Annotation:
The article is devoted to the problem of safety and reliability of water management systems. Most of these systems in the North Caucasus are in unsatisfactory condition, which leads to a rise in the groundwater level, salinization and contamination of adjacent lands, flooding of territories, pollution of places of residence and a decrease in the standard of living of the population. For the repair and restoration of systems and prevention of environmental damage to environmental components, by reducing filtration losses, both under normal operating conditions and under seismic impacts, precast concrete elements on inexpensive non-composite aggregates are proposed. Despite their (aggregates) relatively low quality and availability, concretes and trays, pipes and slabs made of it are characterized by a high resource-saving effect and meet the requirements of safety and reliability. This is achieved by adding a formiate-alcohol plasticizer to the concrete mixture, which has a super-liquefying effect that reduces the water consumption of the concrete mixture (water-reducing effect) and increasing the construction, technical and operational properties, including the reduction of seismic activity. The recommended proposals will significantly reduce the losses of water supplied to consumers, both in normal and extreme operating conditions, prevent flooding, pollution and waterlogging of adjacent territories, and improve the living conditions of the population.
