Description

Technical Field

[0001] The utility model relates to the technical field of dredging equipment, in particular to a stirring dredging device which utilizes a dredging pump to cause underground pipeline discharge water to stir deposited sludge to form muddy water, then pumps out the muddy water, and finally realizes dredging. Background Art

[0002] The underground pipeline system, which is an important node in urban planning and construction, can discharge wastewater and rainwater generated in the city or transport it to sewage treatment plants for treatment, and plays an important role in urban pollution prevention, waterlogging prevention, and clean city appearance. As the underground pipeline system is connected to the ground, the sewer well is connected to the ground, so sand, dust, etc. usually fall into it and deposit to form silt, causing the underground pipeline, especially the pipeline under the sewer well, to be blocked. Therefore, it is necessary to remove the silt from the underground pipeline.

[0003] At present, in order to ensure the smooth drainage of the underground pipeline system, it is necessary to regularly use a dredging pump to clean the silt deposited in the underground pipeline. Since the silt has been deposited, it is difficult to directly use a dredging pump to extract the silt to achieve the dredging effect. The conventional operation is to first use high-pressure water to impact the silt to make it roll and form muddy water with water, and then use a dredging pump to pump out the muddy water, so as to achieve the effect of cleaning the silt. The process is very cumbersome, resulting in a waste of a lot of manpower and material resources; secondly, when the blockage is serious or there is a lot of silt, a large amount of high-pressure water is required for flushing, which is relatively wasteful of water resources.
