When rainwater on the stop block 3 flows to the drainage groove 31, the rainwater is drained to the through hole in the middle of the stop block 3 under the action of gravity, so that the rainwater utilization rate of the dewatering well 21 is improved.

Referring to fig. 2 and 3, in the actual use process of the dewatering well 21, in order to facilitate the maintenance worker to repair the buoy, in this embodiment, the stopper 3 is detachably disposed. Specifically, a fixing seat 61 is installed on the circumferential side of the block 3, a bolt 62 is installed on the fixing seat 61, and the block 3 is fixed on the inner side wall of the dewatering well 21 through the bolt 62, so that the problem that the buoy is inconvenient to overhaul is solved.

In addition, in order to perform the intercepting process on the rainwater having entered the closed space, a float is provided in the present embodiment, so that the rainwater in the closed space needs to be subjected to the intercepting process to flow into the drain pipe 22.

A water outlet is formed in the side wall of the first floating block 41 close to the drain pipe 22, and the water outlet is matched with the opening of the drain pipe 22. In addition, a filter screen 413 for filtering rainwater is installed at the side wall of the second water permeable hole 412, and a first water permeable hole 421 is opened at the outer edge of the top of the second floating block 42.

After the rainwater flowed into precipitation well 21 through first hole 421 of permeating water, the water level of diapire in precipitation well 21 constantly risees for first floating block 41 drives connecting block 43 and the come-up of second floating block 42, until second floating block 42 and dog 3 looks butt, through the height of pre-adjustment connecting block 43 and the aperture of hydrophobic chamber 411, can make when second floating block 42 and dog 3 looks butt highly just with drain pipe 22's high looks adaptation hydrophobic chamber 411, thereby make partial rainwater pass through second hole 412 of permeating water and enter into behind hydrophobic chamber 411, can flow into in drain pipe 22 at last.

In the actual use process of the precipitation well 21, the precipitation well 21 is not too deep normally due to safety considerations, so that the water storage amount of the precipitation well 21 is very limited, and when a heavy rain is continuously encountered, the stored water stored in the precipitation well 21 easily overflows the precipitation well 21, so that a considerable amount of rain water cannot flow into the reservoir. In order to increase the water storage capacity of the dewatering well 21, an overflow tank 51 is dug in the foundation 1 on one side of the dewatering well 21, the overflow tank 51 is communicated with the dewatering well 21 through an overflow pipe 52, meanwhile, an opening of the overflow pipe 52 on the inner side wall of the dewatering well 21 is positioned above the stop block 3, and the overflow pipe 52 is arranged in a horizontal direction in an inclined mode, specifically, in the vertical direction, one end, close to the overflow tank 51, of the overflow pipe 52 is lower than one end, close to the dewatering well 21, of the overflow pipe 52.

When the water level in the dewatering well 21 rises to the opening of the overflow pipe 52 close to one end of the dewatering well 21, the excess water in the dewatering well 21 can be discharged into the overflow tank 51 through the overflow pipe 52
