The concrete spraying device requires the concrete pump to be lowered to a low position so that concrete naturally flows down from the concrete mixer truck to the hopper of the concrete pump during spraying work. Since there are many irregularities on the road surface in tunnels and tunnels, the concrete pump must be lifted to a high position so as not to scratch the bottom of the concrete pump.
Particularly in the upper half advanced drilling method, a large departure angle is required because there is a slope connecting the lower half and the upper half. Therefore, conventionally, as shown in FIG. 4, a rear wheel 2 of the traveling carriage 1 is used.
On the rear side of the vehicle body, there is used a concrete spraying device (Actual No. Sho 62-7494) in which a base 4 carrying a concrete pump 3 is tiltably supported.
