Embodiment Construction
[0093] like figure 1 A method for excavating a tunnel crossing a high-angle thrusting water-rich sand-rich fault is shown. The tunnel hole 1 of the constructed tunnel is divided into an upper hole body, a middle hole body 1-2, and a lower hole body 1-3 from top to bottom. , the upper hole is divided into a left pilot hole 1-11 and a right pilot hole 1-12 on the right side of the left pilot hole 1-11, see figure 2 and Figure 8 ;
[0094] like Figure 9 , Figure 10 and Figure 11 As shown, the primary support structure of the tunnel hole 1 is a double-layer primary support structure, and the double-layer primary support structure includes a concrete primary spraying layer 5- 2. Multi-pronged steel arch 5 supporting the tunnel hole 1 and standing on the inner side of the concrete primary spraying layer 5-2, and a concrete respraying layer formed by a layer of concrete sprayed on the concrete primary spraying layer 5-2 5-1. The tunnel hole 1 is supported by multiple struc...
