Description

[Detailed Description of the Invention] [Field of Industrial Application] This invention utilizes existing single-track or double-track rails when repairing the inner wall surface of a tunnel, and repairs the inside of the tunnel during times when trains are not running. The present invention relates to a tunnel repair method in which the wall surface is cut and a lining plate is installed, and its equipment.

[Prior art].

Traditionally, when repairing the inner wall of an existing tunnel, the inner wall of the tunnel was first cut by manpower using a rock drill during a short period of time when trains were not passing through at night, and then the inner wall of the tunnel was shored. The cut surface is finished by either supporting the tunnel with a lining and placing a lining between the supports, or by spraying concrete on the inner wall surface of the tunnel after cutting.

[Problem that the invention seeks to solve]

However, when lining the tunnel by supporting the inner wall surface with supports, it takes a long time to perform the lining work between each support, which is not preferable when the work is performed during short periods when trains are not passing.

In addition, when concrete is sprayed, there is a problem in removing flying debris, and it is not preferable to perform the work in a short period of time.

Claims (2)

[Claims] (1) The traveling type temporary frame installation device 15, the traveling type tunnel inner wall cutting machine 6, and the traveling type lining plate erecta 11 are arranged in series in the tunnel, and the traveling type tunnel inner wall cutting machine 6 is started from one end of the tunnel. The aging tunnel wall surface is cut and removed by a certain thickness, and immediately after that, the traveling lining version erecta 11 is removed.
The lining plates are sequentially attached to the wall surface after cutting, and when a train passes, the traveling type tunnel inner wall surface cutting machine 6 and the traveling type lining plate erector 11 stop their respective operations and retreat outside the tunnel. A tunnel repair method characterized by supporting a cut wall surface to which a lining plate has not yet been attached by a temporary frame installation device 15. (2) A bendable support arm 3 is attached to a traveling bogie 2 placed on a rail 1 in the tunnel so as to be able to rotate freely around the inner wall of the tunnel, and a hopper 4 is provided to receive cuttings falling from the inner wall of the tunnel. A cutter drum 5 mounted on the support arm 3 and rotated by a cutter drive device is attached to the tip of the support arm 3 to constitute a traveling tunnel inner wall cutting machine 6. A lining plate mounting section 9 that places a large number of lining plates 8 on a traveling trolley 7 placed on a rail 1 in the tunnel.
, a lining plate installation device that supports the lining plate 8 and installs it on the tunnel inner wall surface, and a lining plate transfer device that transfers the lining plate 8 on the lining plate mounting section 9 to the lining plate installation device. 10 is installed,
A traveling type lining plate erector 11 is constructed, and a temporary frame 13 is supported on a traveling trolley 12 placed on a rail 1 in the tunnel in front of the traveling type tunnel inner wall cutting machine 6 to cut the inside of the tunnel after cutting. A tunnel repair facility characterized in that a temporary frame installation device installed on a wall surface 14 is mounted to constitute a traveling temporary frame installation device 15.
