FOUNDATION REINFORCEMENT STRUCTURE
PROBLEM TO BE SOLVED: To make a soil pressure unlikely to directly act on a bridge abutment without requiring time and efforts in a foundation reinforcement structure in which an improvement body formed by mixing and solidifying sediment and a fixation agent is buried in a foundation that is supported by the bridge abutment.SOLUTION: A foundation support 5 of a foundation reinforcement structure 1 comprises: a first wall part 51 formed in the vicinity of the back of a bridge abutment 22 so as to be spread along a vertical plane that is substantially orthogonal with the bridge abutment 22; a second wall part 52 formed in the vicinity of the back of the bridge abutment 22 and in a location separated from the first wall part 51 in a horizontal direction by a predetermined distance so as to be spread along a vertical plane that is substantially orthogonal with the bridge abutment 22; and a third wall part 53 formed between an end portion of the first wall part 51 at the side of the bridge abutment 22 and an end portion of the second wall part 52 at the side of the bridge abutment 22 so as to be spread from the vicinity of an upper end of the bridge abutment 22 to the vicinity of a lower end of the bridge abutment 22 along the bridge abutment 22 and in such a manner that both side end portions are coupled with the first wall part 51 and the second wall part 52.SELECTED DRAWING: Figure 1
【課題】橋台によって支持された地盤の中に、土砂と固化剤とを混合、固化させてなる改良体が埋設された地盤補強構造において、手間をかけることなく、橋台に土圧が直接作用しにくくする。【解決手段】地盤補強構造１の地盤支持体５は、橋台２２の背面近傍に、橋台２２と略直交する鉛直平面に沿って広がるように形成された第１壁部５１と、橋台２２の背面近傍であって第１壁部５１から水平方向に所定距離離れた箇所に、橋台２２と略直交する鉛直平面に沿って広がるように形成された第２壁部５２と、第１壁部５１の橋台２２側端部と第２壁部５２の橋台２２側端部との間に、橋台２２に沿って橋台２２の上端近傍から橋台２２の下端近傍まで広がるように、かつ、両側端部が、第１壁部５１および第２壁部５２とそれぞれ結合するよう形成された第３壁部５３と、を有する。【選択図】図１
