1. Understanding Pipe Bursting

Pipe bursting is a trenchless technology revolutionizing the way sewer replacement is conducted. Unlike traditional excavation methods that involve digging trenches to access and replace old pipes, pipe bursting offers a minimally invasive alternative. This technique relies on hydraulic power to fracture existing pipes while simultaneously pulling a new pipe into place. The process is facilitated by specialized equipment and requires only small access pits at the beginning and end of the pipe section being replaced.

2. The Mechanics Behind Pipe Bursting

At the heart of pipe bursting is the bursting head, a crucial component that drives the entire process. This head, slightly larger in diameter than the old pipe, is equipped with cutting blades or rollers on its surface. As hydraulic power is applied, the bursting head is pulled through the old pipe, exerting force to fracture it. The fragmented pieces of the old pipe are displaced into the surrounding soil, making way for the new pipe. Simultaneously, the new pipe, attached to the bursting head, follows the path created by the fracturing process, gradually replacing the old pipe.

The process involves meticulous planning and coordination. Hydraulic equipment is carefully calibrated to ensure the controlled movement of the bursting head and the precise installation of the new pipe. Skilled technicians oversee the operation, monitoring progress and making adjustments as needed to ensure smooth execution.
