Dependence of Soil Hydraulic Conductivity of the Adopted Technological Solutions

Abstract

The aim of this study is to construct experimental and statistical dependencies filtration coefficient of the protected ground, formed by means of horizontal directional drilling, from technological factors. Methodology. Synthesis, analysis, mathematical methods. Findings. Analytical and image filtering coefficient depending on soil following technological factors: duration of injection, which is created using impervious screen bentonite powder concentration per unit volume of hardening mortar, and the discharge pressure (discharge) of the solution into soil. Originality. The regularities of the influence of technological factors (pressure, injection time and the characteristics of injection solutions) on the screen filtration coefficient. Practical value. The practical significance of the results is the development of new technologies to protect the underground space from pollution in soils with solids and lack of impermeable layer on the depth attainable.
