Together.
As a preferred embodiment, the high-strength layer uses warp knit by high-strength polyester industrial long filament and acupuncture nonwoven geotextiles
It weaves integrally formed.
As a preferred embodiment, the support drainage blanket material therefor adds the carbon of 2~3% parts by weight for high density polyethylene (HDPE)
The antioxidative stabilizer of black master batch, the ultraviolet absorber of 3~5% parts by weight and 3~5% parts by weight；The support drainage blanket
It is process by hot melt die head extrusion way, there is the 3 D stereo net of the tilting rib cross lapping of the tilting rib in upper strata and lower floor
There are reinforcing, resistance to deformation in shape structure, crosspoint.The 3 D stereo reticular structure of support drainage blanket is formed on its surface
Deeper drainage channels, drainage performance are equivalent to and are even more than the drainability of 1 meter of thick rubble.Support drainage blanket has
The superiority that conventional discharge pellet does not have, excellent croop property and long-term antibiotic corrosion and anti-silting performance, can
For relatively rugged environment..
As a preferred embodiment, the mesh fabric is woven using skin-core structure recombination line, the core of the recombination line
For polyester industrial filament yarn, the cortex of the recombination line is acrylic resin.A certain proportion of carbon black color is added in acrylic resin
The made plastics of masterbatch, age resister, antioxidant, ultra-violet absorber, stabilizer.The mesh fabric has infiltration coefficient
Greatly, drainage performance is good, and acid-alkali-corrosive-resisting, ageing resistance is excellent, many merits such as mechanical strength height.
As a preferred embodiment, the bound edge of the high-strength layer is using mechanical bound edge, bound edge width >=4cm.
As a preferred embodiment, the fixing buckle is anti-rust metal material.
As a further improvement, the geotechnological gauze pad is equipped with dry item quilting line arranged in parallel.
The beneficial effects of the invention are as follows:Three-decker is compact, can polylith splicing, reduce engineering construction difficulty, improve engineering
Quality and reduction engineering cost.
