Problems solved by technology

[0002] There are mainly two methods for subsea tunnel construction in the prior art. One is to excavate the tunnel under the seabed by a shield machine. This method is very difficult to prevent water leakage from entering the tunnel and repair the shield machine. The tubes are assembled on the bottom of the sea. The quality of the immersed tubes in this method is too large, which makes the construction difficult. For example, the quality of the immersed tubes in the tunnel section of the Hong Kong-Zhuhai-Macao Bridge is as high as 74,000 tons. Installing such a heavy immersed tube requires a lot of manpower, material and financial resources and dozens of patented technologies to complete the installation; in order to overcome the above shortcomings, the present invention discloses a subsea tunnel construction process that is extremely simple in construction, light in weight, high in rigidity, and low in construction cost

Embodiment Construction

[0022] According to the accompanying drawings, a simple construction method of an undersea tunnel is described:

[0023] figure 1 As shown, a section of immersed tube 1 is combined into a whole by two circular tubes with the same length, diameter and shape, and the diameter 4 of the circular tube is 10 to 11.4 meters. figure 2 As shown, the thickness 5 of the tube wall is 0.8 to 1 meter, and the tube wall is an empty stomach structure, and the empty stomach space of the tube wall is called the tube wall empty stomach 6; because the tube wall is an empty stomach shape, the shape of the immersed tube is designed to be a circular tube shape In order to resist the water pressure of the seabed, the shape of the round pipe has a strong ability to resist water pressure after pouring concrete, so the thickness 5 of the pipe wall can be designed to be 0.8 to 1 meter; the manufacturing material of the round pipe is glass fiber reinforced plastic (GFRP), the material strength is equiva...

Abstract

The invention discloses an easy construction method of a subsea tunnel, and aims to solve the technical problem of great construction difficulty in subsea tunnel construction. The technical scheme ofthe invention is that an immersed tube is of a whole body which is formed by two circular tubes with the same length, diameter and shape; a trapezoidal male tenon is arranged at one end of each circular tube, and a trapezoidal female tenon is arranged at the other end of each circular tube; and when the circular tubes are butted, the male tenon is clamped into the female tenon, so that immersed tubes are connected integrally.
