Full Length Corrugations & Lapped Joints for More Effective Stiffness & Ring Compression. Contech 2-flange Liner Plate provides optimum shaft stability and protection when constructing new utility tunnels, relining structures under highways and railroads and lining vertical shafts. Contech 2-flange Liner Plate offers the highest continuous ring stiffness and high compression joint strength. 2-flange Liner Plate has effective stiffness that is more than twice that of the same gage (thickness) of 4-flange Liner Plate. 2-flange Liner Plate provides corrugations extending through the lapped longitudinal joint. When assembled, this liner functions as a corrugated pipe with continuous circumferential corrugations. The result is more effective corrugation performance for the highest stiffness and strength in the industry! Strength to handle the inconsistencies encountered on a regular basis. Extra safety factor when you need it most! Stiffest plate available - Usually does not require ring-beam stiffeners Available in black (uncoated) or galvanized steel - Unsurpassed in strength and safety Liner Plate for Vertical Shafts Vertical shafts vary in diameter from a few feet to 50+ feet, and frequently have depths exceeding 60 feet. Whether microtunneling, slip-lining, and installing tunnels, maintaining shaft integrity requires a dependable support system. Our Liner Plate is unsurpassed in strength and safety. Once tunneling is completed, the liner plate is often dismantled and reused. Liner Plate for New Utility Tunnels and Enclosures During tunnel construction, slough-ins and other concentrated loads are unpredictable and can be catastrophic without adequate protection.
