METHOD OF PILED CONSTRUCTION IN TRANSIENT SOILS UNDER CONDITIONS OF DENSE URBAN BUILDING Russian patent published in 2019 - IPC E02D5/48 

FIELD: construction.

SUBSTANCE: invention relates to the field of construction, in particular, to methods of construction of piles for construction of buildings and structures, mainly on subsidence soil in conditions of dense urban development. Method of erecting piles in subsidence soil in conditions of dense urban development, including installation of pile 1 with widened head 3 in formed in ground well 2 with a gap, and filling gap. In the proposed solution, well 2 is formed by drilling the drilling rig to design mark 8, and pile 1 made with widened foot 3 is buried in non-subsidence soil 9 using a vibration method or an indentation, wherein during pile 1 deepening, clearance between pile side surface and borehole walls is filled with prepared blend 5 with non-explosive destructive substance with water.

EFFECT: invention is aimed at increasing bearing capacity of a pile erected in subsidence soils in conditions of dense urban development, due to exclusion of forces of negative friction during soil sagging.
