Precision boreholes on various heavy civil projects.
The power of Accu-dril™ delivers solutions to multiple geotechnical applications. These may include: dam remediation, drilling holes intersecting underground tunnels for utility lines (ventilation, electrical, water and others) as well as freeze rings. When designing and drilling freeze holes for freeze rings, Accu-dril™ facilitates shaft construction in unconsolidated and water-saturated formations.
Accu-dril™ is used to steer a surface launched drill hole and turn it horizontal to conform within a desired tunnel target radius and trajectory. Once on trajectory this allows the extending hole to retrieve core samples and to achieve borehole formation water testing within the tunnel footprint. This is a desired application for pre-construction design for aqueducts and highway tunnels.
