Kupanga ma geotextile a silika aatali (aafupi), nsalu yosalowa udzu, matumba a zachilengedwe, ma geomembrane, ma geomembrane a composite, bolodi losalowa madzi la PE/PVC/EVA/ECB, bulangeti losalowa madzi la GCL Sodium bentonite, net yophatikizana, bolodi lotulutsa madzi, geogrid, bolodi la thovu lotsekedwa, geocell, geonet, rabara waterstop geotextile ili ndi zosefera zabwino kwambiri, mapaipi otulutsa madzi, chitetezo, nthiti zolimbitsa, komanso chitetezo chachitetezo. Ili ndi mawonekedwe opepuka, mphamvu yayikulu yopondereza, kulola madzi kulowa bwino, kukana kutentha, kukana kuzizira, kukana ukalamba komanso kukana dzimbiri. Kugwiritsa ntchito zida zoyeserera za geotechnical kunayamba m'ma 1950, ndipo geotextile ya ku China ndi imodzi mwa Dongosolo la Zaka Zisanu ndi Chisanu la China. Mu 1998, China idakhazikitsa mfundo ya "Geosynthetic Staple Fiber Needle-punched Nonwoven Geotextile", ndipo geotextile yagwiritsidwa ntchito kwambiri m'mafakitale angapo. Geotextile yofunika kwambiri ili ndi zinthu zitatu zotsatirazi:
1. Singano yopanda ulusi, tsatanetsatane ndi chitsanzo 100g /m2-600g/m2 Sankhani mwachisawawa pakati. Chofunika kwambiri ndi ulusi wokhazikika wa polyester kapena ulusi wokhazikika wa polypropylene. Umapangidwa motsatira njira yoboola singano. Ntchito yake ndi iyi: kuteteza mitsinje, nyanja, nyanja ndi mitsinje, kukonzanso nyanja, doko, kuwongolera kusefukira kwa madzi m'sitima, kupulumutsa ndi kuthandiza pakagwa masoka, ndi zina zotero. Mapulojekiti a uinjiniya ndi njira yofunika kwambiri yotetezera chilengedwe ndikupewa mapaipi kutengera kusefedwa kumbuyo.
2. Nsalu yosalukidwa ndi singano ndi PE. Zinthu zofunika kwambiri za nembanemba yopangidwa ndi geotextile ndi polyester staple fiber yokhala ndi singano yopangidwa ndi singano yokhala ndi mulifupi waukulu, PE. Nembanembayo imapangidwa ndi mtundu wa composite, ndipo kukula kwake ndi kosalowa madzi. Ndi yoyenera njanji, misewu yothamanga, kumanga ngalande, masiteshoni a sitima zapamtunda, ma eyapoti ndi mapulojekiti ena auinjiniya.
3. Nsalu yosalukidwa ndi geotextile yopangidwa ndi nsalu yopangidwa ndi polypropylene, kuphatikizapo nsalu yosalukidwa ndi polypropylene, ulusi wolukidwa ndi ulusi wopangidwa ndi polyester, nsalu yosalukidwa ndi pulasitiki yopangidwa ndi manja, yoyenera kugwiritsa ntchito zida zolimbitsa maziko ndi zomangamanga kuti zisinthe momwe madzi amalowera. Staple fiber geotextile Staple fiber needle geotextile imapangidwa ndi polyester staple fiber ngati zopangira, ndipo imapangidwa ndikukonzedwa pomaliza ndikuyika makina ndi zida, kuphatikiza makina ndi zida zoboola singano.
Zinthu Zake: Chogulitsachi chili ndi makhalidwe abwino kwambiri monga kukana dzimbiri, kukana dzimbiri, kukana ukalamba, mphamvu yolimba, mawonekedwe okhazikika komanso kusefa bwino.
Ntchito zazikulu: Ntchito zazikulu ndi kukonza, kuteteza, kuteteza kutayira madzi ndi mapaipi otayira madzi m'mapulojekiti aukadaulo. Amagwiritsidwa ntchito kwambiri m'mapulojekiti osamalira madzi, misewu, njanji ndi mafakitale ena.
