Pipe ramming for challenging project

Baltazar was contracted to install casings to house new water and sewer mains under the highly travelled Route 175 in Newington, Connecticut.

According to Utility Products, Baltazar completed a utility connections project in Connecticut requiring a pipe installation method that would limit disruption due to work schedules and lane closer restrictions from the Connecticut Department of Transportation (DOT).

Baltazar Project Manager Kyle Murphy said pipe ramming was the ideal method as it allowed for a narrow pit at the four-lane, heavily travelled roadway.

“Originally, the design called for pipe jacking, but the DOT and town did not desire the road to be closed for any period of time, nor would it permit a large pipe jacking pit,” said Mr Murphy.

“The roadway needed to be completely open at the end of every day.”

Trenchless equipment manufacturer TT Technologies specified the ramming equipment for the project which was an 18 inch diameter Tracto-Technik Grundoram Goliath.

Despite the limited work schedule and project constraints, Baltazar installed the two 36 inch (914 mm) steel casings within two weeks.
