Pipe ramming is ideal in adverse soil conditions in Riverside, CA.—such as gravels or cobbles—where directional drilling is not feasible. Pipe ramming uses a pneumatic powered tool to drive a steel pipe horizontally into the ground.
The front end of the pipe is left open, allowing soil to enter the pipe. After installation is completed, the soil is removed by doubling up the casing or auguring out.
Summary of the pipe ramming process:
Rammer and first pipe section are lowered into the starting pit and placed on a fabricated launch platform.
The tool is firmly secured to the pipe ensuring that full impact is transmitted to the pipe.
Rammer is connected to a conventional air compressor and the section is driven—similar to driving a stake with a sledge hammer. This system does not require thrust support.
Once pipe section is rammed into place, the rammer is reversed out of the collets, collets are removed and a second section of pipe is welded squarely into place and rammed in. Process is continued until the bore is complete.
Soil that has accumulated within the pipe is removed by using an auger or pressure plate through which compressed air or water can be fed, forcing soil out and leaving a cleanly installed steel casing, ready to house services.
The Eveready Advantage in Riverside, CA
Reduce costs- Cuts down on set-up time, reduces equipment costs
Effective in tough conditions- Ideal in cobble and sand conditions and where casing is installed near existing road services
Eliminate voids- Pipe ramming does not remove material until after the casing is installed, eliminating the risks of voids in sand conditions
Variety of sizes- Hammers are available in 12″, 16″ and 20″ and can install up to 60” diameter casings
