Description

Technical Field

[0001] The present invention relates to the technical field of immersed tube tunnels, and in particular to a mooring device. Background Art

[0002] During the construction of the immersed tube tunnel foundation, when multiple immersed tube sections are pulled together for installation, it is necessary to use cables to tie cable seats to gradually pull the immersed tube sections together to the designated installation position. When pulling together, the pulling force of the cables needs to overcome the friction between the bottom plate of the section and the foundation. At the same time, as the length of the immersed tube section increases, the volume of the structure also increases, which also leads to a greater pulling force required to pull the section together, that is, the mooring force increases accordingly, so the structural force of the cable seat also increases accordingly.

[0003] The existing cable seat is directly fixed to the pipe section to be pulled together by bolts. When the cable is tied to the cable seat and subjected to force, the bolts need to be subjected to shear force, tension, pull-out force and other forces at the same time. The performance requirements of the bolts are very high, that is, the number of bolts must be large, the diameter must be large, and the strength must be high, which increases the cost and construction difficulty.
