SOIL NAILING METHOD AND THE GROUND REINFORCEMENT STRUCTURE USED SOIL NAILING

摘要

A soil nailing method is provided to make the lower nail in which the shear stress is focused upon, more stable and to reduce the length of the perforation hole. A soil nailing method includes following steps: a step which an upper perforation hole in the ground is formed beyond a lower perforation hole; a step which an upper nail(300a) is inserted into the upper perforation hole and a lower nail(300b) is inserted into the lower perforation hole. The upper nail is formed shorter than the lower nail.
