Pipe Bursting involves the breaking or splitting of an existing pipe, expanding the broken pipe shards into the surrounding soil while simultaneously pulling in the carrier line.
Advantages Of Pipe Bursting
- Reduces emissions and carbon foot print up to 90%
- Follows existing utility path
- No need to move surrounding utilities
- Reduces excavation costs up to 90%
- Ability to increase the size of the existing service
- Environmentally friendly with minimal surface disruption
- Reduces social costs and traffic disruption
- Extremely fast with most bursts taking only 1 to 2 days, which turns into accelerate project completion time
- Less design time and service relocation costs
A launch and burst pit are excavated to reveal the existed line. Once the burst pit is leveled the static bursting machine is lowered into the pit.
Once the machine is positioned rod is then pushed through the existing pipe. Rod payment can be pushed out at just over an hour for a 100 meter burst. Rods can easily run through sweeping bends and blocked pipe.
Bursting blades or ductile slitters are attached to the end of the rod. Pipe is attached to an expander which is attached behind the bursting blades or slitter.
During the pullback the old pipe is fractured or split and pushed out into the surrounding soil. The expander and new pipe are simultaneously pulled directly behind the bursting blades. A 100 meter burst takes less than 2 hours.
