ROCK FALL PREVENTING METHOD

摘要

PROBLEM TO BE SOLVED: To provide a rock fall preventing method allowing easy and rapid construction. SOLUTION: A plurality of locking bolts are driven into the lower side of an object fragmented rock F, and reinforcements are connected to the heads of the locking bolts to form a planar reinforcement assembly 2. A net body is attached to the reinforcement assembly in the open state of a slope shoulder side face. Concrete with such properties as not to flow out of the meshes of the net body is then poured between the net body and the object slope from an opening of the slope shoulder side face. A retaining wall X for supporting the object fragmented rock F is thereby formed to prevent the fall of the rock. COPYRIGHT: (C)2004,JPO&NCIPI
