BLOCK FOR STABILIZING BEDROCK SLOPE AND METHOD AND EQUIPMENT FOR ALIGNING ANCHOR MATERIAL IN CONNECTING SECTION WITH ANCHOR MATERIAL FOR FIXING BLOCK THEREOF ONTO BEDROCK

摘要

PROBLEM TO BE SOLVED: To align an anchor material in a connecting section between a block installed for stabilizing a bedrock slope and the anchor material for fixing the block onto a bedrock simply and economically. ;SOLUTION: The aligning method of the anchor material uses an eccentric liner 8 eccentrically having a tapered hole 8a, which has an outer circumferential surface fitted to a tapered hole 2a formed to the block 2 and to which an anchor-material head-section support member 4 is fitted. The eccentric liner 8 is inserted into the block tapered hole 2a in a combining section between the beforehand installed anchor material and the block 2 arranged onto a mounting surface at that time, and the eccentric liner 8 is rotated in the block tapered hole 2a so that the center line 8b of the eccentric-liner tapered hole 8a is directed in the same direction as the direction of extension of the anchor material.;COPYRIGHT: (C)1998,JPO
