Abstract

PURPOSE: To enable pulling out the whole of tension members easily from the trunk body of an anchor without any noise throughout the full length of the trunk of the anchor in which the tension members are buried.
CONSTITUTION: A tension member 2 which has a core line 3 in its center and is formed of plural number of strands 4 surrounding the outer periphery of the core line 3 is arranged in a hole 1 dug for the trunk of an anchor. Next, hardening materials are struck and thus the trunk body of the anchor 5 is formed. After that, the core line 3 in the above tension member 2 is pulled out and a cavity produced by the pull-out of the core line is filled with a slow fracture agent 6 mixed with water and prepared to be liquefied state. By the hardening and swelling of the slow fracture agent 6, the trunk body of the anchor 5 around the tension member 2 is fractured throughout the whole length thereof and after that plural number of P.C strands 4 are pulled out.
