Document Type and Number:
Japanese Patent JP7260768
Kind Code:
B2
Abstract:
To provide a sloped face reinforcement structure capable of obtaining proper sloped face reinforcement effect regardless of collapse mode of a sloped face.SOLUTION: In a sloped face reinforcement structure, a reinforcement structure body 100 comprising a plurality of reinforcement members is inserted into a sloped face. The reinforcement structure body 100 comprises: a first reinforcement member 101 which is constituted of a rod member and whose one end is inserted into the sloped face; a second reinforcement member 102 which is constituted of a rod member and whose one end is inserted at a position higher than the insertion position of the first reinforcement member 101 in the sloped face; and a connection member 103 connecting the other end of the first reinforcement member 101 and the other end of the second reinforcement member 102 with each other. The first reinforcement member 101 is installed so that it is substantially or the other end is at a lower position than one end. An installation angle θ2 of the second reinforcement member 102 to a sliding surface of the sloped face is larger than, at least, an installation angle θ1 of the first reinforcement member 101.SELECTED DRAWING: Figure 4
