Abstract
Description
Technical Field
[0001] The invention relates to the technical field of tunnel engineering, and in particular to a mooring system for pipe segment sinking. Background Art
[0002] During the underwater installation and construction of immersed tube tunnels, especially the installation and construction of offshore immersed tube tunnel segments, a mooring system is required to control the sinking and docking of the segments.
[0003] Since the pipe segment is very heavy, when it sinks into the sea, it is generally affected by the lateral water flow. The traditional mooring system is to set traction wire cables in the front-to-back direction (longitudinal direction) and the left-to-right direction (lateral direction) of the pipe segment, and the winch is used to drag the pipe segment to move, thereby adjusting the moving distance of the pipe segment in the front-to-back direction and the left-to-right direction. Specifically, Figure 1 and Figure 2 As shown, the mooring system includes a traction wire rope group 1', four anchor heads 2' arranged on the periphery of the pipe segment 100' and two measurement control towers 3' arranged at intervals on the top of the pipe segment 100'. The measurement control tower 3' is used to detect the sinking and floating state of the pipe segment 100' in real time to ensure that the pipe segment 100' sinks according to a preset posture. Three winches 4' are arranged on the measurement control tower 3', one of which controls the left and right movement of the pipe segment 100', and the other two winches 4' control the front and back movement of the pipe segment 100'. The traction wire rope group 1' includes a longitudinal adjustment cable group and a transverse adjustment cable group. The longitudinal adjustment cable group is used to connect with the pipe segment 100' and control the longitudinal movement of the pipe segment 100', and the transverse adjustment cable group is used to connect with the pipe segment 100' and control the transverse movement of the pipe segment 100'. The longitudinal adjustment cable group and the transverse adjustment cable group in the traction wire rope group 1' in the traditional mooring system are directly connected to the winch 4' and the anchor head 2'. When the longitudinal adjustment cable group controls the longitudinal movement distance of the pipe segment 100', the winch 4' requires a larger power (because the angle α' is larger, the transverse component of force is larger, so if the pipe segment 100' is to be pulled longitudinally, the total force will be larger) to move the pipe segment 100' longitudinally; and when the traction wire rope group 1' is pulling the pipe segment 100' to move, the top surface of the pipe segment 100' will be rubbed over a large area. Generally, a sacrificial anode layer is provided on the top surface of the pipe segment 100', and the friction of the wire rope group 1' will wear away this sacrificial anode layer.
[0004] Therefore, there is an urgent need for a mooring system for pipe segment sinking that reduces the longitudinal force applied by the winch and reduces the probability of the sacrificial anode layer on the top of the pipe segment being worn, so as to solve the above-mentioned technical problems existing in the prior art.

In addition, the terms "first" and "second" are only used to distinguish in the description and have no special meaning.
[0037] like Figure 3 to Figure 5 As shown, this embodiment provides a mooring system for pipe segment sinking, which includes an anchor group 1, a winch group 2, a cable group 3, a longitudinal transfer support assembly 4 and a transverse transfer support assembly 5, wherein the anchor group 1 is arranged around the pipe segment 100; the winch group 2 is arranged on the pipe segment 100; the cable group 3 includes a longitudinal adjustment cable group 31 and a transverse adjustment cable group 32, and the longitudinal adjustment cable group 31 and the transverse adjustment cable group 32 are both wound around the winch group 2 at one end and connected to the anchor group 1 at the other end. The longitudinal adjustment cable group 31 is used to adjust the pipe segment 100. The transverse adjustment cable group 32 is used to adjust the distance of the pipe joint 100 along the longitudinal direction; the longitudinal transfer support assembly 4 is arranged on the pipe joint 100, and the longitudinal transfer support assembly 4 can adjust the distance between the longitudinal adjustment cable group 31 and the top of the pipe joint 100 along the vertical direction, and adjust the ratio of the longitudinal component force of the longitudinal adjustment cable group 31 to the transverse component force; the transverse transfer support assembly 5 is arranged on the pipe joint 100, and the transverse transfer support assembly 5 can adjust the distance between the transverse adjustment cable group 32 and the top of the pipe joint 100 along the vertical direction.
[0038] The longitudinal transfer support assembly 4 is provided to adjust the vertical distance between the longitudinal adjustment cable assembly 31 and the top of the pipe segment 100, thereby reducing the friction of the longitudinal adjustment cable assembly 31 on the top of the pipe segment 100 during the process of the winch assembly 2 pulling the longitudinal adjustment cable assembly 31, thereby reducing the probability of the sacrificial anode layer on the top of the pipe segment 100 being worn, and adjusting the ratio of the longitudinal force component of the longitudinal adjustment cable assembly 31 to the lateral force component, so that the ratio value is larger. When the ratio value is larger, Figure 3The smaller the α value is, the larger the longitudinal component force is, so as to reduce the longitudinal force applied by the winch; the lateral transfer support assembly 5 can adjust the vertical distance between the transverse adjustment cable group 32 and the top of the pipe segment 100, thereby reducing the friction of the transverse adjustment cable group 32 on the top of the pipe segment 100 when the winch group 2 pulls the transverse adjustment cable group 32, thereby reducing the probability of wear of the sacrificial anode layer on the top of the pipe segment 100.
