Abstract

PURPOSE: To transmit the supporting force of a rock anchor over the wide range of a rock bed by burying a welded wire mesh and a guide member in shotcrete and fixing the rock anchor inside the guide member. CONSTITUTION: The welded wire mesh 11 and the guide member 12 are attached to respective reinforced supports 10 built in the rock bed G, attaching concrete 1 is executed separately in four layers 1a-1d and the supports 10, the welded wire mesh 11 and the guide member 12 are buried in the concrete 1. Then, a bore hole 5 is formed from the inner side of the guide member 12 to the rock bed G, a PC steel material 7 is arranged and fixed in the inside and a grouting material 13 is filled inside the guide member 12. Then, the tension force of the rock anchor 2 is transmitted to the rock bed G over the wide range, the rock bed G is supported by the concrete 1 with the fixed part of the rock anchor 2 as a fulcrum and reliability is improved.
