March 2007

In the process of updating their cement plant facilities in Pueblo, Colorado, Groupo Cementos de Chihuahua needed to construct four aggregate conveyor tunnels. The structures will enclose the conveyors that transport crushed limestone under 70’ piles.

The enclosures were originally designed as four-sided concrete boxes. After consulting with Contech, the owner accepted four MULTI-PLATE round tunnels as a more efficient and cost effective solution.

The MULTI-PLATE structures were able to support a significant amount of dead load as well as accommodate the horizontal alignment and vertical slope changes along the conveyor belt. Installation took a little more than a week, with two days of installation spent on each tunnel.
