The study of interaction system between the asbestos cement pipe, laid in the ground with the surrounding soil is carried out. The interaction of the “pipe-soil” depends on the stiffness and flexibility of the pipes, which in turn characterize the tension under different conditions of laying. The surrounding ground is for asbestos cement piping a constant load, in which thermal deformation takes place. The magnitude and distribution of loads transmitted on asbestos-cement pipelines is influenced by characteristics of soil, laying depth method, reliance on the base and routing.
The results of the research showed that, depending on the diameters of the asbestos-cement pipes, the type and density of soils, dynamism of the carriageway, the asbestos-cement pipelines have a 35...50 % safety factor with an underground non-channel gasket and 100 % safety margin when laying them in channels at a depth from 0,8 m and more.
When assessing the quality of thermal networks, their heat losses play an important role, which mainly depends on the temperature of the coolant, heat-shielding properties and thickness of insulation, and temperature and humidity conditions of operation.
Of all types of insulation, the backfill is the simplest and less expensive, since it minimizes the technological processes thanks to its design, accelerates and reduces the cost of production |
