Confining volume supplying device for forming tunnel`s reinforcement wall, has guillotine system, placed near filling nozzle to obtain reinforcement wall, to selectively open and close communication between feed pipe and confining volume
摘要
<p>The device has a connecting duct (81) placed between a filling nozzle (37) and a feed pipe (38). The duct is connected with the pipe that is to be supplied with masonry material e.g. concrete. A guillotine system (82) selectively opens and closes the communication between the pipe and a confining volume, through the duct. The system is placed near the nozzle for obtaining an inner reinforcement wall (83). An independent claim is also included for a method of supplying a confining volume.</p>
