STORAGE INFILTRATION FACILITY

摘要

PROBLEM TO BE SOLVED: To provide a structure of a novel rain water storage facility.SOLUTION: A storage infiltration facility has a storage space formed by arranging unit members underground. The unit member is a rectangular parallelepiped formed by square or rectangle planes. Stacked multiple unit members are arranged in every direction keeping arbitrary distance between adjacent stacked unit members, and adapter pieces are attached to a central part on a side edge or four corner parts of each unit member. Mutually stable fixation of the unit members arranged in every direction keeping arbitrary distance between adjacent unit members is ensured by attaching a horizontal rail for ensuring mutual fixation in a horizontal lateral direction, a horizontal rail for ensuring mutual fixation in a horizontal direction toward the back and a column body for ensuring mutual fixation in a height direction through the adapter pieces.SELECTED DRAWING: Figure 1
