Works on full replacement of concrete elements of engineering constructions of different function (channels, sluices, pipelines, dams, piers, quays, etc.) are rather labor-consuming and also expensive. However in many cases when concrete constructions require replacement, the considerable part of concrete constructions can be restored by cheaper methods. For this purpose it is necessary to remove a dilapidated surface layer of concrete (as a rule, in some centimeters in the thickness) to carry out a "sterilization" of a surface and to restore a concrete layer and/or to cover a concrete surface with a polymeric cover

The principle of installation action is based on processing of waste waters and wastes by a powerful beam of the electron accelerator. Both the Russian and foreign experience for last 10 years has proved high efficiency of this method and its universality for disinfecting of a wide spectrum of harmful impurities and pathogenic microflora. In many cases processing by an electron irradiation is the only way allowing to get positive result. For example, neutralization of water or industrial wastes with the high content of toxic organic impurities or ions of heavy metals cannot be carried out by any other of known methods because of high resistance of these products to influence of chemical reactants and heat

Energy-saving high-efficiency heat treatment of steels and alloys products by accelerated electrons in air became possible due to development of accelerating technique and growth of electron accelerator power. This kind of heat treatment is called radiation-thermal processing (RTP). The RTP is innovative electron beam technology for metal products properties improving. Depth of electron energy release reaches up to 10 mm, so heating depth of metal without heat conductivity participation can be comparable with a working layer of a product. It allows to carry out heat treatment in a pulse mode and to obtain working layers on a surface of products with qualitatively new nanostructure of a material. Steels and alloys with such a structure possess high hardness and simultaneously raised impact elasticity
