HOUSING TYPE REINFORCEMENT MEMBER, AND REINFORCEMENT METHOD AND REINFORCEMENT STRUCTURE OF FLANGE JOINT PART OF STEEL SLIT DAM USING MEMBER
PROBLEM TO BE SOLVED: To provide a housing type reinforcement member, and a reinforcement method and reinforcement structure of a flange joint part of a steel slit dam that uses the member, capable of preventing, as much as possible, opening or core deviation caused by impact boulder or the like, by enhancing shear resistance force and bending resistance force as well as protecting the flange joint part from direct hitting with boulder.SOLUTION: A housing type reinforcement member reinforces a flange joint part of flanged steel pipes constituting a steel slit dam provided between concrete banks on both sides of a river along a transversal direction. It includes a U-like groove that covers an entire circumference of the flange joint part, comprising a plurality of arc-like segments divided along a radial direction when viewed along a pipe axis direction of the steel pipe, and abutment jointing is made so as to cover the entire circumference of the flange joint part.SELECTED DRAWING: Figure 1
【課題】フランジ接合部を巨礫の直撃から護ることはもとより、せん断抵抗力および曲げ抵抗力を高めることにより、巨礫の衝撃等による開き、又は芯ずれを極力防止できる、ハウジング型補強部材ならびに同部材を用いた鋼製スリットダムのフランジ接合部の補強方法および補強構造を提供する。【解決手段】河川の横断方向両岸のコンクリート堤体間に設けられる鋼製スリットダムを構成するフランジ付き鋼管同士のフランジ接合部を補強するハウジング型補強部材であって、前記フランジ接合部の全周を覆う略コ字形溝を備え、前記鋼管の管軸方向からみて、径方向で分割された複数の円弧状セグメントからなり、前記フランジ接合部の全周を覆うように突き合わせ接合される。【選択図】図１
