American Transmission introduces new method for transmission line construction
American Transmission Co. (ATC) introduced this week a new, patent-pending method for installing transmission structure foundations using a vibratory hammer.
According to the company, the method is faster, safer, more economical and more environmentally friendly than traditional installation methods used when a concrete base is not needed, such as direct bury and traditional vibratory installation.
“This new method is a game changer in transmission line construction,” ATC Executive Vice President and CEO Mark Davis said. “Solo-Driver is just one part of ATC’s commitment to excellence in transmission planning, construction and innovation, and we are excited to announce this new technology and share it
with our transmission partners.”
The Solo-Driver method uses a single excavator equipped with a vibratory hammer for foundation installation. To utilize the method, caisson foundations must be modified to include side tabs for use with the vibratory hammer. The hammer grips the tabs and uses them to lift the foundation from a horizontal position on the ground. It then rotates it vertically and into position, and finally vibrates it into the ground to the depth needed.
In optimum conditions, ATC said, the Solo-Driver method can cut installation costs by half and requires fewer works. It is also quieter than other methods and requires half the typical overhead space.
