form a hollow frame-shaped reinforcing body as a whole. The In addition, a notch 2r communicating with each through hole 2q is formed on the radially inner edge of the reinforcing member 2, and even when the fixed inner member 30 is attached, the inner edge of the reinforcing member 2 in contact with the inner member 30 A clearance communicating with the existing pipe tube length direction is formed in the vicinity.

次に、補強部材2の嵌合部2pのそれぞれに、嵌合部材11を既設管路1の筒長方向に沿って互いに平行に取り付け、これら各嵌合部材11を介して、定尺内面部材30を取り付ける。この定尺内面部材30は、図12に示すように、一定の長さ、例えば5m程度の長さを有する左右対称の一様断面の帯状体であり、平板状の本体部分両縁部に片面側に突出する嵌合用凸部30a,30bが一体形成された形状を有している。この嵌合用凸部30a,30b間の距離は、補強部材2の内側に形成された嵌合部2pどうしの距離(ピッチ)と等しく、互いに隣接する内面部材30の一方の嵌合用凸部30aと他方の内面部材30の嵌合用凸部30bとが突き合わされた状態で、それぞれ嵌合部材11の開口部に挿入される。なお、これら嵌合用凸部30a,30bと嵌合部材11との間には、防水のためのシール部材12が介在配置される場合もある。   Next, the fitting member 11 is attached to each of the fitting portions 2p of the reinforcing member 2 in parallel with each other along the tube length direction of the existing pipe line 1, and the fixed-length inner surface member is interposed via each of the fitting members 11. 30 is attached. As shown in FIG. 12, the regular inner surface member 30 is a belt-like body having a uniform length, for example, about 5 m, and a symmetric uniform cross section. The protrusions 30a and 30b for fitting projecting to the side have a shape integrally formed. The distance between the fitting convex portions 30a and 30b is equal to the distance (pitch) between the fitting portions 2p formed on the inner side of the reinforcing member 2, and one of the fitting convex portions 30a of the inner surface member 30 adjacent to each other. Each of the other inner surface members 30 is inserted into the opening of the fitting member 11 in a state where the fitting convex portion 30b is abutted with each other. In some cases, a sealing member 12 for waterproofing is interposed between the fitting convex portions 30 a and 30 b and the fitting member 11.

その後、図13および図14に示すように、この定尺内面部材30と管路内壁1aとの間の空隙に硬化性充填材3が注入される。この注入された硬化性充填材3は、リング状の補強部材2ごとに筒長方向に区切られた空隙の区画を、既設管路の底部側から充填しながら、補強部材2の外縁の凹凸によって形成されたすきま、あるいは前記切り込み2rによって補強部材2の内縁近傍に形成されたすきま等から、次の空隙区画へと順次流れ込んで行くこととなる。   Thereafter, as shown in FIG. 13 and FIG. 14, the curable filler 3 is injected into the gap between the fixed inner member 30 and the pipe inner wall 1a. The injected curable filler 3 fills the space defined by the ring-shaped reinforcing member 2 in the cylinder length direction from the bottom side of the existing pipe line, by the unevenness of the outer edge of the reinforcing member 2. From the formed clearance or the clearance formed in the vicinity of the inner edge of the reinforcing member 2 by the notch 2r, the fluid sequentially flows into the next gap section.

ところで、下水道管路や雨水管路等の底部には、沈砂と呼ばれる固形汚物が堆積することが知られており、従来からの要望として、これら泥や固形物を含む水を流下させる管路には、できるだけ沈砂が溜まらない構造であること、およびこの沈砂を掃除(除去)し易い構造であること、が求められている。   By the way, it is known that solid filth called sedimentation deposits on the bottom of sewer pipes and rainwater pipes, and as a conventional request, pipes that allow water containing mud and solids to flow down are used. Therefore, there is a demand for a structure in which sedimentation does not accumulate as much as possible, and a structure in which the sedimentation can be easily cleaned (removed).

