Description

A device for directional dredging and slag removal of municipal drainage pipelines

technical field

The utility model relates to the technical field of municipal drainage, in particular to a device for directional dredging and slag removal of municipal drainage pipelines.

Background technique

Municipal drainage pipes are public infrastructure for collecting and transporting sewage, waste water and rainwater. In the process of urbanization in my country in recent decades, a large number of municipal drainage pipes and their ancillary facilities have been newly built in cities, which constitute the "underground" of urban operation. Bloodline". Due to the lack of effective dredging and operation and maintenance management of municipal drainage pipes for many years, the silt inside the drainage pipes is serious. On the one hand, the flow capacity of the drainage pipes is weakened, resulting in poor drainage and even urban waterlogging. , the organic matter in the silt produces H ₂ S, methane and other toxic gases and acidic substances under the action of microorganisms, which corrodes the pipeline and causes sewage to leak and pollute the groundwater. At present, winch dredging is a common mechanical dredging method for drainage pipelines in Shanghai, Guangzhou, Tianjin, Wuhan and many other cities in my country. Its main equipment includes winches, pulley frames and communication cattle. This method uses bamboo chips to pass through the pipeline that needs to be cleared, and uses the winch on the inspection well at both ends of the pipeline to reciprocate the wire rope, and then uses the ditching cow to pull the sludge and other silt out of the pipe and push it into the downstream inspection well, and finally operate Workers go down the well to clean up the silt. Winch dredging is suitable for municipal drainage pipelines with inspection wells at both ends. For long-distance closed drainage pipelines, it cannot be dredged, and manual operation is required. The working environment is harsh and the equipment is inconvenient to operate, which is likely to cause safety accidents.
