Uxinaniso oluphezulu lwe-polyethylene geomembrane lusetyenziswa ikakhulu kwiindawo zokulahla inkunkuma, amachibi embonakalo yomhlaba, kunye namachibi.Inqanaba leengcambu zasemaphandleni libekwe phantsi, kwaye i-design iyonke yophahla lwe-membrane inobunzima bomgangatho okhuselayo, ngoko ke umngcipheko wokuvuza awuphezulu.Nangona kunjalo, ukugaywa kweendonga zesakhiwo sekonkile kulwakhiwo lweprojekthi yokuqala, kwaye kukho ubunzima obukhulu obubini ekwakhiweni: obunye kukugalela inwebu engenakungeneka eludongeni lwesitora esine-4m ukuphakama.I-membrane engabonakaliyo ithwala ngokukhawuleza impembelelo yamandla kunye namanzi amdaka, ngoko ke kufuneka ikhuphe ezinye iziphene ezifana noxinzelelo lwe-in-situ kunye ne-deformation deformation;2. Inqanaba lokungangeni kule projekthi lichazwe njengeCandelo I, kwaye injongo ephambili yesicwangciso soyilo kukusombulula ingxaki yamanzi amdaka efektri kunye namanzi anetyuwa eninzi.Emva kokuba ukuvuza kwenzeka emva kokuba kufihliwe, ekugqibeleni kuya kuvuza, kubangela ukungcoliseka kwamanzi, okunempembelelo enkulu kwintlalontle, kwaye kubiza kakhulu ukufumana ukuvuza nokulungisa.Ngoko ke, xa ubeka iimbrane ezichasene ne-seepage, ulawulo lwekhwalithi kufuneka lufakwe kumsebenzi obalulekileyo.
Njengomthombo ongundoqo wokuqokelelwa kwamanzi emvula ukulungiselela unikezelo lwamandla oluphakathi kwiiprojekthi zamanzi okusela ezidolophini, iitanki zokugcina amanzi zidlala indima ebaluleke kakhulu.Ke ngoko, iiprojekthi ezininzi zetanki zogcino lwamanzi ezinexabiso lomzi mveliso wegeomembrane wexabiso elingangenwa manzi njengoko eyona ndlela yokuziphatha iyilwayo kwaye yakhiwe.Nangona ibakala lobunjineli kunye nelokwakha lisezantsi, lelakwaGrade 4 kunye namanye amabakala 4 ukuya 5 kwizakhiwo ezincinci neziphakathi, kodwa ngenxa yokuba lo vimba ufumaneka ezidolophini (elokishini) nakwiindawo zokuhlala ezilalini, ukuba ukuvuza kunye nokungalingani kwethambeka. okubangelwa, kunokubangela ukhuseleko olufana nokuwa Ingozi iya kubangelwa.
Iimpawu eziphambili zegeomembrane
1. Amandla aphezulu oxinzelelo kunye ne-ductility elungileyo;
2. Ukusebenza kakuhle umaleko wokungangeni manzi;
3. Ulwakhiwo olulula, olukhaphukhaphu, olulungele ukuthuthwa;
4. Iimpawu ezigqwesileyo zemichiza yendalo kunye ne-organic: I-membrane ye-HDPE engabonakaliyo ine-anti-aging, i-anti-ultraviolet, i-resilience efanelekileyo, i-puncture resistance, i-ductility ephantsi, i-deformation encinci ye-thermal, ukuthembeka okugqwesileyo kweekhemikhali ze-organic, ukuxhathisa okuphezulu kunye nokushisa okuphantsi, ukuchasana nokukhupha, i-oyile kunye ne-tar yamalahle, i-asidi, i-alkali, ityuwa, kunye nezinye izisombululo zemichiza;
5. Iindleko eziphantsi kunye neenzuzo eziphezulu zezoqoqosho ezibanzi;
6. Ukukhuselwa kokusingqongileyo: Izinto ezikhethiweyo ezikhethiweyo ze-polyethylene inwebu engenakunyakaziswa kwi-membrane ayityhefu emitsha ehambelana nokusingqongileyo.Umgaqo osisiseko we-membrane engenamanzi kukuba utshintsho kwimo jikelele aluyi kubangela naziphi na izinto ezinobungozi.Lolona khetho lulungileyo lokuzalanisa okuhambelana nokusingqongileyo.
