(Also known as: plastic blind ditch, drain pipe), hard permeable pipe upper part 2/3 with small holes, lower part 1/3 without holes, can prevent secondary leakage of groundwater, rapid drainage of groundwater.
1. Product introduction
(Also known as: plastic blind ditch, drain pipe), hard permeable pipe upper part 2/3 with small holes, lower part 1/3 without holes, can prevent secondary leakage of groundwater, rapid drainage of groundwater.
Products are used in railway construction, highway construction, Airport runway, golf course, football field, large lawn, garden greening, highway, landfill, slope retaining wall, tunnel and other large dredging underground water permeability projects.
2. Product characteristics
Light weight, easy to transport and operate. The temperature range of adaptation is wide. Weather resistance (anti-aging) is superior, and its service life is very long. Strong impact resistance, excellent chemical corrosion resistance. The catchment capacity is very strong, which is 5 to 10 times that of other similar products. [1] The fluid flow rate is 2 to 3 times faster than that of steel-reinforced concrete or bellows of the same diameter. Quick drainage of catchment to avoid soil erosion. The bottom part is non-porous, which is conducive to the rapid discharge of catchment water and the prevention of secondary leakage.
3. Technical parameters
Catchment: 65%-75% drainage: 25%-35% main aperture: > 3mm main aperture area: > 7.5mm2 opening ratio: > 8000/m2 (expansion) ring stiffness: > 1.0Kpa.
