Problems solved by technology

[0005] However, the tunnel construction of the existing immersed tube method is convenient. After all the prefabricated components of the tunnel are sunk into the seabed and connected, then the water in the tunnel is completely discharged through the drainpipe, and finally enters the tunnel to carry out the internal construction of the tunnel. Difficult and inefficient

Embodiment Construction

[0031] Embodiments of the present invention will be further described below in conjunction with the accompanying drawings:

[0032] like figure 1 and figure 2 As shown, a tunnel prefab 1 includes a tunnel body 11 in an arched structure, and a plurality of horizontally arranged drainage pipes 12 and vertically arranged connecting piles 13 are preset on the base of the tunnel body 11. The tunnel body 11 A floating ring 14 is provided at the front and rear ends of the sealing ring 14, a sealing ring 15 is formed at the end of the floating ring 14, an outer connecting ring 16 is provided on the outer ring of the sealing ring 15, and an inner connecting ring is provided on the inner ring of the sealing ring 15 17. Several bolt holes are formed on the outer connecting ring 16 and the inner connecting ring 17. Both ends of the tunnel body 11 are also provided with sealing walls 18 for sealing the tunnel body 11. The sealing walls 18 are connected to the tunnel. The main body 11 is...

Abstract

The invention discloses a construction method for a subsea tunnel. The construction method is characterized in that several horizontally arranged water draining pipelines and a vertically arranged connecting column are preinstalled on a base of a tunnel body, floating rings are arranged at the front and back ends of the tunnel body, and sealing rings are formed on the end portions of the floatingrings; outer connecting rings are annularly arranged on the outer portions of the sealing rings, inner connecting rings are arranged annularly in the sealing rings, and several uniformly distributed bolt holes are formed in the outer connecting ring and the inner connecting ring; sealing walls used for sealing the tunnel body are further arranged at the two ends of the tunnel body and are detachably connected with the tunnel body. The construction method has the advantages that under the sealing effect of the sealing wall, in the process of laying the tunnel, in order to avoid that sea water is poured into the tunnel, when each tunnel prefabricated piece is laid, construction for the inside of the tunnel can be directly conducted in the tunnel, laying and construction are conducted synchronously, parts of the tunnel can also be pre-arranged in advance and then subjected to sinking laying, and the work efficiency of construction is greatly improved.

Description

technical field [0001] The invention relates to the field of submarine tunnel engineering, in particular to a method for constructing a submarine tunnel. Background technique [0002] The submarine tunnel is a marine structure built under the seabed for people and vehicles to pass under the condition of solving the traffic across the straits and bays without hindering the navigation of ships. [0003] At present, the construction methods of submarine tunnels usually include four methods: drill and blast method, immersed tube method, roadheader method, and shield method. [0004] Among them, the tunnel construction method of the immersed tube method is to float the prefabricated tunnel prefabricated components to the sea surface (river surface) site, and then sink and install them one by one in the dredged foundation groove. In Hong Kong, a number of subsea tunnels are constructed using the immersed tube method. [0005] However, the existing immersed tube method is conveni...
