Zusammenfassung:To carry out an installation work of a radial gate in a state where water discharge is possible in occurrence of a typhoon etc. even on the halfway of installation of the radial gate in an installation method of the radial gate.SOLUTION: In order to install a radial gate 10 which is rotatably supported by a pair of piers 3 around a horizontal rotation axis 10a and can adjust a flow amount of water flowing between the pair of piers 3, when arranging bars for placing concrete of the pair of piers 3, anchor pads 20 for fixing door body temporary stages 40 supporting the radial gate 10 in a state where a door body 12 is held in an open state of making water flow pass between the pair of piers 3 are respectively arranged in parallel at facing positions of facing faces of the pair of piers 3, and concrete 3a is placed in a state where the anchor pads 20 are disposed.SELECTED DRAWING: Figure 1 【課題】ラジアルゲートの設置方法において、ラジアルゲートの設置途中でも台風発生時などに放水可能な状態でラジアルゲートの設置工事を行う。【解決手段】一対のピア3に水平な回動軸10aを中心に回動可能に支持され、これら一対のピア3の間を流れる水の流量を調整可能なラジアルゲート10を設置するために、一対のピア3のコンクリート打設用配筋を行うときに、ラジアルゲート10を、その扉体12が一対のピア3の間の水流を通過させる開き状態に保たれた状態に支持する扉体仮設ステージ40を固定するためのアンカパッド20を、一対のピア3の対向する面における、対向する位置にそれぞれ並設し、これらのアンカパッド20が配置された状態でコンクリート3aを打設する。【選択図】図1
