Summary:PURPOSE: A multi-compression pressure-dispersed permanent anchor is provided to maximize friction in the ground difficult to secure a tensile force by easily compressing the peripheral ground. CONSTITUTION: A multi-compression pressure-dispersed permanent anchor comprises a strand which is inserted in an excavated hole(10), a load-carrying element(160) with a locking protrusion and a locking groove, packers(180) which is coupled to the rear side of the load-carrying element to inject grout, first and second grouting hoses(121) whose leading ends are respectively located in the innermost packer and in the innermost side of the excavated hole, a first coupling hose(131) which connects the packers to guide grout, a second coupling hose which connects spaces of the excavated hole to guide grout, and first and second air hoses(141) which are located inside the packer or space of the excavated hole, where grout is injection, in order to guide the grout.
