Abstract

Nowadays, the decrease in number of urban areas for buildings is observed. Therefore, a novel construction of buildings has to be carried out in dense buildings areas. Construction buildings in historical districts become the most complicated goal. In order to preserve the cultural heritage, to ensure the safety of existing buildings and structures, and also safe building under, it is necessary to competently select the technology of digging pile foundations. Technological precipitation usually occurs at dynamic and vibration effects during the operation of equipment on the site and at pile construction. These effects cannot be analysed and depend on the quality of the work performed, the equipment chosen correctly and the technology applied. It is intended to eliminate the possible technological precipitation of buildings in the surrounding area by applying gentle technology-intensive operations. The article provides and systematizes defects that occur during CFA (Continuous Flight Auger), DDS (Drilling Displacement System), etc. The analysis of factors that influence on the appearance of defects has been made, and also the estimation of technologies from the preparation of wells when installing drilling and embroidery piles on the surrounding development in weak soils has been made.
