Abstract

The problems of strengthening mountain slopes, slopes of artificial structures and banks of water bodies are considered. The methods, materials and structures used for this purpose are given with a brief description of the work performance techniques. The experience of protecting mountain slopes due to the force inertial compaction of the concrete mix prepared in a special hermetic high-speed compulsory concrete mixer is indicated. The mixture under pressure is uniformly transported along the material line at a speed of 120-200 m/s to the nozzle. The schemes of the force inertial compaction of the concrete mix and the composition of a mechanized complex for its preparation, transportation and application are considered; recommendations are given on the composition of the team and its functions. The method of dry concreting under high pressure ensures environmental friendliness, which eliminates the need for using respirators and other protective equipment and expensive treatment plants.
