摘要： PURPOSE: To facilitate a curve-like excavation by connecting a front barrel and a middle barrel, forming the middle barrel with outside and inside skin plates, forming the outside skin plate with a front barrel member, a rear barrel member, and a small-diameter connecting barrel member, storing a branch line excavator in the inside skin plate, providing an advance window hole on the periphery, and connecting the rear end to the rear barrel. CONSTITUTION: When a jack 5 is extended, a rear barrel 130 and the inside skin plate 122 of a middle barrel 120 are connected by a folding jack 4. The skin plate 122 and a front barrel 110 are connected, and a skin plate 121 and the front barrel 110 are connected by a folding jack 3, and they are integrally advanced. The folding jacks 3, 4 are operated for the excavation of a bent main line tunnel, and the connecting angles of the front barrel 110, middle barrel 120, and rear barrel 130 are changed to cope with the prescribed curvature. An excavator 200 is advanced from the window hole of the skin plate 122 for the excavation of the branch line. The bent tunnel can be easily excavated.

摘要： PROBLEM TO BE SOLVED: To solve a problem that in a shield machine whose diameter can be expanded or contracted during the excavation of a tunnel, when the diameter is expanded, a ring-shaped recess is formed on the outer periphery of an inner bent section and earth and sand penetrates into the recess so that the bent resistance of the bent section increases. SOLUTION: When a diameter is in an expanded state, a second front drum 3 is provided outside a first front drum 2 and a second rear drum 5 is provided so as to extend to the outside of a front end member 4a of a first rear drum having the same diameter as that of the drum 2. And a filler injection device 26 is provided to inject a filler (mud additive or slurry) into a ring-shaped recess 25 on the outer periphery of an inner bent section 6. A filler is injected into the recess 25 to maintain the pressurized condition of the recess 25 higher than the earth pressure or hydraulic pressure of the ground, and the filler is supplied properly.

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.

摘要： PROBLEM TO BE SOLVED: To miniaturize a shaft for assembly, and to reduce the cost of tunnelling by disposing a plurality of shield jacks on the inside of an intermediate drum and shortening the length of a shield machine. SOLUTION: When a plurality of shield jacks 13 are arranged into the internal drum 21 of an intermediate drum 3, the length of a main-line shield excavator 1 is lengthened, and only the front section of the intermediate drum 3 is formed in the triple structure of the internal drum 21, an external-drum internal cylinder section 25 and a front-drum tail section 23. Since the rear section of the intermediate drum 3 is formed in the double structure of the internal drum 21 and an external-drum main body 24, the structure of the intermediate drum 3 is simplified. Since a branch shield excavator reaches a branch point and is carried in, a space in the intermediate drum 3 can be ensured largely, an earth removing device 10 discharging excavated materials can also be installed, and shield excavation is carried out in both a main-line tunnel and a branch tunnel. Since the length of the main-line shield excavator 1 is shortened, the main-line shield excavator 1 can be charged and a shaft for assembly miniaturized.

摘要： PROBLEM TO BE SOLVED: To construct a branch tunnel from a main track tunnel without installing a vertical shaft from the ground or improving the ground. SOLUTION: After a special ring wall 7 of cylindrical shape with a branch start opening 11 is built up in a drum part 2 of a shield machine l, a propulsion machine for constructing a branch tunnel is carried into the special ring wall 7. After bringing the propulsion machine close to the inner peripheral surface of the drum part 2 of the shield machine 1, the shield machine is made excavate forward. The start opening 11 is thereby exposed to the natural ground. A cylindrical ring wall is then constructed at the rear end part while making the propulsion machine excavate forward. The branch tunnel is therefore constituted without installing a vertical shaft from the ground or improving the ground.

摘要： PROBLEM TO BE SOLVED: To need no replacement of an eccentric fitting by forming a plurality of the projection spherical face engaging part of an eccentric fitting at the position of a radius different from the shaft center of a jack body and at the position of a phase different in the circumferential direction as a jack body shaft center is made a reference. SOLUTION: A plurality of shield jacks 12 are fixed on the ring member 15 of a shield machine provided in the excavation of the first tunnel of a smaller diameter than a second tunnel. Projection spherical face engaging parts 17a, 17b different in a circumferential phase as two eccentric diameters and a jack body shaft center are made a reference are previously provided on the eccentric fitting 17 of each shield jack 12. Therefor these plural shield jacks 12 can be applied to the excavation of the first tunnel and the second tunnel only by rotating the eccentric fitting 17 of each shield jack 12 up to 90 degrees and switching the projection spherical face engaging parts 17a, 17b. Thus, need for replacing a plurality of the eccentric fitting is eliminated, and it is very advantageous in labor and a facility cost.

摘要： PURPOSE: To immediately conduct a branch excavation with safety by providing the advance window hole of a branch shield machine on a skin plate, blocking it with a filler, connecting a guide tube section on the inside, and storing the branch excavator in the tube section. CONSTITUTION: The front barrel, middle barrel, and rear barrel of a main line shield machine 10 are connected to folding jacks respectively. The excess excavation quantity is reduced, and the advancing direction can be easily changed. The advance window hole 12 of a branch excavator 20 is provided on a skin plate in advance, and a guide tube section 13 is connected on the inside. The tip of the tube section 13 is integrally connected to the skin plate along the inner periphery of the window hole 12. The window hole 12 is blocked with a filler such as mortar. The tip of the branch excavator 20 is stored in the tube section 13 in the main line excavator 10. When the main line excavator 10 is advanced to the expected branch place, the filler is excavated by the excavator 20, and the excavator 20 is advanced in a branch line tunnel. The branch line tunnel can be excavated with good workability.

摘要： PURPOSE: To easily and safely open an advance window hole by providing the advance window hole of a branch excavator on the skin plate of a main like shield machine, providing a window hole at the position adaptable to the advance window hole on the inner barrel of the skin plate, connecting a guide tube section to it, and inserting a branch excavator into the tube section. CONSTITUTION: The first advance window hole 12 of a branch shield machine 20 is provided on a skin plate 11 in advance. A main line tunnel is excavated while the window hole 12 is closed, and an inner barrel 11a is rotated when the main line tunnel is excavated to the expected branch place. The window hole 12 is matched with the second advance window hole 14 provided on the inner barrel 11a, and the window hole 12 is opened. The brach shield machine 20 is advanced through the window holes 12, 14. When the shield machine 20 is completely advanced from the window hole 12, excavations are restarted in parallel. The window hole 12 of the shield machine 20 can be easily opened when the inner barrel 11a is merely rotated.
