Description

Technical Field

[0001] The utility model relates to the technical field of sludge collection, in particular to a sludge collection structure for an urban river. Background Art

[0002] Silt is a soft soil with a natural water content greater than the flow limit and a porosity greater than 1.5. It is a modern sediment formed under the conditions of slow water flow in bays, lakes or river bays with the participation of microorganisms. It is rich in organic matter, often gray-black, with low mechanical strength and strong compressibility. If there is silt in the foundation, it is easy to cause the building to sink;

[0003] According to the patent document: CN220202804U, a silt-clearing device for river channel management is disclosed, including a grip and a connecting column, the connecting column is fixedly installed on the top of the grip, and the outer wall of the connecting column is provided with a silt-clearing mechanism and a salvaging mechanism, and the silt-clearing mechanism includes an adjustment unit and a cleaning unit. The silt-clearing device for river channel management can adjust the position of the silt-clearing structure according to the depth of the river channel by setting the silt-clearing mechanism, thereby improving the silt-clearing efficiency of the device, solving the problem that the device proposed in the background technology is not convenient to adjust the silt-clearing structure according to the depth of the river channel, so that the device has certain limitations. By setting the salvaging mechanism, garbage and other debris in the river channel can be salvaged and collected while silting the river channel, thereby improving the overall environment of the river channel and improving the environment of the river channel.

[0004] The water in urban rivers is formed by the confluence of various tributaries, and the water in the tributaries will carry garbage and silt into the river. The garbage floats on the water surface and is cleaned by salvage, while the silt is deposited underwater and is inconvenient to clean. If it is not cleaned for a long time, it will cause blockage in the river.

When going deep into the river, a large amount of river water may be mixed in first, and a large amount of river water needs to be discharged before the silt can continue to be discharged, which affects efficiency.
