摘要： PROBLEM TO BE SOLVED: To provide a segment assembling device used for a construction method for renewal of a head race, which can secure required strength even when applied to a large-diameter existing sewer, provide high strength, secure quality of execution, and enhance workability by enabling the reliable execution at a waterless site even during passage of water. SOLUTION: The segment assembling device is used for the construction method for the renewal of the head race, in which a segment piece 1a is assembled inside the existing sewer 2. A gripper 6, which serves as a fixing means for fixing a pipe jacking machine body 3 to the existing sewer 2, is provided in the machine body 3 which is brought into contact with the inside of the existing sewer 2 and equipped with a propulsion jack 5. An erector 7 for holding the segment piece 1a carried into the existing sewer 2 is disposed inside the machine body 3 so as to be freely turnable in a circumferential direction of the machine body 3.

摘要： PROBLEM TO BE SOLVED: To adjust a clearance of an inside diameter of an insertion hole and a diameter of a bolt shaft to prevent a water leakage and improve the appearance by pressfitting a sheath pipe having a tapered outside diameter into a bolt insertion hole in end parts of segments connected mutually. SOLUTION: A bolt insertion hole B passes through from an inner peripheral side of a segment to a recessed section provided by boring from an end part connection face s of segments 1 connected mutually, and a bolt seat z is formed on a through face. The bolt insertion hole B is thick for a shaft diameter of a bolt 3 to provide allowance and is tapered from a connection face s side for the purpose of blanking. A sheath pipe 4 is pressfitted the bolt insertion hole B of the segment 1 from the connection face s side. The bolt 3 is inserted with a slight clearance for an inside diameter of the sheath pipe 4 to connect the segments 1 mutually. Consequently, the irregularity in the connection of the segments 1 is slight, and join faces s of the segments 1 adhere closely and mutually to prevent a water leakage.
