I-geosynthetic clay liner (GCL) iwuhlobo lwempahla ye-geosynthetic esetshenziswa kubunjiniyela bomphakathi kanye nezicelo zemvelo. Iwumugqa oyinhlanganisela ohlanganisa ungqimba lobumba lwe-bentonite oluhlanganiswe phakathi kwezingqimba ezimbili ze-geotextile. Izendlalelo ze-geotextile zinikeza ukuqiniswa nokuvikela ubumba lwe-bentonite, luthuthukisa ukusebenza kwalo njengesithiyo ngokumelene namanzi, amagesi, kanye nokungcola.
Iubumba lwe-geosynthetic olufakwe inalitii-liner wuhlobo oluthile lwe-GCL olukhiqizwa kusetshenziswa inqubo yokubhoboza inaliti. Le nqubo ihilela ukuvala ngomshini izingqimba ze-geotextile kanye ne-bentonite kusetshenziswa izinaliti ezinemihlaba, okwenza ulayini oyinhlanganisela oqinile noqinile. I-GCL ebhotshozwe inaliti iklanyelwe ukuhlinzeka ngokusebenza okuhle kakhulu kwe-hydraulic, amandla aqinile aphezulu, nokumelana nokubhoboza, okuyenza ifanelekele uhla olubanzi lwezinhlelo zokusebenza.
Enye yezinzuzo ezibalulekile zama-GCL ahlatshwe yenaliti yikhono lawo lokuhlinzeka ngokuqukatha okusebenzayo nokuvikelwa kwemvelo kumaphrojekthi ahlukahlukene wobunjiniyela nokwakha. Lawa malayini avame ukusetshenziswa ezinhlelweni zamalayini okulahlwa kwemfucuza, ukusebenza kwezimayini, ujenga lwamachibi namachibi, kanye nezinye izinhlelo zokusebenza zokuqukatha imvelo. Ama-GCL abhontshiwe yenaliti aphinde asetshenziswe kumaphrojekthi wobunjiniyela bamanzi, njengemisele kanye nolwelwesi lwamachibi, kanye nasekwakhiweni kwemigwaqo nojantshi ukuze kunqandwe ukuguguleka nokuqiniswa kwemithambeka.
Idizayini eyingqayizivele nokwakhiwa kwama-GCL abhontshiwe inaliti kuwenza aphumelele kakhulu ekuvimbeleni ukufuduka koketshezi, amagesi, nokungcola emhlabathini. Isendlalelo sobumba be-bentonite ku-GCL siyakhukhumala lapho sithintana namanzi, sidala umgoqo wokuzivala ovimbela ukudlula kwamanzi kanye nokungcola. Lesi sakhiwo senza ama-GCL abhontshiswe inaliti abe yinketho efanelekile yokuvikela imvelo kanye nezicelo zokuqukatha, lapho ukuvimbela ukufuduka kwama-leachate kanye nokungcoliswa kwamanzi angaphansi komhlaba kubalulekile.
Ngaphezu kwezinzuzo zabo zemvelo, ama-GCL abhontshiwe inaliti anikeza izinzuzo ezimbalwa mayelana nokufakwa kanye nokusebenza kahle kwezindleko. Imvelo engasindi futhi eguquguqukayo yalawa malayini iwenza kube lula ukuwaphatha nokuwafaka, okunciphisa isikhathi sokwakha nezindleko zabasebenzi. Ama-GCL abhontshiwe inaliti angenziwa ngokwezifiso kalula ukuze alingane nezidingo ezithile zamaphrojekthi ahlukene, okuvumela ukufakwa okusebenzayo nokunembayo.
Ngaphezu kwalokho, ukusebenza kwesikhathi eside nokuqina kwama-GCL ahlatshwe yenaliti kuwenza abe yisixazululo esingabizi kakhulu sokuvikelwa kwemvelo kanye nokuvinjwa. Lawa ma-liner anomlando ofakazelwe wokumelana nezimo zemvelo ezinzima nokugcina ubuqotho bawo ngokuhamba kwesikhathi, okunciphisa isidingo sokunakekelwa njalo nokushintshwa.
Sekukonke, iubumba lwe-geosynthetic olufakwe inalitiI-liner iyisixazululo esiguquguqukayo nesithembekile sohlu olubanzi lobunjiniyela bomphakathi kanye nezicelo zemvelo. Idizayini yayo eyingqayizivele, izakhiwo ezisebenzayo zokuqukatha, kanye nokuphumelela kwezindleko kuyenza ibe yingxenye ebalulekile ekwakhiweni kwesimanje kanye namaphrojekthi okuvikela imvelo. Kungakhathaliseki ukuthi isetshenziselwa ulayini wokulahla imfucumfucu, ukusebenza kwezimayini, ubunjiniyela bamanzi, noma ukulawula ukuguguleka, ama-GCL abhobozwe inaliti adlala indima ebalulekile ekuqinisekiseni ukusimama nokuphepha kwemvelo kwengqalasizinda ehlukahlukene kanye namaphrojekthi okuthuthukiswa.