しかしながら、馬蹄形管や矩形管(ボックスカルバート)等、底部が平面状の管路は、管内物の流下速度が低く、固形物が堆積し易い傾向にあり、断面が円形の管路に比べ、沈砂が多く生じてしまう場合があった。   However, pipes with a flat bottom, such as horseshoe-shaped pipes and rectangular pipes (box culverts), have a lower flow rate of the material in the pipes and tend to accumulate solids. There was a case where many occurred.

本発明は、このような実情に鑑みてなされたものであり、管路底部に固形物が堆積し難く、また堆積した場合でも除去が容易な管路と管路の補修構造を提供することを目的としている。   The present invention has been made in view of such circumstances, and provides a pipeline and a pipeline repair structure in which solid matter is difficult to deposit on the bottom of the pipeline and can be easily removed even when deposited. It is aimed.

前記の目的を達成するために、請求項1に記載の発明は、内壁に沿って配設された内面部材により、固形物を含む水を流下させる管路内面が形成された管路であって、前記管路内面のうち、少なくともその底部に、管路筒長方向の溝またはリブが複数形成されていることによって特徴づけられる。   In order to achieve the above-mentioned object, the invention according to claim 1 is a pipeline in which an inner surface of a pipeline that allows water containing solids to flow down is formed by an inner surface member disposed along an inner wall. In addition, a plurality of grooves or ribs in the tube tube length direction are formed at least on the bottom of the inner surface of the tube.

本発明は、管路の底部表面に、水の流れに倣った凹凸形状(リブレット:Riblet)を形成することによって、この流水に対する抵抗を低減し、所期の目的を達成しようとするものである。   The present invention is intended to reduce the resistance to flowing water and achieve the intended purpose by forming an uneven shape (riblet) following the flow of water on the bottom surface of the pipe. .

すなわち、大口径の下水道管路や雨水管路等、泥や固形物を含む水が流れる管路の底部に、管路筒長方向の複数の溝またはリブからなるリブレットを形成することにより、管内物に対する摩擦抵抗が低減される。従って、本発明の管路は、管路底部に固形物が堆積し難く、また堆積した場合でも除去が容易な管路とすることが可能となる。   That is, by forming a riblet consisting of a plurality of grooves or ribs in the pipe tube length direction at the bottom of a pipe through which water containing mud and solids flows, such as a large-diameter sewer pipe or rainwater pipe, The frictional resistance against is reduced. Therefore, the pipe line of the present invention can be a pipe line in which solid matter hardly accumulates at the bottom of the pipe line and can be easily removed even when it is deposited.

また、請求項2に記載の発明は、管路の内壁に略沿って配設された補強部材の内側に、管路筒長方向に連続する内面部材を取り付けるとともに、この内面部材と管路の内壁との間に、硬化性充填材を充填する管路の補修構造において、前記内面部材のうち、少なくとも管路の底部に位置する内面部材の管路内側表面には、管路筒長方向に連続する凹部または凸部が形成されていることを特徴とする。   According to the second aspect of the present invention, an inner surface member continuous in the tube tube length direction is attached to the inner side of the reinforcing member disposed substantially along the inner wall of the conduit, and the inner surface member and the conduit are connected to each other. In the pipe repair structure filled with a curable filler between the inner wall and the inner wall, at least on the inner surface of the inner pipe located at the bottom of the pipe, the inner surface of the pipe is in the pipe tube length direction. A continuous concave portion or convex portion is formed.

この構成によって、内面部材を用いた既設管路の補修構造においても、請求項1に記載の発明と同様のリブレット効果を奏することができる。従って、管路の補修後も、管内物のスムーズな流れが維持されるとともに、管路底部に固形物が堆積し難く、また堆積した場合でも除去が容易な管路とすることができる。なお、ここで述べた「内面部材」とは、管路筒長方向に直線状に配置される長尺の内面部材を包含する。   With this configuration, the riblet effect similar to that of the invention according to claim 1 can be obtained even in the repair structure of the existing pipe line using the inner surface member. Therefore, even after the pipe is repaired, a smooth flow of the inside of the pipe is maintained, and solids are difficult to deposit on the bottom of the pipe, and even when deposited, the pipe can be easily removed. The “inner surface member” described here includes a long inner member arranged linearly in the tube tube length direction.

