The application of down-the-hole drills in slope treatment projects

新闻 72 次
In slope governance—vital for project safety and ecological environment—down-the-hole (DTH) drills play a key role in slope anchoring and drainage hole construction. Slope governance requires drilling numerous anchoring and drainage holes on unstable slopes.down the hole drilling rig

 

DTH drills can operate on slopes with different gradients and rock conditions. They drill 90-150mm diameter anchoring holes—ranging from several to tens of meters deep—to install bolts or cables, enhancing slope stability.

  1. Drilled drainage holes effectively drain accumulated water in slopes, reducing pore water pressure.
  2. This drainage prevents slope landslides by minimizing hydrostatic pressure risks.
  3. DTH drills’ flexible mobility and strong drilling capacity boost construction efficiency and quality of slope governance projects.down the hole drilling rig
