GROUND REINFORCEMENT METHOD AND DEVICE THEREOF

摘要

A ground reinforcing method and a ground reinforcement used at the same are provided to increase support stress of the reinforcement and reduce the number of insertion holes by installing the different shaped reinforcing bars and PC steel wires. A ground reinforcing method is composed of a step of forming an insertion hole on the ground; a step of inserting a reinforcement assembled with PC steel wires whose one end is fixed; a first grouting step of injecting the cement milk through the injection hose and grouting the inserting hole; a step of mounting the pressure member at the inlet of the insertion hole; a step of extending and fixing the PC steel wires of the reinforcement; a step of inserting the different shaped reinforcing bars in the injection pipe; a second grouting step of pressure-injecting the cement milk in the injection pipe to allow the cement milk to grout the injection pipe; and a step of installing the finishing cap at the pressure member and cleaning the vicinity of the insertion hole. Corrugated pipes are formed to increase the friction resistance with the secondly grouted cement milk.