ここで、所定の幅で管路筒長方向に一定の長さの定尺内面部材を、その長手方向および幅方向に連結して用いる管路の補修構造においては、前記定尺内面部材の管路内側表面を、その幅方向に凹状または凸状に形成すれば良い(請求項3)。   Here, in a pipe repair structure in which a fixed-length inner member having a predetermined width and a fixed length is connected in the longitudinal direction and the width direction, the pipe of the fixed-length inner member is used. The inner surface of the road may be formed in a concave shape or a convex shape in the width direction (Claim 3).

この発明は、管路筒長方向(すなわち水の流れ方向)に並べられた内面部材のピッチ幅を、リブレット形状のリピート幅として利用するものである。すなわち、所定のピッチ幅の定尺内面部材を用いた補修方法の場合は、管路底部に配置された定尺内面部材の個々の表面を、その幅方向に凹状または凸状とすることにより、前述と同様のリブレット効果を奏することができる。   In the present invention, the pitch width of the inner surface members arranged in the pipe tube length direction (that is, the water flow direction) is used as the repeat width of the riblet shape. That is, in the case of a repair method using a regular inner member with a predetermined pitch width, by making the individual surfaces of the regular inner member disposed at the bottom of the pipe line concave or convex in the width direction, The riblet effect similar to the above can be exhibited.

なお、前記定尺内面部材における管路内側表面の凹形状の最大深さまたは凸形状の最大高さは、幅方向両端の角部の頂点どうしを結んだ仮想基準面に対し、0.5〜5.0mmであることが望ましい(請求項4)。   In addition, the maximum depth of the concave shape or the maximum height of the convex shape on the inner surface of the pipe line in the fixed inner surface member is 0.5 to the virtual reference plane that connects the vertices of the corners at both ends in the width direction. It is desirable that it be 5.0 mm (claim 4).

リブレットは、その凹凸形状の間の高さの差がある程度必要とされるが、下水道管路や雨水管路等の場合は、堆積した沈砂を掃除(除去)し易い構造であることが求められるため、その高さの差は5mm以下に抑えることが好ましい。   The riblet needs to have a certain height difference between its concave and convex shapes, but in the case of sewer pipes, rainwater pipes, etc., it is required to have a structure that is easy to clean (remove) the accumulated sand. The height difference is preferably suppressed to 5 mm or less.

また、所定のピッチ幅の定尺内面部材を用いた補修方法の場合、定尺内面部材の個々の表面をその幅方向に凹状または凸状とする代わりに、前記定尺内面部材の管路内側表面における幅方向両端の角部をR形状に形成する(請求項5)か、あるいは、前記定尺内面部材の管路内側表面における幅方向両端の角部に面取り加工を施す構成(請求項6)としても良い。これらの構成によっても、請求項4と同様のリブレット効果を奏することができる。   Further, in the case of a repair method using a fixed-length inner member having a predetermined pitch width, instead of making each surface of the fixed-surface inner member concave or convex in the width direction, the inside of the pipe of the fixed-length inner member The corners at both ends in the width direction on the surface are formed in an R shape (Claim 5), or the corner parts at both ends in the width direction on the inner surface of the pipe of the fixed inner surface member are chamfered (Claim 6). ). Also with these configurations, the same riblet effect as that of the fourth aspect can be achieved.

一方、請求項7に記載の発明は、内面部材の取り付け作業の低減および硬化性充填材における未充填部位の発生の防止を目的としたものであり、補強体の管路内側に、前記嵌合部のピッチの幅で管路筒長方向に一定の長さの定尺内面部材が、その長手方向および幅方向に当接して配設され、これら定尺内面部材と管路の内壁との間に、硬化性充填材が充填されてなる管路の補修構造において、前記定尺内面部材が、前記嵌合部のピッチの2倍の幅に形成されているとともに、この2倍幅の定尺内面部材の幅方向中央に、管路外側に向かって突出して前記嵌合部に係合する係合部が形成されていることを特徴とする。   On the other hand, the invention described in claim 7 aims to reduce the mounting work of the inner surface member and to prevent the occurrence of unfilled portions in the curable filler, and the fitting is performed inside the pipe line of the reinforcing body. A fixed-length inner member having a constant length in the pipe tube length direction with a pitch width of the section is disposed in contact with the longitudinal direction and the width direction, and between the fixed inner member and the inner wall of the pipe line Further, in the pipe repair structure filled with the curable filler, the fixed inner surface member is formed to have a width twice as large as the pitch of the fitting portion, and the double width fixed length An engaging portion that protrudes toward the outer side of the duct and engages with the fitting portion is formed at the center in the width direction of the inner surface member.

