Abstract

The present application belongs to the field of municipal sewage pipeline engineering, and particularly relates to a concrete sewage pipeline system facilitating dredging. The present application designs the lumen of the concrete sewage pipeline as an oval shape, and a reserved hole through which a main water pipe passes is arranged in the concrete sewage pipeline. A hole groove in communication with the reserved hole is arranged on the inner pipe wall. The main water pipe located in the hole groove is connected with branch water pipes. The branch water pipes are connected with high-pressure nozzles. Adjacent concrete sewage pipelines are connected together through a gable and a groove. Adjacent main water pipes are connected together through a rubber transition joint. The main water pipe in the inspection well is connected with a high-pressure water pump to realize the dredging operation in the concrete sewage pipeline. Workers do not need to work in the well, and the safety is high. The dredging efficiency is greatly improved.
