Star Trenchless Solutions operate a modern and comprehensive fleet of pipe jacking equipment capable of installing pipelines ranging from 700mm to 1500mm in diameter
The basic concept of pipe-jacking is well established, and is capable of installing concrete and steel.
Powerful hydraulic jacks within the drive shaft are used to push the jacking pipe through the ground.
A steel tunnelling shield at the head of the pipeline is used to provide support for the excavation process and to provide directional control for the pipejack. Excavation techniques cover a wide range, from simple hand mining to backhoe and roadheader machines through to sophisticated full face earth pressure balance shields.
An accurate alignment is maintained by following a laser set to line and grade. The shield is steered to the laser line with adjustments made to the on-board steering jacks.
