摘要： PROBLEM TO BE SOLVED: To facilitate the positioning work by providing a positioning dish to receive a lower end of a reinforcement to be attached on an engagement part where a vertical reinforcement is inserted in first and second frames one end of which is openable/closable, and fixed by bolts. SOLUTION: A body of a reinforcement attachment jig 50 comprises a reinforcement engagement part and a holding part. End parts 51a, 52a on one side of first and second frames 51, 52 are turnably, screwed by a pin 53 in the direction of the arrows J, K, and end parts 51b, 52b on the other side are inserted in first and second pin holes 51c, 52c in an attachable/detachable manner by a fixing pin 51d. A reinforcement pressing bolt 56 provided with a bar handle 56b to press and hold a vertical reinforcement 10 by a cloth-reinforced rubber belt attached to the inside of the second frame 52 is screwed into a bolt hole 56a provided in a top part 51d of the first 51. A horizontal first reinforcement positioning dish 59 on which a lower end of the vertical reinforcement 10 is loaded, is formed on an upper end side of the second frame 52. The positioning work at the lower end of the reinforcement to be attached can be easily and simply performed.

摘要： PROBLEM TO BE SOLVED: To provide a lining device for tunnel capable of performing prompt traveling between a lining process and a process before and behind the process without having any interference with other working machines in a small cross- section, and of attaining highly efficient work. SOLUTION: A projection lining material obtained by kneading a lining material with an accelerating agent is projected in the diametrical direction from the central position of a tunnel, and a body 1 forming a lining layer in a circular-arc shape in a tunnel wall surface is supported through an inclining arm 4 on a frame 2 having a storage space for other working machines at its central part. Its inclining arm is connected to a slider 3 mounted on a frame so as to move fore and aft. In the case of use, the slider is moved forward to dispose a main body at the central position of the tunnel by an inclination arm protruding forward from the front surface of the frame. In the case of no use, the slider is moved backward to shelter the body to the tunnel wall surface side near the frame.

摘要： PROBLEM TO BE SOLVED: To accurately install and connect horizontal reinforcement without requiring skill, eliminate troublesome operations, and enhance the efficiency of connecting work. SOLUTION: This jig has a frame 21, and a jig support member 25 is provided on the frame 21 in such a way as to be freely locked to existing horizontal reinforcement 11 via an engagement support part KS, and the frame 21 is provided with an anti-turnover member 29 in such a way that time member 29 is freely engaged with vertical reinforcement 10. Further, the frame 21 is provided with a plurality of reinforcement support members 23 which are arranged above the jig support member 25 and in the vertical direction along the frame 21, and a reinforcement support part TS on which the horizontal reinforcement 11 can be placed is formed in each reinforcement support member 23.
