Problems solved by technology

In the traditional mooring system, the longitudinal adjustment cable set and the horizontal adjustment cable set in the traction steel wire rope set 1' are directly connected to the winch 4' and the anchor head 2', wherein, along the vertical adjustment cable set control pipe section 100' Longitudinal movement distance will make the winch 4' need a larger power (because the angle α' is larger, the lateral component force is larger, so if you want to pull the pipe joint 100'

Abstract

The invention discloses a mooring system for pipe joint sinking, and belongs to the technical field of tunnel engineering. The mooring system for pipe joint sinking comprises an anchor head set, a winch set, a mooring rope set, a longitudinal transfer supporting assembly and a transverse transfer supporting assembly. The anchor head set is arranged on the periphery of a pipe joint. The winch set is arranged on the pipe joint. The mooring rope set comprises a longitudinal cable adjusting set and a transverse cable adjusting set, one ends of the longitudinal cable adjusting set and the transverse cable adjusting set are wound on the winch set to be connected, the other ends of the longitudinal cable adjusting set and the transverse cable adjusting set are connected with the anchor head set,the longitudinal cable adjusting set is used for adjusting the longitudinal distance of the pipe joint, and the transverse cable adjusting set is used for adjusting the transverse distance of the pipejoint. The longitudinal transfer supporting assembly is arranged on the pipe joint and can adjust the distance between the longitudinal cable adjusting set and the top of the pipe joint in the vertical direction and adjust the ratio of component force of the longitudinal cable adjusting set in the longitudinal direction to component force of the longitudinal cable adjusting set in the transversedirection. The transverse transfer supporting assembly is arranged on the pipe joint and can adjust the distance between the transverse cable adjusting set and the top of the pipe joint in the vertical direction.

Description

technical field [0001] The invention relates to the technical field of tunnel engineering, in particular to a mooring system for pipe joint sinking. Background technique [0002] For the underwater installation and construction of immersed tunnels, especially when it involves the installation and construction of pipe joints of offshore immersed tunnels, mooring systems need to be used to control the sinking and docking of pipe joints. [0003] Because the pipe joint is very heavy, when the pipe joint sinks into the sea, it will generally be subjected to horizontal water flow. The traditional mooring system is to set traction wire cables and winches in the front and back directions (longitudinal) and left and right directions (horizontal) of the pipe joints. Pull to drag the pipe joint to move, and then adjust the moving distance of the pipe joint in the front-back direction and left-right direction. Specifically, such as figure 1 with figure 2 As shown, the mooring syste...
