〔産業上の利用分野〕
この発明は一般家庭等から排出される廃棄物等の廃棄物
処分場に関する。DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a waste disposal site for wastes etc. discharged from general households.
従来、一般に広く採用されている廃棄物処分場は、浅型

物の投棄に追随し覆工していく必要があり、処分場の全
容量を有効に利用できない等の問題点があった。Conventionally, the waste disposal sites that have been widely used have been shallow disposal sites. This shallow disposal site has a maximum depth of about 6 to 10 meters, and requires a large area for the amount to be disposed of.
Construction is difficult in urban areas where land prices are high. In addition, rubber sheets are laid over the entire surface to prevent leachate from dispersing from the dumped waste, but damage to the sheets can easily lead to environmental pollution such as outflow of sewage and contamination with groundwater. In addition, the odor spreads, and in order to prevent this spread, it is necessary to line the disposal site as waste is dumped, which poses problems such as not being able to effectively utilize the full capacity of the disposal site.

コストとなる。Recently, underground continuous wall 2 reaching impermeable layer 1 as shown in Figure 5
A deep disposal site has been proposed that has an underground cylindrical space for waste dumping surrounded by a water barrier with a seepage barrier 3 at the bottom. Deep disposal sites have a large disposal volume compared to the land area, and there is no risk of environmental deterioration due to sewage or odors. However, since the surrounding underground water pressure is acting on the underground continuous wall, the continuous wall 2
It is difficult to excavate deeply to near the lower end, and it is necessary to provide strength to withstand large earth pressure by attaching a reinforcing ring 4, etc., and it is also necessary to provide wood shielding, resulting in high cost.
従って深型処分場は用地費が高い都市部ではよいが、他
の地域では必ずしもメリットのあるものではなかった。Therefore, while deep disposal sites are good in urban areas where land costs are high, they are not necessarily advantageous in other areas.
この発明は上記問題点で着目しなされたものである。そ
の目的は、用地面積に比べ大きな廃棄物処分容積を得る
ことができ、建設コストが安価であり、かつ、汚水や臭
気による環境汚染の恐れがない廃棄物処分場を提案する
にある。This invention was made in view of the above-mentioned problems. The purpose is to propose a waste disposal site that has a large waste disposal volume compared to the land area, is inexpensive to construct, and is free from the risk of environmental pollution due to sewage and odors.

付けである。[Means and Examples for Solving the Problems] Figure 1 shows a waste disposal site according to the present invention, in which underground cylindrical waste is surrounded by an underground continuous wall 2 that reaches an impermeable layer 1. It has a dumping space 5. This sky M5 is filled with water 6, and its water level 7 is slightly lower than the underground water level 8 outside the underground continuous wall 2. Additionally, a spherical roof 9 covering the upper surface of the space 5 is attached.

外側の地下水位８より僅かに低い水位に維持される。This disposal site dumps waste 10 into a space 5 filled with water 6. As the water level 7 rises as the waste 10 is dumped, the water in the space is pumped up using an attached pump (not shown).
The water level is maintained slightly lower than the groundwater level 8 outside.
この廃棄物処分場は第２．３．４図に示す工程順で構築

の上部に屋根９を取付は処分場が構築される（第４図）
。This waste disposal site will be constructed in the order of steps shown in Figure 2.3.4. First, a continuous underground wall 2 is built that reaches the impermeable layer 1 (Figure 2), and excavated while keeping the water level 7 inside the wall the same as the water level 8 outside (Figure 3). A waste dumping space 5 filled with water 6 is formed by excavating near the impermeable layer 1, and a roof 9 is attached above it to construct a disposal site (Figure 4).
.
この廃棄物処分場は以上の構成からなり、廃棄物投棄空
間は水を湛え、その水位は外側の地下水位より僅かに低
くなしである。■従って投棄空間の水圧が外側の水圧よ
り低く、空間内の汚水が外側に流出しない。連続壁に作
用する使用中の力が小さく、また、施工中の内外地下水
位が同じであり大きな力が作用しないので■安価に連続
壁を構築でき、■底部遮水工が不要であり、■連続壁の
最下端付近まで掘削し、投棄空間とすることができる。This waste disposal site has the above-mentioned configuration, and the waste dumping space is filled with water, and the water level is slightly lower than the groundwater level outside. ■Therefore, the water pressure in the dumping space is lower than the water pressure outside, and the sewage inside the space does not flow out. The force that acts on the continuous wall during use is small, and the groundwater levels inside and outside are the same during construction, so no large force is applied.■ Continuous walls can be constructed at low cost.■ No water-blocking work at the bottom is required. It is possible to excavate to the bottom of the continuous wall and create a dumping space.
なお、実施例のごとく屋根を取付けると臭気の拡散が防
止でき好適である。Incidentally, it is preferable to attach a roof as in the embodiment because it can prevent the diffusion of odors.
この発明になる廃棄物処分場は用地面積に比べ、容積が
大で、かつ建設費が安価であり、廃棄物単位容積量当り
、処分場コストが安く、従来の深型処分場のＡ程度とな
る。また、汚水臭気等による環境悪化を防止できる。The waste disposal site of this invention has a large capacity compared to the land area, and is inexpensive to construct.The disposal site cost per unit volume of waste is low, and is comparable to that of conventional deep disposal sites. Become. Furthermore, environmental deterioration due to sewage odor and the like can be prevented.
