SOIL NAILING METHOD USING OPPRESSED GROUTING AND DEVICE THEREOF

摘要

PURPOSE: The soil nailing method is provided to improve the stability of the structure of soil nailing due to enabling dense packing in vulnerable part and also enabling hardening function by the pressure of grouting ground. CONSTITUTION: The soil nailing method comprises the steps of: performing the drilling hole of a specific diameter through a drilling device at a specific position of the ground; establishing the reinforcing material of a pipe having the interval material in a specific interval on the outer circumference integrally established on the drilled hole; densely sealing the drilled hole by firmly establishing a packing member between the front end of the drilled hole and the outer circumference of the reinforcing material; grouting so the inside of the drilled hole as to be densely packed by spraying high-pressure cement milk supplied through the spraying hole of the pipe reinforcing material; establishing concrete toward the wall body of corresponding ground.
