AbstractAbout AuthorsReferences
The article deals with the case of geotechnical practice of strengthening the overloaded base of reinforced concrete foundation slab of a 25-storey residential building at the construction stage. Combined ground piles, consisting of ground-concrete piles Get (type 1) reinforced along the longitudinal axis with bored-injection piles produced according to the electric discharge technology (piles EDT) are used as buried structures. This method of arrangement of the combined buried reinforced concrete structure is due to the need to increase the bearing capacity of the Get pile according to the ground twice or more. The plans and sections of ground concrete piles, which are designed 14–19 meter length with a bearing capacity according to the ground from 1100 kN to 1500 kN are presented. At this the factor of reserve of the bearing capacity of the strengthened base is K=1.4.
