What is the use of the black network when the shop is paved?
Roadbed can not hold, tamper with, it is similar to the old man with a mud house, mud with a wheat bran
Black net Is a grid geotextile bar. Geotextile isolation: the use of geotextiles with different physical properties (particle size, distribution, consistency and density, etc.) of building materials (such as soil and sand, sand and gravel, soil and concrete, etc.) to isolate. So that two or more materials are not lost, not mixed, to maintain the overall structure and function of the material, so that the structure of the load capacity to strengthen. 2, filament geotextile filter: When the water from the fine soil into the coarse soil layer, the use of acupuncture geotextile good permeability and water permeability, so that water through. And effectively cut off the soil particles, sand, small stone, etc., in order to maintain the stability of soil and water engineering. 3, filament geotextile drainage: geotextile is a good water guide material, it can form a drainage channel in the soil structure, the soil structure of the excess liquid and gas excluded. 4, filament geotextile reinforcement: the use of geotextiles to enhance the soil tensile strength and resistance to deformation, enhance the stability of the building structure to improve soil quality. 5, filament geotextile protection: the effective concentration of concentrated diffusion, transmission or decomposition, to prevent the soil by external force and damage. 6, filament geotextile closure: geotextile and other materials (asphalt, plastic film) with the formation of impermeable in the soil layer. (Mainly for road resurfacing, repair, etc.).
It is geogrid, can enhance the overall strength of the roadbed, from the role of tensile, mostly polyethylene materials.
