The present invention relates to a technology to inject a grouting material effectively when grouting an anchor for ground reinforcement and, more specifically, to a technology related to an anchor grouting method for ground reinforcement capable of preventing a packer from being pushed backward when injecting a thick grouting material by penetrating a protrusion unit formed on the lateral part of the packer into an inner wall of an insertion hole when inserting the reinforcing anchor connected to the packer into the insertion hole on the ground and injecting the thick grouting material and stroking a second packer to an insertion pipe, which is inserted into the insertion hole with the reinforcing anchor, in a vertical direction when injecting a thin grouting material to the second packer, which is inserted inside the injection pipe, through the injection pipe. According to the present invention, the reinforcing anchor and the injection pipe, which are inserted into the insertion hole, becomes hardened to be firmly integrated with the ground adjacent to the insertion hole at high density is obtained. |
