Abstract

The invention relates to the construction of foundations, mainly in heaving soils. The purpose of the invention is to facilitate manufacture and reduce material consumption. The bored foundation, erected in heaving soils, includes a barrel with a antimucosal shell located in the well. The barrel is made in the form of a hollow box vertically open along the ends of the box 4 with an outer coating 5 of antifreeze material filled with a concrete mixture and an annular diaphragm 6 rigidly attached to it from the bottom, which has supporting elements. The height of the box 4 is not less than 0.7D _F , where D _F is the depth of seasonal freezing of the soil. The maximum cross-sectional size of the duct 4 is smaller than the diameter of the well 1. The cavities between the walls of the duct 4 and the well are filled with local soil 10, which, together with the duct coating, forms a rubber sheath. 8 il.
