Down-the-hole drilling RIGS for dam foundation construction in water conservancy and hydropower projects

News 98 Views
In water conservancy and hydropower projects, the construction quality of dam foundations directly affects dam safety. Down-the-hole (DTH) drills play an indispensable role in dam foundation drilling. Dam foundations require operations like curtain grouting and consolidation grouting, demanding extremely high drilling depth and precision.down the hole drilling rig

DTH drills can create grouting holes reaching tens of meters deep under complex geological conditions. They use high-precision positioning systems to ensure accurate hole locations and uniform diameters. In hard rock foundations, they drill 76-130mm diameter grouting holes, guaranteeing continuous anti-seepage curtains for curtain grouting.

 

Specifically:

 

  1. These holes effectively prevent foundation seepage, enhancing dam stability and safety.
  2. The precision drilling supports the formation of reliable grouting structures for long-term durability.
  3. DTH drills’ adaptability to complex geology ensures high-quality foundation construction for dams.down the hole drilling rig
