EARTH RETAINING FRAME, AND CONSTRUCTION METHOD THEREOF
PROBLEM TO BE SOLVED: To provide an earth retaining frame that allows excavation in a short period of time, even when a site on a rear side of an earth retaining wall is narrow or when there is no anchoring ground behind the earth retaining wall.SOLUTION: An earth retaining frame 1 includes an earth retaining wall 10 extending in a vertical direction, a plurality of stay piles 20 installed in a ground on an opposite side of an excavated region side of the earth retaining wall 10, a second wale 22 for connecting the stay piles 20 to each other, and a connecting member 30 connecting the earth retaining wall 10 and the stay pile 20 in a tensile state. According to the invention, the earth retaining wall 10 is supported only if a space for driving the stay pile 20 may be secured on a rear side of the earth retaining wall 10, even when a site on the rear side of the earth retaining wall 10 is narrow. The earth retaining wall 10 is supported also when a height of the earth retaining wall 10 is high, because the connecting member 30 pulls the earth retaining wall 10 toward the rear side. The earth retaining frame 1 may be constructed in a short period of time, because labor may be saved for excavation work as a structure for the earth retaining frame 1 is not needed on the excavated region side of the earth retaining wall 10.SELECTED DRAWING: Figure 1
【課題】山留壁の背面側の敷地が狭い場合や、山留壁の背面にアンカー定着地盤がない場合であっても、短工期で掘削できる山留架構を提供すること。【解決手段】山留架構１は、鉛直方向に延びる山留壁１０と、この山留壁１０の掘削領域側とは反対側の地盤に設けられた複数の控え杭２０と、控え杭２０同士を連結する第２腹起し２２と、山留壁１０と控え杭２０とを緊張状態で連結している連結部材３０と、を備える。本発明によれば、山留壁１０の背面側の敷地が狭い場合でも、山留壁１０の背面側に控え杭２０を打ち込むスペースを確保できればよく、山留壁１０を支持できる。また、山留壁１０の高さが高い場合であっても、連結部材３０で山留壁１０を背面側に引っ張るので、山留壁１０を支持できる。また、山留壁１０の掘削領域側に山留架構１のための構造物が不要となるので、掘削作業に手間がかからないから、短工期で山留架構１を構築できる。【選択図】図１
