Tunnel liner plate

Tunnel Liner Plate

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. Since complex tunnel lining equipment is not required, installation is quick and easy with minimal disruption to road users and the surrounding environment. A variety of material options and coatings are available to optimize service life requirements.


Applications

• Tunnel Lining

• Relining (rehabilitation of failing structures)

• Both Vertical and Horizontal Shafts


Features

Lightweight - Lightweight plates can be hand-carried into a confined space

Versatile - Variety of shapes and sizes available for horizontal or vertical installation

Economical - A cost effective solution for the rehabilitation of failing structures

Rapid Installation - Only two basic parts (plates and fasteners) – no special skills are required for assembly


Depth of cover

The minimum allowable depth of cover is the largest of:

For roads H=B/8+0.2(m) H=B/6(m) and not less than 0.6(m)

For railways H=B/4 and not less than 0.6(m)

There is a possibility to reduce depth of cover provided that suitable checking calculations will be made.
