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 tube sinking device capable of buffering, which includes a guide piece and a sinking assembly. The guide piece has at least a partial structure for being inserted into the bottom of the water; the sinking assembly includes a connecting frame and a sinking body, and the connecting frame It includes a frame body and three frame side seats. The frame body includes a first frame body and a second frame body. The first frame body is connected to the main pipe section, and the second frame body is connected to the pipe connection section; the first frame body and the second The frame body is equipped with a telescopic adjustment assembly, the height of the first frame body and the second frame body in the direction of the extension of the guide can be adjusted, and two of the three frame side seats are connected to the first frame body and the second frame body. The frame body is arranged oppositely, and the other frame side seat is connected between the two frame side seats that are oppositely arranged; the three frame side seats, the first frame body and the second frame body are enclosed to form a storage tank, and the sinking The storage body is embedded in the accommodating groove, is connected with the guide piece, and can move along the extending direction of the guide piece. The technical scheme of the invention improves the construction precision of sinking and placing immersed tubes.

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...
