Problems solved by technology

The joint structure is a flexible joint, which is applied to immersed tunnels. The existing tunnel joints represented by this patent are basically applied to immersed tunnels, which cannot be applied to underwater floating tunnels, and cannot meet the requirements of underwater tunnel stress, sealing and Anti-corrosion requirements, etc.

Embodiment Construction

[0040] Such as figure 1 As shown, the floating tunnel in the water is located below the water surface 10, and the tension leg 11 is connected under the tunnel. The tension leg 11 is anchored at the bottom of the water area through the anchor structure 12, and the road surface 13 is laid in the tunnel for vehicles and pedestrians to pass through. The tunnel is formed by the butt joint of several coaxial pipe sections, and the butt joint between two adjacent pipe sections is called the joint.

[0041] Taking the joint structure of the adjacent left and right pipe sections 1 and 2 as an example, the joint structure of the floating tunnel in water according to the present invention will be described. figure 2A partial axial sectional view of the joints of the left and right pipe sections 1 and 2 is shown. The left and right pipe sections 1 and 2 are coaxial and have the same inner and outer diameters. The right end of the left pipe section 1 is a tapered sleeve 101 with a tapere...

Abstract

The invention discloses a water suspension tunnel connector. The water suspension tunnel connector comprises two pipe sections in butt joint. Connector space is formed between the two pipe sections. The two pipe sections are connected through a damping structure and a sealing structure. The damping structure comprises a connecting sleeve arranged outside the two adjacent pipe sections in a sleeving manner, radial prestress inhaul cables connecting the two ends of the connecting sleeve with the two pipe sections, axial prestress inhaul cables located in the two pipe sections and coaxially arranged, and a tensioning device located between the two pipe sections and used for pulling the coaxial axial prestress inhaul cables. Compared with a traditional immersed tunnel connector, the water suspension tunnel connector is provided with the axial prestress inhaul cables and the radial prestress inhaul cables, vibration and deformation generated by the water suspension tunnel connector in the complex ocean environment can be avoided, and it is guaranteed that a GINA rubber water stop band cannot leak due to dislocation.

Description

technical field [0001] The invention is a submerged floating tunnel joint. Background technique [0002] The underwater floating tunnel, also known as the Archimedes bridge, uses buoyancy to support the tunnel body and the weight of traffic loads, and is a new way of transportation across water. Because there are still many problems to be solved urgently, a practical floating tunnel in water has not yet been built in the world. However, the characteristics of economy, environmental protection, convenience and earthquake resistance of the floating tunnel in water are destined to have a very broad application prospect. [0003] Pipe joints are a critical link in floating tunnels and indeed in all underwater structures. At present, the design of underwater tunnel joints at home and abroad is mainly aimed at immersed tube tunnels, shield tunnels, etc., and there is no specially designed floating tunnel joint structure. The pipe joints of immersed tunnels include intermediate ...
