摘要： PROBLEM TO BE SOLVED: To easily and rapidly assemble a branched shield machine by reducing the number of split parts of the branched shield machine for excavating a branched tunnel.
SOLUTION: A cylindrical body 4 for the start of the branched shield machine is used at the start of a first front barrel part 21 which excavates the branched tunnel from inside an existing tunnel 1. The cylindrical body 4 is mounted on an inner wall surface of the existing tunnel 1 which serves as an entrance of the branched tunnel, so as to allow the branched shield machine to be started from inside. The cylindrical body 4 is equipped with a cylindrical outer peripheral entrance 40 and an inner peripheral entrance 41 which is continuously arranged at the other end of an outer cylinder part. An inner peripheral surface of the peripheral entrance 41 is provided with a tube seal 6 which allows cut-off between the inner peripheral surface and an outer peripheral surface of the barrel part 21 which passes through a hollow part. In addition, the entrance 41 is provided so as to be axially slidable in the entrance 40.

SOLUTION: A cylindrical body 4 for the start of the branched shield machine 21 is used at the start of the shield machine 21 (e.g. a first front barrel part 21) which excavates the branched tunnel from inside an existing tunnel 1. The cylindrical body 4 is mounted on an inner wall surface of the existing tunnel 1 which serves as an entrance of the branched tunnel, so as to allow the shield machine 21 to be started from insider. A leading cylindrical material 4a is fixed to the inner wall surface of the existing tunnel 1, and a rear-end cylindrical material 4b is removably coupled to the cylindrical body 4a, and located in the rear of an excavating part 212 at the tip of the shield machine 21 when the excavating part 212 is arranged in a hollow part of the cylindrical material 4a. The cylindrical materials 4a and 4b are provided with tube seals 6 which allow cut-off between inner peripheral surfaces of the cylindrical materials 4a and 4b and the shield machine 21.

摘要： PROBLEM TO BE SOLVED: To provide a construction method for a branch tunnel easily dividing and cutting a concrete part by a shield machine and suppressing the generation of vibration and sound. SOLUTION: A plurality of sheath tubes 9a, etc., and 9b, etc., are provided along the circumferential and axial directions of a main tunnel 1 in its inside, and a branch segment part 2 provided with a plain concrete part 7 with prestressed steel products 10, etc., inserted in the circumferential sheath tubes 9a, etc., respectively is assembled as a part of the main tunnel 1. Then, the steel products 10, etc., are pulled out from the circumferential sheath tubes 9a, etc., static crush agent is filled with the circumferential and the axial sheath tubes 9a, etc., and 9b, etc., and crack is introduced in the plain concrete part 7 by the swelling pressure of the static crush agent. Then, the branch tunnel is constructed by cutting it by the shield machine 3 using the plain concrete part 7 as a starting shaft. COPYRIGHT: (C)2004,JPO

摘要： PROBLEM TO BE SOLVED: To provide a segment joint structure capable of easily connecting mutual segments, and capable of reducing a burden to the segments when tensile force acts between the segments after the connection. SOLUTION: A male joint member 2 and a female joint member 8 are embedded in mutual end parts of the connecting segments 1A and 1B. These male- female joint members 2 and 8 are formed so as to obtain a strong connecting state only by inserting the male joint member 2 into the female joint member 8 by using a lock ring 11 and a backup ring 12. A connecting shaft body 4 being a projecting member of the male joint member 2 is housed in a male joint body 3 so as to be movable in the shaft direction even after connecting the male-female joint members 2 and 8. A spring washer 6 is arranged for resisting the tensile force by being deformed when the tensile force acts between the male-female joint members 2 and 8.
