Atlas Copco Overburden Drilling Systems As much as 90% of the land surface of the earth is covered with loose, unconsolidated material such as soil, clay, silt, sand, gravel and boulders, which varies in depth from a few centimeters to hundreds of meters. Drilling through this so-called overburden is often problematic, due to the tendency of the earth to cave in behind the drill. This makes it difficult to retrieve the drill string after the hole has been drilled. n practice, the bore hole is often lost before a casing tube can be inserted to support it. The Symmetrix range of overburden systems represent the latest technology in simultaneous casing advancement. Drilled piles were first used in taly, when repairing and reinforcing foundations of buildings that had been damaged during World War. Drilling was originally done with rotary drill rigs and tools were pipes with cutting teeth at the lower end. Pipes were rotated and pushed into the ground while circulating bentonite-water slurry as a mud. Over the years the engineering has improved and new equipment and technologies developed. With the introduction of percussive methods, it became possible to penetrate all kinds of soil and rock. n the early 90s, the DTH method was used above all for well. Well drillers had continuous problems with drill s making work slow. When the drill hit a boulder it might cause deviation from direction. n addition the holes in overburden tend to collapse before reaching bedrock. Then a new casing system, namely Symmetrix, was invented in inland. Until the time the was done with asymmetric drill s, but the new invention was a symmetrical drill system, which advance a casing pipe simultaneously when the hole. 3

The Symmetrix system Symmetrix is a patented system comprised of an ingeniously simple concentric method of through overburden with casing. Symmetrix drills straight holes, in any type of ground conditions, at any angle and to depths beyond 100 meters. The three main components of the system are made up of: A pilot that drills away the center part of the hole and guides the drill string. The pilot is attached to any common DTH hammer shank or top hammer rod thread. A welded to the casing pipe which is pulled down by the impact of the hammer and pilot. A symmetrical ring that is locked onto the pilot drills the void for the casing to advance down the hole. There are three different types of ring and casing shoe assemblies; A solitary ring with no connection to the. Welding ring (optional) A that holds the ring and casing shoe together. A factory assembled with integrated ring and. a) Symmetrix system with a solitary ring snd an optional. Drilling in overburden Casings are installed into the overburden basically for two different reasons: 1. To create a conduit through the overburden for example; gas, oil, water and geothermal wells utility lines starter casings for exploration grouting casings 2. To create foundation and support structures such as; piles forepoling, pipe roofs ground stabilization anchors Depending on the use of the casing it is either left in the hole permanently or retrieved by pulling out. Symmetrix range includes systems for both permanent and retrievable casings. n case of the permanent casing the ring is sacrificed and left in the bottom of the hole, while retrievable casings all system components are retrieved for re-use. b) Symmetrix system with a ring set; an integrated ring and casing shoe. 4

Permanent or retrievable casings Pile types in foundation oundation piles are generally divided in two different types, end bearing piles and skin friction piles. End bearing piles A very important factor which determines the choice of foundation and its design is formed by the geotechnical properties of the ground. 1 2 3 nstalling end bearing piles 1. Casing 1 is installed until bedrock. 2 3 2. Drill string is pulled out from the hole. 3. Reinforcement element is installed and concrete poured into the hole. n many cases piles can be footed in a firm stratum, such as dense till or bedrock, in which case they will get most of their bearing capacity from the base and consequently be classified as end bearing piles. Solitary ring s can be used in this type of. n case there is a special need to tie the and ring together (like cavities or soft clay in ground or where starts over water surface) the connection can be made economically by using a separate. and can be integrated in the factory. These factory assembled s are easy to use. The systems are available through the whole product range the smallest being for 114 mm (4 1/2") casing and largest size available at the moment is for 1220 mm (48") casing. 1 2 3 nstalling skin friction piles 1. Casing is installed. 2. Drill string is pulled out from the hole. 3. Reinforcement element is installed and concrete poured in. inally the casing is pulled out with. Skin friction piles Where there is no particular dense underlying stratum, the bearing capacity will depend on the friction forces that are mobilized along the length of the pile. These piles are called skin friction piles. Casings are often retrieved after reinforcement structure has been installed.skin friction piles can be drilled with the solitary ring as above, pulling out the casing after the concrete is poured in, but more common is to use a system where also the ring is retrieved. Such systems always have large ring inner diameters to allow maximal inside diameter usage for reinforcement structure. The same method can also be applied to well for where casings are retrieved. Retrievable systems are available for casing sizes from 89 mm to 1220 mm (3 1/2" to 48"). 5

