Kuma-geotextile endawo enkulu, umshini wokushisela onemithungo emibili usetshenziswa kakhulu ekushiseleni, kanti ezinye izingxenye kumele zilungiswe futhi ziqiniswe ngomshini wokushisela we-extrusion. I-geomembrane iyafaneleka uma ibekwe ngokuqinile ngokwezidingo ezisezinhlwini zomthambeka kanye nezindiza.
Hlola ukuthi ubuso obungaphansi bejoyinti bubushelelezi futhi buqinile. Uma kunezidumbu zangaphandle, kufanele zilahlwe kahle kusenesikhathi. Hlola ukuthi ububanzi bokugoqana kwe-weld bufanelekile yini, nokuthi i-geomembrane ejoyintini kufanele ibe yithafa futhi iqine ngokulinganayo. Sebenzisa isibhamu somoya oshisayo ukuze ukale isisindo se-geomembrane ezimbili. Izingxenye ze-Stack zihlanganiswe ndawonye. Ibanga eliphakathi kwamaphuzu okuxhuma akufanele lidlule u-80 mm. Lawula izinga lokushisa lomoya oshisayo ngaphandle kokubhubhisa i-geomembrane.
I-geomembrane ayinaso isiqondiso esivundlile ekushiseni imithambeka. Ingabhekwa kanjani njengefanelekile? Ukubekwa kwe-geomembrane endaweni yokuthambeka kanye ne-plane joint kulandela ngokuqinile izidingo, okungukuthi, ifanelekile. I-geomembrane yesistimu engezansi yokulwa nokuvuza ibekwe ngengubo engangeni manzi ye-bentonite, kanti uhlelo lwe-geomembrane oluvala ukuvuza lubekwe ngqo enhlabathini yezinsalela zemfucuza yezimboni. Ngaphambi kokubeka i-geomembrane, isisekelo kufanele sihlolwe ngokuphelele, futhi isisekelo kufanele sibe siqinile futhi siyisicaba, sibe nokujula okuqondile okungu-25mm ngaphandle kwezimpande. Inhlabathi engokwemvelo, itshe, amabhlogo ekhonkrithi kanye nemigoqo yensimbi kungathinta izingcezu zokwakha ze-geomembrane.
Ukuguquguquka kokuqina okubangelwa ukushintsha kwezinga lokushisa kufanele kucatshangelwe lapho kubekwa i-geomembrane. Ngenxa yamandla aphansi e-coating ku-weld, ububanzi be-joint ehlanganayo phakathi kwe-coating kanye ne-coating akufanele bube ngaphansi kuka-15 cm. Ngaphansi kwezimo ezijwayelekile, isiqondiso se-joint layout kufanele sihlelwe eceleni kwe-slope.
Okungenhla kuyimiyalelo ethile mayelana ne-geomembrane ngokuhambisana ngokuqinile nezidingo zamajoyinti okuthambeka kanye nendiza.
