Improving the safety of buildings operation in terms of building density

Abstract

When erecting buildings and underground structures in cities, it is often not possible to carry out work safely in the conditions of building compaction. It is impossible not to affect the houses in the immediate vicinity of the new construction. As a result of excavation work on the ditches of the load-bearing structures of underground structures, existing houses may experience uneven rainfall. Cracks appear in the walls or there are violations of the serviceability of individual structural elements. This is a factor of man-made danger to humans.
The article presents an overview and analysis of ways to strengthen the foundations and foundations of existing buildings exposed to loads from construction work during excavation.
It was revealed that the solution of the problem of emergencies and safety of operation of existing buildings in the conditions of compaction of construction in many cases can be prevented if professionally and in full to monitor the construction site of sunken structures. The occurrence of additional subsidence of existing buildings and structures in the conditions of conducting new construction next to them can be due to a large number of reasons. The article highlights the types of additional drawdowns of existing buildings.
To ensure the safe operation of buildings, an analysis of soil consolidation methods is proposed. Taking into account the engineering and geological conditions of the construction site, possible ways of fixing the soil by various technologies have been identified. Methods of soil strengthening are analyzed, their advantages and disadvantages are revealed. Application of borehole injection piles is a universal way of production of works
