We consider an articulated reinforced beam from a bimodule material on an elastic base under the action of a concentrated force. Numerical investigation of the influence of the bimodule property of the beam material on the bending moment and deflection is given. The influence of the elastic bedding coefficient on the value of the maximum normal stress, the maximum bending moment and the maximum deflection is shown. Investigations were carried out for fibre-foam concrete beams, for which tensile modulus and compression moduli obtained experimentally are known. Numerical studies have shown that taking into account the bimodulity of the material, that is, taking into account the difference in elasticity modulus between tensile and modulus of elasticity for compression for concrete, leads to the need for calculation of strength both in tensile and compressive stresses.

From the pilot section of the gas pipeline, after ten years of operation, specimen-witnesses were seized. The gas pipeline consists of reinforced polyethylene pipes with an average adhesive reinforcing layer. The results of mechanical tests of model samples are given in the article. Investigations of the deformation-strength properties of the witness specimens show a decrease in the temperature of the viscous-brittle transition to -15 ° C. These results indicate a deterioration in the adhesion between the outer layers of PE80 and the middle technological layer. Good adhesion led to the emergence and development of a fragile crack. Stability tests at constant pressure showed satisfactory results, not a single sample collapsed. According to the research data, the reinforced polyethylene pipe did not deteriorate its deformation-strength properties for ten years of operation of the gas pipeline under pressure.

It is noted that traditional technologies do not provide removal of organic substances from water, and primary chlorination leads to the formation of highly toxic halogen organic compounds in it. The perspective of using membrane technologies for water purification of surface sources based on: micro-, ultra- and nanofiltration, reverse osmosis, allowing to solve the set task is shown. This was realized during the purification of the Don and Moscow rivers with the use of the biosorption-membrane method, which involves sorption on activated charcoal, biological oxidation of organic substances and filtration through the membrane. The obtained results give the basis for wide application of this method in treatment plants of small settlements, which is especially important for the south of the country, in particular, the Rostov region and the Republic of Kalmykia.
