METHOD FOR CREATION OF A WALL IN THE GROUND Russian patent published in 2023 - IPC E02D5/20 

FIELD: construction.

SUBSTANCE: invention relates to the field of construction and can be used in the construction of impervious or enclosing structures in the ground for the construction of structures for various purposes in weak water-saturated soils. The method for creating a wall in soil includes excavating a trench under the protection of a thixotropic mortar, installing a building element, using different-pole electrodes with passing electric current through them, supplied from a current source with negative and positive leads, and filling the trench with concrete. The inner surface of the trench, moistened with a thixotropic solution, is subjected to electrophoresis for 10-15 minutes at a current strength of 300-320 A and a voltage of 30-60 V, while to create it, a metal reinforcing cage is installed as a building element, which performs the function of an electrode with a negative pole, and electrodes with a positive pole are installed in the ground on both sides of the trench, symmetrically and at a distance of 0.6-1.5 m from its edge. To maintain the mobility of the thixotropic solution, the metal reinforcement cage is subjected to low-frequency mechanical vibrations using a vibrator, which is placed on top of the metal reinforcement cage. After electrophoresis, the electrodes are disconnected from the power source, the vibrator is removed and the trench is filled with concrete based on fine-grained filler.

EFFECT: ensuring the development of a method for constructing a wall in the ground with improved performance characteristics, ensured by the stable state of the trench walls when they are received and their low water permeability, which significantly reduces contact with possibly aggressive underground water, which is achieved by clogging soils in the trench space, between opposite-pole electrodes and a crust from the dispersed phase thixotropic mortar, along the wetted perimeter of the trench.
