Chifukwa cha kukula kwa chuma cha dziko lathu komanso kusintha kwa miyoyo ya anthu, ma nembanemba a geotextile agwiritsidwa ntchito kwambiri. Komabe, ngakhale pamtundu womwewo wa nembanemba ya geotextile, nthawi yogwirira ntchito imatha kusiyana kwambiri kutengera malo enieni ndi momwe imagwirira ntchito. Ndiye, kodi tingagwiritse ntchito bwanji bwino nembanemba za geotextile kuti tiwonjezere nthawi yogwirira ntchito yawo? Lero, tiyeni tiwone njira zofunika kuzitsatira pogwiritsa ntchito zipangizozi.
Mukamagwiritsa ntchito nembanemba za geotextile, ndibwino kwambiri kuchepetsa kukhudzana ndi kuwala. Ngati nembanembayo ikhoza kutetezedwa bwino ku kuwala nthawi yonse yomwe ikugwira ntchito, izi zimapereka chitsimikizo chachikulu chowonjezera nthawi yake yonse.
Pakuyika, nembanemba iyenera kuyikidwa pang'onopang'ono, zomwe zimapangitsa kuti pakhale mpata wokulirapo ndi kupindika; kutambasula kwambiri sikuloledwa. Kusinthasintha kwa kutentha ndi kukhazikika kwa nthaka kungayambitse kuti nembanemba zolimba zisweke mosavuta; kuyala nembanembayo pang'onopang'ono kumachepetsa zoopsa zotere. Kuyika kuyenera kupitirira pansi pa phiri—kuchokera pamwamba mpaka pansi—kuti kuchepetse kuchuluka kwa mipata yopingasa. M'lifupi mwa mapepala olumikizana pakati pa nembanemba yoyandikana nayo muyenera kukwaniritsa miyezo yokhazikika: mipata yolumikizidwa iyenera kukhala yosachepera 10 cm mulifupi, pomwe mipata yolumikizidwa iyenera kukhala yosachepera 15 cm mulifupi.
Ogwira ntchito yomanga ayenera kuvala nsapato zofewa pamene akugwira ntchito; kuyenda pa nembanemba atavala nsapato zolimba kapena nsapato zokhala ndi misomali yowonekera n'koletsedwa kwambiri. Zida zomanga ziyenera kusamalidwa mosamala kuti zisagwe kwambiri. Makina olemera ndi magalimoto olemera saloledwa kuyendetsa mwachindunji pamwamba pa nembanemba ya geotextile; ngati ntchito zotere ndizofunikira, zigawo zoteteza kwakanthawi—monga matabwa amatabwa kapena matumba a mchenga—ziyenera kuyikidwa pansi kaye. Kuphatikiza apo, nyengo panthawi yomanga iyenera kuyang'aniridwa mosamala. Ntchito zoyika ndi kulumikiza ndizoletsedwa panthawi yamvula kapena chifunga, mphepo ikapitirira Mphamvu 5, kapena kutentha kwa malo ozungulira kukatsika pansi pa 5°C, kuti nembanemba isang'ambike ndi mphepo kapena kuonetsetsa kuti ubwino wa weld ukukwaniritsa miyezo yofunikira.
Ntchito ya uinjiniya ikangoyamba kugwira ntchito, njira yowunikira nthawi ndi nthawi iyenera kukhazikitsidwa. Chisamaliro chapadera chiyenera kuperekedwa kumadera ofunikira monga mipata yolumikizira, malo osinthira mapiri, ndi madera omwe madzi amatha kusonkhana, kuti aone ngati pali zizindikiro zilizonse za kuwonongeka, matuza, ming'alu yomwe imabwera chifukwa cha kukhazikika kwa nthaka, kapena kulowa kwa mizu. M'dera losalowa madzi, zochita monga kuyendetsa milu, kuboola, kapena kukoka zinthu zolimba ndizoletsedwa kuti zipewe kuwonongeka mwangozi komwe kumachitika chifukwa cha zochita za anthu.
Pa ntchito zapadera—monga malo otayira zinyalala kapena maiwe osungiramo mankhwala—ndikofunikira kusankha ma nembanemba a geotextile omwe adapangidwa makamaka kuti azitha kukana dzimbiri komanso kupewa kukalamba, komanso kuchita mayeso a magwiridwe antchito nthawi ndi nthawi pa nembanemba. Kuwonongeka kulikonse komwe kwapezeka kuyenera kukonzedwa nthawi yomweyo kuti kupewe kutayikira kufalikira ndikuwonetsetsa kuti dongosolo losalowa madzi limakhala lolimba komanso lolimba kwa nthawi yayitali. Akatswiri amakampani akugogomezera kuti, pankhani yogwiritsa ntchito ma geomembrane, palibe tsatanetsatane womwe ndi wochepa kwambiri; mbali iliyonse imakhudza mwachindunji ubwino wa polojekiti komanso chitetezo cha chilengedwe. Opanga ndi ogwiritsa ntchito ayenera kutsatira kwambiri miyezo ndi miyezo yokhazikitsidwa, kukhazikitsa zowongolera zonse panthawi yonseyi, kuti agwiritse ntchito bwino ma geomembrane ndikulimbitsa "njira yotetezeka" ya polojekiti.
