Description
Technical Field
The invention relates to the technical field of tunnel construction support systems, in particular to an auxiliary system and a construction method thereof suitable for rapid construction of a tunnel advance small guide pipe.
Background
In tunnel construction, when tunneling is carried out to a surrounding rock section with poor integrity and stability, in order to inhibit surrounding rock deformation and ensure the safety of tunnel excavation construction, an advanced grouting small conduit is additionally arranged in a certain range of the tunnel to inhibit surrounding rock deformation, and broken rock bodies in a certain range in front of the tunnel are concreted through grouting of the small conduit in the construction process, so that the integrity of the surrounding rock is ensured, and then the falling blocks and collapse of the surrounding rock at the vault part of the tunnel are reduced.
However, in the construction process of the tunnel advance small guide pipe at present, the support work of the advance small guide pipe still needs to be finished manually, but because the manual operation process is slower and the manual operation error is higher, the annular space, the external insertion angle, the depth of the embedded rock mass and other parameters of the small guide pipe cannot be finished rapidly and acceptably, so that the construction period is delayed, and more serious, the reinforcement effect of the advance grouting small guide pipe on surrounding rock in front of the tunnel cannot reach the expected target, and great potential safety hazards are buried for the subsequent safety construction of the tunnel; in case of poor geologic bodies with complex geologic hydrologic conditions and extremely poor surrounding rock self-stability, the working efficiency and the method can not ensure the integrity and the stability of the surrounding rock of the tunnel, and finally, the safety accidents such as the blocking and collapse of the arch part of the tunnel can be frequently caused. The stress redistribution of surrounding rock at the arch part of the tunnel caused by the fact that the advanced grouting small guide pipe is not standardized and not in place brings great safety risks and load uncertainty to the supporting structure. Tunnel construction safety accidents which are caused by continuous large deformation of the structure under the action of uncertain huge surrounding rock pressure and are finally destroyed are frequent, so that extremely bad social influence and huge economic loss are caused.
Therefore, it is needed to design an auxiliary system suitable for rapid construction of the tunnel advance small guide pipe, so as to solve the problem of construction quality of the tunnel advance grouting small guide pipe, ensure the integrity and stability of surrounding rock and realize rapid and standard support.