この構成により、内面部材施工時の作業工数を削減することができる。また、この2倍幅の定尺内面部材の幅方向中央に設けられた係合部によって、硬化性充填剤の注入時にも、注入圧による内面部材の浮き上がりが防止されるとともに、この係合部と補強体の嵌合部と間に形成されるすきまにより、従来の補強体の内縁に形成されていた切り込み等を設けなくても、硬化性充填材の管路筒長方向の流動がスムーズになる。従って、本発明の管路の補修構造は、内面部材と管路壁面の間の滞留水や空気の噛み込みが少なく、管路底部における硬化性充填材の未充填部位の発生を防止することができる。   With this configuration, it is possible to reduce the number of work steps when constructing the inner surface member. In addition, the engagement portion provided in the center in the width direction of the double-width inner surface member prevents the inner surface member from being lifted by the injection pressure even when the curable filler is injected. With the gap formed between the fitting part and the reinforcing member, the flow of the curable filler in the length direction of the pipe tube can be smoothly performed without the need to provide a cut or the like formed on the inner edge of the conventional reinforcing member. Become. Therefore, the pipe repair structure of the present invention has less stagnant water or air between the inner surface member and the pipe wall surface, and can prevent the occurrence of an unfilled portion of the curable filler at the pipe bottom. it can.

なお、この構成の場合も、前記2倍幅の定尺内面部材の管路内側表面を、該内面部材の幅方向中央を挟んでそれぞれ幅方向に凹状または凸状に形成する(請求項8)ことにより、前述のリブレット効果を奏することができる。   Also in this configuration, the inner surface of the pipe of the double-width inner surface member is formed in a concave shape or a convex shape in the width direction across the center in the width direction of the inner surface member (Claim 8). As a result, the aforementioned riblet effect can be achieved.

また、請求項4に記載の発明と同様、前記2倍幅の定尺内面部材における管路内側表面の凹形状の最大深さまたは凸形状の最大高さは、この管路内側表面の幅方向中央と幅方向両端の角部の頂点とを結んだ仮想基準面に対し、それぞれ0.5〜5.0mmであることが望ましい(請求項9)。   Similarly to the invention according to claim 4, the maximum depth of the concave shape or the maximum height of the convex shape on the inner surface of the pipe in the double-width inner surface member is the width direction of the inner surface of the pipe. It is desirable that the distance is 0.5 to 5.0 mm with respect to the virtual reference plane connecting the center and the apexes of the corners at both ends in the width direction (claim 9).

また更に、2倍幅の定尺内面部材の個々の表面を凹状または凸状とする代わりに、前記2倍幅の定尺内面部材の管路内側表面における幅方向両端の角部をR形状に形成する(請求項10)か、あるいは、前記2倍幅の定尺内面部材の管路内側表面における幅方向両端の角部に面取り加工を施す構成(請求項11)としても良い。   Further, instead of making the individual surfaces of the double-width standard inner member concave or convex, the corners at both ends in the width direction on the inner surface of the pipe of the double-width standard inner member are formed in an R shape. It may be formed (Claim 10), or may be configured to chamfer the corners at both ends in the width direction on the pipe inner surface of the double-width fixed inner surface member (Claim 11).

以上のように、管路の底部表面に、水の流れに倣ったリブレット形状を形成することによって、固形物が堆積し難く、また堆積した場合でも除去が容易な管路とすることができる。   As described above, by forming a riblet shape that follows the flow of water on the bottom surface of the pipe, it is difficult to deposit solid matter, and it is possible to obtain a pipe that is easy to remove even if it is deposited.

