<P>PROBLEM TO BE SOLVED: To provide an anchor for non-self-supporting structure which can maintain stable bearing force with a simple structure and is also excellent in workability; and an anchor construction method. <P>SOLUTION: An anchor 1 is installed by inserting an anchor body 2 comprising a wire rope in a hole 3 bored from a slope face a to a rock layer c in a right angle shape so as to make a non-self-supporting structure supported on an exposed rock slope face a with a rope and fixing the anchor body 2 to the inside of the hole 3 with a fixing coagulant 4. The anchor 1 is established by a method in which a bedrock ground surface part corresponding to the opening of the hole is shaped into an arcuate surface over the inside of the hole 3 and in which the upper part of the anchor body 2 extended to project from the hole 3 is led to be along the arcuate surface of the bedrock ground surface part. <P>COPYRIGHT: (C)2013,JPO&INPIT |
