Indawo yokulala kufuneka ilinganiswe kwaye umaleko oguqukayo onobunzima obumalunga ne-30 cm kunye ne-particle enkulu ye-20 mm ye-geomembrane edibeneyo kufuneka ibekwe.Ngokufanayo, uluhlu lokucoca kufuneka lubekwe kwi-membrane, lulandelwe nguluhlu olukhuselayo.I-periphery ye-membrane kufuneka idibaniswe ngokuqinileyo kunye nomgangatho ongenakunqandwa wemithambeka yebhanki kuzo zombini iibhanki.Ukudibanisa phakathi kwe-membrane engavumelekanga kunye ne-anchor groove inqunywe ngokusekelwe kwi-gradient yoqhagamshelwano oluvumelekileyo phakathi kwe-membrane kunye nekhonkrithi.Iifilimu ze-polyvinyl chloride kunye ne-butyl yerabha inokubambelela kakuhle kumphezulu wekhonkrithi usebenzisa i-adhesives okanye i-solubilizers, ngoko ubude obufakwe ngaphakathi bunokuba bufutshane ngokufanelekileyo.Ngenxa yokungakwazi kwefilimu ye-polyethylene ukunamathela kumgangatho wekhonkrithi, ubude bekhonkrithi edibeneyo buya kuba ubuncinane be-0.8m.
I-Geomembrane yimathiriyeli ye-geosynthetic enokungena kwamanzi aphantsi kakhulu.Ukuze i-membrane idlale indima yayo ekukhuselweni kwamanzi, ngaphezu kokufuna ukuba i-membrane ngokwayo ingabonakali, ingqalelo kufuneka ihlawulwe kumgangatho wokwakha wokubeka i-membrane engabonakaliyo.
1. Ukudibanisa phakathi kwe-membrane engabonakaliyo kunye nomda ojikelezayo.I-membrane engabonakaliyo kufuneka idibaniswe ngokuqinileyo kunye nomda ojikelezayo.Ngethuba lokwakha, i-anchor groove inokugrunjwa ukuze idibanise isiseko kunye ne-slope yebhanki.
Ukuba isiseko yintlabathi enganzulwanga yentlabathi engenekayo, igrabile yesanti kufuneka igrunjwe de ibe sisityebi etyeni, kwaye ke isiseko sekhonkrithi kufuneka sigalelwe ukulungisa i-geomembrane kwikhonkrithi.Ukuba isiseko singumaleko wodongwe olungagungqiyo, umsele we-ankile onobunzulu obuyi-2m kunye nobubanzi obumalunga ne-4m unokombiwa.I-geomembrane ibekwe emseleni, kwaye emva koko udongwe luzaliswe ngasemva.Ukuba isiseko singumaleko onzulu wesanti kunye negrabile, i-geomembrane ingasetyenziselwa ukugubungela ukuthintela ukungcola, kwaye ubude bayo bunqunywe ngokusekelwe ekubaleni.
Ubuso bokudibanisa phakathi kwe-membrane engabonakaliyo kunye nezinto ezixhasayo kufuneka zibe lula ngokusemandleni ukukhusela i-membrane ukuba ilahlekelwe yimpembelelo yayo engabonakaliyo ngokuhlatywa kwi-slope.Ngaphandle koko, i-fine grained layer thermal kufuneka inikezelwe ukukhusela ifilimu kumonakalo.
3. Ukudibanisa kwe-membrane engabonakaliyo ngokwayo.Iindlela zokudibanisa ifilimu emanzi engabonakaliyo ingashwankathelwa kwiindidi ezintathu, ezizezi, indlela yokudibanisa, indlela ye-welding, kunye nendlela ye-vulcanization.Ukukhethwa kuxhomekeke kwizinto ezihlukeneyo zefilimu engabonakaliyo, kunye nokunyanzeliswa kwazo zonke iindawo zokudibanisa kufuneka zihlolwe.I-geomembrane ehlanganisiweyo kufuneka isetyenziswe ukunqanda ukuvuza ngenxa yoxhulumaniso olungekho mgangathweni.
