COIL FORMING BODY LAYING DEVICE, COIL FORMING BODY LAYING METHOD, LINING METHOD AND REFORMED PIPE PASSAGE
PROBLEM TO BE SOLVED: To enable a work for laying a coil forming body into an existing pipe to be carried out further easily.SOLUTION: A coil forming body laying device comprises core members (20) having a hollow part and a diameter expansion device (60) separate from the core members (20), which can be moved within the hollow part of the core members (20). A plurality of core members (20) each of which holds a reduced diameter coil forming body (10) are drawn from a second man-hole (104) by a rope (108) passed through a first man-hole (102) into an existing pipe (100) under a state in which a connecting member (90) is connected. The coil forming body is removed by one diameter expansion device in an order from the core member near the first man-hole to expand the diameter. After a diameter of the coil forming body on the preceding core member is expanded, a subsequent core member is pulled toward a direction for the first man-hole to make an alignment in position of the coil forming body whose diameter is reduced on the subsequent core member.
【構成】 コイル成形体敷設装置は、中空部を有する芯材（２０）と、芯材（２０）とは別体であって芯材（２０）の中空部内を移動可能な拡径装置（６０）を含む。第１マンホール（１０２）を通したロープ（１０８）によって、各々が縮径したコイル成形体（１０）を保持した複数の芯材（２０）を、連結部材（９０）連結した状態で、第２マンホール（１０４）から既設管（１００）内に引き込む。第１マンホールに近い芯材から順に、１つの拡径装置によってコイル成形体を外すことによって拡径する。先行する芯材上のコイル成形体を拡径した後、後続する芯材を、第１マンホールの方向に引き寄せて後続する芯材上の縮径しているコイル成形体の位置合わせを行う。【効果】 コイル成形体を既設管内へ敷設する作業をより簡単に行えるようになる。【選択図】図３
