きるように制御する。 An excavator main body 4 is installed on one side of the truck 1, and a rotating shaft 4a is installed in the tunnel direction. A rotating arm 4b is fixed to the inner end of the rotating shaft 4a, so that it can rotate about the rotating shaft 4a. The excavator main body 4 is installed on the truck 1 so that its rotating shaft 4a is located at the center of the tunnel having an arcuate cross section. A movable frame 4 is attached to the tip of the arm 4b.
c is attached so that it can be moved in the tunnel direction (left and right in FIG. 1) by means of a cylinder 4b. A telescopic arm 4e is attached to the movable frame 4c so that it can move forward or backward in the radial direction, that is, in the direction of the wall surface. A cutter 4f is attached to the tip of the telescopic arm 4e, and is adapted to excavate the wall surface. still,
When the cross section of the tunnel has a shape other than a circle such as a horseshoe shape, the telescopic arm 4e is operated appropriately to control the cutter 4f to reliably excavate the wall surface to a predetermined depth.

is oriented to coincide with the axis of the
It is designed to be able to slide in the tunnel direction (left and right in Figure 1). A support rod 5b is fixed to the inner end of the rotating shaft 4a, so that it can rotate together with the rotating shaft 5a. A spray nozzle 5c is attached to the support rod 5b, and a hose 5d is attached to the support rod 5b.
Concrete is pumped in and sprayed onto the wall. In addition, the above support rod 5b
rotates following the rotation of the rotary arm 4b, and can also move in the same direction as the cutter 4f is moved in the tunnel direction by the cylinder 4d.
