PURPOSE: A pressing water stopping type anchoring method is provided to apply the high anchoring force in the excavated ground in which the groundwater level is high. CONSTITUTION: A pressing water stopping type anchoring method is composed of the steps of forming a perforated hole by boring an underground excavation ground, inserting an anchor body into the perforated hole, grouting the inside of the perforated hole by injecting grout material through a grouting hose(20), pulling the grouting hose, expanding a limit expansion packer(100) by injecting the air through an air injection hose(30), and hardening the injected grout material. The limit expansion packer includes a rubber tube(110), a packing member(120), a fiber fabric(130), and a steel band(140). The rubber tube is formed in a cylindrical shape whose front and rear ends are opened. The packing member is inserted in the front and rear ends of the rubber tube. The anchor body includes an inner body, a steel strand(10), an air injection hose, and a grouting hose. |
