Roadbed subsidence repairing device and method
The invention belongs to the technical field of roadbed repair, and discloses a roadbed subsidence repairing device and method. The repairing device comprises a steel arch, mini piles, a concrete abutment body, a steel shim, filled concrete and grouting pipes. The load of a roadbed subsidence section can be transmitted to a non-subsidence roadbed area with larger strength, the non-subsidence roadbed area surrounds the roadbed subsidence section, and the non-subsidence roadbed area does not subside; a certain compaction function to a weak roadbed can be achieved through high-pressure grouting, the deformation resistance of the roadbed is improved through filling of gaps and cracks of the surface layer of the weak roadbed, and the further subsidence of the weak roadbed can be effectively controlled. Meanwhile, the situation that surface rainfall is immersed in a roadbed channel is interdicted through filling of the concrete and the grouting body, and the roadbed is prevented from being immersed in water, softened and disengaged again. The roadbed subsidence repairing device and method have the advantages that the subsidence treatment of the roadbed is achieved, the technology is simple, the quality can be controlled, the construction progress is fast, the roadbed subsidence problem caused by reduction of the strength of the roadbed is basically eliminated, and the service life of the highway road surface structure is prolonged.
