High-density polyethylene geomembrane isetshenziswa kakhulu ezindaweni zokulahla udoti, emachibini anokwakheka kwezwe, kanye namachibi.Izinga eliphansi lasemaphandleni libekwe phansi, futhi umklamo jikelele wophahla lwe-membrane unobukhulu bengqimba yokuzivikela, ngakho-ke ingozi yokuvuza ayiphezulu.Nokho, ukugandaywa kwezindonga zesakhiwo sikakhonkolo kuwukwakhiwa kwephrojekthi yokuqala, futhi kunezinkinga ezimbili ezinkulu ekwakhiweni: obunye wukugandaya ulwelwesi olungangeneli odongeni lwendlu yokugcina impahla engu-4m ukuphakama.I-membrane engangenisi ithwala ngokushesha umthelela wamandla namanzi angcolile, ngakho-ke kufanele Isuse okunye ukushiyeka okufana ne-in-situ stress kanye ne-bearing deformation;2. Izinga lokungangenisi lale phrojekthi lishiwo njenge-Class I, futhi inhloso enkulu yohlelo lokuklama ukuxazulula inkinga yamanzi angcolile asefekthri kanye namanzi amaningi anosawoti.Uma kuvuza ngemva kokufihlakala, ekugcineni kuzovuza, kubangele ukungcoliswa kwamanzi, okunomthelela omkhulu emphakathini, futhi kubiza imali eningi ukuthola ukuvuza nokukulungisa.Ngakho-ke, lapho ubeka ulwelwesi lwama-anti-seepage, ukuphathwa kwekhwalithi kufanele kufakwe emsebenzini obalulekile.
Njengomthombo obalulekile wokuqoqwa kwamanzi emvula wokuphakelwa kukagesi endaweni eyodwa kumaphrojekthi wamanzi okuphuza asemadolobheni, amathange okugcina amanzi adlala indima ebaluleke kakhulu.Ngakho-ke, amaphrojekthi amaningi ethangi lokugcina amanzi anesendlalelo sentengo yefekthri ye-texture ye-geomembrane engangeni manzi njengoba ukuziphatha okuyinhloko kuklanywa futhi kwakhiwe.Nakuba izinga lobunjiniyela kanye nebanga lokwakha liphansi, lingelebanga lesi-4 namanye amabanga 4 kuya ku-5 amabhilidi amancane naphakathi nendawo, kodwa ngenxa yokuthi ichibi lisemadolobheni (emalokishini) nasezindaweni zokuhlala zasemakhaya, uma ukuvuza nokungalingani kwemithambeka okubangelwa, kungase kubangele ngisho nokuphepha njengokuwa Ingozi izobangelwa.
Izici ezibalulekile ze-geomembrane
1. Amandla aphezulu okucindezela kanye ne-ductility enhle;
2. Ukusebenza okuhle kongqimba olungangeni manzi;
3. Ukwakhiwa okulula, okungasindi, futhi okulula ukuthuthwa;
4. Izakhiwo ezinhle kakhulu zamakhemikhali aphathekayo kanye nemvelo: I-HDPE i-membrane engenakunyakaziswa inokulwa nokuguga, i-anti-ultraviolet, ukuqina okuhle, ukumelana nokubhoboza, i-ductility ephansi, ukuguqulwa okuncane kokushisa, ukuthembeka okuhle kakhulu kwamakhemikhali e-organic, ukumelana nokushisa okuphezulu nokuphansi, Ukumelana nokuvuza, uwoyela netiyela yamalahle, i-asidi, i-alkali, usawoti, nezinye izixazululo zamakhemikhali;
5. Izindleko eziphansi kanye nezinzuzo eziphezulu zezomnotho eziphelele;
6. Ukuvikelwa kwemvelo: Izinto ezingavuthiwe ezikhethelwe ulwelwesi olunamandla lwe-polyethylene olungagxumeki izinto ezintsha ezingenabuthi ezihambisana nemvelo.Isimiso esiyisisekelo solwelwesi olungangeni manzi ukuthi izinguquko esimweni esivamile ngeke zibangele noma yiziphi izinto eziyingozi.Kuyisinqumo esingcono kakhulu sokuzalanisa okuhambisana nemvelo.
