The company has therefore developed a new technology that allows to achieve decidedly valid and reliable results, integrating the performance of expanding resins with those of self-drilling steel bars (micropiles injected with high density resins). This technology, called "Injection of Reinforced Resins" (IRA), developed on the basis of tests performed in situ and analyzes carried out at material laboratories, covered by a patent application, consists in performing localized and differentiated injections of expanding resins, using high-strength steel bars, having the double function of reinforcement and means for carrying out the injections themselves. The main characteristics and advantages of this new application can be summarized as follows: • possibility of using self-drilling bars with Ø from 32 to 51 mm, depending on the required performance; • possibility of using resins studied and developed for specific use in the civil and geotechnical engineering sector; • possibility of easily reaching the required depths, allowing the loads to be effectively transferred to undisturbed soils, not subject to the effects of seasonal climatic variations and with suitable physical-mechanical characteristics; • possibility of crossing land and artifacts of every type and consistency; • possibility of using machinery and equipment of reduced weight and bulk, thus allowing to operate even in small and / or difficult to access environments or areas; • possibility, using a single perforation, to inject resins with different characteristics (for composition, density, pressure, consistency, hardening speed) and at different times, depending on the characteristics of the work to be carried out and the conditions of the structure and 'lithostratimetric and geotechnical structure of the land concerned; • possibility of injecting, using the same technologies, also special cementitious mortars; • possibility to easily and accurately predetermine the location of the injections, thanks to the use of reliable and innovative valve-groups, integrated in the same self-piercing bar; • possibility of continuously monitoring and modulating all the injection parameters, making it possible to minimize the undesirable lifting of the structures (flooring, etc.) and / or to remedy any unforeseen problems; • possibility of connecting the existing seabed structures with the IRAs, appropriately exploiting the mechanical characteristics of the self-drilling steel bars; • extreme flexibility and adaptability of the system to the different technical and environmental needs; • possibility of developing a calculation model aimed at sizing the intervention to be carried out; • possibility of carrying out accurate and documented load tests on any IRA performed; • reduction of the costs necessary for the restoration of the sites involved in the works. © 2013 VE.I.CO.PAL.
