Petrovsky A. Injection technology of underground space protection

Object - technological processes of the device of anti-filtration screens for soil protection from pollution sources; The goal is to protect the underground space from contamination if there are solid inclusions in the ground and there is no water retainer at the reachable depth; Methods - generalization and analysis, theory of reduced planning and optimization of experiments, full-scale, laboratory and computational experiments, experimental statistical modeling; Results - innovative inkjet and injection technologies for protecting the underground space from pollution have been developed, almost completely waterproof horizontal anti-filtration screen; The novelty lies in the development of the scientific foundations of injection technology for protecting the underground space from pollution when there are solid inclusions in the ground in the absence of a natural waterproof; Implementation - in the organizational and technological design, in construction at sites in Ukraine (screen under a storage pond in Kiev) and in the Czech Republic (screen under a sewage pool in Brno).
