REINFORCING STRUCTURE FOR BEDROCK SLOPE WITH LONG-TERM DURABILITY AND CONSTRUCTION METHOD THEREOF

摘要

PROBLEM TO BE SOLVED: To provide a reinforcing structure and a construction method thereof capable of not only ensuring a long-term durability by preventing toppling failures of a bedrock slope and landslides of a bedrock but reducing construction cost as using pressure plates is not needed.;SOLUTION: A reinforcing structure is constructed by: arranging one or a plurality of reinforcing members 2 through one hole 1 or a plurality of holes 1 drilled across from a slope S to a moving bedrock region G₁ and immovable bedrock region G₂, each of which is longer than 5 m and equal to or less than 100 m; filling grout material 7 around the reinforcing member 2 in the drilled hole 1; and forming an anchoring zone for the reinforcing member 2 in both of the regions by curing the grout material 7.;SELECTED DRAWING: Figure 1;COPYRIGHT: (C)2018,JPO&INPIT
