Abstract

The invention discloses an underwater inverted-camber-shaped suspension tunnel utilizing a steel cable for positioning and a construction method of the underwater inverted-camber-shaped suspension tunnel. According to the key points of the technical scheme, the underwater inverted-camber-shaped suspension tunnel utilizing the steel cable for positioning comprises an anchoring and driving well and an anchoring and receiving well, and the steel cable and a tunnel body are arranged between the anchoring and driving well and the anchoring and receiving well; and the tunnel body is divided into a plurality of sections of pipe joints, and each pipe joint is provided with a plurality of connecting rings to allow the steel cable to penetrate. According to the underwater inverted-camber-shaped suspension tunnel utilizing the steel cable for positioning and the construction method of the underwater inverted-camber-shaped suspension tunnel, precise positioning and constructing of the underground suspension tunnel in rivers, lakes and seas are facilitated.

Description

technical field [0001] The invention relates to the field of underwater floating tunnels, in particular to an underwater anti-arch floating tunnel positioned by steel cables and a construction method. Background technique [0002] The floating tunnel, also known as the Archimedes Bridge, is a new type of cross-water traffic structure. It mainly uses the buoyancy of the tunnel body to balance gravity and operational traffic loads. Since the floating tunnel system was proposed in the 1950s, it has attracted the attention of countries such as Denmark, Italy, Norway, Japan, the United States and China. With the continuous research and promotion of scientific researchers, its concept can be widely disseminated and accepted by people. However, due to its complex environment and unknown structural performance, there are no suspended tunnel structures successfully built in the world. [0003] During the construction process of the floating tunnel, it is easily affected by environ...
