SEISMIC RESISTANT PILE-SHELL OF HIGH BEARING CAPACITY Russian patent published in 2021 - IPC E02D5/38 

FIELD: construction.

SUBSTANCE: invention relates to pile foundations of buildings, structures, as well as foundations of bridge junctions, drilling rigs operating in the offshore zone of oceans and seas, as well as port hydroengineering protective and bank protection structures of pile type for ground conditions, including subjected to seismic loads. Pile-shell consists of metal sections and diaphragm installed in inner cavity of one of sections. To improve technological capabilities and reduce time for connection to upper part of section is welded funnel with arranged in it connecting elements, and in lower part of section there are windows, in which, when connected to flare of lower section, connection elements of flared ends enter, connecting elements at installation of upper section are bent towards central axis of pile-shell, allowing it to work on pulling loads.

EFFECT: technical result is to reduce the time of docking sections, increase labor productivity, increase bearing capacity of piles, reduce material consumption.
