How trenchless excavation works
Pipe jacking is a trenchless method for installing underground pipelines.
The pipes are pushed through the ground using hydraulic jacks from a launch shaft to a reception shaft. This specialist construction method reduces impact and damage to our roads and infrastructures. It also reduces disruptions to local residents, businesses and road users.
The launching shaft will be excavated at the starting point where the pipe jacking machine and equipment are set up. The reception shaft is at the endpoint where the jacking process ends and the machine is retrieved.
A jacking frame equipped with hydraulic jacks that push the pipes through the ground is installed in the launch shaft. The pipe is fitted with a cutting edge to cut through the soil, and the excavated material is transported back to the launch shaft. After the initial pipe section is installed, subsequent pipe sections are added and jacked into place. Each new pipe section is pushed by the jacks, propelling the previous sections forward
