Title of the articleImproving the device technology of shallow energy-efficient foundations
Abstract.Problem statement. The analysis of foreign experience in the construction of foundations of low-rise buildings shows that one of the most economical, energy-efficient and requiring little labour costs for the device is a shallow heat-insulated foundation. In this regard, it is important to study the features of the technology of their installation and insulation, taking into account the climatic conditions of our country. The purpose of the study is to determine the optimal thickness of the insulation of a shallow foundation. Results. Modelling and calculation in the «Elcut» software package revealed that the lack of freezing of soil under the basement of the foundation is possible with horizontal insulation of the blind area 1000 mm long and 50 mm thick insulation, with vertical insulation 100 mm thick. With this option of insulation, a reduction in the consumption of horizontal thermal insulation by 2 times, and vertical – by 1,5 times is achieved in comparison with the requirements of current standards. At the same time, significant savings are made on the labour costs of the insulation device. Conclusions. The significance of the results of the work for the construction industry is to increase the efficiency of insulation of shallow foundations while ensuring their operational reliability and rational use of the required materials.
Keywords.shallow foundation, insulated Swedish plate, extruded polystyrene foam, heat engineering, Elcut.
