In order to implement the sustainable development strategy, departments at all levels have stepped up efforts to regulate rivers and waterways, and strongly supported dredging projects to improve waterway management. Currently, dredging machines and pipelines are usually used to clean up silt in rivers and waterways.

[0003] At present, in order to facilitate the use of existing dredging and conveying pipelines in waterways, plastic foam floats are needed to ensure that the pipelines float on the water surface. However, the installation volume is large, and the installation and disassembly are relatively cumbersome, which wastes a lot of manpower. In addition, the two existing conveying pipelines are mostly fixed together by screws or clamps, and tools are required for disassembly and assembly. The connection between the pipelines is relatively complicated and not convenient enough.

[0004] Based on this, the utility model designs a silt removal and conveying pipeline to solve the above problems. Utility Model Content
