Kwixesha apho iiprojekthi zeziseko zophuhliso kunye nokukhuselwa kwendalo zijongene neemfuno ezingqongqo zokungangeni kwamanzi, ii-geomembrane zisebenza "njengezinto eziphambili zokulawula ukuvuza kwamanzi"; ukusebenza kwazo kunye nokufaneleka kwazo kumisela ngokuthe ngqo ukhuseleko kunye neenzuzo zendalo zeprojekthi. Isebenzisa iminyaka yobuchule bobuchwephesha obuqokelelweyo kunye nophando olukhethekileyo kunye nophuhliso, iShandong Hongyue Environmental Engineering Co., Ltd. ibone iimveliso zayo ze-geomembrane zamkelwe ngokubanzi kumacandelo angaphezu kweshumi elinesibini - kubandakanya ukugcinwa kwamanzi, ukukhuselwa kwendalo, uthutho, kunye nezolimo. Zihlukile "ngokungangeni kwamanzi okuphezulu, ukumelana nemozulu eqinileyo, kunye nokulula kokufakwa," ezi mveliso zakha ngempumelelo "umgca wokhuselo ongaphantsi komhlaba" oqinileyo kwiiprojekthi ezahlukeneyo zobunjineli.
Umgca wemveliso ye-geomembrane yeShandong Hongyue Environmental ugxile kwi-geomembranes ze-HDPE (High-Density Polyethylene), eziquka iintlobo ezahlukeneyo ezifana neemembranes ezithambileyo, ezithambileyo, kunye nezihlanganisiweyo. Ngobubanzi obuphakathi kwe-0.2 mm ukuya kwi-3.0 mm, ezi mveliso ziyahambelana nomgangatho wesizwe we-GB/T17643-2011. I-coefficient yazo yokungangeni ifikelela kwi-1×10⁻¹² cm/s—elingana nesantya sokuphuma kwamanzi se-0.0001 milliliters yamanzi ngesentimitha yesikwere ngonyaka—idlula kakhulu iimfuno ezisemgangathweni zoshishino zokulawula ukuphuma kwamanzi. Ngaphezu koko, iimveliso zifakwe ii-arhente ezilwa nokwaluphala kunye nezongezo ezimelana ne-UV, ezivumela ukusebenza okuzinzileyo kwiindawo eziqala kwi--70°C ukuya kwi-110°C. Zibonisa ukumelana okunamandla nokugqwala okuvela kwi-acids ezixineneyo kunye ne-alkalis, zinamandla okutyhafa adlula i-18 MPa, kwaye ziyakwazi ukumelana nokwakheka kwejoloji okuntsonkothileyo kunye neemeko zemozulu ezinzima.
Kwicandelo lobunjineli bendalo, ii-geomembrane zisebenza “njengesithintelo esibalulekileyo sokuthintela nokulawula ungcoliseko.” Ii-geomembrane ze-HDPE ze-Hongyue Environmental zisetyenziswe ngempumelelo kwiiprojekthi ezininzi zokulahla inkunkuma—kuquka iSigaba sesiBini seZiko lokuNyangwa kweNkunkuma yeChifeng Central Urban Area kunye neProjekthi yokuVeliswa koMbane weNkunkuma yasekhaya yaseYueyang. Ngokusebenzisa uyilo “lwe-membrane engenakungena kabini kunye ne-geomembrane edibeneyo”, ezi nkqubo zithintela ngokufanelekileyo ukungena kwe-leachate yokulahla inkunkuma, ngaloo ndlela zithintela ungcoliseko lomhlaba kunye namanzi angaphantsi komhlaba. Kwiiprojekthi zezityalo zonyango lwamanzi amdaka, ezi geomembrane zisetyenziswa ekwakhiweni kwamachibi angangeniyo amanzi kunye nezitya zokulahla inkunkuma; ukubekwa esweni okulandelayo okwenziwe kwixesha leminyaka emithathu kutyhile ukuba akukho manqaku okuvuza, ngaloo ndlela kudlala indima ebalulekileyo ekuqinisekiseni ukuba amanzi amdaka acociweyo ayahlangabezana nemigangatho yokukhupha emiselweyo.
Ubunjineli bokugcinwa kwamanzi buyinxalenye yeemeko eziphambili zokusetyenziswa kwee-geomembranes. KwiProjekthi yoKunkcenkceshela iYongtaichuan Irrigation Diversion and Storage Reservoir eJingtai County, kwiPhondo laseGansu, i-geomembrane ye-HDPE enobukhulu obuyi-1.5mm ebonelelwe yiHongyue Environmental Protection idlale indima ebalulekileyo. Ngokusebenzisa uyilo olusebenzisa "ubume bomphezulu ukuphucula ukungqubana," i-membrane ithintela ukutyibilika ecaleni kwethambeka ledama; ngaxeshanye, amandla ayo aphezulu okuxinana ayivumela ukuba ikwazi ukwamkela ukungalingani kwesiseko, ngaloo ndlela iqinisekisa ukhuseleko kunye nokuthembeka kokugcinwa kwamanzi edama. Ngaphezu koko, le mveliso isetyenzisiwe ngempumelelo kwezinye iiprojekthi ezahlukeneyo, kubandakanya izinto ezichasene nokuvuza kwamanzi zeMpuma yeProjekthi yoKujika kwamanzi eSouth-to-North kunye neenkqubo zokuthintela ukuvuza kwamanzi zeBeijing-Shanghai High-Speed Railway. Kwizicelo ezibandakanya ukulungiswa kwemijelo yomlambo kunye nokuqinisa i-embankment, i-geomembrane isebenza umsebenzi ombini-ukubonelela zombini amandla okuthintela ukuvuza kwamanzi kunye nokuhlaziya umva-ngaloo ndlela inciphisa ukukhukuliseka komhlaba kunye nokuphucula uzinzo lweprojekthi iyonke.
