A removable ground anchor. This anchor comprises a cylinder (10), an anchor disassembling cone (20) placed at the center of the cylinder (10) and a plurality of anchor tensioning cones (20') placed about the anchor disassembling cone (20). The anchor disassembling cone (20) tightens an anchor disassembling tensile member (W) while the anchor tensioning cones (20') tighten the anchor tensioning tensile members (W'). The anchor is easily removed from the ground hole after grouting and curing of grouting material. This invention also provides a method for anchorage using the above removable ground anchor and removing the ground anchor from the ground hole after grouting and curing. The anchor tensioning cones (20') are easily disassembled by simply removing the anchor disassembling cone (20). The anchor tensioning tensile members (W') are thus free from the cured grouting material and easily pulled out so as to be removed. The ground anchor also increases the tensile force to several times or several ten times in comparison with the prior art anchor, thus to reduce the number of ground holes per unit area and to save the construction cost. |
