Dredging device and method suitable for drainage pipeline under urban roadway

Abstract

The invention discloses a dredging device and method suitable for a drainage pipeline under an urban roadway. The dredging device and method solve the problem in the prior art that the existing manualdredging in a well is high in labor cost and energy consumption and have the advantages of simple feasible structure and high dredging efficiency. The device suitable for the drainage pipeline underthe urban roadway comprises a casing. A pedal is arranged on the top of the casing, and a plurality of fixed teeth are arranged on the circumference of the drainage pipeline, and the bottom of the pedal is provided with a transmission rod penetrating the casing to the side of the pipeline. An elastic member is sleeved on the top of the transmission rod, the bottom of the elastic member is fixedlyconnected to the casing through a fixing plate, and the top of the elastic member is detachably connected with the lower surface of the pedal. The transmission rod is provided with an active node to facilitate resetting. External force drives the elastic member to push the transmission rod through the pedal, and further the transmission rod and the fixed teeth are matched to push the drainage pipeline to rotate to avoid siltation in the underground drainage pipeline.

Description

technical field [0001] The invention relates to the field of municipal drainage, in particular to a dredging device and method suitable for drainage pipes under urban roadways. Background technique [0002] The municipal drainage pipeline system is a very important infrastructure in today's cities. In order to provide people with a safe and comfortable production and living environment, the drainage pipeline system must effectively collect and transport domestic sewage, industrial wastewater and atmospheric precipitation, and timely and reliably However, with the continuous development of the city and the long-term operation of the pipeline, the poor drainage caused by siltation and blockage will become more and more serious, which will have a great impact on the normal operation of the city, and even cause serious urban waterlogging during the flood season. . Therefore, it is particularly important to clean up the sludge in time. [0003] Now the traditional municipal pip...

AI Technical Summary

Problems solved by technology

[0004] 1. The winch dredging method needs to be completed manually. The very harsh working environment in the mine brings great inconvenience to the workers, endangers the health of the workers, and even endangers the lives of the workers.

[0005] 2. The high-pressure water jet desilting method requires large water consumption and relatively high cost

[0006] 3. Water flushing and dredging method. Due to poor control of the source of domestic drainage pipes and other reasons, there are more entangled garbage in the sewage, resulting in insufficient water storage and poor drainage, which makes it lose its existing functions.

[0007] 4. The robot dredging technology has a complex structure, slow walking and low efficiency, and is still under theoretical research

[0008] Therefore, the prior art requires manual downhole work, or other means to work, and there is a problem of low efficiency. It is necessary to study a kind of desilting device suitable for drainage pipes under urban roadways.