Kwicandelo lobunjineli bezothutho, ii-geomembrane zisebenza ngokufanelekileyo njenge "khaka elikhuselayo" kwiindlela ezingaphantsi komhlaba. Ngexesha lokwakhiwa kweendlela ezinkulu nezinkulu, ii-geomembrane zeHongyue Environmental Protection zisetyenziswa njengeeleya ezithintela ukuvuza kwamanzi ukuthintela ukunyuka kweqhwa okubangelwa kukunyuka kwamanzi angaphantsi komhlaba, ngelixa ngaxeshanye zikhusela ukuthamba kwe-subgrade okubangelwa kukungena kwamanzi emvula. Kwiprojekthi yokulungisa umhlaba yeHuanglong Expressway, ii-geomembrane zisetyenziswe kunye nee-geotextiles; olu setyenziso oludibeneyo aluzange luqinisekise kuphela uzinzo lwesakhiwo se-subgrade kodwa lukwaququzelele ukutsalwa kwamanzi kumaleko wezityalo eziphezu kwawo, ngaloo ndlela kufezekiswa iinjongo ezimbini "zokhuseleko lobunjineli kunye nobuhle bendalo."
Kwicandelo lezolimo kunye nezolimo zasemanzini, ii-geomembranes ziye zavela njenge "sixhobo esinamandla sokunciphisa iindleko kunye nokunyusa ukusebenza kakuhle." Ekwakhiweni kwesiza sokuzalisa iimazi ezili-10,500 eTangyin, kwiPhondo laseHenan, i-geomembrane emnyama ye-HDPE ye-Hongyue Environmental Protection enobukhulu obuyi-0.5mm yasetyenziswa kwi-lining ye-biogas digesters engangenisi amanzi. Isebenzisa ukunyibilika kwayo okugqwesileyo kunye nokumelana nokugqwala, i-membrane iqinisekisa ukuqokelelwa ngokufanelekileyo kwe-biogas ngelixa ngaxeshanye ithintela ukuvuza kwenkunkuma yemfuyo kunye nongcoliseko olulandelayo lomhlaba. Kwimisebenzi yokufuya iintlanzi, ii-geomembranes zisetyenziselwa ukukhusela amathambeka kunye ne-lining ukusuka echibini; olu setyenziso lunokunciphisa ukulahleka kwamanzi ngaphezulu kwe-30%, luncede ekuthinteleni ukusasazeka kwezifo zeentlanzi, kwaye ekugqibeleni luncede abalimi bezolimo zasemanzini ekwandiseni ingeniso yabo.
Ngaphandle kweemeko ezikhankanyiweyo apha ngasentla, ii-geomembrane zeHongyue Environmental Protection zikwasetyenziswa kakhulu kwiindawo ezahlukeneyo ezikhethekileyo, kubandakanya iinkqubo ezithintela ukuvuza kwamanzi kwidama leengca zemigodi, ii-linings ze-subway tunnels, kunye nezisombululo zokuthintela ukungenwa kwamanzi kwiigadi zophahla. Le nkampani inikezela ngeenkonzo zokusika ezenzelwe wena ezilungiselelwe iimfuno ezithile zeprojekthi kwaye igcina iqela lobuchwephesha lobuchwephesha ukubonelela ngesikhokelo sokwakha kwindawo. Ngokunikezela ngenkonzo epheleleyo, ukusuka ekuqaleni ukuya ekupheleni—equka yonke into ukusuka “kubonelelo lwezinto” ukuya “kwinkxaso yobugcisa”—Ukhuselo lweNdalo lwaseHongyue luqinisekisa ukusebenza okufanelekileyo kokungavuki kwamanzi kwiprojekthi nganye yobunjineli eyixhasayo. Zisebenzisa izisombululo zazo ezisemgangathweni nezihambelanayo nezihambelana neemeko ezithile, iimveliso ze-geomembrane zeShandong Hongyue Environmental Protection zifikelele kwizixeko ezingaphezu kwama-40 ezinkulu neziphakathi kulo lonke elaseTshayina, kunye nokuthunyelwa kwamanye amazwe okuya kwiindawo ezifana neYurophu, iMelika, ne-Australia. Njengoko ukhuseleko lokusingqongileyo kunye neeprojekthi zeziseko zophuhliso ziqhubeka zihambela phambili, uKhuseleko lokusingqongileyo lwaseHongyue luya kuhlala lugxile ekuphuculeni ubuchwepheshe obuchasene nokuvuza kwamanzi—ukuqinisa “imigca yokhuselo engaphantsi komhlaba” kwinani elikhulayo leeprojekthi—ngaloo ndlela kuququzelelwa uphuhliso oludibeneyo lweziseko zophuhliso eziluhlaza kunye nokugcinwa kwendalo.
