Approbation of results of researches for the development of injection technology of creation of anti-filtering screen

Formulation of the problem. This article contains information on the conduct of experimental studies on the approbation and study of injection technology for creating an anti-filtration screen. In Ukraine, at the sites of disposal of radiation and other wastes, the issue of protecting underground space in places with a deep layer of the waterproof layer is urgent. Classical methods can`t fully solve such problems. In the previous studies on laboratory stands, the main quality indicators and characteristics of the screens were determined. Also, various technological compositions were worked out. In this paper, it is necessary to test the technology in conditions as close to real as possible. To study such indicators as radius of distribution of the dissolver in the ground environment, the time of hardening of the composition, and also the coefficient of filtration, which characterizes the anti-filtration properties of the screen. Goal. The purpose of this study is the development of the developed technology and its validation in conditions of full-scale experiment, which is as close as possible to real ground conditions. It is also of interest to study the technological parameters of injection and the quality of the screen. Conclusion. As a result of testing and full-scale experiments, the technology was developed and the technological parameters of the injection process were obtained. The real radius of solution propagation in the given ground conditions is determined, so the qualitative characteristics of the screen are investigated, which in future will allow to carry out the work on the introduction of technology in the production.
