World’s first 1.2 m casing advancement system

Atlas Copco has paved the way for new opportunities in large hole drilling with the launch of the construction industry’s first casing advancement system designed for 1.2 meter diameter holes.

Large diameter casing advancement systems from Atlas Copco’s Symmetrix range are used all over the world as an alternative to conventional piling. Now the company has paved the way for new applications for drilling contractors with the introduction of the industry’s first system for 1.2 m diameter casing.
Not only will the new casing system enable contractors to expand into new areas, it will also enable them to save time and reduce costs in large hole drilling operations.

“We are proud to be the first company to have this system size available on the market,” says Mario Andrade, Product Line Manager for large diameter casing advancement systems.“It is the perfect solution for contractors in view of the increased demand for large hole applications that require drilling with rotary percussive methods.”

Compared to conventional piling for foundation work, the Symmetrix percussive casing advancement system offers a range of key benefits. For example, it means that drilling and casing installation can be done in one single operation, which increases productivity. In addition, it combines exceptional hole straightness with a deep hole drilling capacity.

One contractor that has already benefited from the 1.2 m system is Lännen Alituspalvelu Oy of Finland. This company specializes in horizontal drilling of underpasses and has recently used Symmetrix, together with the QL300 DTH (down-the-hole) hammer, for a number of 1.2 m casing projects around the country.

Operations Manager Pekka Vepsä says:“Casing advancement with DTH hammers is a good method, especially here in Scandinavia where we have to drill through very tough, hard rock or boulders. We use it for installing 219 mm –1 220 mm casing and means that we can drill in every type of ground with good accuracy. I was particularly surprised at the good performance of the hammer in the new system which, even in our Finnish hard rock, gave excellent penetration.”

Andy Jacques, Operations Manager at Atlas Copco’s Competence Center for large hole applications, explains:“Our offer to the customer is to provide all the in-hole tools required – from the drill bit to the adapters, drill rods, hammers, drill shrouds, casing, compressors and pumps – together with technical advice on their correct use and maintenance.”

In addition to developing the Symmetrix range, Atlas Copco is also expanding its rental service. This gives contractors the opportunity to select the most efficient method of completing a contract without the capital expenditure of making a purchase. Atlas Copco says this solution is of particular interest when the cost of purchase represents a significant proportion of the revenue that will be earned from the contract. Jacques concludes:“We don’t claim to offer everything to everyone, but for those who work in large diameter applications, this is the place to find the most comprehensive range of equipment and services available under one roof.”
