PILE EARTHQUAKE-RESISTANT FOUNDATION OF BUILDINGS AND STRUCTURES Russian patent published in 2024 - IPC E02D27/34 

FIELD: construction.

SUBSTANCE: invention is intended for use in erection of pile foundations, which take up horizontal and seismic loads. Pile earthquake-resistant foundation of buildings and structures includes a grillage with a rigidly attached annular plate, piles and a cylindrical shell with an upper horizontal collar connected to the annular plate, placed in the ground coaxially to the grillage. Cylindrical shell has lower collar, note here that both collars are located on inner side of shell made of at least two identical recycled metal cord tires from heavy-duty truck. Annular plate in the center of its height has annular groove for tight arrangement of upper collar of cylindrical shell. Inside the shell there is a rib or ribs formed or formed by adjacent sidewalls of adjacent tires. Upper collar is formed by a circular cut of the upper sidewall of the upper utilized tire with a diameter equal to the diameter of the inner wall of the groove of the annular plate. Lower collar and rib or ribs are formed by circular cutouts of the lower side of the upper and both sides of the lower recycled tire or both sides of lower recycled tires with diameter equal to diameter of external contour of group of piles.

EFFECT: simpler and cheaper design of the foundation, as well as increased damping ability when damping seismic loads.
