The invention discloses an immersed tube sinking device capable of resisting water flow and buoyancy. The sinking tube sinking device comprises a guide member and a sinking assembly. The guide member has at least a partial structure for being inserted into the water bottom. There is a liquid accommodating cavity, and the guide member is provided with a water inlet hole that communicates the liquid accommodating cavity and the outside world; the sinking assembly includes a connecting frame and a sinking body, and the connecting frame is used to be fixedly connected with the sinking tube, so The sinking body is connected to the side of the connecting frame away from the sinking tube, the sinking body is connected with the guide piece, and can move along the extending direction of the guide piece. The technical scheme of the present invention can improve the construction accuracy of the immersed tube laying and at the same time improve the efficiency of the immersed tube laying.
Description
technical field [0001] The invention relates to the technical field of tunnel immersed tubes, in particular to an immersed tube sinking device capable of resisting buoyancy of water flow. Background technique [0002] At present, the immersed tube is generally lowered to the bottom of the water by double barge hoisting method when installing the immersed tube. That is to say, two barges are connected to the opposite ends of the immersed tube through the suspension cables, and after the immersed tube is floated to the installation position, the sinking of the immersed tube to be installed is realized by controlling the lifting of the suspension cable, thus completing the sinking. Tube sinking process. However, during the sinking process, since the sinking barge is easily affected by the impact of the water flow, the immersed tube deviates above the preset sinking position when it is on the water surface, and then deviates from the preset sinking position in the subsequent si...
