SOIL-NAILING METHOD FOR ELIMINATION OF TENSION MEMBER USING MANUAL TENSION DEVICE AND FIXING UNIT

摘要

PURPOSE: A removal type soil nailing method using a hand-operated tensioning device and a fixation unit is provided to stably fix a tensile member inside an excavation hole with simple structure. CONSTITUTION: A removal type soil nailing method using a hand-operated tensioning device and a fixation unit comprises following steps. An excavation hole(H) is punched in the ground. A fixation unit is assembled on one end of a tensile member(10). The tensile member is inserted into the excavation hole so that the fixation unit can be mounted inside the excavation hole. The grout material(13) is injected into the excavation hole and is cured. The hand-operated tensioning device is assembled with the other end of the tensile member. The hand-operated tensioning device stretches the tensile member. The hand-operated tensioning device removes the tensile member.
