REINFORCEMENT MATERIAL AND DEVELOPMENT METHOD THEREOF

摘要

PROBLEM TO BE SOLVED: To provide a method of developing a reinforcement material, configured to increase bearing resistance against removal by reliably injecting an injection material around reinforcement materials, in reinforcing relatively small-scale slope ground against landslide. ! SOLUTION: A reinforcement material development method includes the steps of: arranging a filling pipe 40 in a hole 111 filled with an injection material; arranging filling packers 50-52 in the filling pipe 40; pressure-supplying the injection material through the injection packers 50-52, and discharging the injection material into a ground 100 through one discharge hole 47 of the filling pipe 40; moving the injection packers 50-52 along a longitudinal direction, pressure-injecting the injection material through the injection packers 50-52, and discharging the injection material into the ground through the other discharge holes 47 of the filling pipe 40; and removing the injection packers 50-52 and filling the filling pipe
