Abstract

The invention discloses an immersed tube sinking device capable of buffering. The immersed tube sinking device capable of buffering comprises a guide part and a sinking assembly, wherein at least partof the structure of the guide part is used for being inserted into the water bottom; the sinking assembly comprises a connecting frame and a sinking body, the connecting frame comprises a frame bodyand three frame side seats, the frame body comprises a first frame body and a second frame body, the first frame body is connected with a tube main body section, and the second frame body is connectedwith a tube connecting section; the first frame body and the second frame body are provided with telescopic adjusting assemblies, the heights of the first frame body and the second frame body in theextending direction of the guide part are adjustable, two frame side seats in the three frame side seats are connected to the first frame body and the second frame body and are oppositely arranged, and the other frame side seat is connected between the two oppositely arranged frame side seats; an accommodating groove is defined by the three frame side seats, the first frame body and the second frame body, and the sinking body is embedded in the accommodating groove, connected with the guide part and capable of moving in the extending direction of the guide part. According to the technical scheme, the sinking construction precision of an immersed tube 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 buffering. 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 sinking process. The loc...
