Abstract (en)
Prefabricated liner plate (10) for lining the interior of a suberranean tunnel as a primary lining. The liner plate is formed in such a manner that the outer arcuate face (14) has a depression (12) formed therein so that a filter (16) placed in said depression permits water flow therethrough, but prevents the passage of surrounding soil particles therethrough. Suitable conduit means allows any water which may pass through the filter to be bled through the liner plate and led out of the tunnel.
