Abstract

The invention provides a gravel bed desilting device and desilting method. Silt on the surface of a gravel bed can be quickly and completely removed on the condition that the gravel bed is not disturbed. The device is installed on a desilting ship and comprises a desilting sucker and a moving unit used for moving the desilting sucker; the desilting sucker comprises a sucker body and a plurality of suction pipes made of a soft material, and the suction pipes are arranged at the bottom of the sucker body so as to make contact with the surface of the gravel bed; the moving unit is installed on the desilting ship and comprises a lowering part used for lowering the desilting sucker, and the lowering part is fixedly connected with the desilting sucker and can rise and fall relative to the desilting ship.

Description

technical field [0001] The invention belongs to the technical field of deep-water foundation bed construction, and in particular relates to a gravel bed dredging device and a dredging method. Background technique [0002] In the construction of immersed tube tunnels, in order to make the bottom surface of the tunnel foundation groove smooth, foundation treatment is usually required. At present, the commonly used foundation treatment methods include the first laying method and the second filling method. The first laying method refers to laying the crushed stone bed before sinking the immersed pipe. Compared with the post-filling method, the first laying method has the advantages of small post-construction settlement and high construction efficiency. However, when adopting the pavement-first method, due to the large amount of sand in the water area and the presence of a certain thickness of silt on the original mud surface of the foundation bed, the disturbance of the water f...
