Background technique

In the current urban construction, domestic sewage and rainwater are discharged through drainage pipes. There are various impurities in domestic sewage and rainwater, including sediment, leaves, hair, plastic bags, etc. These impurities enter the drainage pipes, often silting up the pipes, blocking the pipes in severe cases, seriously affecting the drainage capacity of the pipes, making the sewage unable to be drained in time, or even overflowing the pipes, causing urban public safety problems.

For pipeline blockage and siltation, it is necessary to perform pipeline dredging frequently to ensure the normal operation of the pipeline. Therefore, dredging is an important and frequent task. There are various techniques for pipeline dredging, such as winch dredging method, high pressure water jet dredging method, robot dredging technology and water scouring dredging method. All of these methods can achieve the purpose of removing the sludge and restoring the drainage capacity of the pipeline.

However, the cost of robot dredging and high-pressure water jet dredging is relatively high, and it is very expensive to implement such dredging on a large scale in urban pipelines. At present, the winch dredging used in most cities has certain safety hazards, and it needs to manually go down to install bamboo chips. However, the drainage pipeline environment is complex, and it is very dangerous to enter the pipeline manually. The water flushing and dredging method requires a large amount of water to flush the drainage pipes, which consumes a lot of water and causes a waste of water resources.
