Pipe Bursting

Designed to go inside an existing undersized or damaged pipe and replace or up size to larger (HDPE) pipe for critical grade shots (i.e. sewer lines or drainage lines). Pipe Bursting is a system used for the replacement or upsizing of existing water or sewer mains, etc. Minimal excavation is required to start the installation of the new piping behind the pneumatic pipe bursting system.

Crossings:

• Water Lines
• Sewer Lines
• Electrical Duct Formations

Applications:

• Environmentally Sensitive Areas
• High traffic areas
• Crossings - highways, roads, railways, waterways
• Crossing private property where surface restoration can be costly

Brief Process Description:

• Pneumatic pipe bursting is like driving a nail through wood with a hammer. Repeated blows progress the nail through straight and clean. Imagine trying static force only (as some bursting systems use) to "push" the nail in!
• Using a simple, effective process during the pneumatic pipe bursting procedure, the bursting tool is placed into the host pipe at an entry pit or manhole. A constant tension winch, based at the exit area pit and attached to the head of the tool, guides it through the host pipe. Continuous percussion from the pneumatic tool fractures the host pipe.
• The bursting tool effectively hammers its way through the host pipe, displacing the fragments into the surrounding soil, while simultaneously pulling the new pipe, usually High Density Polyethylene (HDPE), into place behind it. Pipe bursting is the only trenchless method of replacement that allows for the upsizing of the original pipe.
• The winch plays a key roll in pipe bursting operations. The constant tension, variable speed winch makes adjustments for conditions that affect line speed during operation, providing constant and consistent pulling force and preventing slack from developing in the line, essentially guides the tool through the host pipe.
• Several factors dictate whether pipe bursting is appropriate for the rehabilitation of a failed line. These considerations include host pipe material, diameter, condition, depth, length, new pipe diameter, soil conditions, peripheral utilities and service connections. The bursting tool can be used to burst fracturable pipes (cast iron, clay, concrete, RCP, ABS and some plastics) with diameters between 4 and 54 inches.
