Problems solved by technology
[0004] The above-mentioned existing technical solutions have the following defects: the joint devices of the floating tunnel are all "point-to-point" docking of two adjacent pipe bodies, the length of the butt joint of adjacent pipe bodies is relatively short, and they are all in the form of a single pipe, and the structural integrity and The connection strength is poor, and it is difficult to meet the design requirements of "the stiffness of the joint must not be lower than the stiffness of the pipe itself", and there are major safety risks

Embodiment 1
[0053] figure 1 It is a structural schematic diagram of the floating tunnel joint device 1 in the present invention, as figure 1 A pipe body joint device for a double-pipe floating tunnel shown includes a joint device 1, a tunnel pipe body 2, an escape device 3 and an anchor ring 4, wherein the joint device 1 is used to fix the adjacent tunnel pipe bodies 2 head to tail Connected together, the tunnel body 2 is a pipe section of the suspended tunnel body 2 close to the joint device 1, which is a double-pipe or multi-pipe structure;
[0054] Two escape devices 3 are fixedly connected to the middle area inside the joint device 1 for the rapid evacuation of personnel in an emergency; a plurality of anchor rope rings 4 are fixedly connected to the outside of the joint device 1 for the anchor of the floating tunnel For the installation of cable 6, all the above structures are submerged at a depth of 30-50 meters below the sea surface;
[0055] Preferably, the length of the single-...

The present invention relates to the field of underwater tunnel traffic infrastructure equipment, in particular to a double-pipe floating tunnel body joint device and method, including a joint device, a tunnel body and an escape device, the escape device is arranged inside the joint device, and the tunnel body is respectively Connected to the left and right ends of the joint device, there are multiple anchor rope rings connected to the outside of the joint device. The joint device includes a watertight locking structure section, a skeleton connection section and a main functional section. The main functional section includes the inner road surface of the joint and the joint The outer casing and the inner road surface of the joint are arranged inside the outer casing of the joint, and the watertight locking structure sections are respectively connected to the two ends of the skeleton connection section. Compared with the traditional floating tunnel joint device, the present invention can only satisfy a single function, improves the utilization rate of the inner space of the underwater floating tunnel, greatly reduces the complexity of the overall linear structure system of the floating tunnel, and improves the integrity of the tunnel joint, pipe The connection strength between the body and the joint reduces the safety risk of the tunnel.
Description
technical field [0001] The invention relates to the field of underwater tunnel traffic infrastructure equipment, in particular to a pipe body joint device and construction method for a double-pipe floating tunnel. Background technique [0002] The floating tunnel is a large-scale cross-sea traffic structure suspended in the water. It is another subversive transportation technology for human beings to realize the crossing of deep-sea fjords in the future after cross-sea bridges and submarine tunnels. Compared with the traditional ultra-deep water large-scale sea-crossing channel, the floating tunnel can theoretically be built in any water area with long span, large water depth, and steep bed. It mainly solves the problem of crossing traffic in wide waters and deep water fjords, and has huge engineering applications In recent years, it has received great attention from academic circles and engineering circles at home and abroad. This new type of transportation was proposed in...
