Description

Armtec Tunnel Liner Plate is a segmented corrugated steel plate system designed specifically for lining soft ground tunnels and relining existing conduits under highways and railroads. Individual plates weigh between 15 and 41 kg – light enough to carry by hand into a confined space. Plates are assembled into continuous rings, advancing tunnels in 500 mm long segments. Tunnel Liner Plates can be completely assembled from inside the tunnel and grouted at regular intervals. As the tunnel progresses, the liner plate continually generates ring support, providing a safe launch region for workers and equipment to advance. Features & Benefits Lightweight elements allow for simple assembly in confined spaces “Bolt from inside” workplace safety feature Small sections allow for minimal exposed excavation Can be used with poling plates, full shield or half-shield tunnel methods High seam strength bolted connections
