Momwe mungasankhire geotextile yapamwamba kwambiri?

Pali mitundu itatu yayikulu ya geotextiles:
1. Geotextile yokhomeredwa ndi singano yopanda nsalu
Malinga ndi zomwe zili, ma geotextiles osapangidwa ndi singano amatha kugawidwa mu polyester geotextiles ndi polypropylene geotextiles;amathanso kugawidwa mu ulusi wautali wa geotextiles ndi ma geotextile afupi-fiber.Geotextile yopanda singano yokhomeredwa ndi singano imapangidwa ndi poliyesitala kapena ulusi wa polypropylene kudzera mu njira ya acupuncture, zomwe zimagwiritsidwa ntchito kwambiri ndi 100g/m2-1500g/m2, ndipo cholinga chachikulu ndi kuteteza malo otsetsereka a mtsinje, nyanja, ndi nyanja, kusefukira kwa madzi. kuwongolera ndi kupulumutsa mwadzidzidzi, ndi zina zotero. Izi ndi njira zothandiza kusunga madzi ndi nthaka ndi kuteteza mapaipi kudzera mmbuyo kusefera.Ma geotextiles afupikitsa amaphatikizanso ma polyester okhomeredwa ndi singano ndi ma polypropylene okhomeredwa ndi singano, onse omwe ndi osalukidwa a geotextiles.Amadziwika ndi kusinthasintha kwabwino, kukana kwa asidi ndi alkali, kukana kwa dzimbiri, kukana kukalamba, komanso kumanga kosavuta.Utali wa fiber geotextiles ndi m'lifupi mwake 1-7m ndi kulemera kwa 100-800g/㎡;amapangidwa ndi polypropylene yamphamvu kwambiri kapena polyester yaitali fiber filaments, yopangidwa ndi njira zapadera, ndipo imakhala yosavala, yosagwedezeka, komanso imakhala ndi mphamvu zowonongeka.
2. Geotextile yophatikizika (nsalu yosalukidwa ndi singano + filimu ya PE)
Ma geotextiles amapangidwa pophatikiza nsalu za polyester zazifupi zokhomeredwa ndi singano zosalukidwa ndi mafilimu a PE, ndipo amagawidwa makamaka kukhala: "nsalu imodzi + filimu imodzi" ndi "nsalu ziwiri ndi filimu imodzi".Cholinga chachikulu cha gulu la geotextile ndi anti-seepage, yoyenera njanji, misewu yayikulu, ngalande, njanji zapansi panthaka, ma eyapoti, ndi ntchito zina.
3. Ma geotextiles osakhala ndi nsalu komanso nsalu
Mtundu uwu wa geotextile umapangidwa ndi nsalu zosalukidwa ndi singano komanso nsalu zapulasitiki.Amagwiritsidwa ntchito makamaka pakulimbitsa maziko ndi zida zoyambira zaumisiri posintha ma coefficient a permeability.
