PROBLEM TO BE SOLVED: To provide a joining method of segments favourable in workability while preventing intrusion of moisture to a hole part to insert a PC steel material to introduce prestress to each of the segments through and the segments to use for it. SOLUTION: A sheath to insert the PC steel material through it is integrally buried previously on each of the segments, and the segments are connected to each other while inserting connecting members by straddling on the sheath of the segments to be connected to each other. Additionally, an end part member to be installed on an end part of a sheath main body has a bell-mouth part on its head end, but a straight part is further provided on a head end of the bell-mouth part. |
