Pipe Bursting
Pipe Bursting
Trenchless and Non Invasive
Pipe Bursting is the ideal technique to use for the rehabilitation and replacement of utility lines such as gas, water, sewer, telephone, and power. Pipe Bursting efficiently bursts clay, concrete, cast iron, and PVC pipe. Pipe Bursting is the ideal technique to use for the rehabilitation of ageing utility systems located in congested areas such as municipalities, city centers, and manufacturing or industrial plants for several reasons. The process is trenchless and involves very little disturbance caused by open trench excavation. A constant-tension winch guides the pipe bursting tool through the host pipe. The rear expander displaces host pipe fragments into the surrounding soil, while the tool pulls in the new polyethylene pipe. In addition, this process generally costs less than the conventional replacement through the open cut method.
Pipe Bursting
The Process
- Pipe bursting involves using a winch to pull a heavy duty polyethylene pipe through an old pipeline of equal or smaller size.
- The old pipeline is shattered using a high-powered tool with special bursting heads that smash through the old pipe while pulling through the new replacement pipe.
Pipe Bursting
- When pulled into the old pipe, the bursting head breaks the pipe into pieces, enlarges the hole and pushes the fragments into the surrounding soil. This limits pipe bursting to pipes that can be fractured and to soil conditions that will absorb the old fragments.
