[0037] Working principle of a gate well used in urban drainage system:

[0038] During daily sewage discharge, the first outlet pipe 3 is normally open, and the second outlet pipe 4 is normally closed. Sewage enters from the water inlet pipe 2 and then enters the filter screen 54 for filtration. After the filter screen 54 filters the water flow from the water inlet pipe 2, the water flow enters the water discharge area, and then the water flow passes through the silt-turning shell 651 and then discharges the sewage through the first outlet pipe 3.

[0039] When the rainfall is heavy, the first outlet pipe 3 is in a closed state and the second outlet pipe 4 is in an open state. Rainwater enters from the inlet pipe 2 and then enters the filter net 54 for filtration. After the filter net 54 filters the water flow coming in from the inlet pipe 2, the water flow enters the discharge area again, and then the water flow is discharged into the city river through the second outlet pipe 4.

[0040] It should be noted that the present application does not improve the control program, and the control program and electrical components involved are all prior art.

[0041] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention.
