GROUND ANCHOR OR DRILLING PILE AND MANUFACTURING METHOD OF GROUND ANCHOR OR DRILLING PILE Russian patent published in 2015 - IPC E02D5/80 

FIELD: construction.

SUBSTANCE: manufacturing method of the ground anchor or drilling pile includes formation of the hole in dispersed soil, filling it with hardening plastic material, soil compaction, surrounding the shaft of the pile to be manufactured or anchor root, discretely with formation of dynamic and / or static influence of broadening, which is formed by compaction and partial displacement of soil in each broadening, so that the stress-strain state of the soil adjacent to the broadening has reached the value of the stress-strain state of the soil at the base of the pile, in this case the maximum distance l between the centres of broadenings along the hole axis is determined by the reduced dependence.

EFFECT: provision of specific load-bearing capacity of the soil along the anchor root, reduction of consumption of cured material, increase of productivity in the manufacture of bored piles and ground anchors at the same time with increase of their load-carrying capacity due to the effective use of the bearing capacity of the soil.
