Development of auger technology for creating protective screen

Formulation of the problem. This work is devoted to the development of auger technology for creating a protective screen. Every year the volume of construction activities performed to protect the environment from the filtration of harmful industrial wastes and substances from various decanters, storage devices and storage facilities is increasing in Ukraine. In a large variety of existing technologies of security screens installation, the main place is allocated to screens, which are arranged in an open way. However, a number of the above-mentioned structures is not possible to move or drain. In order to perform such works, in such circumstances construction in an open way is impossible. Alternative technologies are becoming closed construction technologies of building screens. Although such technologies have also disadvantages, there are ground conditions in which the use of closed methods may be limited, such as the presence of solid inclusions, the size of which will not allow the passage of a given path of the working body, or nonhomogeneity of the soil structure, which in turn will not ensure equal distribution of an isolating or strengthening compound. These factors determine the necessity of developing an innovative technology for the arrangement a horizontal impervious screen in a closed way based on a horizontal directional drilling. Goal. The purpose of this study is to develop a technology for protecting the underground space from contamination, and the installation of a waterproofing layer of the screen if there are solid inclusions in the ground, soil nonhomogeneity and absence of water resistance at an achievable depth. Conclusion. The developed technology will allow to make impervious screen under existing sources of pollution, in soils with solid inclusions and in non-uniform ground that do not allow to apply existing technologies of carrying out such works.
