Abstract
The aim of the research was to experimentally evaluate the effect of pressure pulsations of a water stream on the stability of a free-lying anti-filtration coating made of BE-NOTEX SK concrete in a trapezoidal channel. The studies were carried out on a physical model in a laboratory tray with water flow rates of 84, 120 and 168 liters/s. The hydrodynamic pressure was measured synchronously on the surface of the coating and under it using DD-10 sensors, which made it possible to determine the pressure difference and assess the risks of tearing the web. A specialized measuring system with active filtering was used for signal processing. The dependence of the amplitude and frequency of pressure pulsations on the water flow rate has been established. It was revealed that the maximum peak frequency values (up to 800 Hz) are observed under the pavement on the slope. The pressure difference on the upper and lower surfaces of the web does not exceed 2.7 cm of water, which indicates the absence of significant tear-off forces. The coating remained stable without deformations at flow rates up to 1.86 m/s. Based on experimental data, the effectiveness of using BE-NOTEX SK concrete sheet as a protective coating of channels has been confirmed. It was found that to ensure stability, the minimum loading of the web can be reduced to 0.08-0.10 of the hydrostatic pressure value.
