Casing Advancer System Applications

Casing advancement systems can be used in a wide range of applications where you need to drill in difficult ground conditions. The following are examples of the most common applications.

Geothermal well drilling
Geothermal heating of houses is increasingly popular due to both economical advantages as well as environmental concerns. Casing advancement systems are often used to drill the holes through the overburden, keeping the hole open during installation of the heat exchange system and minimizing the impact on surrounding structures.

Water well drilling
Water well drilling is common in urban, developed areas where the well must be drilled quickly with minimum impact on the surroundings. Atlas Copco offers a solution that can be used with small, compact rigs (using the DTH drilling method) with excellent results in almost any ground condition.

Pipe roofing
Pipe roofing is a method to pre-reinforce the ground ahead of a tunnel face to ensure that excavation can proceed safely. A steel casing is installed in an umbrella pattern around the excavation line, forming a protective arch under which the tunnel can advance.

Foundation work
Stringent demands on productivity, high drilling accuracy, and the ability to drill inclined piles for foundation work make casing advancement systems increasingly popular for both end bearing and friction piles.

Anchoring
Tieback anchors, or ground anchors, are common all over the world. They are typically installed to provide support for slopes or other structures. They can be installed in combination with a retaining wall structure, as individual or systematic support.
