Our durable CON/SPAN and BEBO structures can meet heavy duty demands for industrial or mining applications. CON/SPAN and BEBO structures can be adapted for use in tunnel applications or improving mine entrances. The arch shape is also ideal for supporting aggregate piles and can be designed to accommodate site specific openings and equipment requirements. Underpasses and overpasses can be designed using Cooper E-80 loading, and these prefabricated systems allow for fast installation and easily accommodate staged construction methods for busy, active railroad tracks.
Our durable Plate Structures can meet heavy duty demands for industrial or mining applications. MULTI-PLATE round arch shapes are the most widely used structures for aggregate tunnels. Special features such as hopper openings, conveyor supports, bulkheads, escape laterals and elbows to accommodate grade changes and alignment are readily integrated. Plate structures can also be utilized to extend and improve mine entrances, providing protection from falling rocks and debris.
During tunnel construction, slough-ins and other concentrated loads are unpredictable and can be catastrophic without adequate protection. Our sufficiently stiff tunnel Liner Plate functions as a safety zone for workers and equipment. The required amount of liner stiffness depends upon soils, tunnel size and construction methods.
