Preferably, four open drainage ditches are formed around the bottom of the foundation pit, and the water collecting well is communicated with the open drainage ditches.

Preferably, a top cover is installed at the top end of the filter cylinder, and a water pumping pipe penetrates through the middle of the top cover.

Preferably, four angles in the sump pit all install external corner branch, the both sides of curb plate are connected respectively in two external corner branches.

Preferably, the connecting block is fixedly connected with the clamping block through a bolt A.

Preferably, the inner wall of the filter cylinder is provided with two ring sleeves B, and the ring sleeves B are detachably connected with the ring sleeve A.

Preferably, the ring sleeve B is fixedly connected with the ring sleeve A through a bolt B.

Compared with the prior art, the beneficial effects of the utility model are that:

1. the utility model has the advantages that the ring sleeve A sleeved on the outer wall of the filter cylinder is connected with the four connecting blocks at the periphery of the ring sleeve A respectively connected with the embedded fixture blocks in the clamping grooves on the side plates, so that the filter cylinder is fixed in the sump well, and the sand generated by collapse is prevented from pushing the filter cylinder to turn on one side, thereby preventing the filter cylinder from losing the effect of isolating the sand;
