| Title of the article | Improving the technology of insulated shallow strip foundations |
| Abstract. | Problem statement. Use of shallow foundations in low-rise construction is one of the most economical solutions compared to other types of foundations, as it requires minimal material and labor costs for its construction. In this regard, it is important to study the specifics of the technology of their construction and insulation, taking into account the climatic conditions prevailing in our country. The purpose of this study is to optimize the thermal insulation consumption in the foundation structure by modeling and then calculating the thermal fields of the basement and the foundation structure in winter. Results. Based on the results of the study, the effective parameters of the thermal insulation contour of a shallow foundation were determined. To avoid freezing of the soil under the base, it is necessary to ensure the following minimum dimensions: the depth of the horizontal layer of thermal insulation is at least 340 mm, the width of the thermal insulation skirt is from 1050 mm. It was found that the proposed solutions for thermal insulation of shallow foundations provide significant optimization of material consumption: the thickness of the horizontal insulation layer is 34% less, the vertical layer is 14% less, and the skirt width is reduced by 8.3% compared to the recommendations of standard STO 36554501-012-2008. At the same time, the total saving in thermal insulation materials reaches 31% of the recommended volume, which does not affect the operational reliability of the structure. Conclusions. The results obtained are of great practical importance for the construction industry, as they allow optimizing the material and labor costs for the construction of shallow foundations while ensuring their operational reliability in conditions of deep soils. The developed recommendations can be used in the design of low-rise buildings in regions with a cold climate. |
