Specialists from Samara State Technical University (Samara State Technical University) have presented an innovative technology that allows to significantly strengthen pile foundations with the help of polymer resins. According to test results, the use of this technology can increase the bearing capacity of the foundation by as much as 50%.
The development, carried out by the Faculty of Industrial and Civil Engineering, is aimed at solving a problem that often arises during construction — the accumulation of drilling sludge at the bottom of wells. This can reduce the strength of bored piles. The scientists proposed creating a special widening made of polymer material under the base of the pile, pumping expanding resins there.
According to Andrey Maltsev, Associate Professor of the Department of Structural Mechanics, Engineering Geology, Foundations and Footings, the uniqueness of this technology lies in the use of polyurethane-based resins. They are able to increase in volume due to the reaction of two components, which allows them to quickly fill voids in the ground.
Field tests have confirmed that the new technology really increases the strength of the pile foundation by 50% or more. This not only improves the reliability of structures, but also reduces material and labor costs, as it allows to reduce the length of bored piles without compromising their strength.
The development of scientists from Samara State Technical University opens up new opportunities in construction and can significantly improve the quality of foundations in various projects.
