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

Disclosed in the present invention is an immersed pipe sinking apparatus. The immersed pipe sinking apparatus comprises a guide member and a sinking assembly; at least part structures of the guide member are inserted in the water bottom; the sinking assembly comprises a connection frame and a sinking body; the connection frame is fixedly connected to an immersed pipe; the sinking body is detachably connected to the side, deviated from the immersed pipe, of the connection frame; and the sinking body is connected to the guide member, and can move in the extension direction of the guide member. The technical solution of the present invention can improve the sinking construction precision of the immersed pipe.

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 double barge hoisting method is generally used to lower the immersed tube to the bottom of the water when installing the immersed tube. That is to say, two barges are connected to the opposite ends of the immersed pipe through suspending cables, and after the immersed pipe is floated to the installation position, the immersed pipe to be installed can be sunk by controlling the lifting and lowering of the suspending cable, thereby completing the sinking. The settling process of the tube. However, during the sinking process, since the sinking barge is easily affected by the impact of the water current, the immersed tube deviates from 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 placem...
