Ma Geotextiles Amphamvu Akuluakulu Okhazikika Okhazikika
Weave geotextile imapangidwa ndi ulusi wa polypropylene, polypropylene ndi polyethylene lathyathyathya ngati zida zopangira, ndipo imakhala ndi mitundu iwiri ya ulusi wofanana (kapena ulusi wosalala).Gulu limodzi limatchedwa ulusi wa warp motsatira njira yotalikirapo ya nsalu (komwe nsaluyo imayendera) Kukonzekera kopingasa kumatchedwa weft.Ulusi wokhotakhota ndi ulusi woluka amalukidwa munsalu yokhala ndi zida zosiyanasiyana zoluka ndi njira, zomwe zimatha kukulukidwa mu makulidwe ndi makulidwe osiyanasiyana malinga ndi magawo osiyanasiyana ogwiritsira ntchito, ndikukhazikika bwino.

Zogulitsa Zamankhwala
1. Mphamvu yayikulu, kutalika kochepa, kukana kukalamba, kosavuta kung'amba
2. Pewani udzu, tizilombo, pewa kukokoloka, pewa kukokoloka kwa nthaka
3. Yesetsani kuteteza mchenga ndikulola madzi ndi mpweya kudutsa
4. Acid ndi alkali kukana, kuzizira kwambiri kuzizira, ndi kutsutsa kwamphamvu kwa nyengo
Kugwiritsa ntchito
1. Amagwiritsidwa ntchito m'mapulojekiti a miyala monga misewu yayikulu, njanji, mabwalo a ndege, madamu amiyala, mabwalo otsekera, makoma osungira, kubweza kumbuyo, malire, ndi zina zotero, kufalitsa kupanikizika kwa nthaka kuti awonjezere nthaka modulus, kuchepetsa kutsetsereka kwa nthaka, ndi kukonza bata.
2. Pewani mpanda kuti zisakulidwe ndi mphepo, mafunde, mafunde ndi mvula, ndipo ugwiritsidwe ntchito poteteza mabanki, kuteteza kutsetsereka, kuteteza pansi, ndi kupewa kukokoloka kwa nthaka.
3. Amagwiritsidwa ntchito ngati fyuluta ya mizati, madamu, mitsinje ndi miyala ya m'mphepete mwa nyanja, malo otsetsereka a nthaka, ndi makoma otchinga kuti mchenga ndi nthaka zisadutse, ndikulola madzi kapena mpweya kudutsa momasuka.
Zindikirani
1. Geotextiles akhoza kudulidwa kokha ndi mpeni wa geotextile (mbeza mpeni).Ngati kudula kwachitika pamalopo, njira zodzitetezera zapadera ziyenera kuchitidwa pazinthu zina kuti mupewe kuwonongeka kosafunikira komwe kumachitika chifukwa chodula ma geotextiles;
2. Panthawi imodzimodziyo pamene geotextile imayikidwa, njira zonse zofunika ziyenera kuchitidwa kuti zisawonongeke pazinthu zomwe zili pansipa;
3. Mukayika ma geotextiles, samalani musalole zinthu zina monga miyala, fumbi lambiri kapena chinyezi chomwe chingawononge geotextile, kutsekereza zotayira kapena zosefera, kapena kupangitsa kulumikizana kotsatira kukhala kovuta;
4. Pambuyo poika, yang'anani pamwamba pa geotextile kuti muwone malo onse owonongeka, chizindikiro ndi kukonza, ndipo onetsetsani kuti palibe zinthu zina pamtunda zomwe zingayambitse kuwonongeka, monga singano zosweka;
5. Kulumikizana kwa geotextiles kuyenera kutsata malamulo otsatirawa: Nthawi zonse, sipadzakhala kugwirizana kopingasa pamtunda (zolumikizira sizidzadutsana ndi malo otsetsereka), pokhapokha ngati kukonzanso kumapangidwa.
6. Ngati ma suture agwiritsidwa ntchito, ma sutures ayenera kupangidwa ndi zofanana kapena zambiri kuposa geotextile material, ndipo ma sutures ayenera kupangidwa ndi mankhwala osagwirizana ndi uv.Payenera kukhala kusiyana koonekera bwino kwamitundu pakati pa ma sutures ndi ma geotextiles kuti athe kuyendera.
7. Chisamaliro chapadera chiyenera kuchitidwa panthawi yoikapo kuonetsetsa kuti palibe miyala yochokera ku dothi kapena miyala yomwe imalowa pakati pa geotextile.
