Abstract

PURPOSE: To prevent occurrence of a gap by inserting a mat that a hydraulic material is enclosed in a bag body in the head of a rock bolt protruded from the surface of shotcrete and disposing a bearing plate and a nut at the outside of the mat and tightening the nut.
CONSTITUTION: Concrete is sprayed on a hole wall 1 to form shorcrete 2. Then, a bolt hole is bored to pierce the concrete 2 and the natural ground and a solidifying material 7 is injected in the hole. Thereafter, a rock bolt 3 is inserted in the hole. Subsequently, a mat 6 that a hydraulic material 62 is enclosed in a bag body 61 is put onto the bolt 3 head protruding from the surface of the concrete 2. Then, a bearing plate 4 is fitted to the bolt 3 head and a nut 5 is fastened. Moreover, the mat is pressed and squashed and respective faces of the mat 6 get close to the plane of the bearing plate 4 and the rugged surface of the concrete 2 and come into close contact therewith.
