| Certa-Lok Restrained-Joint PVC Pipe and AXIS Guided Boring System  "CertainTeed's field-proven Certa-Lok spline-locking technology and Vermeer's AXIS guided boring system have changed the game when it comes to replacing or repairing both force main and gravity sewer systems, as well as potable water infrastructure," said John Coogan, channel marketing and communications manager for CertainTeed's Pipe & Foundations Group. "AXIS' laser-guided technology and Certa-Lok's strength and ease of assembly work together to ensure trenchless projects achieve precise grades and stay on schedule with minimal disruption to the community."In response to growing recognition of the economic and environmental advantages of trenchless pipe installation and replacement, CertainTeed recently expanded its Certa-Lok offering to include an integral bell option on its 4-, 6- and 8-inch C900 pipe. The company also added a 14-inch diameter C905 option. All Certa-Lok pipe features a mechanical joining system, which utilizes a combination of precision-machined grooves and a nylon spline to provide exceptional tensile strength in pulling or pushing operations. Rounding out the design, a flexible elastomeric gasket provides a solid pressure-certified hydraulic seal. Unlike HDPE or fusible PVC pipe, Certa-Lok pipe products do not require costly on-site fusion operations and can be assembled in real time as pullback continues, eliminating the need to string out several hundred feet of pipe within or beyond the work zone. The Vermeer AXIS laser-guided boring system is a pit-launched trenchless installation method designed to achieve pinpoint, on-grade accuracy while eliminating many of the difficult steps associated with other installation techniques. It is optimized for pipeline installations up to 350 ft. in length, which is ideal for manhole-to-manhole projects. Most importantly, it is fully capable of maintaining precise on-grade accuracy, which is critically required for gravity sewer pipe systems. A closed-circuit camera integrated into the drill head allows the operator to constantly monitor the line and grade of the bore via a laser guide. As the bore continues, displaced soil is vacuumed out through a hollow section in the drill head, eliminating the need to suspend drilling to manually handle spoil. "The need to replace and expand sewer and potable water systems presents a vast challenge and opportunity," said Jason Zylstra, marketing manager for Vermeer. "The existing network of pipelines has been stressed by population growth and urban sprawl, and much of this network is nearing the end of its useful life. Vermeer's AXIS system and Certa-Lok restrained-joint PVC pipe present a cost-effective solution for bringing the nation's infrastructure in line with current needs and keeping it strong for years to come." write your comments about the article :: © 2012 Construction News :: home page |
