MACHINE FOR LAYING OF GEOSYNTHETIC MATERIALS INTO ROADBED AND METHOD OF ITS OPERATION Russian patent published in 2016 - IPC E01C21/00 

FIELD: construction.

SUBSTANCE: method of laying of geomaterials is aimed at the expansion of a possibility of application of ground-strengthening geomaterials, such as a volume geogrid and geotextiles as far as it allows in a mechanical manner, using a high mobility carrier, to equip with them an unlimited surface area in any task-dependent direction, with an easy method of storage and use of the geogrid (package), at less complex design as far as there is no (known by a prototype) drum, with the string of a volume geogrid wound on it, and the devices providing and regulating the speed of rotation of the drum, while in the package the larger length of the string of the geogrid is stored, than in the drum with dimensions, allowable for road transport, that reduces idle time connected with the replenishment of consumable material. The technical solution allows performing works on equipping the roadbed at the essential reduction of manual operations and time of work execution.

EFFECT: design of the offered machine for the implementation of the method consists of a standard high mobility carrier, a platform with packages of a volume geogrid, a device for the maintenance of geotextiles rolls, devices installed on it for pulling of the volume geogrid from the package, its extension to the required size, devices for the conservation of the extended geogrid form before its fixing by a backfilling mix, devices for the storage of the backfilling mix, its transportation on the stretched geogrid, levelling and compaction.
