CONSTRUCTION METHOD FOR SOIL MORTAR RETAINING WALL AT CORNER
To provide a construction method for a soil mortar retaining wall at a corner that suppresses the occurrence of cracks at a corner that is convex toward the excavation side, in corners of the retaining wall.SOLUTION: A special core material 22 is built in a corner 12 where first and second soil-mortar walls 11 and 13 intersect. The special core material 22 is composed of ordinary core material 20 (H-shaped steel) arranged diagonally and has a protruding portion 26 from the center of a web surface to the corner. After the construction of a retaining wall 10, prior to excavation of the inside of the wall, the perimeter of the excavated side of the corner 12 is partially excavated. Then, at the partially excavated area, deformation-preventing steel 30 (and steel plates 32) are installed in an L-shape in plan view to restrain the excavated side of the corner 12.SELECTED DRAWING: Figure 2
【課題】山留壁の隅角部のうち、掘削側に凸となる出隅部でのクラックの発生を抑制するソイルモルタル山留壁出隅部の施工方法を提供する。【解決手段】第１及び第２のソイルモルタル壁１１、１３が交差する出隅部１２には、特殊芯材２２を建て込む。特殊芯材２２は、通常の芯材２０（Ｈ形鋼）を斜めに配置してなるとともに、ウェブ面の中央からコーナー部に向かう突出部２６を有する。山留壁１０の構築後に、その内側を掘削するに先立って、出隅部１２の掘削側の周囲を部分掘削する。そして、部分掘削箇所に、出隅部１２の掘削側を拘束するように、平面視でＬ字状に変形防止用鋼材３０（及び鋼板３２）を設置する。【選択図】図２
