[0029] In order to clearly illustrate the technical features of this solution, the specific implementation of the present invention will be further described below based on the drawings.
[0030] A method for installing an underground arched roof includes the following steps:
[0031] a: Set up a pipe shed 5 in the soil for advanced support (such as figure 1 , figure 2 As shown), and then drill a groove 2 under the pipe shed 5 to the design depth (such as image 3 , Figure 4 Shown);
[0032] b: Insert the two longitudinal beams 6 into the groove 2 so that the two longitudinal beams 6 are overlapped on the concrete precast piles 3 on both sides of the tunnel. The concrete precast piles 3 are provided with corbels 4, and the longitudinal beams Beam 6 overlapped on the corbel 4 (such as Figure 5 , Image 6 Shown);
[0033] c: Insert the prefabricated arched top plates 1 into the grooves 2 one by one, so that the two sides of the prefabricated arched top plate 1 are overlapped on the l...
