Intercepting well for confluence pipeline

The utility model discloses a converging pipeline catch basin, and belongs to the technical field of sewage treatment. A confluence pipeline catch basin comprises a barrel and a submersible sewage pump and further comprises a well lid located at the top of the barrel, a water level detector is arranged below the well lid, the submersible sewage pump is located at the bottom of the barrel, a sewage pipe is arranged on one side of the submersible sewage pump, and a control valve is arranged in the middle of the sewage pipe. In order to solve the problems that in the using process of a movable filter frame, movable parts are prone to corrosion and rusting and garbage is prone to being hung, a movable door is made to move up and down in a rail through a hydraulic machine, so that opening and closing of an intercepting pipe and an overflow pipe are controlled, and the intercepting effect of the intercepting well is easily improved when the rainwater amount of the intercepting well is different. And the problems in
