Esikhathini lapho imiklamo yengqalasizinda kanye nokuvikelwa kwemvelo ibhekene nezidingo eziqinile zokungangeni kwamanzi, ama-geomembrane asebenza “njengezinto eziyinhloko zokulawula ukuvuza kwamanzi”; ukusebenza kwawo kanye nokufaneleka kwawo kunquma ngqo ukuphepha kanye nezinzuzo zemvelo zephrojekthi. Isebenzisa iminyaka yobuchwepheshe obuqongelelwe kanye nocwaningo nokuthuthukiswa okuqondene nezimo ezithile, iShandong Hongyue Environmental Engineering Co., Ltd. ibone imikhiqizo yayo ye-geomembrane isetshenziswa kabanzi emikhakheni engaphezu kweshumi nambili—kufaka phakathi ukongiwa kwamanzi, ukuvikelwa kwemvelo, ezokuthutha, kanye nezolimo. Ihlukaniswa “ngokungangeni kwamanzi okuphezulu, ukumelana nesimo sezulu okuqinile, kanye nokulula kokufakwa,” le mikhiqizo yakha ngempumelelo “umugqa wokuzivikela ongaphansi komhlaba” oqinile wezinhlobo ezahlukene zamaphrojekthi obunjiniyela.
Umugqa womkhiqizo we-geomembrane we-Shandong Hongyue Environmental ugxile kuma-geomembrane e-HDPE (High-Density Polyethylene), ahlanganisa izinhlobo ezahlukene ezifana nama-membrane abushelelezi, athambile, kanye nahlanganisiwe. Ngobubanzi obukhulu obungu-0.2 mm kuya ku-3.0 mm, le mikhiqizo ihambisana nendinganiso kazwelonke ye-GB/T17643-2011. I-coefficient yabo yokungangeni ifinyelela ku-1 × 10⁻¹² cm/s—okulingana nesilinganiso sokuvuza kwamanzi esingamamililitha angu-0.0001 amanzi ngesentimitha lesikwele ngonyaka—esidlula kakhulu izidingo ezijwayelekile zemboni zokulawula ukuvuza kwamanzi. Ngaphezu kwalokho, imikhiqizo ifakwe ama-ejenti okulwa nokuguga kanye nezithasiselo ezingamelana ne-UV, okwenza ukusebenza okuzinzile ezindaweni ezisukela ku--70°C kuya ku-110°C. Ibonisa ukumelana okunamandla nokugqwala okuvela kuma-acid agxilile kanye nama-alkali, inamandla okubamba adlula i-18 MPa, futhi iyakwazi ukumelana nokwakheka okuyinkimbinkimbi kwe-geological kanye nezimo zezulu ezinzima.
Emkhakheni wobunjiniyela bezemvelo, ama-geomembrane asebenza “njengesithiyo esibalulekile sokuvimbela nokulawula ukungcola.” Ama-geomembrane e-HDPE e-Hongyue Environmental asetshenziswe ngempumelelo kumaphrojekthi amaningi okulahla udoti—kufaka phakathi iSigaba II seChifeng Central Urban Area Waste Treatment Center kanye neYueyang Domestic Waste Incineration Power Generation Project. Ngomklamo “we-membrane engangenwa kabili kanye ne-geomembrane ehlanganisiwe”, lezi zinhlelo zivimba ngempumelelo ukungena kwe-leachate yokulahla udoti, ngaleyo ndlela zivimbele ukungcoliswa komhlabathi kanye namanzi angaphansi komhlaba. Emaphrojekthini ezitshalo zokwelashwa kwamanzi angcolile, la ma-geomembrane asetshenziswa ekwakhiweni kwamachibi angangeni amanzi kanye nezitsha zokuchitheka; ukuqapha okulandelayo okwenziwe esikhathini seminyaka emithathu kwembule ukuthi akukho maphuzu okuvuza, ngaleyo ndlela kudlala indima ebalulekile ekuqinisekiseni ukuthi amanzi angcolile ahlanziwe ahlangabezana nezindinganiso zokukhishwa kwendle ezisemthethweni.
Ubunjiniyela bokulondolozwa kwamanzi bungenye yezimo eziyinhloko zokusetshenziswa kwama-geomembrane. Kuphrojekthi Yokunisela Yokuchezukisa Nokugcina Isitoreji saseYongtaichuan eJingtai County, eSifundazweni saseGansu, i-geomembrane ye-HDPE enobuthi obuyi-1.5mm enikezwe yi-Hongyue Environmental Protection idlale indima ebalulekile. Ngomklamo osebenzisa "ukuthungwa kobuso ukuze kuthuthukiswe ukungqubuzana," i-membrane ivimbela ukushelela emithambekeni yedamu; ngasikhathi sinye, amandla ayo aphezulu okuthamba ayivumela ukuthi ikwazi ukwamukela ukungalingani kwesisekelo, ngaleyo ndlela iqinisekise ukuphepha nobuqotho bokugcinwa kwamanzi edamu. Ngaphezu kwalokho, lo mkhiqizo usetshenziswe ngempumelelo kwamanye amaphrojekthi ahlukahlukene, kufaka phakathi izingxenye ezivimbela ukuvuza kwamanzi ze-Eastern Route ye-South-to-North Water Diversion Project kanye nezinhlelo ezivimbela ukuvuza kwamanzi ze-Beijing-Shanghai High-Speed Railway. Ezinhlelweni ezibandakanya ukulungiswa kwemisele yomfula kanye nokuqinisa i-embankment, i-geomembrane isebenza umsebenzi ophindwe kabili—ihlinzeka kokubili ngamakhono okuvimbela ukuvuza kanye nokuhlunga okuphambene—ngaleyo ndlela inciphisa ukuguguleka kwenhlabathi futhi ithuthukise ukuzinza kwephrojekthi iyonke.
