Tunnels are engineering structures buried in the ground and are a form of human use of underground space. The tunnel can be divided into a traffic tunnel, a hydraulic tunnel, a municipal tunnel and a mine tunnel. In 1970, the international economic cooperation and development organization held a tunnel conference which integrates various factors, and the definition of the tunnel is as follows: "a cavity with a cross section area larger than 2 square meters is built under the ground by any method according to a specified shape and size in a certain application. "

The stability of the surrounding rock of the tunnel is a very important problem in the tunneling process, and particularly the stability of the surrounding rock in a fault fracture zone section needs to be paid attention. The construction method of the existing tunnel in the fault fracture zone section comprises the following steps: drilling holes in the broken loose rock mass in advance, driving a small guide pipe into the holes, pressing and injecting grout with gelling property, quickly permeating the grout into the broken loose rock mass in a vein shape under the action of grouting pressure, discharging air and water in the grout, and cementing and gelling the broken loose rock mass to form a consolidated body which has certain strength, impermeability and water resistance and takes the grout as a framework, so that the integrity, impermeability and stability of the surrounding rock are improved; the leading small pipe shed and the consolidation body form a shell with certain strength, and excavation supporting construction is carried out under the protection of the shell. In the construction process, because surrounding rocks in fault fracture zones are broken and weak, underground water is abundant, and the surrounding rocks are soaked for a long time, collapse or instability of the surrounding rocks and supports is easily caused. In order to realize drainage, a small guide pipe is used for grouting and water plugging, a drilled drainage hole is enriched in bottom water, and the small guide pipe is arranged; and a drainage ditch is arranged at the side wall, and water in the vault and the side wall is led to the drainage ditch.
