The project proposed the construction of a cylindrical underground wall reaching the water-impermeable layer in the ground, excavating the inside of the ground, setting up a bottom made of seepage control at the bottom, and covering the waste with a roof. This disposal site can dispose a large amount of waste in a small site area, does not require rainwater, does not require a water treatment facility, and has excellent operational effects such as no outflow of odor. However, there were also points that required the following improvements.
【０００３】２０万ｍ3 を越えるような大容量の処分場
では、コストの高い地中連続壁が厚くなり、全体の工事
費が高くなる。[0003] In the 200,000 disposal site of large capacity, such as more than m 3, costly underground continuous wall becomes thicker, the whole of the construction costs is higher.
【０００４】地中連続壁は完全な止水構造ではないの
で、にじむ程度の地下水が処分場内に流入してくること
が避けられない。[0004] Since the underground continuous wall does not have a completely waterproof structure, it is unavoidable that the underground groundwater flows into the disposal site.
【０００５】大量の掘削土の処理が必要となり、その処
分に費用が掛かる。[0005] A large amount of excavated soil must be treated and its disposal is expensive.
【０００６】基本的には処分場内の水位を外周部の水位
より低く保ち、外部への汚水の流失がない構造とする
が、外周部の水位が低い場所や外周部の水位変動が激し
い場所に建設した場合には、知らないうちに汚水が外部
に流出する可能性がある。[0006] Basically, the water level in the disposal site is kept lower than the water level in the outer peripheral part so that the wastewater does not flow out to the outside. However, in a place where the water level in the outer peripheral part is low or the water level in the outer peripheral part fluctuates sharply. If constructed, sewage could spill outside without your knowledge.

Without the underground diaphragm wall,
Another object of the present invention is to propose a deep waste disposal site that can be constructed at a relatively low cost with a light burden on excavated soil disposal and that can provide a large-capacity disposal space in a small site area.

【作用および発明の効果】この深型廃棄物処分場は以上
の構成からなり、次の作用効果を奏する。[Operation and Advantages of the Invention] This deep waste disposal site has the above-mentioned configuration and has the following operation and effects.
【００１２】地中連続壁を仮設構造物として扱うことが
できるので大容量の処分場であっても、コストの高い地
中連続壁が薄くてすみ、工事費を低減できる。Since the underground continuous wall can be treated as a temporary structure, the high-cost underground continuous wall can be thinned even in a large-capacity disposal site, and the construction cost can be reduced.
【００１３】地中連続壁を透過した地下水は流下間隙を
流下し集水空間に集められ、外部に排出されるので、廃
棄物を溜める処分空間内に周囲地盤の地下水が流入する
ことがない。The groundwater that has passed through the underground continuous wall flows down the downflow gap, is collected in the water collecting space, and is discharged to the outside, so that the groundwater of the surrounding ground does not flow into the waste disposal space.
【００１４】廃棄物は鉄筋コンクリ−ト製の側壁内の処
分空間に溜められるので、汚水などの液体の外部への流
出は考えられないが、万一、側壁、底盤から流出した場
合でも、流下間隙を流下して集水空間に集められ排出さ
れるため、汚水などによる周辺地盤の汚染はおこらな
い。また、排水管よりの排水を定期的に分析することに
より、側壁、底盤の止水機能の確認ができる。Since the waste is stored in the disposal space in the side wall made of reinforced concrete, it is unlikely that liquid such as sewage will flow out of the container. Since the water flows down the gap and is collected in the catchment space and discharged, the surrounding ground is not contaminated by sewage or the like. In addition, by regularly analyzing the drainage from the drainage pipe, it is possible to confirm the water stopping function of the side wall and the bottom plate.
【００１５】現地盤から上に盛土をすることが可能であ
り、掘削土の全部または大部分を盛土材として使うこと
ができるので、残土が発生し難く工事費を節減できる。Since the embankment can be filled up from the site and the whole or most of the excavated soil can be used as the embankment material, the remaining soil is hardly generated and the construction cost can be reduced.
【００１６】側壁は地中連続壁を支持構造として逆巻き
工法（上から順に側壁コンクリ−トを打設）で構築でき
るため、地中連続壁の壁厚を薄くできるとともに、壁厚
を土圧、水圧が大きくなる下方程大きくでき、コストメ
リットが大きい。Since the side wall can be constructed by the reverse winding method (placing the side wall concrete in order from the top) using the underground continuous wall as a support structure, the wall thickness of the underground continuous wall can be reduced, and the wall thickness can be reduced by earth pressure. The lower the water pressure becomes, the larger the water pressure becomes, and the cost merit is great.
【００１７】以上のように、この深型廃棄物処分場は、
周囲の環境を損なうことがなく、狭い敷地面積に大きな
処分空間をつくることができ、しかも比較的低コストで
構築できる。As described above, this deep waste disposal site
A large disposal space can be created in a small site area without damaging the surrounding environment, and it can be constructed at relatively low cost.
