Design of Impervious Coatings with Enhanced Reliability Made from Innovative Materials

By Y.M. Kosichenko and O.A. Baev

Abstract

AbstractThis article considers development and research issues of creating impervious screens with enhanced reliability for irrigation canals, ponds and reservoirs using geo-composite materials (geomembranes, bentonite mats and other). In this connection, the authors conducted the present research and impervious screens that provide a high impervious effect and a long service life were developed. Also, the process of water permeability of probable damage inlets in the geocomposite screen was conducted in the form of small holes using Comsol Multiphysics software package. A hydro-mechanical method based on the conformal mappings method was used to find an analytical solution for the problems. Dependences were obtained to estimate the permeability of the geocomposite screens design for plausible accidental damages: seepage losses per unit damage and the average filter coefficients, given the size of the damage and the frequency of distribution. Based on the calculations, using the derived formulas, a graph was drafted, summarizing the degree of permeability of the geocomposite screens, based on which the rational field of their application was determined and the requirements for impermeability indices were set
