摘要： PROBLEM TO BE SOLVED: To provide an assembly structure for a tunnel lining member capable of performing installation and disassembly easily and quickly in the circumference direction of the tunnel lining member. SOLUTION: In formation of a ring-type lining body covering the inner circumferential face of a tunnel by assembling a plurality of arc-shaped tunnel lining members 21-24, circumferential joint parts between the respective lining members 21-24 are jointed by means of temporarily engaging means 26, 27, while an expansible joint is arranged in at least one joint part between the lining members 21-24 for expanding/shrinking the joint part. In this assembly structure for the tunnel lining member, the expansible joint is a turnbuckle 28 provided with a pair of inverse threads 30, 31 connecting the both ends to the respective connection parts and a length regulating nut part 32 screwed to the inverse threads 30, 31.

摘要： PROBLEM TO BE SOLVED: To constitute a solidifying material injection pipe to be cuttable together with a natural ground reinforcing pipe when excavating the natural ground and to facilitate carrying the solidifying material injection pipe into the field and installation into the natural ground reinforcing pipe.
SOLUTION: The solidifying material injection pipe 1 for injecting a solidifying material into the natural ground reinforcing pipe 15 is formed by connecting, through pipe joints 7, a plurality of short pipes 2, 3, 4 formed of a hard material cuttable together with the natural ground reinforcing pipe 15. The solidifying material injection pipe 1 is formed in such a length that one end is inserted in the natural ground reinforcing pipe 15 and that the other end is pulled out of the natural ground reinforcing pipe 15. When excavating the natural ground, the solidifying material injection pipe 1 can be cut together with the natural ground reinforcing pipe and removed together with excavated sediment. Since the plurality of short pipes are sequentially connected through the pipe joints to form the predetermined length, carrying into the field and installation into the natural ground reinforcing pipe can be easily performed.

摘要： PROBLEM TO BE SOLVED: To provide a method for controlling a direction in horizontal drilling which is available in a soil improving method depending on high-pressure injection. SOLUTION: In implementing the method for controlling the direction in horizontal drilling, there is provided a drill rod which is comprised of a cylindrical rod main body having a wedge-like tip, and an overcut bit attached to a peripheral surface of the rod main body in the vicinity of an apex of the tip portion. When no deviation from a straight forward direction is sensed, the rod main body is oscillated in a range of a first oscillating angle with respect to a predetermined orientation as a center of the first oscillating angle while being drilled forward, to thereby advance the rod main body in a straight forward direction. On the other hand, when deviation is sensed, the rod main body is oscillated in a range of a second oscillating angle with respect to an orientation opposite to a deviating direction as a center of a second oscillating angle, while being drilled forward. In this manner, the drilling direction of the drill rod can be corrected. COPYRIGHT: (C)2003,JPO

摘要： PROBLEM TO BE SOLVED: To provide a simple liner that can be installed easily by eliminating the need for uneven shaping. SOLUTION: A liner 30 is provided with a crown piece 30a that is installed at the crown part of an excavation surface, a pair of side pieces 30b that is arranged at both the side surface sides of the excavation surface, and a diameter-expansion maintenance member. The area between the piece 30a and each piece 30b is in a hinge connection including a pin 30d. When the liner 30 is to be installed, it is carried to the rear end side of a TBM while it is folded. Then, the piece 30a is pressed to the crown part of the excavation surface, and at the same time the piece 30b is pressed to both the sides of the excavation surface. When the piece 30a and the piece 30b have been pressed to the excavation surface, the diameter-expansion maintenance member is installed so that the lower end sides of the side piece 30b can be connected, and both the ends are fixed to the excavation surface.

摘要： PROBLEM TO BE SOLVED: To provide a method capable of removing bedrock reinforcing members relatively easily without using a pipe body of special structure. SOLUTION: Members shown in the form of H are arch type supports 50 to be installed along the internal surface of a tunnel, and a support 501 is installed right in front the present face 521. An outer steel pipe 24 is driven into a bedrock D inclined at a specified angle from a lower side to an upper side of the support 501. The outer pipe 24 is provided with a third terminal pipe 24e such that the rear end side slightly projected from the face 521. First to third terminal pipes 24c to 24e are provided with fitting sections 25 at places corresponding to their respective portions to be removed. The third terminal pipe 24e is drifted from the fitting section 25 by applying vibration and impact to the end section of the third terminal pipe 24c projected from the face 521 by a breaker or the like before being excavated forward from the present face 521.
