Недостатком известных фундаментов является недостаточная несущая способность и неудовлетворительное взаимодействие их с грунтовым основанием.Known foundation consisting of opor- Neu shell placed in a ground based Bani ^s INaibolee closest technical solution to the invention is a foundation, comprising the compacted filled syyuchim pictures sheath ¹⁰ with the open third and simply supported on a particulate support material with a glass shoe in the central portion, this shell is made cylindrical and vertically installed in the soil of the base £ aQ. ^{, 5} . A disadvantage of the known foundations is the insufficient bearing capacity and their unsatisfactory interaction with the soil base.

Целью изобретения является повышение несущей > способности фундамента и улучшение условий его взаимодействия с грунтовым основанием.The aim of the invention is to increase the bearing> capacity of the foundation and improve the conditions for its interaction with the soil base.

Поставленная цель достигается тем, что фундамент под колонну, включающий заполненную уплотненным сыпучим материалом вертикально установленную опорную оболочку и размещенный на сыпучем материале опорный башмак, выполненный со стаканом в центральной части, снабжен горизонтальной, плитой, выполненной с центральным вырезом, при этом оболочка установлена на грунт основания и выполнена в вертикальном Jсечении в виде трапеции, обращенной меньшим основанием вверх, башмак выполнен в виде расширяющейся к кверху оболочки, обращенной своей выпуклостью к сыпучему материалу, причем концевые участки оболочки башмака размещены на верхних кромках опорной оболочки, а очертание выреза горизонтальной плиты соответствует очертанию стакана в плане, горизонтальная плита примыкает по наружному контуру и контуру выреза соответственно к кромкам оболочки башмака и стенкам стакана, а угол наклона стенок опорной оболочки соответствует углу внутрён3 737572.This goal is achieved by the fact that the foundation for the column, including a vertically mounted supporting shell filled with compacted bulk material and a supporting shoe placed on the bulk material, made with a glass in the central part, is provided with a horizontal plate made with a central cutout, while the shell is installed on the ground the base and is made in a vertical J-section in the form of a trapezoid, with the smaller base facing up, the shoe is made in the form of a shell expanding towards the top, facing its release bulk material, and the end sections of the shoe shell are located on the upper edges of the support shell, and the outline of the cutout of the horizontal plate corresponds to the outline of the cup in plan, the horizontal plate is adjacent along the outer contour and the contour of the cutout to the edges of the shell of the shoe and the walls of the cup, and the angle of inclination of the walls the supporting shell corresponds to the angle of inner

The invention relates to the field of construction, in particular to the implementation of the foundations for columns of industrial and high-rise agricultural buildings. The foundation is known, which consists of supports of a shell placed in the ground of an irrigation (Y .. The closest technical solution to the Invention is a foundation that includes a shell filled with compacted blunt material with open namesake and a grated supporting shoe with a glass in the center parts, while the shell is made by cushioning} vertically installed in the soil of the base 2. A disadvantage of the known foundations is the lack of carrying capacity and poor interaction of the BOt with The base of the isobregnation is to increase the bearing capacity of the foundation and improve the conditions for its interaction with the ground foundation. The goal is achieved by the foundation of the column, including a vertically mounted supporting shell filled with compacted bulk material and placed on the bulk material supporting shoe made with a glass in the central part, provided with a horizontal slab, made from the center of the cutout, this membrane is installed on the ground of the base and made A vertical cross section in the form of a trapezium with the smaller base facing upwards, the shoe made in the form of an enlarging to the top of the shell, with its convexity to the earthing material, and the ends of the shoe shell are placed on the upper edges of the support shell, the outline of the cup in the plan, the horizontal plate adjoins along the narrow contour and the contour of the cutout, respectively, to the edges of the shoe shell and the walls of the cup, and the angle of inclination of the walls of the support shell, respectively tvuet corner vnutren373 Herd compacted friction si la uchego mother.