また、本発明の管路の補修構造によれば、管路の補修後も、管内物のスムーズな流れが維持されるとともに、管路底部に固形物が堆積し難く、また堆積した場合でも除去が容易となる。特に、馬蹄形管や矩形管(ボックスカルバート)等、底部が平面状で管内物の流下速度が低い管路においても、その流下能力を向上させることが可能となる。   In addition, according to the pipe repair structure of the present invention, a smooth flow of the inside of the pipe is maintained even after the pipe is repaired, and solid matter hardly accumulates at the bottom of the pipe, and even if it accumulates, it is removed. Becomes easy. In particular, even in a pipe line such as a horseshoe tube or a rectangular tube (box culvert) where the bottom is flat and the flow speed of the pipe is low, the flow capacity can be improved.

また、管路の内壁に沿うように組み立てられた中空骨組み状の補強体の管路内側に、前記嵌合部のピッチの幅で管路筒長方向に一定の長さの定尺内面部材を、その長手方向および幅方向に当接して配設し、これら定尺内面部材と管路の内壁との間に、硬化性充填材を充填する管路の補修構造においては、前記補強体の嵌合部のピッチの2倍の幅の定尺内面部材を用いることにより、内面部材施工時の作業工数を削減することができるとともに、管路底部における硬化性充填材の未充填部位の発生を防止することができる。   Further, on the inner side of the pipe of the hollow frame-shaped reinforcing body assembled along the inner wall of the pipe, a constant-length inner member having a fixed length in the pipe tube length direction with the pitch width of the fitting portion. In the pipe repair structure in which the curable filler is filled between the fixed inner surface member and the inner wall of the pipe, the reinforcing body is fitted in the longitudinal direction and the width direction. By using a fixed inner member with a width twice the pitch of the joint, it is possible to reduce the number of work steps when constructing the inner member and to prevent the occurrence of unfilled portions of curable filler at the bottom of the pipe can do.

以下、図面を参照しつつこの発明を実施するための形態について説明する。
図1は、本発明の第1実施形態における管路の補修構造を示す管路径方向の断面図であり、図2は図1のA部拡大模式図である。また、図3は、この第1実施形態における定尺内面部材10の断面形状の例を示す図である。なお、従来例と同様の機能を有する構成部材には、同じ符号を付記して詳細な説明を省略する。
Hereinafter, embodiments for carrying out the present invention will be described with reference to the drawings.
FIG. 1 is a cross-sectional view in the pipe radial direction showing a pipe repair structure according to the first embodiment of the present invention, and FIG. 2 is an enlarged schematic view of part A of FIG. Moreover, FIG. 3 is a figure which shows the example of the cross-sectional shape of the fixed-length inner surface member 10 in this 1st Embodiment. In addition, the same code | symbol is attached | subjected to the structural member which has a function similar to a prior art example, and detailed description is abbreviate | omitted.

この第1実施形態における管路の補修方法も、先ず、高剛性材料(例えば鋼等)からなり、管路内側に所定のピッチで嵌合部2pが設けられた分割補強部材を、管路内壁1aに沿うように組み立て、管路1の断面形状に略沿った補強部材2を形成する。そして、この補強部材2を管路1の筒長方向に複数個配置するとともに、これら補強部材2を連結部材(図示省略)により相互に一体化して、中空骨組み状の補強体を構築する。   The pipe repair method according to the first embodiment also includes a split reinforcement member made of a highly rigid material (for example, steel) and provided with fitting portions 2p at a predetermined pitch inside the pipe. Assembling along 1a, the reinforcing member 2 substantially along the cross-sectional shape of the pipe line 1 is formed. A plurality of the reinforcing members 2 are arranged in the tube length direction of the pipe line 1 and these reinforcing members 2 are integrated with each other by a connecting member (not shown) to construct a hollow frame-shaped reinforcing body.

