Khuduyane Quigley is a leading service provider with expert knowledge in the field of horizontal directional drilling which uses trenchless methods to install underground pipelines, cables and service conduits.
Trenchless Technology is widely-utilised in the civil engineering sector. The trenchless revolution share, compared to open-cut excavations, is ever increasing due to the underground installation technology and renewal of pipelines becoming ever more cost effective than the now outdated methods previously used.
These advantages are due to labour intensive excavation and re-instatement work being reduced to the absolute minimum. The advantages of less intrusive time on site is particularly noticeable when installing property service connections and crossing highly frequented roads, rivers, railways, etc.
With fluid-assisted drilling, Khuduyane Quigley’s directional GRUNDODRILL rigs first create a pilot drilling along a flexible bore path using a steerable drilling head. When the drill rods are pulled back, the borehole is upsized by an expanding head and the attached pipe is pulled into the bore path. Thereby, longitudinal bores, crossings underneath water- and other traffic-ways can be carried out even in rocky ground.
