Advantages AT - Casing System

The AT - Casing System is a system solution that is adjusted to customer needs

• The application of the AT - Casing System is independent of the drilling machine available on-site
• No additional equipment is necessary to install the pipe umbrella; the drilling of casing tubes, anchors, and blasting holes can be accomplished with the same boom
• Pipe umbrella drilling works can be implemented by the standard personnel under supervision of application engineers
• Simultaneous drilling and tubing
• Possible drilling with multiple booms, depending on the excavation geometry

The AT - Casing System offers a variety of technical advantages

• Higher drilling progress by using hydraulic rotary-percussion rock drills
• Flushing with water - avoidance of dust formation
• Recirculation of the flushing water inside the casing tube - protection of the surrounding ground
• Accurate alignment of the casing tubes
• Reduction of displacements by immediate support of the drill hole
• Easy extension of the casing tubes even in case of little excavation geometries or starting shafts
• Flexibility regarding the drilling depth due to extendable casing tubes with a standard length of 3 m
• The structural properties of the AT - Casing System can be fitted to the project or costumer requirements

The AT - Casing System is an efficient and technically mature product

• Time savings due to the minimization of non-productive times
• Cost reduction due to the faster creation of a complete pipe umbrella
• Practical experience over several years
