PIPE JACKING

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.

EXTENSIVE RANGE OF MODERNISED PIPEJACKING EQUIPMENT
we are able to offer the most appropriate machine for every scheme, based upon criteria such as diameter and length of tunnel, ground conditions and position of the ground water table.