次に、補強部材2の嵌合部2pのそれぞれに、嵌合部材11を既設管路1の筒長方向に沿って互いに平行に取り付け、隣接する内面部材10の一方の嵌合用凸部10aと他方の内面部材10の嵌合用凸部10bとを突き合わされた状態で、シール部材12を介してそれぞれ嵌合部材11の開口部に挿入する。その後、この定尺内面部材10と管路内壁1aとの間の空隙に硬化性充填材3が注入される。   Next, the fitting member 11 is attached to each of the fitting portions 2p of the reinforcing member 2 in parallel with each other along the tube length direction of the existing pipe line 1, and one fitting convex portion 10a of the adjacent inner surface member 10 and The fitting member 10 is inserted into the opening of the fitting member 11 via the seal member 12 in a state where the fitting convex portion 10 b of the other inner surface member 10 is abutted. Thereafter, the curable filler 3 is injected into the gap between the fixed inner member 10 and the pipe inner wall 1a.

本実施形態における管路の補修構造が従来の補修構造と異なる点は、図3に示すように、定尺内面部材10の管路内側表面10cが、その幅方向に凹状に形成されている点である。また、この定尺内面部材10は、幅方向両端の角部10d,10dの頂点どうしを結んだ仮想基準面Pに対し、前記凹形状の最大深さHmaxが2mmとなるように形成されている。   The pipe repair structure in the present embodiment is different from the conventional repair structure in that the pipe inner surface 10c of the fixed inner member 10 is formed in a concave shape in the width direction as shown in FIG. It is. Further, the regular inner member 10 is formed such that the maximum depth Hmax of the concave shape is 2 mm with respect to a virtual reference plane P connecting the vertices of the corners 10d, 10d at both ends in the width direction. .

この構成によって、本実施形態における管路の内面には、水の流れに倣った凹凸形状(リブレット:Riblet)が形成される。従って、本実施形態における管路は補修後も、管内物のスムーズな流れが維持されるとともに、管路底部に固形物が堆積し難く、また堆積した場合でも除去が容易な管路とすることができる。   With this configuration, an uneven shape (riblet) following the flow of water is formed on the inner surface of the conduit in the present embodiment. Therefore, the pipeline in the present embodiment should be a pipeline that can maintain a smooth flow of the inside of the pipe even after repair, and that it is difficult for solids to accumulate on the bottom of the pipe and that can be easily removed even if it accumulates. Can do.

また特に、この例のような馬蹄形管や矩形管(ボックスカルバート)等、底部が平面状の管路は、管内物の流下速度が低く沈砂が堆積し易い傾向にあるが、この実施形態のように、管路内面にリブレット構造を形成することによって、管内物の流下能力を向上させることが可能になる。   In particular, a pipe with a flat bottom, such as a horseshoe tube or a rectangular tube (box culvert) as in this example, has a low flow speed of the pipe and tends to accumulate sand. In addition, by forming a riblet structure on the inner surface of the pipe line, it is possible to improve the flow-through ability of the inside of the pipe.

なお、このリブレット構造は、図4のように、定尺内面部材10の管路内側表面10cにおける幅方向両端の角部10dをR形状に形成するか、あるいは、図5のように、幅方向両端の角部10dに面取り加工を施して構成しても良い。また、これらの形状と前記凹形状を組み合わせて構成しても、同様の効果を奏することができる。   In this riblet structure, corners 10d at both ends in the width direction on the pipe inner surface 10c of the fixed inner member 10 are formed in an R shape as shown in FIG. 4, or in the width direction as shown in FIG. You may comprise by chamfering to the corner | angular part 10d of both ends. Moreover, even if it comprises combining these shapes and the said concave shape, there can exist the same effect.

次に、本発明の第2実施形態について説明する。
図6は、本発明の第2実施形態における管路の補修構造を示す管路径方向の断面図であり、図7は図6のB部拡大模式図である。また、図8は、この第2実施形態における定尺内面部材20の断面形状の例を示す図である。
Next, a second embodiment of the present invention will be described.
FIG. 6 is a cross-sectional view in the pipe radial direction showing the pipe repair structure according to the second embodiment of the present invention, and FIG. 7 is an enlarged schematic view of part B of FIG. Moreover, FIG. 8 is a figure which shows the example of the cross-sectional shape of the fixed-length inner surface member 20 in this 2nd Embodiment.

