があった。However, with this spraying method, the lining material collides violently with the sprayed surface such as rock, causing a lot of material to bounce back, which increases material loss. There was also a safety issue as the aggregate would bounce back and rain down on the nozzle man. Furthermore, since the conventional method uses a simple spraying method using a nozzle, there is a problem in that if the ground is uneven, the finished surface becomes uneven, requiring troublesome corrections.
本発明は前記のような従来のものの不利、欠点を解消し

付けられ、壁面に付着してライニング層Ｗを形成する。However, when lining a tunnel,
The movable formwork 1 is carried into the tunnel, and the movable formwork 1 is directly opposed to the tunnel wall surface using the supporting means 3 so as to have a space 16 corresponding to the lining thickness. On the other hand, for spraying, the means is driven to force-feed the lining material W to the position of the spray nozzle 10 and add the quick-setting material. As shown in Figures 1 and 2, for spraying, set the nozzle 10 so that it faces the wall from the front side in the excavation direction, and
Start spraying inside. In narrow spaces where the nozzle does not easily hit the wall, it is desirable to use a nozzle with a bent or rotatable tip. This ensures that the entire amount of the lining material W is sprayed into the space closed by the movable formwork 1, and adheres to the wall surface to form the lining layer W.

動速度とすることができた。In the present invention, in parallel with such spraying, the movable formwork 1 is moved in the tunnel axis direction by the moving means 4, and this movement may be continuous movement in synchronization with the formation of the lining layer. However, it may be an intermittent movement in which the width of the movable formwork 1 is one cycle. The moving speed may be set appropriately depending on the degree of hardening of the concrete, but when a quick-setting agent is added, the adhesion speed to the wall surface is good and demolding becomes easy. According to experiments conducted by the present inventor, spraying could be performed at a moving speed of at least 100 m/1 nJA at a thickness of 10 cm.
