RESULTS OF STUDYING HYDRAULIC PROPERTIES OF ANTI-EROSION CONCRETE SHEET OF BENOTEX SK BRAND

The aim of the study was to determine the roughness coefficient of the BeNotex SK concrete sheet. The features of the model installation for determining the hydraulic characteristics of the concrete sheet are considered and the method for determining them is described. The hydraulic studies were aimed at determining the roughness coefficient of the studied coating. The studies were carried out on an experimental installation of trapezoidal cross-section with a vertical right and inclined left slopes. The study of the roughness coefficient “n” was carried out on a control section, the walls and bottom of which were completely covered with the sheet. The length of the working section with the material under study was 6 m. The average value of the roughness coefficient was found and recommendations were given for using such a coating as an anti-erosion coating. The hydraulic studies carried out for the Be-Notex SK concrete sheet material showed positive possibilities for using such fastening in the practice of irrigation and drainage construction.
