Background

TTC Auger Boring School (ABS)

TTC ABS is the first of short specialty schools developed by the Trenchless Technology Center (TTC). Its purpose is to educate contractors, engineers, managers, foremen, public utility personnel, etc. about this trenchless construction method. The school was held for the first time in October 2015.

The initiative came from Dr. Tom Iseley, who returend to the TTC in 2014 after nearly 20 years. He promptly initiated the development of this school to help the industry and meet the demand for professionals competent in this method design and application.

A total of 22 students attended in 2015. See the article in the Underground Construction Magazine December 2015 issue Inaugural TTC Auger Boring School Impresses Attendees.

The ABS will continue to be offered approximately once annually..

Horizontal Auger Boring (HAB)

Auger Boring is today well established and perhaps most common trenchless application. This method has been around for 80 years. It started in the 1930s in the coal mining industry. The first boring machines were built by CRC-Evans Pipeline International from rear ends of old trucks. The method was formally developed in the 1940s by Vin Carthy, Salem Tool Company, and Charlie Kandal. Charlie Kandal founded the Ka-Mo company, which manufactured the Ka-Mo horizontal auger boring machines. The early machines were powered with electricity, but later models were gasoline powered.

Salem Tool Company and Ka-Mo dominated the HEB business until 1961, when pipeline welder Al Richmond started manufacturing small HEB machines. Richmond’s machines utilized Ka-Mo augers and cutter heads until 1967. At that time, Richmond started building his own auger and cutter heads, which were similar to those of Ka-Mo. Richmond continued advancing the equipment design to keep pace with the changing market. Roy Woodruff and Son designed the split machine and also put a spacer in the 36-inch machine to make it a 48-inch machine.

In the 1960s, Ernie Coppica, Wixom, and Michigan invented a steering system.

In 1970, Leo Barbera left Richmond Manufacturing and founded American Augers. American Augers started by building hydrostatic drive machines with a built-in slip clutch.

In 1990s, Robbins Company developed Small Boring Unit (SBU), a specialized rock-cutting head used in conjunction with the auger boring machine to cut rock.
