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. The immersed tube sinking device 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 assembly. The sinking body, the connecting frame is used for fixed connection with the immersed tube, the sinking body is detachably connected to the side of the connecting frame away from the immersed tube, the sinking body is connected to the guide , and can move along the extension direction of the guide. The technical scheme of the invention can improve the construction precision of the sinking and placing of the immersed tube.

Description

technical field [0001] The invention relates to the technical field of tunnel immersed tubes, in particular to an immersed tube sinking device. 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 location of the sinking ...
