Abstract:
PURPOSE:To eliminate traffic jam during construction by forming an anchor material from a bendable steel coil wire to fit it firmly to an anchor hole on a roadbed hill side, and placing a protruding material after setting the head part of the steel coil wire along the mountain side at the time of installing the protruding material. CONSTITUTION:An anchor material 2 is constituted from a bendable and flexible anchor member 3 and is formed from a steel coil wire or the like. Besides, a slope surface is taken off to provide an excavated hole 4 on the mountain side of a formed roadbed 1, and to construct a support pile 8 at the mountain side. Next, the anchor member 3 is inserted and disposed in the excavated hole 4, and its lower part is filled with a hardening agent 5 such as cloud to be fixed. At this time, a protruding material 9 or the like is placed after bending the head part of the anchor member 3 along the roadbed 1 surface.
