GROUND REINFORCEMENT METHOD APPLIYING PRESTRESS

摘要

A ground reinforcing method through prestress is provided to reinforce the sheer stress of the ground through the prestress by applying the prestress extending the PC steel wires. A ground reinforcing method through prestress is composed of a step of forming an insertion hole on the ground; a step of injecting the reinforcement in the insertion hole; a step of cleaning the vicinity of the insertion hole and installing the pressure member in the inlet of the insertion hole; a step of extending the PC steel wires of the reinforcement; a step of injecting the cement milk in the inserting hole for grouting through the injection hose of the reinforcement; and a step of installing the finishing cap at the pressure member and cleaning the vicinity of the insertion hole. The cement milk is pressure-injected, and the pressure valve is mounted at the pressure member.