Emkhakheni wobunjiniyela bezokuthutha, ama-geomembrane asebenza kahle “njengesivikelo” semigwaqo engaphansi komhlaba. Ngesikhathi sokwakhiwa kwemigwaqo emikhulu kanye nezitimela, ama-geomembrane e-Hongyue Environmental Protection asetshenziswa njengezendlalelo ezivimbela ukuvuza kwamanzi ukuze kuvinjelwe ukukhuphuka kweqhwa okubangelwa ukwanda kwamanzi angaphansi komhlaba, kuyilapho ngesikhathi esifanayo evikela ukuthamba kwe-subgrade okubangelwa ukungena kwamanzi emvula. Kuphrojekthi yokuhlobisa i-Huanglong Expressway, ama-geomembrane asetshenziswa kanye nama-geotextiles; lolu hlelo oluhlanganisiwe aluzange luqinisekise kuphela ukuzinza kwesakhiwo se-subgrade kodwa futhi lwenze kube lula ukukhipha amanzi engqimbeni yezitshalo eziphezu kwayo, ngaleyo ndlela kufezwe izinhloso ezimbili “zokuphepha kobunjiniyela kanye nobuhle bemvelo.”
Emikhakheni yezolimo kanye nokufuywa kwezinhlanzi, ama-geomembrane avele “njengethuluzi elinamandla lokunciphisa izindleko nokukhulisa ukusebenza kahle.” Ekwakhiweni kwesikhungo sokuzalela izinkomo esingu-10,500 eTangyin, eSifundazweni saseHenan, i-geomembrane emnyama ye-HDPE ye-Hongyue Environmental Protection engu-0.5mm ubukhulu yasetshenziswa ukuze kuvikelwe ukuvuza kwe-biogas digesters. Isebenzisa ukushibilika kwayo okuhle kakhulu kanye nokumelana nokugqwala, i-membrane iqinisekisa ukuqoqwa okuphumelelayo kwe-biogas ngenkathi ngesikhathi esifanayo ivimbela ukuvuza kwemfucuza yezilwane kanye nokungcola okulandelayo kwenhlabathi. Emisebenzini yokulima izinhlanzi, ama-geomembrane asetshenziselwa ukuvikela imisele kanye nokufakwa phansi kwechibi; lolu hlelo lokusebenza lunganciphisa ukulahlekelwa kwamanzi ngaphezu kuka-30%, lusize ekuvimbeleni ukusabalala kwezifo zezinhlanzi, futhi ekugcineni lusize abalimi bezinhlanzi ekwandiseni imali yabo engenayo.
Ngaphandle kwezimo ezishiwo ngenhla, ama-geomembrane e-Hongyue Environmental Protection nawo asetshenziswa kabanzi emikhakheni ehlukahlukene ekhethekile, okuhlanganisa izinhlelo zokulwa nokuvuza kwamanzi emachibini asemayini, imigqa yemigudu yesitimela esingaphansi komhlaba, kanye nezixazululo zokuvimbela amanzi ezingadini zophahla. Le nkampani inikeza izinsizakalo zokusika ezenziwe ngokwezifiso ezenzelwe izidingo ezithile zephrojekthi futhi igcina ithimba lobuchwepheshe eliqeqeshiwe ukuze linikeze isiqondiso sokwakha endaweni. Ngokunikeza insizakalo ephelele, kusukela ekuhlinzekweni kwezinto ezibonakalayo kuya "ekusekelweni kobuchwepheshe" - i-Hongyue Environmental Protection iqinisekisa ukusebenza okuhle kakhulu kokulwa nokuvuza kwamanzi kuyo yonke iphrojekthi yobunjiniyela eyisekelayo. Isebenzisa izixazululo zayo zekhwalithi ezihambisanayo nezihambisana nezimo ezithile, imikhiqizo ye-geomembrane ye-Shandong Hongyue Environmental Protection ifinyelele emadolobheni amakhulu naphakathi angaphezu kwama-40 kulo lonke elaseShayina, kanye nokuthunyelwa kwamanye amazwe kusakazekela ezifundeni ezifana neYurophu, iMelika, ne-Australia. Njengoba siqhubeka phambili, njengoba amaphrojekthi okuvikela imvelo kanye nengqalasizinda eqhubeka nokuthuthuka, i-Hongyue Environmental Protection izohlala igxile ekuthuthukiseni ubuchwepheshe obuvimbela ukuvuza kwamanzi—ukuqinisa “imigqa yokuvikela engaphansi komhlaba” ukuze kuthuthukiswe inani elikhulayo lamaphrojekthi—ngaleyo ndlela kube lula ukuthuthukiswa okusebenzisanayo kwengqalasizinda eluhlaza kanye nokulondolozwa kwemvelo.
