FIELD: construction.SUBSTANCE: geomaterials - geotextile and volume grating are stretched onto an area of an earth bed prepared for development with a traction force of a special road machine. Geomaterials are taken from those available on the machine or on upkeep device platforms coupled with it. Besides, the volume grating is installed above geotextile and transformed into a cellular volume structure, which at the start section is fixed to soil with several time anchor stands. Then it is immediately filled, levelled and compacted to avoid displacement with a material specified by the project (sand, sand and gravel mixture, crushed stone, etc.) from the one available on the machine or a hopper coupled with it.EFFECT: improved manufacturability, reduced time for performance of works, reduced manual labour of roadworkers.2 cl, 2 dwg |
