FIELD: construction.
SUBSTANCE: device for increasing lateral stability of assembled rails and sleepers section contains ballast prism and retaining structure in the form of anchor. Retaining structure comprises a geogrid, consisting of vertical and horizontal planes, interconnected at the angle of 90 degrees. Vertical plane is parallel to track axis with its outer side. Horizontal plane is located on the main platform of road bed. On vertical surface of geodrid there are fibre-glass rods evenly arranged along the length fixed by means of loops made by ultrasonic spot welding.
EFFECT: simplified retaining structure and elimination of corrosive elements.
