When the filter basket 22 is arranged at the bottom end of the seepage well 2, the side wall of the filter basket can also shield the one-way valve 6, so that water flowing out of the one-way valve 6 is also filtered; when the precipitation amount of the outside is large and the water level in the water seepage well 2 is high, the water pressure in the water seepage well 2 presses the valve plate 27 to apply force to the valve plate 27, so that the valve plate 27 moves towards the one-way underframe 25, the one-way spring 28 and the telescopic rod 26 are compressed until the valve plate 27 is separated from the one-way hole 23, and the water in the water seepage well 2 flows to the water storage cavity 5 from the one-way hole 23; when the water level in the water seepage well 2 is reduced to a certain degree, the water pressure is reduced, the one-way spring 28 rebounds to press the valve plate 27 back into the one-way hole 23, and the one-way hole 23 is sealed; the setting of check valve 6 can be according to the speed that the water level regulation precipitation in the infiltration well 2 flowed into water storage chamber 5, prevents the precipitation backward flow in the water storage chamber 5 simultaneously, can adapt to the precipitation condition of difference.

In a further optimized scheme, a step 29 is arranged in the one-way hole 23, and the end face, facing the one-way hole 23, of the valve plate 27 is abutted against the step 29; a seal ring 30 is fixed to an end surface of the step 29 abutting against the valve plate 27.

When the rainfall is large, the control push rod 36 retracts to drive the lifting plate 4 to lower, and the lifting plate is separated from the water inlet hole 34 to increase the water flow of the fixing plate 3.

In a further optimized scheme, a filter frame 37 is arranged at the connecting position of the water storage cavity 5 and the multiplexing pipe 9, the multiplexing pipe 9 is communicated with the inner cavity of the filter frame 37, and the end face of the filter frame 37 is arranged in a concave manner; the inner cavity of the filter frame 37 is also communicated with a blow-washing pipe 38. The filter frame 37 can filter the water entering the multiplexing pipe 9 again, so that the blockage caused by the impurities and various microorganism blocks in the water storage cavity 5 entering the multiplexing pipe 9 is prevented; the end face of the filter frame 37 is arranged to be concave, so that the contact area with water is increased, and the filtering speed is increased; the purge tube 38 can blow compressed air or high pressure water to remove impurities blocking the filter frame 37.

the filter basket 22 is lowered to the lowest part of the water seepage well 2 along the positioning screw 21, and then the support assembly, the lifting plate 4 and the fixing plate 3 are installed in sequence.

When the precipitation is small, rainwater directly permeates into the ground layer 1 and is absorbed by the ground layer 1 for the growth of greening plants; when the rainfall is increased, the unit rainfall is larger than the permeability of the ground layer 1, runoff is formed on the ground, rainwater flows into the water seepage well 2 along the water seepage holes 33, and flows into the water storage cavity 5 after being filtered by the filter basket 22; when the precipitation is increased again, the precipitation per unit time is greater than the treatment capacity of the ground layer 1 and the seepage holes 33, accumulated water is formed on the ground, the lifting plate 4 is controlled to move downwards by the control push rod 36 at the moment, the water inlet holes 34 are communicated, the accumulated water flows into the seepage well 2 from the seepage holes 33 and the water inlet holes 34 together, and the depth of the accumulated water is reduced; when the water level in the infiltration well 2 rises, the valve plate 27 is pressed to the one-way bottom frame 25 by the water pressure, the one-way hole 23 is communicated, the rainwater in the infiltration well 2 flows to the water storage cavity 5 from the one-way hole 23 after being filtered by the filtering basket 22, and when the water level drops, the one-way spring 28 pushes the valve plate 27 back into the one-way hole 23 to seal the one-way hole 23 and prevent the rainwater in the water storage cavity 5 from flowing backwards.

The rainwater in the water storage cavity 5 enters the multiplexing cavity 8 after being filtered by the filter frame 37, and part of the rainwater in the city can be used with low requirement; when the water level in the water storage cavity 5 is too high, the emergency drain pipe 7 quickly drains the water in the water storage cavity 5 to nearby ditches, riverways and other water areas, so that the water storage cavity 5 is prevented from losing energy, and the water storage cavity 5 can be cleaned once by quickly draining the water.
