Product Description
DESCRIBTION:
Polypropylene filament needle- punched geotextile is an important geosynthetics. It has been listed as a key technical project by the Ministry of Science and Technology of China, but it has not been industrialized In 2016. the Ministry of Science and Technology re-listed it as a key basic material and industrialization special project. Dongfang Rainbow is the main research and development unit of the project.
High Strength Coarse Denier Spinning Laying Technology
Oriental yuhong adopts advanced spinning technology. The fineness of geotextile fibers can reach 11D,which is 3-4 times that of traditional technology. The strength of single filament exceeds 3.5G/D. It is calledhigh strength coarse denier fibers.
This kind of fiber has higher strength and modulus, so it has excellent mechanical properties, excellent permeability,water conductivity, moderate voids, not easy to plug. It is an excellent geosynthetic material, widely used in airportrunway, highway engineering, railway engineering, water conservancy engineering Ecological ramps and other projet.
Main application areas:
1: Airport runway isolation layer:100-160g/m Polypropylene
Filament needle-punched geotextiles(hot-rolled)
The airport runway layer is laid between base and the surface of the road. It is mainly
used to improve the interaction between layer,prevent reflection cracksand damage of various layers,improve the load distribution and prolong the service life of the runway.
2: Waterproof and crack-proof base for highway:150g/m Polypropylene filament
needle-punched geotextiles(hot-ironed or single-sided singeing)
It is used for highway overhaul and new construction to prevent highway cracks
It forms waterproof and crack-proof layer with hot asphalt, and effectively reduces reflection cracks of semi-rigd base course
3: Ballastless Track Isolation Layer for High-speed Rail:600g/mor 700g/hg Polypropylene
filament needle-punched Geotextiles
It is laid between concrete and base slabto reduce the influence of temperaturechange, concrete shrinkage and Bridgedistor tion on track structure. It also hasa certain cushioning effect and provdes convenience for track maintenance.
4: Tunnel anti-seepage cushion:300-400g/m Polypropylene filament
needle-punched Geotextiles(Flame retardant)
It is lad between tunnel concrete and waterproof board, used to protect waterproof board and filter impurities.to avoid blockage of drainage system.It has natural advantages in long term contact with alkaline cement.
5: Revetment of irrigation works:300-600g/m Polypropylene
filament needle-punched Geotextiles
It is laid on the surface of rivers, earth-rockfill dams, with gravel and stone cage nets to protect the ecological balance and reduce soil erosion. This method is economical,. efficient and can reduce the workload.
6: Ecological slope protection project:120-150g/m Green or Black polypropylene filament geobag(Anti-aging)
It has good water permeability and filtration. plant growth and nutrient organic matter is not easy to lose .it can be used for any geological slop, bare rock zone can also be quickly greened.
