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

Embodiment Construction

[0042] like image 3 and Figure 4 As shown, in this embodiment, the butt joint pipes are the upper joint pipe 1b and the lower joint pipe 1a, and the docking device performs the docking operation between the upper joint pipe 1b and the lower joint pipe 1a, and the underwater docking device of the floating tunnel in water includes:

[0043] A cylindrical steel frame 2, such as figure 1 As shown, in order to prevent the marine environment from corroding the structure, all exposed surfaces of the steel frame 2 are coated with polyurethane anti-corrosion coating; the inner diameter of the steel frame 2 is 1-2 meters larger than the outer diameter of the pipe joint, and the axial length is 20-30 meters. Set its second half section on the outer circumference of the upper section pipe 1b, and use the roller 8 arranged on the second half section to support the outer circumference of the upper section pipe 1b; on the inner side wall of the first half section of the steel frame 2 1. ...

Abstract

The invention discloses an underwater butt connection device for submerged floating tunnels and application of the underwater butt connection device. The underwater butt connection device is characterized in that a cylindrical steel frame is arranged, and the rear half segment of the steel frame is arranged on an upper segment pipe in a sleeving and supported manner; surrounding steel rails and communicated axial steel rails are arranged at different axial positions on the inner side wall of the front half segment of the steel frame; a plurality telescopic mechanical arms are supported by the axial steel rails through rotatable rolling wheels and can move in the axial steel rails and the surrounding steel rails; a lower segment pipe is clamped through the telescopic mechanical arms arranged in pairs; the outer side wall of a butt joint pipe is provided with a temporary track in the axial direction; rollers are supported in the temporary track; and the butt joint pipe and the steel frame are coaxial and can move relatively in the axial direction. Accurate butt joint of the submerged floating tunnels is achieved in a semi-automatic manner.

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...
