A compression type permanent anchor is provided to reinforce the ground regardless of the formation of joints or holes on the ground and to let a wedge move normally without rotating in place and move normally and slipping by generating resistance to the pullout behavior of an anchor and enlarging fixing strength of an anchor blade against the ground. A compression type permanent anchor comprises an anchor head(10) inserted to the inside of an anchor hole and composed of a fixture fixed with the front of a tension member and a cap coupled to the fixture to be separable to protect the fixture, a guide block(20) connected to the rear of the anchor head and composed of a hollow(21) penetrated with a tension member and three first sliding surfaces to widen a wedge piece normally by tensing a tension member, not to rotate in place, one or more tension members(30) inserted to the inside of the guide block to make the front end fixed to the fixture of the anchor head via the guide block and the rear end exposed to the outside of the anchor hole to be connected to a tensioner(200), many wedge pieces(40) widened from the guide block along the guide block when the tension member is tensed and driven into the ground around the anchor hole and provided with second sliding surfaces to slide along the first sliding surfaces of the guide block, and a packer(50) installed to the rear end of the guide block and expanded by injecting milk, etc. to seal up the anchor hole tightly. |
