GROUND ADHERING SOIL NAILING STRUCTURE AND GROUND REINFORCEMENT METHOD USING THE SAME

摘要

A ground adhering soil nailing structure and a ground reinforcement method using the same are provided to increase the valid diameter and the shear resistance of anchorage by the pressure grouting. A ground adhering soil nailing structure includes an inner groove in which the steel reinforcement rib of nail(2) is fixedly inserted in the inner circumference; a pair of nail truss bolts including the cork in the outer circumference of the semi-cylindrical shape; a female thread which surrounds the outer circumference of the nail truss bolt of the pair; a settlement packer which is expanded by injecting the grout material into the outer circumference(13); an anchorage(10) consisting of the nail settlement nut(12) and a settlement anchor(14); a stationary tube including the hollow inside; a pressure grouting packer surrounding the outer circumference of the stationary tube; an anchor plate fixed by a fixing nut(5).
