摘要： PROBLEM TO BE SOLVED: To provide a shield machine capable of preventing the occurrence of the problem of insufficient thrust likely to occur in a part of a deformed excavation cross section of a cutting edge even if the excavation cross section for the cutting edge is the deformed excavation cross section being unsymmetrical in upper and lower parts and/or right and left parts and an interval of arrangement of shield jacks is made equal along a peripheral fringe of the deformed excavation cross section. SOLUTION: A plurality of shield jacks 7 for letting a shield machine main body 3 advance by making use of reaction force of an existing segment 6 are arranged at an equal interval along the peripheral fringe of the deformed excavation cross section in the main body 3 of the shield machine 1. The deformed excavation cross section is virtually divided into two parts, namely, a large area part B and a small area part A by a virtual line X passing through the center G of the Figure showing the deformed excavation cross section and extended in the direction crossing the direction of advance of the machine main body 3 orthogonally. The large area part shield jacks 7b arranged in the large area part B among the shield jacks 7 include the shield jacks having larger jack thrust than jack thrust of the small area part shield jacks 7a arranged in the small area part A.

摘要： PROBLEM TO BE SOLVED: To construct an overlaid layer with a constant thickness with pneumatically- applied concrete as timbering for wall surfaces, on wall surfaces immediately after excavation ahead of a tunnel boring machine and eliminate various bad effects of pneumatically-applied concrete behind the tunnel boring machine. SOLUTION: A large diameter tunnel with a constant length is excavated by a front body section 1 being advanced, an excavation blade 14 protruding in the front of a rotary cutter plate 3 and an excavation blade 17 protruding in the circumferential edge in the diametrical direction in an extensible manner after the rear body 2 of a tunnel boring machine is supported on an already-constructed concrete overlaid layer C' through a rear gripper 6. And then, after the front body section 1 is retreated, with a spray nozzle 7 protruded from the opening 20 of the cutter plate 3 and the cutter plate 3 being turned, thick concrete over layer C is sprayed to the excavated wall surface T of a tunnel. Concurrently with the construction, the concrete overlaid layer C is reshaped to a concrete overlaid layer C' with constant thickness that is flat in the inside perimeter by the excavation blade 17 of the cutter plate 3 adjusted in a direction that reduces the diameter of the excavation blade 17 by a certain length by advancing the front body section 1.

摘要： PROBLEM TO BE SOLVED: To elevate a heavy load without attaching a weight regardless of an elevating distance. SOLUTION: A folded sheave 13 is installed on a following carriage 12. One-end of a first wire rope 14 wound around the folded sheave 13 is installed on an upper end of an arriving car 16, and the other end is installed on a first winch 19. The other end of a second wire rope 20 one end of which is installed on a lower end of the arriving car 16 is installed on a second winch 22 at the same height of the first winch 19. The second winch 22 is driven by a torque motor 23 rotation of which is controlled in accordance with tensile force T of the first winch 19 detected by a first tensile force detection part 25 and tensile force (t) of the second winch 22 detected by a second tensile force detection part 26. Consequently, it is possible to elevate the arriving car 16 without attaching a weight on the arriving car 16 regardless of an elevating distance L by drawing down the arriving car 16.

SOLUTION: Supporting portions 9 are movably provided along the longitudinal direction of each of two guides 8, in the two guides 8 which are arranged in a cutter frame 4, respectively. A portion, on the longitudinal inside with respect to a longitudinal end, of a beam-like variable beam 12 is rotatably supported on each of the supporting portions 9; a plurality of bits 18 are provided at the longitudinal end of the variable beam 12; either of the supporting portions 9 is moved along either of the guides 8; and the other supporting portion 9 is moved along the other guide 8, so that the longitudinal end of the variable beam 12 can be protruded to the radial outside of a rotary cutter 2. The width W1 of the bit 18a, which is arranged on the outermost periphery, among the plurality of bits 18 provided in the variable beam 12 is set greater than the widths W2 and W3 of the bits 18b and 18c which are arranged on the side of an inner periphery with respect to the bit 18a. When the cutter frame 4 is rotated once, the outermost periphery of an excavated hole is excavated by means of the bit 18a which is arranged on the outermost periphery. COPYRIGHT: (C)2008,JPO&INPIT

摘要： PROBLEM TO BE SOLVED: To support load without enlarging a cutter spoke supporting the load applied to an over-cutter. SOLUTION: Two guides 13 are arranged on a rotary cutter 3 in a manner that they make predetermined angles to each other in a peripheral direction of the rotary cutter 3. Supporting parts 32 are mounted on these two guides 13, respectively, to be movable along the longitudinal direction of each of the guides 13. Each of the supporting parts 32 supports the beam-like over-cutter 4 in a manner of being rotatable in the area that is longitudinally inside the longitudinally end parts. One of the supporting parts 32 is moved outward along the diameter of the rotary cutter 3 and the other supporting part 32 is moved inward along the diameter of the rotary cutter 3, by which one of the longitudinal end parts of the over-cutter 4 is protruded outward along the diameter of the rotary cutter 3.

摘要： PROBLEM TO BE SOLVED: To support an excavated wall surface so as not to be exposed from the shell body of a TBM. SOLUTION: A ring support 25 is geld into a skin plate 26 for a TBM 11 in a movable manner with the skin plate 6. A rod-shaped body 28 curved towards the outside of the tunnel radial direction is inserted into the through- holes 26, 29 of the new ring support 25 and an existing ring support 27, and a rear end is fixed into the existing ring support 27. The new ring support 25 is moved forward at a fixed distance while soil is excavated by the TBM 11. The new ring support 25 is pushed out to the outside of the skin plate 16 by a sliding jack 21, the diameter of the ring support 25 is expanded and the front end of the rod-shaped body 28 is fastened onto the new ring support 25. Consequently, an excavated wall surface 33 after the skin plate 16 is timbered by the ring support 25, 27,... and rod-shaped bodies 28, 30,... through all processes. Accordingly, the excavated wall surface can be timbered without exposure.

摘要： PROBLEM TO BE SOLVED: To prevent a bored wall surface from exposed from the shell of a TBM. SOLUTION: A ring support 25 is held within the skin plate 16 of a TBM 11 in such a way as to be movable along with the skin plate 16. A rod-shaped element 28 is passed through a through hole 26 in the new ring support 25 and is connected by a joint part 31 to an existing rod-shaped element 30 projecting from a through hole in an existing ring support 27. As boring proceeds using the TBM 11, the new ring support 25 is advanced by a predetermined distance. The new ring timbering 25 is pushed out of the skin plate 16 by a sliding jack 21, is increased in diameter, and secured to the wall surface of a tunnel. Thus, a wall surface bored ahead of the skin plate 16 is supported by the ring timbering 25, 27... and the rod-shaped elements 28, 30,... through all processes. Therefore, the wall surface bored can be supported without being exposed.