[0039] Specifically, the longitudinal transfer support assembly 4 includes a plurality of cable guides 41, which are arranged on the pipe joint 100, and the longitudinal adjustment cable group 31 is connected to the anchor head group 1 by winding around the cable guides 41. The arrangement position of the cable guides 41 can reduce the lateral component of the longitudinal adjustment cable group 31, that is, reduce Figure 3 , and adjust the vertical distance between the longitudinal adjustment cable group 31 and the top of the pipe segment 100. Optionally, in order to minimize the contact between the longitudinal adjustment cable group 31 and the top surface of the pipe segment 100, a plurality of cable guides 41 may be provided on the top surface or edge of the pipe segment 100. Preferably, in this embodiment, the cable guide 41 is provided on the edge of the top surface of the pipe segment 100. It should be noted that, in other embodiments, the cable guide 41 may be arranged in other arrangements to achieve the purpose of reducing the contact probability between the longitudinal adjustment cable group 31 and the top surface of the pipe segment 100.
[0040] like Figure 3 and Figure 5 As shown, the lateral transfer support assembly 5 includes a plurality of support wheels 51, and the support wheels 51 are arranged on the edge of the top surface of the pipe segment 100. The transverse adjustment cable group 32 is wound around the support wheels 51 and connected to the anchor head group 1 to limit the movement of the transverse adjustment cable group 32 in the vertical direction, thereby reducing the contact area between the transverse adjustment cable group 32 and the top surface of the pipe segment 100, and reducing the probability of the sacrificial anode layer on the top surface of the pipe segment 100 being worn.
[0041] Preferably, the transverse transfer support assembly 5 includes a plurality of transfer wheels 52, the transverse adjustment cable group 32 is wound on the transfer wheels 52 and connected to the anchor head group 1, and the transfer wheels 52 can reduce the longitudinal force component of the transverse adjustment cable group 32, so that the transverse force component of the transverse adjustment cable group 32 is larger, thereby reducing the specifications of the winch group 2. Specifically, in this embodiment, the setting position of the transfer wheel 52 allows the transverse adjustment cable group 32 to be vertically wound during the process of winding the transfer wheel 52 to reduce the consumption of force components in other directions, and finally the transverse adjustment cable group 32 is led out in the transverse direction and wound on the support wheel 51, and finally connected to the anchor head group 1. The setting of the transfer wheel 52 reduces the longitudinal force component of the transverse adjustment cable group 32, so that the force applied by the winch group 2 to the transverse adjustment cable group 32 is applied to the anchor head group 1 as much as possible in the transverse direction.
[0042] like Figure 3 and Figure 4As shown, the mooring system for pipe segment sinking also includes a plurality of measuring control towers 6 , which are arranged on the pipe segment 100 at longitudinal intervals. The measuring control towers 6 are used to detect the sinking and floating status of the pipe segment 100 , and the winch group 2 is arranged on the measuring control towers 6 .
[0043] Specifically, the winch group 2 includes a longitudinal adjustment winch 21 and a transverse adjustment winch 22 , the longitudinal adjustment cable group 31 is connected to the longitudinal adjustment winch 21 , and the transverse adjustment cable group 32 is connected to the transverse adjustment winch 22 .
[0044] Preferably, the mooring system for pipe segment sinking further comprises a plurality of double-pan pulleys 7, and the longitudinal adjustment winch 21 is connected to the longitudinal adjustment cable group 31 via the double-pan pulleys 7. Further preferably, the diameter of the cable between the winch group 2 and the double-pan pulley 7 is larger than the diameter of the longitudinal adjustment cable group 31, and the winch group 2 adjusts the length of the cable and then pulls the longitudinal adjustment cable group 31 to adjust the distance of the pipe segment 100 in the longitudinal direction. Since the cable often rubs on the double-pan pulley 7, the diameter of the cable is larger than the diameter of the longitudinal adjustment cable group 31 to ensure the overall service life of the mooring system for pipe segment sinking.
[0045] Preferably, in this embodiment, the anchor head group 1 includes four anchor heads 11 arranged opposite to each other in both the transverse and longitudinal directions. Further preferably, there are two measurement control towers 6, each of which is provided with a longitudinal adjustment winch 21 and two transverse adjustment winches 22.

For ordinary technicians in this field, according to the concept of the present invention, there will be changes in the specific implementation methods and application scopes. The content of this specification should not be understood as limiting the present invention.
