Description

Storage or infiltration tank

本発明は、地下に埋設する貯留槽もしくは浸透槽の技術に属する。 The present invention belongs to the technology of a storage tank or an infiltration tank buried underground.

雨水の流出抑制を目的として、プラスチックなどで製造されたテーブル状、容器状あるいはパイプ状部材などの単位部材を地下に配設し、貯留空間を確保して雨水を一時的に貯留する貯留浸透施設が普及している。この目的のために各種の形状の部材が例えば特開昭62-101097、特開昭62-126179、特開平 9-296486、特開平11-43971、特開平10-115778などに提案かつ使用されている。いずれの方法も部材を配設しその周囲を透水性もしくは遮水性のシート類で包み、その内部空間に雨水を貯蔵する貯留浸透施設とするものである。
雨水の流出抑制を目的とするためには、地下水位が低い場合は透水性のシートで包み、貯留された雨水を徐々に地下に浸透させ、地下水位が高い場合は地下水が内部に入らないように遮水性のシートで包み雨水を貯留した後、徐々に下水あるいは河川に放流することが行われている。 A storage and penetration facility that temporarily stores rainwater by securing storage space by placing unit members such as tables, containers, or pipes made of plastic, etc., in the basement for the purpose of preventing rainwater outflow Is popular. For this purpose, various shaped members have been proposed and used in, for example, Japanese Patent Laid-Open Nos. 62-101097, 62-126179, 9-296486, 11-43971, 10-115778, etc. Yes. Each method is a storage and penetration facility in which members are disposed and the periphery thereof is wrapped with water-permeable or water-proof sheets to store rainwater in the internal space.
In order to control the outflow of rainwater, wrap it with a permeable sheet when the groundwater level is low, and gradually infiltrate the stored rainwater into the basement so that the groundwater does not enter inside when the groundwater level is high. After wrapping with a water-impervious sheet and storing rainwater, it is gradually discharged into sewage or rivers.

図５に示すこれら単位部材であるテーブル状部材を用いた場合の貯留空間の形成においては、テーブル状部材を、適宜継ぎ手を用いて配設する方法が用いられている。接続箇所に応じた各種の継ぎ手が用いられ、施工時の手間を要するものであった。 In the formation of the storage space in the case of using the table-like member as these unit members shown in FIG. 5, a method of arranging the table-like member using a joint as appropriate is used. Various types of joints were used according to the connection location, which required labor during construction.
