Hrynchuk O. Improving organizational and technological solutions for the construction of underground parts of civil buildings in technogenic urban areas

Formed solutions of scientific and practical importance to rationalize the parameters of organizational and technological solutions for the construction of underground parts of buildings, taking into account the influence of technogenic urban areas, including in conditions of compacted development. Analyzed and summarized design, technological and organizational solutions, regulatory documentation, taking into account the factors of influence on the parameters of construction and installation work during the construction of underground parts of buildings in technogenic territories. An experimental technique was developed and experimental studies of the interaction of piles in a polymer shell were carried out, taking into account the complex of features of the technogenic soil environment when reproducing the process of soil subsidence, and the effect of the shape of the pile trunk on a decrease in the magnitude of additional loading forces was investigated. Determined and systematized destabilizing factors that affect the features of the construction of underground structures on technogenic soils and affect the labor intensity, duration of work and durability of buildings. A method is developed for taking into account the influence of organizational and technological factors on the parameters of the process of erecting underground parts of buildings in technogenic urban areas, subject to the optimization of labor intensity and duration of work. Recommendations are formulated for technological and organizational solutions for the installation of conical piles in polymer shells and construction drainage, indicating the full cycle of the technological sequence of work, ensuring the extension of the life cycle of the object.
