Deep foundation pit dewatering well assembly and blocking method thereof

The invention discloses a deep foundation pit dewatering well assembly and a plugging method thereof. The deep foundation pit dewatering well assembly comprises a well sleeve and a casing pipe. The water pump has the beneficial effects that when concrete is poured, the waterproof coiled materials are arranged at the pouring positions respectively, the water seepage probability after a rubber gasket of a flange plug is aged can be effectively reduced by adding a waterproof method, the water pump is convenient to replace and maintain in the rainfall period, and all the water pumps can be taken out during plugging, so that the cost is reduced; welding construction is not needed in the construction process, concrete pouring can be conducted immediately after the pump is disassembled, the flange plug is rapidly installed so as to achieve the rapid plugging effect, and compared with other methods, the well plugging process is easy to operate, few in step, high in speed and good in effect. 本发明公开了一种深基坑降水井组件及其封堵方法，包括井
