FILTER STRUCTURE FOR RAINWATER PERMEATING BASIN, AND RAINWATER PERMEATING BASIN AND RAINWATER PERMEATING STRUCTURE PROVIDED WITH THE FILTER STRUCTURE
PROBLEM TO BE SOLVED: To provide a filter structure that can enlarge the filter area, along with a rainwater permeating basin that allows the height position of the filter structure on a permeating pipe to be adjusted and can reduce the amount of rainwater pooled at the bottom of the rainwater basin, and a rainwater permeating structure that can remove harmful substances in the rainwater.SOLUTION: A filter structure has a lower frame body of a hat shape of which an outer diameter equals an outer diameter of a collar part of an upper frame body, while a width of a collar part of the lower frame body is larger than a width of the collar part of the upper frame body, and furthermore an intermediate frame body is inserted into the upper and lower frame bodies, or a filter storage unit is installed on the upper frame body. A rainwater passage part is formed on a side wall part of the frame bodies other than the lower frame body. A rainwater permeating basin and a rainwater permeating structure has zeolite filled in a permeating pipe.
【課題】フィルターの面積を大きくすることができるフィルター構造体、また浸透筒上のフィルター構造体の高さ位置を調整することができ、さらには雨水桝の底部に滞留する雨水量を少なくできる雨水浸透桝および雨水中の有害物質を除去できる雨水浸透構造体を提供する。【解決手段】フィルター構造体については、ハット形状の下部枠体の外径を上部枠体のつば部の外径と等しくするとともに、下部枠体のつば部の幅を上部枠体のつば部の幅よりも大きくし、さらには中間部枠体を上下の枠体に挿入し、あるいはフィルター収納体ユニットを上部枠体の上に配置する。また、下部枠体以外の枠体の側壁部に雨水通過部を形成する。雨水浸透桝および雨水浸透構造体については、浸透筒にゼオライトを充填する。【選択図】図２
