Kunanets Y. Reinforcement of foundations with the help of micro piles made by shockless pressing

The dissertation is devoted to experimental and theoretical researches of bearing capacity of the pressed pipe concrete micro piles and their subsidence. The prototypes differed in length, diameter and different engineering and geological conditions. The design of the pile tip was developed and a method was used to study the nature (features) of the micropile and obtain a qualitative (real) distribution of the ultimate resistance of the soil under the heel and on its side surface. The technique of adding piles by a thermal method for their inclusion in work with a monolithic grid plate is developed and tested. The results of the dissertation research were applied during the design and execution of reinforcement of the foundations of buildings on real objects. Based on the results of experimental and theoretical studies, appropriate recommendations were developed for the design of reinforcement of foundations using micropiles.
