METHOD TO LAY VOLUME GEOGRID INTO ROAD STRUCTURE, VOLUME GEOGRID AND LAYER FOR LAYING OF VOLUME GEOGRID Russian patent published in 2014 - IPC E01B29/05 

FIELD: construction.

SUBSTANCE: group of inventions relates to the field of road construction. The method is proposed to lay a volume geogrid into a road structure, as well as a volume geogrid and a layer of a volume geogrid. The method to lay a volume geogrid consists in the fact that the geogrid is withdrawn from a device that contains it, in a mechanised manner it is stretched on the road section prepared for improvement, and sections of the geogrid are transformed into a cellular volume structure, afterwards filled by material as specified in the project. The volume geogrid is made of polymer tapes of certain length, width and height welded to each other in a staggered manner with a pitch that determines the size of the cell. The layer comprises a device to stretch a geogrid with working elements designed for insertion into pockets at the left and right side of the geogrid section.

EFFECT: invention provides for improved efficiency of volume geogrid laying.
