Chikamu chemubhedha chinofanirwa kuenzana uye shanduko ine hukobvu hunosvika masendimita makumi matatu uye dhayamita yepamusoro ye20 mm yecomposite geomembrane inofanira kuiswa.Saizvozvowo, chigadziko chesefa chinofanira kuiswa pa membrane, chichiteverwa nevhavha yekudzivirira.Iyo periphery ye membrane inofanirwa kubatanidzwa zvakasimba neiyo isingapindiki dhizaini yebhangi materu pamabhangi ese ari maviri.Kubatana pakati pemembrane isingapindiki uye girovha yeanchori inotemerwa zvichibva pane inotenderwa yekubata permeability gradient pakati pe membrane nekongiri.Polyvinyl chloride uye butyl erabha mafirimu anogona kunyatsonamirwa kune kongiri kumusoro uchishandisa zvinonamira kana solubilizer, saka kureba kwakamisikidzwa kunogona kupfupika zvakakodzera.Nekuda kwekusakwanisa kwemufirimu wepolyethylene kunamatira kune kongiri kumusoro, kureba kwekongiri yakamisikidzwa kunofanirwa kunge kuri 0.8m.
Geomembrane chinhu che geosynthetic chine mvura yakadzikira zvakanyanya.Kuti membrane iite basa rayo rakakodzera mukudzivirira kwesepage, kunze kwekuda kuti iyo membrane pachayo ive isingagoneki, kutarisisa kunofanirwa kubhadharwa kumhando yekuvaka yekuisa iyo impermeable membrane.
1. Kubatana pakati pe membrane isingapindiki uye muganhu wakapoteredza.Iyo membrane isingapindiki inofanira kunge yakanyatsobatanidzwa nemuganhu wakakomberedza.Panguva yekuvaka, anchor groove inogona kucherwa kuti ibatanidze hwaro uye kutsetseka kwebhangi.
Kana nheyo yacho iine jecha risina kudzika giravhu rinopindika, jecha rejecha rinofanira kucherwa kusvikira rapfuma mudombo, uye ipapo nheyo yekrete inofanira kudirwa kugadzirisa geomembrane mukongiri.Kana nheyo yacho ivhu risingapindiki, mugero weanchor wakadzika 2m uye hupamhi hunosvika 4m unogona kucherwa.Iyo geomembrane inoiswa mumugero, uye ipapo ivhu rinozara kumashure.Kana iyo nheyo iri yakadzika permeable layer yejecha nematombo, geomembrane inogona kushandiswa kuifukidza kudzivirira kubuda, uye kureba kwayo kunotarirwa zvichienderana nekuverenga.
Iyo yekubata kumeso pakati peiyo isingapindiki membrane uye iyo inotsigira zvinhu inofanirwa kuve yakatsetseka sezvinobvira kudzivirira membrane kuti isarasikirwa nemhedzisiro yayo isingapindike nekuroverwa pamateru.Zvikasadaro, yakanaka grained thermal layer inofanira kupihwa kudzivirira iyo firimu kubva mukukuvadzwa.
3. Kubatana kweiyo impermeable membrane pachayo.Nzira dzekubatanidza dzefirimu remvura isingapindiki rinogona kupfupikiswa mumhando nhatu, dzinoti, nzira yekubatanidza, nzira yewelding, uye nzira yevulcanization.Kusarudzwa kunoenderana neakasiyana mbichana emufirimu isingapindiki, uye kusapindirana kwemajoini ese ekubatanidza kunofanirwa kuongororwa.Composite geomembrane inofanirwa kushandiswa kudzivirira kuvuza nekuda kwekusagadzikana kwekubatana.
