PROBLEM TO BE SOLVED: To provide the superior natural ground reinforcing effect by uniformly injecting a consolidation material into the periphery of a reinforcing pipe in a natural ground reinforcing construction method such as preceding tunneling work and work face part reinforcing work, particularly, a natural ground reinforcing construction method for injecting and solidifying the consolidation material in the reinforcing pipe driven in the natural ground and the surrounding natural ground.
SOLUTION: This natural ground reinforcing construction method forms a consolidation area in the natural ground by permeating the consolidation material in the reinforcing pipe and the surrounding natural ground by injecting the consolidation material into the reinforcing pipe by driving the reinforcing pipe having a delivery hole in a peripheral surface and having the prescribed length in the natural ground, and is characterized by injecting the consolidation material into the reinforcing pipe while transmitting vibration to the consolidation material or the reinforcing pipe or both when injecting the consolidation material into the reinforcing pipe.
