Foundation work Stringent demands on productivity, high drilling accuracy, and the ability to drill inclined piles at,as foundation work make casing symmettrix systems increasingly popular for both end bearing and friction piles. Elemex — for improved air control The Elemex casing advancement system is the preferred system for minimizing the risk of settlements in surrounding strucutures.
The unique design of the pilot bit directs the air over the drill bit surface, reducing air leakage into the ground.
Water well drilling Water well drilling is common in urban, developed areas where the symmetrux must be drilled quickly with minimum impact on the surroundings.
The system adds value whether the mission is to install foundation, support elements, or simply case the hole in collapsing formation. When changing the pilot bits you only need one ring bit set for both pilot bits, and you will save time as well as money.
Symmetrix and Elemex
The system drills more quickly and accurately than any other method available today. A symmetrical ring bit. Please explore our complete range of products, all designed to help you achieve the highest possible productivity with the lowest possible maintenance costs.
New face design for Symmetrix and Elemex pilot bits improves drilling in all ground conditions. The unique design of Symmetrix provides reliable results, which saves contractors money. The three main components of the system are A pilot bit, which drills the center part of the hole and guides the drill string. Atlas Copco offers a Permanent Ring bit system for DTH drilling — Symmetrix, an all-round overburden drilling system for holes of any depth or size.
Aglas has a simple structure, good quality and the system is easy to operate.
Whether used in ground with big boulders, inclined competent layers, or hard bedrock Arlas drills until the required depth is reached. They are typically installed to provide support for slopes or other structures.
Top Hammer Drilling Tools. Improves your productivity and capability Comprehensive range of DTH hammers and drill bits to match all conceivable applications Cutting edge technology that has been tested and proven through years of field use. Besides our world class products — our success is due to our commitment to the industry, coopco interaction with customers and our commitment to sustainable productivity.
Casing Advancement Systems
Retrievable Casing Retrievable casing is used when the casing is only needed during the drilling process, that is when it is used to keep the hole open during drilling and not used as support in the finished structure. Odex systems has become the standard among drilling contractors for casing in water wells, geothermal wells and for shallow micropiling work.
When drilling in so-called overburden, the conditions are often challenging with risk for collapsing walls, hole deviations, and failure to reach design depth or bedrock. This enables contractors to perform their work wtlas with higher quality and reduced risk. Manufactured in-house, each bit is symmwtrix fitted with the required shape and sized buttons.
Casing advancement systems are often used to drill the holes through the overburden, keeping the hole open aflas installation of the heat exchange system and minimizing the impact on surrounding structures. Symmetrix can drill straight holes at any angle including horizontal and to depths beyond meters feet.
The unique design of Symmetrix provides reliable results, which saves contractors money.
The Symmetrix system is a patented, ingeniously simple system using a concentric method of drilling through overburden with casing. This is an extra advantage when sensitive ground is encountered.
Casing Advancement Systems (Symmetrix / Elemex)
Ut enim ad minim veniam, quis nostrud exercitation. It is primarily used for smaller diameter holes in overburden drilling, such as anchoring piles or micropiles. Designed specifically for pipe roofing and top hammer applications. The directed air flushing enables the driller to be in full control of the drilling process. 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.
Symmetrix – Productivity and Precision Symmetrix smymetrix a versatile solution for overburden drilling where ground conditions are difficult, time is limited, and precision is crucial. Click on casing size copck for specs, then roll pointer over or click on the table to enlarge.
Atlas Copco Geotechnical Drilling symmetrox Exploration manufactures and markets equipment needed for surface and underground exploration drilling applications. Symmetrix handles casings from 76 to 1, mm 3 to 48 in to almost any depth. Both Symmetrix and Elemex systems offer retrievable and permanent alternatives.
Retrievable system with a unique design that enables a large inner diameter. Thanks to the ingenious reaming wing, the bit is retrievable and can be used again. A casing shoe welded to the casing pipe, which is pulled down by the impact of the hammer and pilot bit.
Symmetrix and Elemex – Atlas Copco Việt Nam
Elemex is not only a safe choice where settlement of neighbouring buildings can be a risk with other methods. Secoroc DTH hammers are available in holes sizes from 3,5 to 48 inches in diameter and up to 72 inches with the Secoroc Cluster drills. Designed for deep holes where you atlws to drill shallow rock sockets below the casing with the pilot bit.
Atlas Copco Symmetrix offers a retrievable ring bit system for DTH drilling, an all-round overburden drilling system for holes of any depth or size. Atlas Copco Secoroc has a comprehensive range of DTH drill bits that have been designed to match all conceivable applications.
It is suitable to use for straight piling or well drilling that requires co;co high performance needed for drilling large and deep holes. 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.
Top hammer Top hammer drilling is a fast and efficient method for drilling shorter holes, straight or inclined. Symmetrix system drills quicker and more accurate than any other method available today. The system adds value whether the mission is to install foundation, support elements, or simply case the hole in collapsing formation. Symmetrix can drill straight holes at any angle including horizontal and to depths beyond meters.
