REINFORCEMENT STRUCTURE AND REINFORCEMENT METHOD OF EXISTING STEEL SHEET PILE WALL
PROBLEM TO BE SOLVED: To provide a reinforcement structure and a reinforcement method of an existing steel sheet pile wall, which can be constructed without removing a short strut structure even if an existing wall is a short strut type revetment, and avoid river-width reduction by suppressing extension toward waterside and requires no ground improvement.SOLUTION: An existing steel sheet pile wall reinforcement structure 1 according to this invention is formed of an U-shaped steel sheet pile or a hat-shaped steel sheet pile and has an irregular part that is alternately connected to a wall surface, and is horizontally supported around its head part by a short strut structure 27. The existing steel sheet pile reinforcement structure 1 comprises: a reinforcement member 5, which is installed so as to butt against a surface of a concavity 3a of the existing steel sheet pile wall 3; a lower short strut structure 7, which integrally supports lower parts of the reinforcement member 5 and the existing steel sheet pile wall 3; and an upper short strut structure 9, which is constructed on an upper end of the reinforcement member 5 and integrally supports the upper end of the reinforcement member 5 and an upper part of the existing steel sheet pile wall 3.SELECTED DRAWING: Figure 1
【課題】既設壁が切梁式護岸の場合においても、切梁構造の撤去なしで施工でき、水際側への張り出しを抑えて川幅の縮小を避けることができ、さらには地盤改良などが不要な既設鋼矢板壁の補強構造及び補強方法を提供する。【解決手段】本発明に係る既設鋼矢板壁の補強構造１は、Ｕ形鋼矢板もしくはハット形鋼矢板で構成され、壁面に凹凸部が交互に連続し、その頭部付近において切梁構造２７によって水平支持された既設鋼矢板壁の補強構造１であって、既設鋼矢板壁３の凹部３ａの表面に当接するように設置された補強部材５と、補強部材５の下部と既設鋼矢板壁３の下部を一体的に支持する下部支持構造７と、補強部材５の上端部に構築されて補強部材５の上端部と既設鋼矢板壁３の上部を一体的に支持する上部支持構造９とを備えたものである。【選択図】 図１
