COMPRESSION TYPE SOIL NAILING APPARATUS AND METHOD

摘要

PURPOSE: A pressure-type soil nailing apparatus and method are provided to minimize the volume of a packer member by simplifying the structure of the packer member connected to a soil nail. CONSTITUTION: A pressure-type soil nailing apparatus(1) comprises a soil nail(10), a packer member(20), a grouting hose(30), an air exhaust hose(40), and a fastening member. The soil nail is inserted into a borehole(100) of the ground. The packer member is connected to the soil nail. The grouting hose penetrates through the packer member and supplies a filling material to the inside the borehole. The air exhaust hose penetrates through the packer member and exhausts air and water from the borehole to the outside when the filling material is supplied. The fastening member is coupled to the soil nail and inserts the packer member and the soil nail into the borehole.
