Abstract

The invention relates to a seabed submerged floating tunnel structure, and belongs to the technical field of tunnels. The seabed submerged floating tunnel structure comprises a tunnel body, the tunnel body comprises a tunnel main body section, two first tunnel branch sections and two second tunnel branch sections, wherein the two first tunnel branch sections and the two second tunnel branch sections are symmetrically arranged on the two sides of the tunnel main body section correspondingly; the two first tunnel branch sections and the two second tunnel branch sections communicate with the interior of the tunnel main body section; and a bearing mechanism located right below a portal is arranged at one end of the tunnel main body section. The invention further discloses a construction method. The seabed submerged floating tunnel structure and the construction method thereof have the advantages that the structure design is reasonable, in addition, the butt joint mode is simple and effective, tunnel butt joint is realized in a pouring connection mode, the stability of tunnel butt joint is improved, the functions of seabed observation and sealing performance test are added in the construction process, in this way, seabed construction is easy to operate, the accuracy and efficiency of tunnel butt joint are improved, in addition, a very safe construction environment is provided, meanwhile, an escape emergency channel is designed in a whole tunnel, and the overall safety performance of the tunnel is improved.

Description

technical field [0001] The invention belongs to the technical field of tunnels, and relates to a submarine underwater suspension tunnel structure and a construction method thereof. Background technique [0002] The floating tunnel, also known as the Archimedes bridge, is a circular or oval pipe structure that is suspended under several floating bodies (pontoon boats) to form a passable underwater tunnel. In order to avoid affecting water traffic and being affected by the weather, the tunnel is built on the bottom of the water, but in order to avoid excessive water pressure, it is often built at a depth of 20-50 meters, and it is also convenient for large-tonnage ships to pass. In order to maintain the depth in the water, the tunnel is fixed with steel cables and floating platforms to prevent it from being too shallow or too deep. The cross-section of the underwater floating tunnel can be elliptical or circular, with a length of several kilometers and a width of tens of mete...
