1.Soft pervious pipe for drainage features：
Soft Pervious for Drainage Pipe is rustproof coils of pipe support,
a high compressive soft structure, The nonwoven geotextile inside
lining filters, enables the siltimpurity in the admitting pipe,
thus achieved only seeps effect. Burned by the polypropylene fiber
coating has excellent water absorption, rapid collection of surplus
soil moisture.The wall of reinforced rubber coating and the spring
of a steel ring of organic integration, a good all-round flooding
function, and infiltration of water into a smooth, and the silt was
blocking impurities in the pipe, high penetration rate, large
drainage quantity, to replace the traditional PVC perforated pipe
water, easy to use so to flooding, filter, one go drainage
purposes.
2.Configuration:
1) The inner liner is a kind of steel wire with high strength and
the outer layer is covered by PVC material.
2) Filtration Layer: non woven geotextile
3) Water Penetration Material: the warp is nylon yarn with high
strength and the weft is a kind of special fibre.
4) Material for Joint: a kind of glue with high strength specially
used for PVC.
3.Application:
1） Drainage for airport, railway, highway, sports field, greenbelt
of garden, etc.
2） Drainage for tail dam of mines, ash dam of fire power plants,
rubbish burying field, etc.
3） Drainage for tunnels, retaining wall, roadbed, road surface,
etc.
4） Drainage for roof garden, low-lying and wetly farming field,
etc.
4.Acid and Basic Resistance experiment:
Soft Pervious Pipe for Drainage with high Acid and Basic
Resistance, The water and soil of organic or inorganic chemical
composition, the experimental results are as follows: (room
temperature 72 hours).
10% HCL solution without abnormal appearance.
10% NaOH solution without abnormal appearance.
