Urban rivers are the main way of urban drainage and flood control, and also one of the main sources of urban domestic and industrial water. Generally, the water flow of urban rivers is relatively gentle and the drop is small, resulting in a large amount of river silt easily deposited on the river bottom, accumulating into river silt that is difficult to remove; and due to the complexity and variety of urban waste, river silt deposits, affecting river flood control, drainage, water supply, navigation, etc. Various functions.

In order to improve the beauty of urban rivers, facilitate management and maintenance, and reduce potential safety hazards, hard slope protection or retaining walls are often built on both sides of the river in urban rivers, and hard river bottoms are also laid on the bottom of some urban rivers. Since both sides of urban rivers are built as hard slope protection or retaining walls, the dredging of urban rivers is generally limited to the cleaning of river bottom sludge. Existing urban river silt cleaning mainly includes the following methods: desilting with water, dredging in dry field and solidifying silt. Among them, the dry site dredging construction is fast and the dredging effect is relatively thorough, but it is necessary to adopt measures such as river channel water regulation and diversion or unknown cofferdams to realize dry site operations.
