5 OFT drillings under the tracks in Hoogeveen
Yesterday we completed a project in Hoogeveen, which consisted of 5 borings crossing the railroads at 3 different locations. The drillings each had a length of 15 meters Ø170 (PP). Ultimately, this is where bundles of various ProRail cables will be laid.
This drilling was also realized by means of the Pilot Assisted Method. In order to guarantee the accuracy of the drilling, a so-called "pilot drilling" is first performed by pushing a pilot rod to the desired exit point. The final casing then follows the pilot and aligns exactly with the original trajectory of the pilot bore. The difference in diameter between the pilot rod and pipe is bridged by a reamer. Pilot-driven auger drilling is suitable for drillings that require minimal deviation.
