The percussion drilling method, called pipe jacking, is used for installing pipelines under the ground without digging – for gas pipelines or protective tubes with diameters between (25-2000) mm, under railway embankments, platform lines of railway, stations and marshalling yards, national and county roads, tram depots, premises, irrigation canals, airports, bridges, etc. Mentioning that it also complies with all conditions of the STAS 9312-87.

The technology is based on advancing the steel pipeline in the ground, operated by a percussion equipment attached to its end.

The percussion device is a robust pneumatic equipment of high reliability, acting independently. The machine is equipped with modular accessories that allow adaptation to pipes with different diameters. The assembly and handling of this equipment is done with simple operations, all devices being ergonomically designed.

Main technological stages:

  • Preparing the pipeline in the launching pit
  • Laying the pipeline into the ground by percussion (pipe jacking)
  • Emptying the pipe after placement, manually or by machine

The advantages of horizontal percussion drilling – pipe jacking:

  • Does not dislodge the ground and does not cause subsidence.
  • Does not create holes or collapses during work or after execution.
  • Work performed through horizontal directional drilling method does not cause discomfort to road or rail traffic and does not jeopardize safety.
  • Shorter execution time compared to other technologies.
  • Occupying a smaller land for equipment setup and work execution.
  • The reliability of undercrossing works through the horizontal directional drilling technology is the same as the lifetime of the buried pipelines.
  • Horizontal directional drilling can be performed in almost any type of ground.
