Abstract

The invention discloses an underwater anti-arch suspension tunnel positioned by steel cables and a construction method thereof. The key points of the technical scheme are: an underwater anti-arch suspension tunnel positioned by steel cables, which includes an anchor and driving well and Anchor and receiving shaft, steel cables and tunnels are installed between the spindle and driving shaft and the anchor and receiving shaft; the tunnel is divided into several sections of pipe joints, and each pipe joint is provided with several connecting rings for the steel cables to pass through. The invention is convenient for precise positioning and construction of underwater suspension tunnels in rivers, lakes and seas.

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. With the continuous research and promotion of scientific researchers, its concept can be widely disseminated and accepted by people. However, due to reasons such as its complex environment and unknown structural performance, there is no suspended tunnel structure successfully built in the world. [0003] During the construction process of the floating tunnel, it is easily affected by environmental factors such as water flow, resulting in deviations in the construction and installation of the floating tunnel, which affects the precise construction ...