本実施形態における管路の補修方法も、第1実施形態と同様、管路内側に所定のピッチで嵌合部2pが設けられた補強部材2を用いて、管路1の断面形状に略沿った中空骨組み状の補強体を構築し、この補強体の内側に樹脂製の定尺内面部材20を取り付けた後、これら内面部材20と管路内壁1aとで形成される空間に硬化性充填材3を充填するものである。   As in the first embodiment, the pipe repair method according to the present embodiment also substantially follows the cross-sectional shape of the pipe 1 using the reinforcing member 2 provided with the fitting portions 2p at a predetermined pitch inside the pipe. After constructing a hollow frame-shaped reinforcing body and attaching a resin-made inner surface member 20 inside the reinforcing body, a curable filler is formed in a space formed by the inner surface member 20 and the pipe inner wall 1a. 3 is filled.

本実施形態における管路の補修構造の特徴は、図7のように、定尺内面部材20が、補強部材2の嵌合部2aのピッチの2倍の幅に形成されているとともに、この定尺内面部材20の幅方向中央に、管路外側に向かって突出して前記嵌合部2aに係合する係合部20cが形成されている点である。   The feature of the pipe repair structure in this embodiment is that, as shown in FIG. 7, the fixed inner member 20 is formed to have a width twice as large as the pitch of the fitting portions 2 a of the reinforcing member 2. An engagement portion 20c that protrudes toward the outside of the pipe line and engages with the fitting portion 2a is formed at the center in the width direction of the inner surface member 20.

また、この2倍幅の定尺内面部材20の管路内側表面20dは、その幅方向中央20eを挟んでそれぞれ幅方向に凹状に形成されているとともに、管路内側表面20dの幅方向中央20eと幅方向両端の角部20f,20fの頂点とを結んだ仮想基準面Pに対し、この凹形状の最大深さHmaxがそれぞれ2mmとなるように形成されている。   Further, the pipe inner surface 20d of the double-width fixed inner member 20 is formed in a concave shape in the width direction across the width direction center 20e, and the width direction center 20e of the pipe inner surface 20d. Are formed so that the maximum depth Hmax of the concave shape is 2 mm with respect to the virtual reference plane P connecting the corners 20f, 20f at both ends in the width direction.

なお、第1実施形態と同様、2倍幅の定尺内面部材20の管路内側表面20dを凹状とする代わりに、この管路内側表面20dにおける幅方向両端の角部20f,20fをR形状に形成する(図9)か、あるいは、管路内側表面20dにおける幅方向両端の角部20f、20fに面取り加工を施しても良い(図10)。また、係合部20cが形成されている幅方向中央20eの管路内側表面20d側に、長手方向に連続する溝やリブ等を形成しても良く、更には、これら端部20fおよび幅方向中央20eの形状と、前記の凹形状を組み合わせて構成しても良い。   As in the first embodiment, instead of making the pipe inner surface 20d of the double-width inner surface member 20 concave, the corners 20f and 20f at both ends in the width direction on the pipe inner surface 20d are R-shaped. The corners 20f and 20f at both ends in the width direction on the pipe inner surface 20d may be chamfered (FIG. 10). In addition, grooves or ribs that are continuous in the longitudinal direction may be formed on the pipe inner surface 20d side of the center 20e in the width direction where the engaging portion 20c is formed, and furthermore, the end 20f and the width direction may be formed. You may comprise combining the shape of the center 20e, and the said concave shape.

