Improvement of the technique and technology of filling closed cavities in the foundation with cement-concrete mixtures
The paper provides a brief overview of the technologies of concreting thin-layer concrete cavities in foundations for installing equipment with high unit capacity and significant weight and size dimensions, which leads to an increase of contact bearing surface areas and causes greater non-stationary vibration loads on the bearing surfaces. Some original technologies of concreting thin-layer cavities foundations are analyzed, their advantages and disadvantages are identified. Directions for further research in the area are identified, which allows increasing the efficiency of the technological process, namely, the use of vibration, improvement of concrete mixtures` content, classification of the design features of thin-walled cavities.
