Pipe Bursting
SPS utilized pipe-bursting technology to replace main lines and lateral quickly, with little surface disruption. Pipe bursting is the only method of trenchless pipeline rehabilitation and replacement that allows for the upsizing of existing lines.
About Pipe Bursting
There are three types of pipe bursting: static, hydraulic and pneumatic.
While static and hydraulic systems are very common, over 90% of pipe bursting in the US is done with pneumatic tools.
During pneumatic pipe bursting, the pipe bursting tools is guided through the old or "host" pipe by a constant tension winch. As the tool travels through the pipe, its percussive action effectively breaks apart the old pipe and displaces the fragments in to the surrounding soil.
As the tool makes it way through the host pipe, it simultaneously pulls in the new pipe, usually HDPE.
In certain situations, the tool may be equipped with an expander, which displaces the host pipe fragments further into the solid and makes room for larger diameter pipe.
Fractural host pipes include: concrete, RCP, VCP, cast iron, PVC, ABS plastic and transite.