Common system requirements Large pass through inner diameter There are casing where the passage through the ring is essential. Such requirement is typical in both piling as well as in well. Symmetrix product range includes models taking this requirement into consideration. n piling a large pass through ring inner diameter is normally required to drill a hole for a rock socket without the casing with a DTH. On the other hand the structure of pile reinforcement placed into the casing requires a certain space and when casings are retrieved ring inner diameter needs to be large enough. n well the casing is drilled through overburden into the bedrock and then the of rock well is continued with a DTH. or that reason the ring inner diameter needs to be large enough. 1 2 3 System with large pass through inner diameter 1. Casing is installed until bedrock. 2. Drill string is pulled out from the hole. 3. Drilling of the well continues with a DTH, which passes through the ring. Systems with drill-through pilot Sometimes it is economically reasonable to drill the hole for the rock socket with the actual Symmetrix pilot. This applies to all cases where the rock socket length is short compared to the casing length. By utilizing the Symmetrix pilot for the rock socket, time is saved, since there is no need to replace the Symmetrix pilot with a DTH between work phases. Symmetrix product family has such drill through systems for both permanent and retrievable casings. Drill through systems are available for most casing sizes. n the product designation code, not only the ring inner diameter, but also the outer diameter of the pilot is given since the pilot makes a larger hole than the ring s inner diameter. 1 2 3 System with drill-through pilot 1. Casing is installed until surface of bedrock. 2. Drill through pilot is unlocked from ring and after that pilot drills a rock socket. Drill string is pulled out from the hole. 3. Reinforcement element is installed and concrete poured into the hole. 6

Common system requirements Heavy-duty systems Symmetrix product family includes the heavy-duty system, which has very strong striking and pulling surfaces. n horizontal the friction between soil and casing can grow very high and Symmetrix heavyduty drill s are designed to stand the abrasion in such conditions. 2 Heavy duty system - horizontal 1. Casing is installed through overburden layer. 2. (and with starter casing) are recovered from receiving pit. Drill string is withdrawn to starter pit. 1 These systems are intended for break through where the ring is recovered for re-use. System can be also used for deep vertical holes, if there is no requirement on a large ring inner diameter. Heavy duty systems are available for casings from 140 mm up to 1 220 mm (5 1/2" to 48"). Symmetrix heavy-duty system with a solitary ring, which can be connected to a by optional. 1 Top hammer systems While most of casing is done with DTH hammers there are also requirements to drill casings with top hammers. Symmetrix product range naturally consists models for both permanent and retrievable casings with top hammer. 2 Top hammer system for permanent casings, e.g. for forepoling 3 orepoling with top hammer 1. Casing is installed. 2. Drill string is pulled out from the hole. 3. After grouting installation is finished. Top hammer system for retrievable casings, e.g. for anchoring 7

Special system designs Clay face design Sometimes clay makes casing advancement very problematic. Clay cannot be drilled with impact as its elastic structure does not break nor produce any cuttings to be flushed out, making penetration very slow. Hard, rubber type clays can be drilled with cutting only. or that reason Symmetrix clay face has been designed. Symmetrix clay version, which is optional for all models, has despite its large clay cutting face area enough surface with tungsten carbide inserts to allow also into solid rock. Clay cutting edge Sensitive conditions When facing sensitive conditions, such as underpinning and construction close to existing structures, pilot s with extra deep face flushing grooves can be of great use. These Symmetrix pilot s are used with long ring assembly to keep flushing within the face area and collect the cuttings back into the casing. This means less disturbances for surrounding structures. The method can also be utilized in marine constructions, where this assembly ensures controlled and cuttings removal in sea bottom conditions. This system does not only keep the flushing under control but also allows accurate and straight penetration in steeply sloped bedrock face. Extended ring Deep flushing grooves These two models are not included in product listing and are available on request. Please contact your local Atlas Copco customer center or distributor. 8

Special system designs Symmetrix features Each Symmetrix system is made from high quality alloy steel, and has been precision machined to produce a perfect body, heat treated to the required hardness, and fitted with durable tungsten carbide buttons. with hemispherical buttons Ballistic buttons for specific conditions Symmetrix drill s are manufactured with hemispherical buttons, but can be dressed also with ballistic buttons for use in soft and medium hard formations to achieve higher penetration rate. Ballistic buttons are efficient in cutting clay and also able to penetrate into wood when drilled within old wooden foundation. Drill s with ballistic buttons are available on request. Please contact your local Atlas Copco customer center or distributor. 9

How to select a Symmetrix system When selecting the right Symmetrix casing system, the first question to ask is whether the casing should be permanent or retrievable. This will influence the further choices. The second issue to investigate is what casing size is used by determining outer diameter of the casing pipe and wall thickness. or permanent casing, both thick and thin wall casing can be used, while a thick wall casing is needed for retrievable casing. The final step is to get a good insight of the application and requirements for the system. or example what kind of hammer is used? s continued through the ring after the casing has been installed? s the horizontal or vertical? Product designation code The Symmetrix systems will be named and ed according to the casing type, casing size and ring inner diameter in both, permanent and retrievable forms.

Operating Symmetrix with DTH Torque requirement Symmetrix method needs less torque compared with eccentric systems. A drill rig should have, however, minimum torque shown for various casing sizes in the table. Rotation speed Rotation speed depends on the size of the Symmetrix and also on the formation being drilled. The rotation speed may have to be varied as the formation changes. The harder the ground or the larger the the slower is the rotation speed e.g. Casing size Minimum torque mm inch Nm lb ft 114 4 ½ 600 440 168 6 5/8 2 000 1 480 219 8 5/8 3 000 2 210 273 10 ¾ 8 000 5 900 457 18 16 000 11 800 610 24 30 000 22 130 813 32 40 000 29 500 Casing size Rotation speed mm inch rpm 140 5 ½ 35-50 610 24 8-10 Air pressure Recommended air pressure in overburden is 12 14 bars.
