Kwindibano yendalo esingqongileyo kunye noluntu, ukulawula ukufuduka kukamanzi kubalulekile kwiiprojekthi ezinje ngokuzala komhlaba, iindawo zokugcina amanzi kunye neenkqubo ze-appral. Isixhobo esinye esidlala indima ebaluleke kakhulu kwezi ziceloI-Geosynthetic Clay Liner(I-GCL). Eli nqaku libonisa ukukhohlisaI-Geosynthetic Clay Liners, echaza ubume babo, ukusebenza kwabo, kwaye kutheni bekhetha ukhetho olukhethiweyo lwe-hydraulic.
UkuqondaI-Geosynthetic Clay Liners
AI-Geosynthetic Clay LinerNgaba izinto ezihlanganisiweyo zokudibanisa i-geotextantis, i-Bentotite Clay, kwaye ngamanye amaxesha yejomem. I-Contrement yeCore-Sodium Bentotite-yindawo yokudofiswa kakhulu efihlakeleyo xa ihlanjwe, yenza umqobo ophantsi kakhulu. I-SANDWICTED phakathi kweendawo ze-geotextextas, olu calulo luqinisekisa ukuqina ngelixa lugcina ukutshintsha.
Ukukhohlisa kweI-Geosynthetic Clay LinerIbhekisa kubuchule bayo bokuthintela ukuhamba kwamanzi. Ukulinganiswa ngokubhekisele kwi-Hydraulic Medition (≤1 × 10º cm / s ye-GCLS), le mpahla yenza i-GCLS isebenze ngokukhethekileyo ekuthinteleni izakhiwo ezixhaphakileyo.
Kutheni kubalulekile kuzoI-Geosynthetic Clay Liners
Ukungqinwa kukuchazwa kwempawu zalo naliphi na isithintelo se-hydraulic. KubaI-Geosynthetic Clay Liners, ukungqubana okuphantsi kuqinisekisa:
I-1.NENCEALONOROORNOROORN: Thintela iLeachate evela kumhlaba wokugcina umhlaba wine wamanzi aphantsi komhlaba.
Ingqibelelo yeqonga: Ukunciphisa ukhukuliseko kumadama okanye ii-canas ngokunciphisa i-joyiti yamanzi.
Ukuthobela ukutya: Hlangabezana nemigangatho engqongqo yeenkqubo zezixhobo kwiiprojekthi zeshishini.
Umthamo wokudumba wesodium Bentotite qhosha apha. Xa i-hydding, udongwe lwandiswa ukuya kuthi ga kwi-15 ivolumu yayo eyomileyo, izalisa i-voids kunye nokwenza umaleko ongafanelekanga. Kwanaphantsi koxinzelelo oluphezulu lwe-hydraulic, ifakwe ngokufanelekileyoI-Geosynthetic Clay LinersGcina intsebenzo yabo.
Izinto ezichaphazela ingqumbo yeI-Geosynthetic Clay Liners
Ngelixa i-GCLS inokuthenjwa, ukuguquka kwabo kungahluka ngokusekwe:
Umxholo we -Omostinya: I-Bentotite eyomileyo inomsebenzi ophakamileyo; I-hydration iyenza iipropathi zetywina.
I-onfowsion kunye nevaliwe: Uxinzelelo olwaneleyo ngexesha lokufakwa luqinisekisa ukusasazwa kodongwe olulinganayo.
I-Shechemical: Ukuvezwa kweekhemikhali zobundlobongela (umzekelo, ulwelo oluphezulu) lunokunciphisa amandla okudumba.
Uvavanyo phantsi kweemeko ezithile zendawo kubalulekile ukuqinisekisa aI-Geosynthetic Clay Linerukusebenza kwe-s.
Izicelo zokuzifaka i-fient capI-Geosynthetic Clay Liners
I-1.Nandill Caps kunye neziseko: I-GCLS isetyenziswa ngokubanzi njengeebhokhwe zesibini phantsi kweJomembranes zinenkunkuma eyingozi.
Imisebenzi yokuSebenza: Banqanda i-acid ye-acid avela kwi-colosystem yendalo.
3. Iziseko zophuhliso lwamanzi: Kwi-cansals okanye ichibi, i-GCLS inciphisa ilahleko yendawo yokulahleka.
Xa kuthelekiswa nee-liners zemveli eziqokelelweyo (ii-CCLs),I-Geosynthetic Clay LinersNika ufakelo olukhawulezileyo, ukunciphisa ubukhulu, kunye nokungaguquki okungaguqukiyo.
Ulondolozo kunye nokuLondolozwa kweI-Geosynthetic Clay Liners
Ukufakwa ngokufanelekileyo kubalulekile. Iziphumo okanye ezingaphelelanga ngaphezulu kwe-GCL Roll zinokulalanisa. Ukuhamba kwexesha, i-Bentotite ngokwakho imibalabala-mbala omncinci, kodwa ukuhlolwa rhoqo kuyacetyiswa. Xa ukhuselekile kwi-UV ekubonakaliseni kunye noxinzelelo lwendlela, aI-Geosynthetic Clay LinerIngahlala ishumi leminyaka.
Ikamva leI-Geosynthetic Clay Liners
Ukuqhubela phambili kwesayensi yezinto ezibonakalayo kukuphucula ukusebenza kwe-GCL. I-Innovations njenge-polymer ephuculweyo okanye i-hybrid liners (ukudibanisa i-GCLS nge-GCOMMROS) kukuphucula ukunganyangeki kweekhemikhali kunye nokuziqhelanisa neemeko ezithile.
Ukuqukumbela
I-Geosynthetic Clay Linerslilitye lembombo lezi nkqubo zisebenza zanamhlanje, ukuhambisa ulawulo olungenakuthelekiswa nanto. Ukudityaniswa kwabo kwe-gesynthetics kunye nodongwe lwendalo luzisa izisombululo ezisebenzayo, ezisebenzayo ze-Eco Njengamashishini abeka phambili uzinzo, imfuno yokusebenza kakuhleI-Geosynthetic Clay Linersiya kukhula kuphela.
Ngokuqonda ngenkqubo yabo yendlela yokusebenza kunye nokusetyenziswa, iinjineli zinokuhambisa i-GCLs ngokufanelekileyo, ekuqinisekiseni iziseko ezikhuselekileyo neziqinileyo zehlabathi.
