The invention discloses a hydraulic self control flow converging pipe network flow cut-off control well, which comprises a well body, wherein a rain and sewage flow converging water inlet pipe is arranged at the left end of the well body, the right end of the well body is provided with a water outlet pipe, a primary rain overflow weir, a slag blocking floating tube and a multi-stage adjustable overflow plate are sequentially arranged on the flow passage of the well body from the left side to the right side, a sewage flow cut-off pipe is arranged at the bottom of the side wall of the well body between the rain and sewage flow converging water inlet pipe and the primary rain overflow weir, a floating tube flow cut-off check valve is arranged on the sewage flow cut-off pipe, a primary rain flow cut-off pipe is arranged at the bottom of the side wall of the well body arranged between the primary rain flow overflow weir and the multi-stage adjustable overflow plate, and a flow cut-off check valve is arranged on the primary rain flow cut-off pipe. The floating tube flow cut-off check valve is arranged at an inlet of the sewage flow cut-off pipe, in addition, the flow cut-off check valve is arranged at the inlet of the primary rain flow cut-off pipe so that the flow rate of the flow cut-off sewage and the primary rain can be controlled, and in addition, the reverse flow of the sewage and the primary rain can be prevented; the slag blocking floating tube is used for blocking slag, so the blocking phenomenon is avoided, the adjustable height of the discharge water level can be realized through the multi-stage adjustable overflow plate, further, the effective separation of the primary rain is realized, and the primary rain can be conveyed to sewage treatment plants to the maximum after the flow cut-off operation.
