METHODS OF INJECTION STRENGTHENING OF FOUNDATIONS IN CONSTRUCTION

Abstract

The article discusses the problems of strengthening strip foundations of buildings and structures. In accordance with the main reasons for strengthening foundations and artificially improving the construction properties of the soil foundation, the reserves and reserves of the bearing capacity of the soil foundation were assessed by analyzing the results of the technical condition of the building and analyzing its physical condition and mechanical characteristics. The exact dimensions of the foundation structures, their condition and the loads acting on them were determined, and the geological and hydrogeological conditions of the surrounding area were studied. A classification of methods for strengthening foundations and artificially improving the construction properties of the soil foundation is given; it is proven that strengthening methods depend on the design features of the building, types of foundations, operating loads, engineering-geological and hydrogeological conditions. In addition to the need to strengthen, as well as the capabilities and technical equipment of organizations performing this type of work, there are many other methods. Pile reinforcement methods are one of the most effective types of foundations. Research has proven that piles are not used to strengthen foundations, since the resulting dynamic impacts can lead to additional settlement of the building being restored. The study noted the basic requirements for reliable strengthening of the foundation and artificial improvement of the construction properties of the soil foundation, especially when water-saturated salty clay soils are formed at the base of the building.
