SCOUR PREVENTION STRUCTURE FOR ABUTMENT AND BRIDGE PIER
PROBLEM TO BE SOLVED: To provide a scour prevention structure for an abutment and a bridge pier which has little influence on bearing ground of an existing foundation after and during construction thereof.SOLUTION: A scour prevention structure 1 for an abutment 5 supporting a bridge girder 3 comprises: a pair of reaction piles 7 driven close to the abutment 5 with the bridge girder 3 placed in between; and a linear steel sheet pile wall 11 constructed in a manner that surrounds a river side of the abutment 5 by connecting a plurality of linear steel sheet piles 9 with the steel sheet piles arranged at both ends of a wall respectively connected to the pair of reaction piles 7. A region surrounded by the linear steel sheet pile wall 11 is filled with a filling material 13.SELECTED DRAWING: Figure 1
【課題】設置後において既設基礎の支持地盤に与える影響が少ない構造であり、また施工時においても既設基礎の支持地盤に与える影響が少ない橋台及び橋脚の洗掘防止構造を得る。【解決手段】本発明に係る橋台の洗掘防止構造１は、橋桁３を支持する橋台５の洗掘防止構造であって、橋台５の近傍であって、橋桁３を挟んで打設された一対の反力杭７と、複数の直線形鋼矢板９を連結して橋台５の河川側を囲むように打設すると共に両端に配置された直線形鋼矢板９を一対の反力杭７にそれぞれ連結してなる直線形鋼矢板壁１１とを備え、直線形鋼矢板壁１１で囲まれた領域に充填材１３を充填してなることを特徴とするものである。【選択図】 図１
