ASSESSMENT OF THE PROSPECTS OF USING CONCRETE CANVAS AS A FACING MATERIAL FOR COVERING IRRIGATION CANALS
Introduction. The expansion of theoretical and practical knowledge in the field of lining irrigation canals with modern lining materials along with traditional concrete lining is an important task for hydraulic engineering. Facing material - concrete canvas, appeared relatively recently in 2013. These facing materials are characterized by highly effective properties that can reduce the construction process, reduce costs, eliminate water filtration from the irrigation canal, improve environmental friendliness, and also intensify the technology of building irrigation canals. Object. The object of research is a concrete canvas. Materials and methods. The study was conducted at the Saratov State Agrarian University named after N.I. Vavilov. The experiment included empirical and experimental-theoretical methods. Results and Conclusions. A laboratory experiment has shown that the concrete sheet has a low moisture absorption rate in comparison with the control material - concrete lining. As a result of the experiment, conclusions were drawn about the admissibility of using a concrete canvas as an anti-filtration facing material on distribution irrigation canals.
