CASE STUDIES


SLICK BORINGSLICK BORING• The reusable bore pipe is rammed in place

• Bentonite or polymers are used to lubricate the bore hole and the soil inside the bore pipe

• The soil is expelled from the bore pipe

• Line pipe will then be welded to the bore pipe

• The reusable bore pipe is rammed in place

• Bentonite or polymers are used to lubricate the bore hole and the soil inside the bore pipe

• The soil is expelled from the bore pipe

• Line pipe will then be welded to the bore pipe


SLICK BORINGSLICK BORING• Utilizing a sideboom tractor and winch

• The bore pipe is pulled out of the bore hole

• While the line pipe,welded to the bore pipe, is pulled into place

ON THE JOBON THE JOB• 115 ft. bore pipe was lifted into position with a

sideboom & an excavator

• Rammer positioned and supported by an excavator

• Air compressor and bentonite pump are mounted to a semi-tractor trailer for mobility

• Positioned on the right-of-way at the edge of the open ditch next to the bore pit

ON THE JOBON THE JOB• Typical bentonite or polymer application

approx. 900 gallons for a 95 ft. bore

• Ramming times varied from 30 to 60 minutes per bore

• Three bores of 95 ft. length were completed the first week

• At the week two the crew had completed five bores of 95 to 100 ft. in length and one bore 240 ft. in length
