They are used both as special foundations in the case of new construction on poor quality soils and for consolidation of foundations that have suffered subsidence and injuries. A different application are the bulkheads of micropiles, cantilevered or tie rods, to support excavation faces. The micropiles can be arranged on one or more straight lines or in quincunx (staggered mesh). The executive phases of the micropile can be schematized as follows: 1. positioning of the machine on the drilling point; 2. drilling the hole (with tools such as down-the-hole hammers, propellers, three-cone, triple-blade, etc. depending on the characteristics of the ground); 3. installation of the metal reinforcement (metal pipe, metal profile); 4. jet pressure of the cement in the mixture (water-cemento425, A / C ratio 0.5, with 8 q.li cement / m3, or with specific grout to be micropile) is very important that the jet of pressurized mixture (high or low) so that any debris fallen between the reinforcement and the wall of the hole can escape and guarantee the continuity of the jet around the reinforcement. In the event that the forum is not self-supporting, VE.I.CO.PAL. however, it is able to create the micropile with one of the following technologies according to the characteristics of the soil: • coated micropile (using metal coatings to be recovered at the end of casting) - any type of soil and in the presence of groundwater • self-drilling micropiles (the reinforcement pipes are used as drilling rods directly with a disposable tip and grout is injected drilling) - incoherent soils or in the presence of groundwater The company has 5 probes for micropiles and tie rods of different sizes: medium-small size (allow you to work in very confined spaces and indoor environments): n ° 2 BERETTA T43 n ° 1 FRASTE PL n ° 1 FRASTE FS40 medium-large size: (allows to create micropiles with a diameter up to 300mm) n ° 1 COMACCHIO MC800 VE.I.CO.PAL. has specialized operators with decades of experience in the use of these machines, equipped with the small diameter drill license obtained after a 40-hour course at a certified body according to the state-regions agreement n.53 of 22/02/2012. © 2013 VE.I.CO.PAL.
