The invention provides a tunnel construction method. The tunnel construction method is applied to the construction of an underground tunnel passing through a station. The tunnel construction method includes: grouting and strengthening the roadbed located above the preset tunnel route; The upper rail is buckled for reinforcement construction; a working well is dug at the starting position and the ending position of the preset tunnel route. The working well at the starting position is used as the starting well, and the working well at the ending position is used as the starting well. As a receiving well; the pipe shed structure construction is carried out above the preset tunnel; the pipe curtain structure construction is carried out below the pipe shed, and the main body of the open-cut and buried section at both ends of the preset tunnel is constructed at the same time; the tunnel is excavated with earthwork , until the entire tunnel is penetrated. The tunnel construction method of the present invention solves the problem that the tunnel construction in the prior art easily causes damage to ground facilities.
Description
technical field [0001] The invention relates to the technical field of tunnel construction, in particular to a tunnel construction method. Background technique [0002] During the construction process and after the completion of the traditional tunnel, the subgrade settlement accuracy of the above-ground construction is not very high. With the expansion of railways and highways, some tunnels are constructed above the existing buildings. Once the tunnel below is excavated, it is inevitable It will cause a certain degree of settlement, and the longer the time, the more obvious the settlement will be. It will cause damage to the building above the tunnel construction, or even collapse, which is very dangerous. [0003] For example, an existing railway station is located in the center of the city, and there is traffic congestion on the road. It is urgent to open new roads to disperse the traffic flow. A certain municipality plans to build two underground lanes to pass through th...
