Pipe Ramming
Pipe
ramming is a trenchless method for installation of steel pipes or
casings, in which a pneumatic tool is used to hammer the pipe or the
casing into the ground while the excess soil from creating the borehole
is removed to the surface. The method is frequently used under
railway and road embankments. When casings are installed, pipes of
other types for distribution of sewerage, water or gas, or electrical
or telecommunication cables are subsequently inserted. The method
is non-steerable.
Compared
to other trenchless methods such as augering and directional drilling,
pipe ramming can save both total installation time and costs under
favorable conditions. Installation time can often be nearly 40%
shorter than in augering because required width and depth of pits are
smaller and actual installation is faster (40 to 60 feet sections can
be rammed in half an hour while auger boring the same distance requires
half a day).
Pipe Ramming
Pipe
ramming essentially involves the ramming of steel pipe through soil
using a pneumatic devise -- rather than creating a bore hole.
Here are some thins to keep in mind for pipe ramming:
* Uses steel pipe only
* Optimum size is 4" to 60" in spans up
to 400'
* Requires a bore pit
* Can be used in many types of soil
conditions
* Since smaller diameters of pipe can
be deflected by obstructions such as
boulders or cobbles, accurate
information on soil conditions is
essential.
* The main limitation is less control
over line and grade -- so setup is
critical

L Bowen Construction is experienced and qualified in pipe
ramming. We have the equipment and the personnel to do any size
job.
We have successfully rammed all sizes of pipe. Our biggest job was successfully completed with 100' of 48" pipe.
