UNDERGROUND PART OF CONCRETE WALL WITH WALL DRAIN Russian patent published in 2012 - IPC E02D31/02 

FIELD: construction.

SUBSTANCE: underground part of a concrete wall with a wall drain comprises a filtering shell made of a polymer material and vertically laid onto the external surface of the wall to form channels draining water from soil fill into the fill of a drain pipe connected to a drain header. The external surface of the wall is coated with a geomembrane, which is arranged from a polymer material and with its anchor ribs fixed to the wall and forms its protective hydraulic insulation. The filtering shell is arranged in the form of a geogrid and a filtering nonwoven material attached to it at the side of the soil fill, at the same time geogrid cells are formed by crossing rods laid one onto the other and fixed in points of crossing with each other.

EFFECT: higher reliability and durability of a building or a structure, higher quality of wall protective hydraulic insulation and improved water-draining capacity of a filtering shell.
