The immersed tube tunnel is an underwater tunnel built by floating and transporting a plurality of prefabricated sections to the sea surface (river surface) site respectively and sinking and installing the prefabricated sections in a dredged foundation trench one by one. In order to avoid local high points of the foundation, the stress of the bottom plate of the immersed tube is uniform, and a gravel foundation bed with high flatness requirement needs to be laid in the immersed tube foundation groove. The time required for the foundation bed to be laid from the start to the installation of the pipe joints may increase further, subject to levelling, the progress of the floating and other factors. Because the sand content of the near-shore water area is usually higher, under the action of a plurality of factors such as water flow speed, sand content change, water body disturbance and the like, the back silting of the foundation bed is increased, and even the silting accumulation condition is caused. The deposited sludge can adversely affect the construction of the immersed tube and the stress on the structure. In order to avoid the influence of the sludge on the immersed tube tunnel, the foundation bed with the accumulated sludge must be subjected to dredging treatment.
