Pipe Ramming Services for the Toughest Ground Conditions

Capitol Tunneling has the knowledge and equipment to install steel casing using the Pipe Ramming installation method. Using our pipe ramming capabilities, Capitol Tunneling can install casings ranging from 24 to 60-inch diameter in tough ground conditions typically unsuitable for traditional auger boring or tunneling installations. Using this method of installation limits the exposure of settlement due to voids because the spoils are left inside the casing until the completion of the run. Once the casing is in place, the spoils from inside the casing are augured out to make room for the carrier pipe.

Capitol Tunneling owns and operates an 18” TT Technologies Grundoram “Goliath” hammer with collets and casing adapters in the 18”, 24”, 36”, 42”, 48”, 54”, and 60” diameters. Do you need us to go larger? That is not a problem because our crews have extensive experience utilizing TT Technologies 24” Grundoram “Taurus” hammer.

Recently, we successfully installed 200 feet of 60” diameter steel casing under the Little Miami River in Greene County, Ohio, a river that is protected under the laws of Ohio and designated as a Scenic River. We utilized our 18” hammer for the first 120 feet, and then brought in the larger 24” hammer to finish the run. Our 18” hammer also recently installed 165 feet of 54” steel casing on the Dry Run Sanitary Sewer Project for the Cincinnati Metropolitan Sewer District. The loose sand and gravel material made auger boring a risky installation under a busy road. The pipe ramming crews showed up and installed the casing with no incidence of settlement and installed the casing on line…on grade…and on time.
