Description
Technical field
The invention belongs to optical cable technology field, particularly relate to a kind of optical cable be applied to bottom storm sewer.
Background technology
In recent years, rapidly, Government and enterprise is to the demand of data service in growth at full speed, and data service becomes the focus of each operator contention, actively marches field of data service one after another, makes urban network pore resource day by day nervous for urban network and Access Network development.
Along with the management of urban municipal construction is becoming better and approaching perfection day by day, excavate pipeline and lay examination and approval procedures increasingly strict.Utilize and not yet obtain abundant development and utilization, the storm sewer network of all cities, nearly cover city service area lays optical cable, becomes one of effective way solving existing conduit resource scarcity.
Prior art is laid optical cable and is mainly adopted overhead type to construct in storm sewer, uses a harness fastener that optical cable is fixed on pipeline top, construct loaded down with trivial details, cost is higher, the easy fouling of optical cable not easy care, and storm sewer diameter is less, adds construction limitation.
Summary of the invention
The object of the present invention is to provide a kind of optical cable be applied to bottom storm sewer, to solve the above problems.
In an embodiment of the present invention, provide a kind of optical cable be applied to bottom storm sewer, comprising: stay pipe, be close to that stay pipe outer wall is compact is provided with many roots optical cable; Oversheath is arranged with outside sub-optical cable; Hollow out freeing port is formed between oversheath and sub-optical cable.
Further, be close to oversheath inwall and be also provided with steel band, steel band is the stainless steel compound belt of two sides overlay film;
Further, sub-optical cable comprises optical fiber, fine cream, Loose tube, cable cream, aluminium strip and inner sheath from inside to outside;
Further, aluminium strip is aluminium-plastic tape;
Further, stay pipe inwall and oversheath outer wall all scribble lubricating layer;
Further, lubricating layer is nano coating;
Further, stay pipe adopts polypropylene random copolymer material to make;
Further, oversheath is white polyethylene sheath.
Compared with prior art the invention has the beneficial effects as follows: the present invention only need be put in bottom storm sewer, without the need to the fastening gold utensil of a complete set of stainless steel of constructing on storm sewer top, easy construction, improves operating efficiency, reduces construction cost.
Accompanying drawing explanation
Fig. 1 is a kind of schematic cross-section being applied to optical cable bottom storm sewer of the present invention;
Number in the figure:
1, optical fiber; 2, fine cream; 3, Loose tube; 4, cable cream; 5, aluminium strip; 6, inner sheath; 7, steel band; 8, oversheath; 9, stay pipe; 10, freeing port; 11, lubricating layer.
Embodiment
Also by reference to the accompanying drawings the present invention is described in further detail below by specific embodiment.
Shown in ginseng Fig. 1, Fig. 1 shows a kind of schematic cross-section being applied to optical cable bottom storm sewer of the present invention.
In the present embodiment, a kind of schematic cross-section being applied to optical cable bottom storm sewer, comprising: stay pipe 9, is close to that stay pipe 9 outer wall is compact is provided with many roots optical cable, is arranged with oversheath 8 outside sub-optical cable; Hollow out freeing port 10 is formed between oversheath 8 and sub-optical cable.
Sub-optical cable comprises optical fiber 1, fine cream 2, Loose tube 3, cable cream 4, aluminium strip 5 and inner sheath 6 from inside to outside.Optical fiber 1 is general single mode fiber; Fine cream 2 is the good ointment filling material of water absorptivity; Loose tube 3 is benzene dicarboxylic acid butanediol ester material; Cable cream 4 is water suction ointment; Aluminium strip 5 is anti-moisture and moisture assembly, can select aluminium-plastic tape, for providing ground floor to protect to optical fiber 1; Inner sheath 6 is vinyon layer.
Be close to oversheath inwall and be also provided with the steel band 7 that longitudinal grin indulges bag; steel band 7 is the stainless steel compound belt of two sides overlay film, provides the second layer to protect, and aluminium strip 5 and steel band 7 pairs of optical fiber 1 form the protection of two-layer compound band; make optical fiber 1 not be subject to the invasion of moisture and moisture, guarantee the stability that line signal transmits.
Optical cable center adopts hollow stay pipe 9, improves the anti-pressure ability of optical cable, reduces cable cross-section hydraulic pressure; The preferential polypropylene random copolymer material of stay pipe 9, stay pipe 9 stable performance after making, compression resistance is strong, not easily permeates.
Stay pipe 9 inwall and oversheath 8 outer wall all scribble lubricating layer 11, and lubricating layer 11 smooth surface, can reduce resistance to water-flow, less scaling, are beneficial to rainwater and silt passes through.The nano material that lubricating layer 11 is preferentially novel.
Oversheath 8 adopts white polyethylene sheath, is convenient to distinguish, can be antitheft, also facilitates later maintenance.
Do not increase filling material between each sub-optical cable and oversheath, adopt the hollow out designing and arranging mouth of a river 10, be convenient to rainwater silt and pass through;
The present invention takes full advantage of the storm sewer of all cities, nearly cover city service area, and without the need to again excavating, constructability lays, optical cable is sunken to bottom storm sewer, not easily washes away, and substitutes the fastening gold utensil of a complete set of stainless steel of top construction, reduce construction cost, improve operating efficiency.
A series of detailed description listed is above only illustrating for feasibility embodiment of the present invention; they are also not used to limit the scope of the invention, all do not depart from the skill of the present invention equivalent implementations done of spirit or change all should be included within protection scope of the present invention.
To those skilled in the art, obviously the invention is not restricted to the details of above-mentioned one exemplary embodiment, and when not deviating from spirit of the present invention or essential characteristic, the present invention can be realized in other specific forms.Therefore, no matter from which point, all should embodiment be regarded as exemplary, and be nonrestrictive, scope of the present invention is limited by claims instead of above-mentioned explanation, and all changes be therefore intended in the implication of the equivalency by dropping on claim and scope are included in the present invention.Any Reference numeral in claim should be considered as the claim involved by limiting.
In addition, be to be understood that, although this instructions is described according to embodiment, but not each embodiment only comprises an independently technical scheme, this narrating mode of instructions is only for clarity sake, those skilled in the art should by instructions integrally, and the technical scheme in each embodiment also through appropriately combined, can form other embodiments that it will be appreciated by those skilled in the art that.
