At this time, it can be formed into any shape such as a circular column in a plane, and the number of divisions of the filling member can also be divided into any number, such as four, at any position. The dividing method may be either vertical division or horizontal division, but basically, it forms a storage part for rainwater infiltration masu, and a void that connects the inner surface that partitions this storage part and the outer surface that is in contact with the surrounding ground. By forming the, it is possible to adopt any form that allows the rainwater introduced into the rainwater permeating trough to permeate into the surrounding ground from the peripheral surface including the bottom surface of the filling member.

As described above, a locking portion that locks adjacent blocks of the filling member main body 11 to each other, for example, a locking protrusion 18 a and a locking hole portion 18 b may be formed on the joint surface 18 of the filling member main body 11. it can. As a result, the filling member 1 formed by being divided into a plurality of blocks can be accurately installed in the excavation hole. Since the earth pressure of the surrounding ground acts on the backfilled filling member 1 and the filling member 1 does not separate in the ground, the locking portions 18a and 18b make the filling member 1 an excavation hole. It is sufficient that the filling members 1 formed by being divided into a plurality of blocks have a locking strength such that the locking of the filling members 1 with each other is not released when they are installed inside.
