INSERTION TOOL FOR SHEATH CONNECTION PORT MOLDING, MOLDING METHOD OF SHEATH CONNECTION PORT AND INSTALLATION METHOD OF CONCRETE SEGMENT
To form a sheath connection port with a simple structure which resists displacement securely without concrete peeling damage.SOLUTION: On an insertion tool 410 for molding a sheath connection port are provided core material 411 which has a smaller outer diameter than the inner diameter of the opening end 3a of a pair of sheath connection pipes 3 embedded in the opposite positions on the end surface 2a of a pair of concrete segments 2 which are formed in a state of being butted to each other through a formwork 1 and on which the rubber sheet 13 is inserted in a state of being wound around the opening end of the pair of sheath connection pipes, and a diameter enlarging flange 411a which is connected to the core material, has a larger outer diameter than the outer diameter of the open end of the pair of sheath connection pipes and in contact with the formwork 1.SELECTED DRAWING: Figure 6A
【課題】簡単な構成でずれることなく確実にコンクリートの剥がれ損傷のないシース接続口を形成する。【解決手段】シース接続口成形用挿入具４１０に、型枠１を介して突き合わされた状態で成形される一対のコンクリートセグメント２の端面２ａにおいて、対向する位置に埋め込まれる一対のシース接続管３の開口端３ａの内径よりも小さな外径を有し、一対のシース接続管の開口端にゴムシート１３が巻き付けられた状態で挿入される芯材４１１と、芯材に連結され、一対のシース接続管の開口端の外径よりも大きな外径を有し、型枠１に当接する拡径フランジ４１１ａとを設ける。【選択図】図６Ａ
