| description | The article deals with the creating of a universal material for protecting underground structures from groundwater as well as providing their thermal protection. The article presents a method for waterproofing and drainage of underground walling structures using drainage slabs made of filtration polystyrene foam and considers the possibility of using these slabs for reducing heat losses of heated underground structures. Thermal engineering characteristics of filtration polystyrene foam are determined, and calculations of heat losses of underground walling structures with slabs made of this material are given. The results of studies of the kinetics of water drainage by filtration polystyrene slabs are shown. The dependence of the heat conductivity of filtration polystyrene on humidity and other factors are also presented. Calculations of heat losses through the walls of heated underground premises are given, taking into account the temperature distribution in the ground along the depth of the structure. A comparative analysis of heat losses with the use of filtration polystyrene foam slabs and without them has been carried out. Based on the experimental results obtained, it was revealed that filtration polystyrene foam has not only high filtration characteristics, but is also an effective material for thermal protection of underground structures. |
