Embodiment 1

[0038] Embodiment one, such as Figure 1 to Figure 8 As shown, the present invention proposes an underwater anti-arch suspension double tunnel that utilizes steel cables for positioning, including anchor spindle and driving well 1 and anchor spindle and receiving well 2, and anchor spindle and driving well 1 and anchor spindle and receiving well 2 Between the well 2 are provided with the first steel cable 53, the second steel cable 54, the third steel cable 55, the first tunnel 3 with a circular section congruent or a polygonal cross section with two mutually perpendicular symmetry axes, vertical and horizontal, and Second Tunnel 4.

[0039] The first steel cable 53 is located directly below the first tunnel 3, the second steel cable 54 is located directly below the second tunnel 4, the third steel cable 55 is located between the first tunnel 3 and the second tunnel 4, and the first steel cable 53 1. The second steel cable 54 and the third steel cable 55 are arranged in a cha...

Embodiment 2

[0049] Embodiment 2, a method for constructing an underwater anti-arch floating double tunnel positioned by steel cables, comprising the following steps:

[0050] S1. The numbers of the first pipe sections of the prefabricated M section are 3-1, 3-2, ..., 3-M, and the numbers of the second pipe sections of the M section are 4-1, 4-2, ..., 4-M, The central axis of each first pipe section 3-1, 3-2, ..., 3-M or second pipe section 4-1, 4-2, ..., 4-M is a straight line, and the cross section is circular or vertical A polygon with two mutually perpendicular symmetry axes, straight and horizontal. The side view is an isosceles trapezoid whose upper side is shorter than the lower. The segment length is not less than 2m and not more than 30m, and the angle between the extension lines of the two sides of the isosceles trapezoid in side view is not more than 5°. And on both sides of the water area to be crossed, an anchor spindle and a driving well 1 and an anchor spindle and a receivi...

Abstract

The invention discloses an underwater anti-arch floating double tunnel positioned by steel cables and a construction method thereof. The key points of the technical scheme are: an underwater anti-arch suspended double tunnel positioned by steel cables, including an anchor and a drive The well and the anchor and receiving shaft are provided with a first steel cable, a second steel cable, a third steel cable, a first tunnel and a second tunnel between the anchor and driving shaft and the anchor and receiving shaft; the first tunnel Divided into several sections of the first pipe section, the second tunnel is divided into several sections of the second pipe section, each first pipe section is provided with several first lower connecting rings for the first steel cable to pass through; the second pipe section is provided with several The second lower connection ring is used for the second steel cable to pass through; two first side connection rings are provided at the two ends of the first pipe section near the second pipe section, and two first side connection rings are provided at the two ends of the second pipe section near the first pipe section. The second side connecting ring, the first side connecting ring and the second side connecting ring are used for passing the third steel cable. 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 double 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 constr...
