Abstract

PURPOSE: To enable easy pulling-off of an anchor from a ground, by a method wherein the anchor consists of a plurality of steel materials, one of the steel materials is coated with resin, said steel material can make electrical connection with other steel materials, and the friction resistance of the resin is reduced through the power conduction at the time when the anchor is pulled off.
CONSTITUTION: An anchor 10 is inserted into a hole 11 formed in a ground 6, and the hole is filled with a grout material 12 to form an anchor trunk body 13. A tensile force from a sheathing wall 5 and an anchor head 10' is held by the anchor trunk body 13 through the anchor 10. The anchor 10 consists of at least a resin- coated insulation steel material 10a and other steel materials 10b and 10g, and the end of the insulation steel material 10a makes electrical connection with one of other steel materials 10bW10g. In case the anchor 10 is to be recovered, electricity is charged between the end of the coated insulation material 10a and other steel materials to reduce the friction resistance of the resin, and the coated steel material is first pulled off and other steel materials are then pulled off.
