PURPOSE: A leading end anchorage of an anchor is provided to increase the shear stress and bending moment resistivity. CONSTITUTION: A leading end anchorage of an anchor comprises a mounting head part, a pulling wire, and an extension elastic member(20). The installed wing comprises a denotation of an arc, an uneven steel, a through-hole, a combining projection, and a wire bonding ball. The uneven steel increases the frictional force in settlement. A through-hole is penetrated and formed in order for the rotation fixed axis to be axis-connected. The combining projection, projected on one side of the through-hole outside, combines one end of the extension elastic member. One end of the pulling wire is combined on the wire bonding ball. The extension elastic member is combined on the axis line between the installed wings, and is combined to expand to the outside underground on the anchor hole axis line expansion. |
