геокомпозит слива

Geocomposite Drainl pipe,plastic blind ditch It uses a hydrophilic cloth as filtering medium. It can prevent the filtering layer from being blocked by super fine particles and can be used fro the dehydration of construction concrete and other kinds of slurries. Compared with other ordinary penetration tubes, it does not easily become useless because of being stifled by small particles(normal tubes are blocked in 3 hours of filtering). The high strength terylene silk makes the covered layer combine with the spring circles into one organic body with an omnidirectional filtering function. The water goes into the tube and the sand and soil are blocked out. It could be made into 10m or 20m pieces according to actual demand of project with the other end enclosed with IZl. Penetration, filtering and drainage are done at one turn.Art No.PLD0201PLD0202PLD0203PLD0204PLD0205PLD0206PLD0207PLD0208PLD0209ItemSquare shapeCircular shapeTypeYA7030YA1435YA1550Y1235YB60YB80YB100YB150YB200Outer Size(mm)≥70x30140x35150x50120x35φ60φ80φ100φ150φ200Cannular Size≥40x1040x10x240x20x240x10x2φ25φ45φ55φ80φ120Weight≥350650750600400750100018002900Gap rate≥828285828282848585PressureResistanceFlat rate 5%608250708085804050Flat rate10%110120701101601701407070Flat rate15%15016012513020022018010090Flat rate20%190190160180250280220125120
