Down-the-hole drilling RIGS for the foundation construction of port and wharf projects

新闻 84 次
In port and wharf engineering foundation construction, challenges include complex marine environments and variable geology. Down-the-hole (DTH) drills are applied here due to their reliable performance. Port and wharf foundations require pile foundation construction and seepage prevention.down the hole drilling rig

 

DTH drills can conduct drilling on offshore platforms or shorelines. They drill 100-200mm diameter pile foundation holes—tens of meters deep—in seabed foundations with different lithologies, ensuring pile construction for wharves.

  1. Drilled seepage prevention holes are used for curtain grouting to block seawater leakage.
  2. This grouting enhances the stability and durability of wharf foundations.
  3. DTH drills’ adaptability to marine environments supports efficient and reliable foundation construction.down the hole drilling rig
