REINFORCEMENT BODY OF EARTH RETAINING WALL, AND INSTALLATION METHOD OF REINFORCEMENT BODY
To provide a reinforcement body and an installation method of the same which secures safety against a disaster by preventing collapse of an existing retaining wall to a sloped face side and preventing settlement of an existing retaining wall in an inland earthquake even when a large machine for an installation construction of a reinforcement body of an earth retaining wall cannot be carried-in in a case where a building exists near a retaining wall side in a developed land that is formed as a flat ground at an upper side of an earth retaining wall provided in a sloped land.SOLUTION: As to a building near a retaining wall side and a reinforcement body H of a retaining wall where a flat ground is formed at an upper side of an earth retaining wall provided in a sloped land S, the reinforcement bodies are provided in parallel at a sloped face side at a lower part of the retaining wall, and leg portions extending in a horizontal direction from a lower side base portion of the reinforcement bodies to the sloped face side are integrally formed. A plurality of hollow steel pipe piles are formed in the leg portion so as to extend to an underground side, and the inside is filled with reinforcement materials, to prevent collapse of the retaining wall.SELECTED DRAWING: Figure 1
【課題】傾斜地に設けた土留め擁壁の上部側に平坦地を形成した造成地であって、擁壁側に近接して建造物が存在する場合、土留め擁壁の補強物設置工事をするために大型機械を搬入することができない場合であっても、既存の擁壁を斜面側への倒壊を防ぐだけでなく、直下型地震の際における既存の擁壁が沈下するのを防ぎ造成地は災害に対して安全を確保する補強体およびその設置工法を提供する。【解決手段】傾斜地Ｓに設けた土留め擁壁の上部側に平坦地を形成し擁壁側に近接する建造物および擁壁の補強体Ｈにおいて、補強体を擁壁下部の斜面側に隣接して併設するとともに、補強体の下側基部から斜面側へ水平方向に延びる脚部を一体形成し、脚部には複数の中空鋼管杭を地中地盤側へ延伸させて形成するとともに内部を補強材で充填して擁壁の倒壊を防止するように構成した。【選択図】図１
