GRUNDOSPLIT Pipe Splitting Tooling

Effective Pipe Splitting Methods

TT Technologies hardened heat-treated steel cutting blades are available for splitting and replacing plastic service and main lines from 1/2-inch to 4 inches in diameter. The blade designs were developed by working directly with utilities to create optimum splitting head configurations. For service line and main line splitting, the splitting heads are paired with a Grundowinch cable pulling system or other cable pulling device.

Typical Set-up

Trenchless Pipe Splitting for Gas and Water Services & Mains

During the process, small launch and exit pits are dug at either end of the service or main line being replaced. A winch cable is rodded from the exit pit, through the existing line, to the launch pit. The splitting head configuration is attached and then pulled through the existing line with a Grundowinch cable pulling system or other cable pulling device. The new service or main is pulled in behind the splitter head configuration.

Typical setup for GRUNDOSPLIT Pipe Splitting Tooling

WARNING – Plastic pipe splitting assembly must not be pulled with backhoe during splitting operation.
