Problems solved by technology

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 sinking process. place, resulting in reduced construction accuracy of immersed tubes

Abstract

The invention discloses an immersed pipe immersion device capable of resisting water flow buoyancy. The immersed pipe immersion device comprises a guide piece and an immersion assembly. At least partof the structure of the guide piece is inserted in the bottom of the water, and a liquid accommodating cavity is formed in the guide piece; a water inlet hole is formed in the guide piece, and the liquid accommodating cavity communicates with the outer side through the water inlet hole; and the immersion assembly comprises a connecting frame and a immersion body, the connecting frame is used for fixed connection with an immersed pipe, the immersion body is connected to the side, away from the immersed pipe, of the connecting frame, and the immersion body is connected with the guide piece and can move in the extending direction of the guide piece. The technical scheme of the immersed pipe immersion device can improve the immersion construction accuracy of the immersed pipe, and meanwhile the immersion efficiency of the immersed pipe is improved.

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...
