An underwater docking device for a floating tunnel in water and its application

Abstract

An underwater docking assembly for underwater suspension tunnels and an implementation method therefor. The docking assembly comprises a steel frame (2). The second half section of the steel frame (2) is sleeved and supported on an upper tube (1). A plurality of surrounding steel rails (7) is disposed at different axial positions on the inner side wall of the first half section of the steel frame (2), axial steel rails (6) communicating the surrounding steel rails (7). A plurality of telescopic mechanical arms (5) is supported on the axial steel rails (6) by means of rotatable idler wheels (51), and can move in the axial steel rails (6) and the surrounding steel rails (7). The paired telescopic mechanical arms (5) clamp a lower tube (1'). Temporary tracks (3) are disposed on the outer side wall of a docking tube axially, and rollers (8) are supported in the temporary tracks, such that the docking tube and the steel frame (2) are located at a coaxial position and can relatively and axially move. The docking assembly and the corresponding docking method can achieve accurate docking of underwater suspension tunnels in a semi-automated form.

Description

technical field [0001] The invention relates to an underwater tunnel docking device, in particular to an underwater floating tunnel underwater docking installation device and its application. Background technique [0002] The floating tunnel in the water, also known as the Archimedes bridge, maintains the balance and stability in the water through the joint action of the structure's self-weight, buoyancy and anchoring system. Compared with traditional transportation forms such as sea-crossing bridges and immersed tube tunnels, floating tunnels in water are a new type of transportation concept proposed in recent years. Due to its own economy, environmental protection, earthquake resistance and convenience, it is destined that the underwater floating tunnel will have a very broad application prospect in the future. However, the transportation concept of floating tunnel in water involves a wide range of fields, and there are still many technical problems to be solved. Therefor...

AI Technical Summary

Problems solved by technology

Unlike immersed tube tunnels, underwater floating tunnels are usually located between ten and thirty meters underwater. In addition to the factors affected by the underwater butt joint installation of immersed tube tunnels, water flow and waves will cause the floating tunnel body and the installation and lifting ship to swing , which greatly increases the difficulty of docking the floating tunnel body in water
