ELEMENT OF LINING FOR USE IN STRUCTURE WITH STABILISED SOIL Russian patent published in 2014 - IPC E02D29/02 

FIELD: construction.

SUBSTANCE: invention relates to a lining element for use in a structure with stabilised soil. A lining element for use in a structure with stabilised soil comprises a facade surface and a rear surface stretching in longitudinal direction along the axis X and in vertical direction along the axis Z, the body between the facade and the rear surfaces, besides, the body comprises at least a hollow part with a hole on the rear surface, in which there is a cylindrical core at least partially located and strongly connected to the body for formation of a zone of fixation for a fill reinforcement strip. At the same time the cylindrical core stretches substantially in parallel to the longitudinal axis X, and its cross section in the plane (Y, Z), perpendicular to the plane (X, Z), comprises two continuous parts separated by an imaginary straight line in direction of the axis Z, at the same time the first part has a continuously reducing size along the axis Y from the imaginary straight line to the end part, substantially in direction opposite to the rear surface of the lining element. The second part has a permanent and/or continuously reducing size from the imaginary straight line to the end part in direction to the rear surface, at the same time: L₂ ≥ 1.1 × d₁; A ≥ 0.24 × d₁ ²; where: L₂ is the distance between the end part of the first part and the rear surface measured in direction of the axis Y; d₁ is the width of the cylindrical core measured in direction of the axis X in the end part of the first part; A is the area of the cross section of the cylindrical core in the plane.

EFFECT: increased bending strength of a lining element core.
