Down-the-hole drills in railway tunnel projects

新闻 93 次
In railway tunnel engineering, stricter demands exist for construction quality and progress. Down-the-hole (DTH) drills meet these needs with their excellent performance. Railway tunnels often cross complex geological areas where rock hardness and integrity vary greatly, and DTH drills can adjust drilling parameters according to different geological conditions.down the hole drilling rig

 

During tunnel excavation, DTH drills quickly create blast holes that meet design requirements. In hard rocks like granite, they drill 100-165mm diameter and 4-6m deep holes, providing an accurate foundation for blasting excavation.

Moreover:

 

  1. DTH drills are equipped with intelligent monitoring systems to real-time track parameters like hole depth and angle.
  2. The systems promptly detect and correct drilling deviations, ensuring tunnel construction quality.
  3. This precision supports the smooth advancement of railway tunnel projects by maintaining high-standard operations.down the hole drilling rig
