物が攪拌されて浮上することはない。 Rainwater mixed with fallen leaves, dirt, etc. flows through hole 8 of lid 8.
When the debris falls from the water collection section 32 into the water collection section 32, the filter 7 disposed within the water collection section 32 captures large debris such as fallen leaves and dirt. The rainwater flowing down inside the vertical pipe 3 flows into the lower part of the basin body 1, and fine earth and sand are separated and deposited on the basin bottom part 2. At this time,
Rainwater passes between the lower end 31 of the vertical pipe 3 and the cylindrical body 41 and flows into the lower part of the basin body 1 as indicated by the arrow in the figure, so that sediments such as earth and sand deposited on the basin bottom 2 are removed. It will not be stirred and floated to the surface.

る頻度が大幅に低減した。(Operations and Effects of the Invention) As described above, the present invention provides a predetermined distance between the bottom end of the vertical pipe and the bottom of the vertical pipe vertically installed in the main body of the cellar, and also provides a predetermined distance between the outer periphery of the lower end. Since it is covered with a cylinder with a gap, rainwater flowing down inside the vertical pipe passes between the bottom end of the vertical pipe and the cylinder and flows into the lower part of the main body of the basin, and when rainwater flows in, it flows into the bottom of the basin. There is no need to stir up sediment such as earth and sand and bring it to the surface again. Therefore, the flat filter installed between the inner periphery of the basin body and the outer periphery of the vertical pipe is less likely to be clogged with dirt, etc., and the frequency of replacing the filter is significantly reduced.
