Summary:PROBLEM TO BE SOLVED: To properly repair a support structure for supporting a supported body in a short time, when a height dimension of the supported body is changed and an installation top end level of the supported body is not changed.SOLUTION: A grout 140 is placed between a rail 100 and an existing concrete foundation 112 in the formwork, while a base plate 130, a rebar 133 and an anchor 134 are disposed in a formwork, after chipping an upper surface of a concrete foundation 112. The grout 140 has a self-flowing flow value while the rebar 133 and the anchor 134 are disposed, and has a strength equal to or higher than that of concrete. 【課題】被支持体の高さ寸法が変更され、かつ被支持体の据付天端レベルを変更しない場合に、当該被支持体を支持する支持構造体を短時間で適切に補修する。【解決手段】コンクリート基礎１１２の上面を斫った後、型枠内にベースプレート１３０、鉄筋１３３及びアンカー１３４を配設した状態で、当該型枠内であって軌条１００と既設のコンクリート基礎１１２との間にグラウト１４０を打設する。グラウト１４０は、鉄筋１３３及びアンカー１３４が配設された状態で自己流動するフロー値を有し、且つコンクリートと同等以上の強度を有する。【選択図】図９
