Description

  The present invention relates to a filler used for a storage and penetration tank for rainwater and the like, and to a storage and penetration tank for rainwater and the like whose upper surface forms a ceiling portion by a covering means. The present invention relates to a storage and permeation tank filler such as rainwater that can easily remove deposits and maintenance, and a storage and permeation tank such as rainwater using the filler.

  Conventionally, a storage and permeation tank for rainwater or the like has been constructed using a basement such as a parking lot, a park, a house, or a factory site. These rainwater storage and infiltration tanks are constructed as a water storage space facility to prevent inundation of houses and flooding of rivers in urban areas, or as countermeasures for water shortages. After that, it will be discharged into rivers, etc., or actively penetrated underground to prevent disasters caused by flooding of rivers and flooding of houses. Furthermore, the storage and permeation tank for rainwater and the like is used for pumping and using the stored rainwater and the like.

  Such a storage and permeation tank for rainwater or the like forms a water storage space by being filled with a filler. That is, the filling material is arranged vertically and horizontally inside the water tank formed by digging the ground, and is stacked and filled up and down to form a water storage gap.

Storage and penetration tanks for rainwater, etc. formed by filling with fillers accumulate mud, sand, garbage, etc. that flowed in when used for a long period of time, not only soiling the tank but also reducing the storage space, rainwater, etc. This will reduce the storage efficiency. Therefore, in order to remove these deposits, a groove for discharging the deposits is formed on the bottom surface of the water storage tank, and a water spray pipe having a large number of water injection holes between the support columns of the filler is arranged in the horizontal direction. A device has been proposed.
