RAINWATER STORAGE AND INFILTRATION FACILITY
A unit member A includes a square flat plate (31) with a given thickness and hollow legs (32, 33) in a truncated cone shape being opened to contact surfaces (34) formed on the four corners and the flat plate. The contact surface is provided with an engaging convex portion (321) and an engaging concave portion (331) for mutually connecting with another unit member A. The engaging convex portion 321 of one unit member A and the engaging concave portion 331 of the other unit member A is placed facing each other to make a pair of unit members, and given numbers of the pair of unit members are assembled in the horizontal and vertical directions to construct a rainwater storage/infiltration facility. Since the contact surface has a step thereon, load can be supported by virtue of the step of the two lateral sides of the contact surfaces.
