Description

Technical Field

[0001] The present application relates to the technical field of dredging devices, and in particular to a rainwater and sewage diversion dredging device. Background Art

[0002] In the urban rainwater and sewage separation pipe network, due to sedimentation and other factors, some silt will adhere to the bottom side of the inner wall of the pipe. Pipeline desilting is to dredge the pipe, clean the silt in the pipe, and keep it unobstructed for a long time to prevent urban waterlogging. Pipeline desilting has become an important task that cannot be ignored by the drainage department. A large amount of debris and cement sand from infrastructure construction sites will cause precipitation and siltation in the drainage pipe, which will cause pipe blockage. If the pipe is not desilted and dredged, it will cause sewage overflow, pollute the environment, and bring troubles to people's lives.

[0003] With respect to the above-mentioned related technologies, the inventor believes that with the acceleration of urbanization, the discharge of rainwater and sewage is increasing day by day, and the phenomenon of rainwater and sewage confluence is serious, which has brought great pressure to the urban drainage system. At present, there are some rainwater and sewage diversion and silt removal devices on the market, most of which adopt simple interception and diversion methods, which are not thorough enough for the cleaning of sludge, easy to clog, and complicated to operate and high in maintenance cost. Therefore, it is necessary to develop a new type of rainwater and sewage diversion and silt removal device to solve the problems existing in the prior art;

[0004] The above information disclosed in the background technology is only used to increase the understanding of the background technology of the present application, and therefore, it may include information that does not constitute the prior art known to ordinary technicians in the field.