この構成によって、硬化性充填剤3の注入時にも、注入圧による内面部材20の浮き上がりが防止されるとともに、この係合部20cと補強部材2の嵌合部2pと間に形成されるすきまにより、硬化性充填材3の管路筒長方向の流動がスムーズになる。従って、本実施形態における管路の補修構造は、内面部材20と管路内壁1aの間の滞留水や空気の噛み込みが少なく、馬蹄形管や矩形管(ボックスカルバート)等、底部が平面状の管路においても、管路底部における硬化性充填材3の未充填部位の発生を防止することができる。   With this configuration, even when the curable filler 3 is injected, the inner surface member 20 is prevented from being lifted by the injection pressure, and the gap formed between the engaging portion 20c and the fitting portion 2p of the reinforcing member 2 is prevented. The flow of the curable filler 3 in the pipe tube length direction becomes smooth. Therefore, the pipe repair structure according to the present embodiment has less stagnant water or air between the inner surface member 20 and the pipe inner wall 1a, and has a flat bottom such as a horseshoe tube or a rectangular tube (box culvert). Even in the pipeline, it is possible to prevent the occurrence of an unfilled portion of the curable filler 3 at the bottom of the pipeline.

また、この補修方法により形成された管路内面は、定尺内面部材20の管路内側表面20dに形成された凹部によって、前記第1実施形態と同様のリブレット効果を奏することができる。従って、本実施形態における管路の補修構造も、管路底部に固形物が堆積し難く、また堆積した場合でも除去が容易な管路とすることができるとともに、底部が平面状の管路における管内物の流下能力を向上させることが可能になる。   Further, the inner surface of the pipe line formed by this repairing method can exhibit the same riblet effect as that of the first embodiment due to the recess formed on the inner pipe surface 20d of the fixed inner surface member 20. Therefore, the pipe repair structure according to the present embodiment also makes it difficult for solids to deposit on the bottom of the pipe and can be easily removed even when deposited, and the bottom is a flat pipe. It becomes possible to improve the flow capacity of the pipe.

更に、以上の管路の補修構造では、施工現場で取り付ける定尺内面部材20を、従来品の2倍の幅としたことで、この取付作業の手間を低減することができる。また、硬化性充填材3の充填がスムーズに行なわれることから、従来の補強部材の内縁に形成されていた切り込み(図11における符号2r)を設ける必要がない。また更に、この切り欠きを設けないことによって、切り欠きによる強度低下を考慮する必要がなく、補強部材2の管路径方向の幅および管路筒長方向の厚みを、従来のものより幅狭および肉薄に設計することができるとともに、その形状加工が容易となる。従って、本実施形態における管路の補修構造は、これらの効果により、従来に比してそのコストを低減することができる。   Further, in the above pipe line repair structure, the fixed inner member 20 to be attached at the construction site has a width twice that of the conventional product, so that the labor of the attachment work can be reduced. Moreover, since the filling of the curable filler 3 is performed smoothly, it is not necessary to provide the cut (reference numeral 2r in FIG. 11) formed in the inner edge of the conventional reinforcing member. Furthermore, by not providing this notch, it is not necessary to consider the strength reduction due to the notch, and the width of the reinforcing member 2 in the pipe radial direction and the thickness in the pipe tube length direction are narrower than those of the conventional one. It can be designed to be thin and its shape processing is easy. Therefore, the repair structure of the pipe line in this embodiment can reduce the cost compared with the past by these effects.

なお、以上の2つの実施形態では、樹脂製の定尺内面部材を用いた管路の補修構造を例に挙げたが、本発明における内面部材は、特に樹脂製に限定されるものではなく、金属等、硬質で耐水性を有する材料で形成すれば良く、その形状も管路筒長方向に連続するもの(長尺内面部材等)であっても良い。   In the above two embodiments, the repair structure of the pipe line using the resin-made fixed-length inner surface member is taken as an example, but the inner surface member in the present invention is not particularly limited to resin, What is necessary is just to form with the material which has hard and water resistance, such as a metal, The thing (long internal member etc.) which the shape continues in a pipe tube length direction may be sufficient.

更にまた、本発明は、種々の断面形状の管路に適用でき得ることは勿論、補修された既設管路以外にも、内面部材を用いて管路内面を施工する新設管路にも適用することができる。   Furthermore, the present invention can be applied to pipes having various cross-sectional shapes, and is also applicable to newly installed pipes in which pipe inner surfaces are constructed using inner surface members in addition to existing repaired pipe lines. be able to.
