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 with an adjustable distance. The immersed tube sinking device comprises a guide part, a sinking assembly and a driving assembly, wherein at least part of 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 is used for beingfixedly connected with an immersed tube, and the sinking body is slidably arranged on the connecting frame in the direction close to or away from the guide part and is connected with the guide part in a lifting mode; and the driving assembly is arranged on the connecting frame and is connected with the sinking body, and the driving assembly drives the sinking body to slide. According to the technical scheme, the sinking precision of the immersed tube can be improved, and meanwhile, the use convenience of the immersed tube sinking device can be improved, and the safety of the guide part in butt joint with the sinking assembly 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 with adjustable distance. 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...
