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 a recyclable immersed tube sinking device. The immersed tube sinking device includes a guide piece and a sinking assembly. The guide piece has at least a part of structure for being inserted into the bottom of the water; Put the body, the connecting frame includes the frame body and three frame side seats, the frame body includes the first frame body and the second frame body, the first frame body and the pipe main body section are detachably connected, and the second frame body and the pipe connection section are detachable connection, two of the three frame side seats are connected to the first frame body and the second frame body, and are 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 an accommodating groove, one end of the sinking body is embedded in the accommodating groove, the other end can be connected with the guide piece, and can be moved along the direction of the guide piece Movement in the direction of extension. The technical scheme of the invention can improve the construction precision of the sinking and laying of the immersed tubes, and can be recovered after the sinking and laying of the immersed tubes is completed.

Description

technical field [0001] The invention relates to the technical field of tunnel immersed tubes, in particular to a recyclable 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 th...
