この発明は一般家庭等から排出される廃棄物を埋立処分
するための構造物、および廃棄物処分方法に関する。DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a structure for disposing of waste discharged from general households in a landfill, and a waste disposal method.
近年各家庭から排出される一般廃棄物は増加の一途をた
どり、各地方自治体に大きな負担となっている。これは
処理費の増加もさることながら、従来のような自治体が
所有している土地にそのまま埋立てするものでは、地域
住民から環境問題の発生が生じ、現状では管理型処分場
の建設に推移している。In recent years, the amount of general waste generated by households has been increasing steadily, placing a heavy burden on local governments. This is not only due to an increase in processing costs, but the traditional method of landfilling directly on land owned by local governments causes environmental problems for local residents, and the current trend is to construct managed disposal sites. are doing.
管理型処分場の多くは、山間地の斜面を整形し、地表面
にゴムシートを張った上に、廃棄物を滞積埋立し、同時
に地下水と浸出液を分離しながら排水処理を行っている
。Most controlled disposal sites involve shaping slopes in mountainous areas, placing rubber sheets on the ground surface, and then dumping the waste into a pile, while treating wastewater while separating groundwater and leachate.
一方、人口が密集している都市周辺の埋立地、平地に建

行い、その底部および法面にゴムシートを張った上に、
廃棄物を埋立処分し、同時に地下水と浸出液を分離しな
がら排水処理を行っている。On the other hand, in managed disposal sites built on reclaimed land or flat land near densely populated cities, the groundwater level is high, and after constructing impermeable walls with thin steel sheet piles up to the impermeable layer, internal excavation is necessary. After that, a rubber sheet was placed on the bottom and the slope, and
Waste is disposed of in a landfill, and at the same time, wastewater is treated while separating groundwater and leachate.
しかし、これらの管理型の処分場でも下記のような問題
点があった。However, even these managed disposal sites have the following problems.
■ 容量の割に広い面積(浅底・広口)が必要となり、
用地の少ない都市近郊には不向きである。■ A large area (shallow bottom, wide mouth) is required for the capacity,
It is not suitable for areas near cities where land is scarce.
■ 大気開放型のため、臭気等周辺の環境問題が発生し
、住民等の多い都市近郊には不向きである。■ Because it is open to the atmosphere, it causes environmental problems such as odor, making it unsuitable for areas near urban areas where there are many residents.
■ −旦ゴムシートに欠陥を生じると処分場としての機
能が損なわれる為埋立に伴うシートの維持管理に難点が
ある。■ - If a rubber sheet develops a defect, its function as a disposal site will be impaired, making it difficult to maintain and manage the sheet during landfilling.
この発明は上記事情に鑑みなされたものである。その目

構造物および廃棄物処分方法を提案するにある。This invention was made in view of the above circumstances. The purpose is to dispose of a large amount of waste compared to the land area, to eliminate the risk of deteriorating the environment in terms of sewage, odor, or landscape, to save time and effort in maintenance, and to dispose of waste in landfills. The purpose of the present invention is to propose a waste disposal structure and a waste disposal method that can be effectively used as a structure after disposal.

する。The waste disposal structure of the present invention is characterized by having an underground cylindrical waste landfill space surrounded by an underground continuous wall that reaches an impermeable layer and provided with a wood shield at the bottom. do. Another waste disposal structure is claimed in claim 1.
The structure for waste disposal according to the present invention is characterized in that two parts of the structure for waste disposal as described in paragraph 1 are provided with a roof covering the upper surface. Another method for disposing of waste is to construct an underground cylindrical space that reaches the impermeable layer around it, dump the waste into this space, and remove the top surface of the space after filling it with a landfill. It is characterized by providing a covering floor body.

The interior is excavated while being reinforced with reinforced concrete rings 10 at predetermined height intervals, and the earth is lifted up using a vessel or the like (Figure 3). Note that the ring 10 may be unnecessary depending on conditions such as the size of the structure, ground conditions, and structure of the underground continuous wall. When the excavation reaches the specified depth, the first

Depending on the situation, it may be enough to cover a simple waterproof sheet. Although the structure in the above embodiment has a cylindrical shape, it may have a rectangular cylindrical shape.
〔作 用〕
この発明は以上の構成からなり、廃棄物処分用構造物は
、■大深度の地中空間を利用するために、地表の占有面
積が少ない割りに、大容量の埋立て能力が確保できる。[Function] This invention has the above-mentioned configuration, and the waste disposal structure has a large-capacity landfill capacity despite the small surface area it occupies in order to utilize the deep underground space. Can be secured.
■不透水層に辻する地中連続壁で囲まれ、底部に遮水玉
を設けであるので、地中空間と地下水との遮断が確実に

雨水が廃棄物に浸入せず、浸出液量が増大しないので、
浸出液の処理等の保守管理に手間がかからず経費が安価
となる。■Since it is surrounded by a continuous underground wall that connects to the impermeable layer, and a water-blocking ball is installed at the bottom, the underground space is reliably isolated from the groundwater, preventing the environment from being contaminated by leachate from the waste. Never. ■Since waste is buried in a cylindrical space underground, compared to conventional disposal sites, odors do not spread, the scenery is not spoiled, and the surrounding environment is not affected. It is more suitable to cover the top surface and provide a roof as in the example, and if the top surface is covered, rainwater will not enter the waste and the amount of leachate will not increase.
Maintenance management such as treatment of leachate does not require much effort and costs are low.

効利用ができる。Furthermore, in the waste disposal method according to the present invention, waste is dumped into an underground cylindrical space and a floor is provided to cover the top of the space after filling it in a landfill, so that the waste inside is isolated from the outside. ,
Since only a small amount of gas is emitted, it can be safely disposed of in a landfill without harming the environment. Moreover, the structure after the floor body is installed can be effectively used as a sports facility, etc. by simple modification.
この発明は以上の通りであり、占有面積に比べ埋立能力

減を図ることができる。This invention is as described above, and has a large landfill capacity compared to the area it occupies, and there is no risk of damaging the surrounding environment even if it is constructed in a large city. Maintenance management is not labor-intensive and costs are low, and structures after waste disposal can be used effectively, reducing disposal costs.
