Down-the-hole drilling rig for airport runway foundation construction

News 37 Views
In airport runway foundation construction, quality affects aircraft takeoff and landing safety. Down-the-hole (DTH) drills play a key role in runway foundation drilling, where strict demands exist for drilling depth and precision.down the hole drilling rig

 

Airport runway foundations require treatments like dynamic compaction and grouting. DTH drills can create holes meeting design requirements under different geological conditions.

Specifically:

 

  1. In soft foundations, they drill several meters deep grouting holes for foundation reinforcement.
  2. In hard foundations, they drill 100-150mm diameter dynamic compaction holes as the basis for compaction work.
  3. Their high-precision drilling ensures runway foundation construction quality, guaranteeing stability and bearing capacity.down the hole drilling rig
