様、クサビ保護管３、をセットする。DISCLOSURE OF THE INVENTION According to the present invention, a wedge protection tube is provided in which a wedge having a structure that can be inserted is mounted behind a bit at the tip, and the wedge is kept immediately after the bit until a predetermined excavation length is reached. Set 3.

打撃を加え、割り入れクサビ２、を開かせる。Operation: Set the cutting wedge 2 and the wedge protection tube 3 in the anchor body and proceed to dig to a predetermined depth. When the predetermined depth is reached, pull out the wedge protection tube 3 and insert the cutting tube 7. Then, when the wedges are hit, the cutting pipe 7 is hit to open the cutting wedges 2.

【発明の効果】アンカ−の支持基盤が軟弱な場合、固定
剤の注入だけでは十分な支持が得られない。クサビを割
り入れる事により、先端部が掘削孔より大きくなるた
め、引き抜きに対する抵抗が非常に大きいものとなる。When the support base of the anchor is soft, sufficient support cannot be obtained only by injecting the fixative. By cutting the wedge, the tip becomes larger than the drilled hole, and the resistance against pulling out becomes very large.
