Abstract
PURPOSE: To safely remove a tension member without causing noises and scattering broken pieces by a method wherein a anchor main body around a tension member is cracked with the hardening and expansion of a slow control crushing agent and thereafter, a strand is pulled out.
CONSTITUTION: A tension member 2 which is its central part, has a hollow pipe 3 and plural pieces of strands 5 surrounding the outer circumference of the hollow pipe 3 is inserted into a formed hole 1 to the specified depth and a hardening agent is filled into the formed hole 1 to form an anchor main body 8. When the tension member 2 has finished its use as anchor, a slow control crushing agent 9 which is blended with water to form a fluidlike material is filled into the hollow pipe 3. When approximately 24 hours elapsed after the filling, the whole length of the anchor main body 8 is crushed by means of the hardening and expansion of the slow control crushing agent 9. The adhesive force of the strand 5 and the anchor main body 8 is nearly eliminated, as a result, the strand 5 can be easily pulled out.
