Pipe dredging device

Abstract

The invention discloses a pipeline dredging device. The pipeline dredging device is characterized in that the pipeline dredging device comprises a dredger, the dredger comprises a base and a baffle, the cross section of the base is in an arc shape, the base axially extends by a selected length, the base comprises an inner surface and an outer surface which is opposite to the inner surface, the baffle is arranged on the inner surface of the base and protrudes out of the inner surface, the dredger moves along a blocked pipeline, and the baffle can push sludge in the blocked pipeline to a designated position. By means of the pipeline dredging device, the pipeline dredging effect can be effectively improved, the amount of sludge in the pipeline underground can be greatly lowered, the sludge rate in the pipeline is controlled below 5%, smoothness of the pipeline is ensured, and drainage efficiency of an urban drainage system is improved.

Description

technical field [0001] The invention relates to the field of road maintenance, in particular to a pipe dredging device for an urban road drainage system. Background technique [0002] In recent years, the problem of urban waterlogging has continuously appeared in various places, which directly endangers the safe operation of the city and the safety of people's lives, and also causes huge economic losses. There are many reasons for urban waterlogging, such as excessive rainfall, imperfect drainage systems, and damaged drainage pipes. In recent years, typhoons and heavy rains have occurred in coastal areas, and the rainfall in the flood season has increased year by year. The original urban drainage system standards have been unable to meet the current drainage needs. Coupled with the increasing intensity of urban construction, the sand and soil required for the project will easily fall and accumulate on the road during transportation, and flow into the drainage system with th...

AI Technical Summary

Problems solved by technology

Due to the disc-shaped structural feature of the baffle 02, the baffle 02 cannot be kept stable during the movement

The silt in the lower layer can easily tilt the baffle 02, so the baffle 02 cannot push the silt to move

like figure 2 As shown, the inclined baffle plate 02 cannot exert thrust on the mud 06 in the lower layer, and cannot concentrate it to the designated position, resulting in poor cleaning effect, high labor intensity and low work efficiency
