PURPOSE:To construct earth anchors having comparatively great drawing resistance at low cost by a method in which wings attached to the tip of an anchor body are opened by a pulling tool, and the wings portion is covered with cement milk, etc. CONSTITUTION:An anchor body 11 and a guide pipe 12 are inserted into a lower hole provided in a retaining wall, the guide pipe 12 is supported outside, to support the supporting pipe 1 of the anchor body 11, and then a pulling tool 8 is pulled. Whereupon, a pin 7 is pulled through a connecting tool 6 and the wings are opened outwards to some extent. The guide pipe 12 is pulled out and then the pulling tool 8 is strongly pulled to completely open the wings 3. A grout 24, e.g., cement milk, is injected into the lower hole to cover the wings portion with the grout, whereby forming an anchor body 25. |
