Changhong Plastic Blind Drain

Product survey

Plastic blind drain is frame structure that is formed by mutual joining of silks of modified polypropylene after melting and a layer of geotechnical cloth is wrapped on its outside. Clean water after filtering by geotechnical cloth enters plastic blind drain and is discharge. Section of permeable pipe can be made into various shapes according to project need, mainly including rectangle and circle.

Product features

Plastic blind drain itself is formed by melting multiple modified plastic silks with strong toughness, so it hasn't the possibility of being broken and damaged. Clearance rate of section still keeps above 60% under the pressure of 250kPa, water passing clearance still exists an 10-15% of hole clearance still exists even large pressure is exerted, and repeatability is good.

Average surface opening rate of plastic blind drain reaches 90-95%, much higher than that of other similar products. It can collect permeation water in soil effectively and discharge the water timely.

Plastic blind drain is three-dimensional solid net shape combination by filter film and modified polypropylene made of corrosion resistance fiber, has the feature of never degradation in soil or water, uses aging resistance formula and has the feature of without quality change forever.

Filter film of plastic blind drain can be selected according to different soil texture conditions so as to meet project needs.

Plastic blind drain has light density and is very convenient for site construction and installation, so construction efficiency improves quickly.
