PIT OF BUILDINGS AND STRUCTURES IN WATER-SATURATED SOILS Russian patent published in 2024 - IPC E02D17/04 

FIELD: construction.

SUBSTANCE: construction of the underground part of building structures in conditions of flooded soils. The pit of buildings and structures in water-saturated soils for the underground part of building structures contains side fences in the form of continuous waterproof walls, an anti-filtration curtain created by treating the soil structure with a mineral-based injection mixture containing a base mixture of Portland cement, or microcement, or a cement, a weighting agent, a viscosity regulator and a sedimentation stability regulator. As a weighting agent, the base mixture of the anti-filtration curtain contains: barite, or magnetite, or hematite, or galenite, or ilmenite, or a mixture thereof. The side fences in the form of solid waterproof walls are fixed at the lower end as a rigid embedment into the anti-filtration curtain, at distances from the center of symmetry of the anti-filtration curtain, ensuring the presence of protrusions of the edges of the anti-filtration curtain outside the attachment points of the solid side waterproof walls.

EFFECT: reducing the depth of the wall in the ground and the depth of the pit, reducing material consumption and increasing reliability.
