<p>PROBLEM TO BE SOLVED: To provide a slope reinforcement method which alleviates stress concentration on the vicinity of a connection part between a precast plate and a rod-shaped reinforcement material, and which prevents a slope in a state of excavation without shoring from collapsing, even in the case of a sharp slope.SOLUTION: A slope 2 in a state of excavation without shoring can be maintained without collapsing, by ground reaction on the side of the slope 2, which is generated by pressing precast plates 1, 1a... against the slope by an axial force Facting on a pile body 10 formed of a rod-shaped reinforcement material 7 and a hardened grout material in the upper stage precast plates 1, 1a... at the stage of hanging the lower stage precast plates 1, 1a..., and an axial force Facting on the pile body 10 by tightening a nut 8 in a nut tightening step in the upper precast plates 1, 1a.... Thus, stress concentration on the vicinity of a connection part is alleviated to enable inhibition of deformation on the side of the slope 2.</p> |
