Atlas Copco Ground Engineering Products Unigrout grouting platforms Unigrout Flex concept
Unigrout Flex concept Since 1921 Atlas Copco is committed to grouting. Unigrout is a complete range of grouting platforms. Always ready for immediate use and dedicated to high-quality grouting. Loyal to Atlas Copco promise to increase your productivity, Unigrout Flex concept is a new step ahead in creating high performance units in a compact design. Powered either by electric or diesel all-hydraulic power packs, Unigrout Flex creates a new standard in versatility at lowest total operational cost. Higher mobility Unigrout Flex concept grouting units are characterized by a compact design. They are always mounted on small, steel platform, always equipped with slots for forklift and lifting eyes. This means reduced transportation cost and easier job-site mobilization. In fact Unigrout Flex can be used even in confined area such as urban or underground operations Easy to handle, Unigrout Flex-E High tech grouting starts with high quality cement mixing Superior by design Atlas Copco Cemix is a high speed and high shear mixer of colloidal type which grants a superior quality in your grout. In fact Cemix is able to separate and effectively wet all and each cement particle thank to its three steps shearing actions: First in the vortex in the container, created by the high velocity impeller; Second from the shearing action created by the turbulence in the specially designed mixer housing; Third, through an eccentric formed vortex to increase the shear forces; this also keeps the dry unmixed particles from forming a floating clod in the centre. The water/cement ratio you need When compared to a paddle mixer, Cemix 203 H can reach a water / cement ratio down to 0.35, producing a thoroughly uniform mix, free from lumps or aggregates. Cemix 103 H is a high speed and high shear paddle mixer of colloidal type for mixing water / cement ratios down to 0.32. Also this mixer produces a uniform mix free from lumps or aggregates. Ready for advanced admixtures Cemix is also more advantageous to use in those cases where the mix contains bentonite. Cemix can be used with micro-fine cements and with all the advanced mixtures containing fluidificants or accelerators or retardants. Grout always available Atlas Copco Cemag agitator serves as intermediate vessel between the mixer and the pump and it ensures that grout is always kept available for the operation when grouting and mixing is being Cemix mixer carried out simultaneously. Also Cemag creates quality grouting, by means of counter currents in the agitator s vessel, which keep the mixture in suspension and release air bubbles.
Efficient and versatile power units Unigrout Flex grouting platforms are operated by fully hydraulic power units, with electric or diesel drive. A variable hydraulic piston pump feeds the grout pump, Pumpac, for easy independent control and setting of grout flow and pressure.two hydraulic gear pumps feed respectively Cemix and Cemag. This configuration assures an efficient energy utilization and an easy maintenance. On the front side of the power unit is the operators place with electric cabinet and hydraulic controls for all units. A water / oil cooler is mounted in the return line before the tank mounted return filter. The hydraulic tank is provided with filler cap with breather and control level with a temperature gauge, and motor cut-out switches for low oil-level. Fully hydraulic diesel driven power unit At the heart of the system: Atlas Copco Pumpac grout pump Pumpac is the most modern grout pump in the Atlas Copco range. Pumpac features a robust design, based on a single cylinder, double acting piston. A wide range of applications Pumpac is capable of pumping most grout mixtures used for sealing and reinforcement of rock, soil and concrete. Interchangeable cylinders can vary the pressure/flow configuration, expanding the pump s application field. Independent pressure and flow adjustment Pumpac allows to adjust pressure and flow independently and step-less during the whole grouting operation. User-friendly Easy cleaning means lower operational costs. Pumpac can be disassembled with just only one 46 mm wrench. Pumpac runs on environmental friendly hydraulic fluid Pumpac grout pump Operational cost kept to a minimum Pumpac is build with best abrasion resistant material and features a smart, modularized design which reduces maintenance and operation costs lasting. Pumpac displays a self cleaning cement fluid end and features a water flushing system on the cement and hydraulic piston rods. Simple but reliable ball valves are easy to clean and last longer. Grout cylinder Ø6" (150 mm) Grout cylinder Ø4 1 /3" (110 mm) Grout flow 0-53 gpm (0-200 l /min) 0-32 gpm (0-120 l /min) Low pressure 29-145 psi (2-10 bar) 29-145 psi (2-10 bar) Pressure High pressure 116 798 psi (8 55 bar) 116-1450 psi (8-100 bar) Table of Pumpac grout flow and pressure Pumpac can be pre-set to stop at two different pressure levels. This is particularly useful whenever using tubea-manchette or other sequential grouting. methods. 3

Logac computer based recording system The Atlas Copco Logac system is a computerised logging system for sampling and storing of data during grouting or similar operations. The Logac G5 is the latest version, characterized by improved reliability and simplicity in operation. Logac mounted inside containerised Unigrout All the grouting parameters under control The Logac G5 stores and displays all of the key parameters involved in high quality grouting such as pressure, flow, volume and time. Logac G5 can monitor up to 4 lines (holes) at the same time Can-Bus architecture Logac G5 features a modern Can-Bus architecture, the same mounted on all Atlas Copco computerized drill rigs. Therefore it is more robust, easier to use, more reliable and easier to service. User friendly An 6,5 high intensity, alpha-numerical display allows a simpler identification of the holes and an easy reading of the data. Logac G5 can be interfaced to Atlas Copco Can-Bus controlled drill rigs and their measure-whiledrilling functions. A lithium, long life battery grants that no data gets lost even in case of power loss. GIN and Lugeon also available Logac G5 is capable of monitoring four grout lines simultaneously and can be used for injections using the GIN method or for Lugeon tests. The recorder registers as standard up to 1450 psi (100 bar) pressure and 26 gpm (100 l/min) flow. The recorder electronics are built-in in a tight cabinet with an LCD display. On the bottom of the cabinet there are cable connections and a USB port with a strong and waterproof cover with an easy grip to open and insert the provided USB memory stick. All data stored in the Logac G5 can be transferred to a computer, either via the USB memory stick or via a computer network connection. Logac on your Personal Computer The PC based Logac Monitor program is a part of the Logac system. It is intended for quick and easy viewing of the recorded data. Logac Monitor has three different main windows, each one associated with one of the three different injection methods: standard grouting, GIN and Lugeon for waterloss measurements. CFP flow and pressure sensors Mounted on the pressure lines, the CFP-4 operates with a pressure up to 580 psi (40 bar) and the CFP-10 up to 1450 psi (100 bar) pressure. The electromagnetic flow meter has two inductive sensors enclosed in a ceramic housing. The flow meter is without internal moving or extruding parts and has well protected integrated electronics for safe operation. The standard flow meter operates in a range of 26 gpm (100 l/min).
