Using biopositive constructions made of composite materials in water and electricity supply for recreational facilities

The article is devoted to the questions of scientific substantiation and experimental research of parameters of biopositive structures from composite materials for water and energy supply for the decentralized small recreational objects. Biopositive structures include water intake structures and waterways made of composite materials with engineering protection structures and fastening along its route. The experimental studies of the physical model of the diversion water conduit were carried out on a variable-slope hydraulic tray. The method of telemetry was used to determine the stress-strain state of the water conduit shell from a composite material at various water flow rates. Based on the results of measuring the stress-strain state, the maximum stresses in the shell of the diversion water conduit are determined, which make it possible to clarify the necessary strength characteristics of the composite material and the conditions for its fixation. To ensure the laying of the water conduit through areas of complex relief, a device of soil-reinforced structures is envisaged. These structures ensure the fastening of the water channel. Since it is necessary to ensure the reliability of the functioning of soil-reinforced structures, statistical processing of the previously conducted experimental studies of deformations of these structures is performed. Based on the results of experimental studies, an empirical dependence was obtained to determine the reliability of the functioning of the soil-reinforced structure for securing the shell water conduit from composite materials.
