Kwi-geotextiles ezinkulu, umatshini wokuwelda onemithungo emibini usetyenziselwa kakhulu ukuwelda, kwaye ezinye iindawo kufuneka zilungiswe kwaye ziqiniswe ngumatshini wokuwelda we-extrusion. I-geomembrane iyafaneleka ukuba ibekwe ngokungqongqo ngokweemfuno ezikwi-slope kunye ne-plane joints.
Qinisekisa ukuba umphezulu ongezantsi welungu uthambile kwaye uqinile. Ukuba kukho imizimba yangaphandle, kufuneka ilahlwe ngokufanelekileyo kwangaphambili. Jonga ukuba ububanzi bokugquma kwe-weld bufanelekile na, kwaye i-geomembrane ekwilungu kufuneka ibe tyaba kwaye iqine ngokulinganayo. Sebenzisa isibhamu somoya oshushu ukulinganisa ubunzima be-geomembranes ezimbini. Iinxalenye ze-Stack zidibene kunye. Umgama phakathi kwamanqaku oqhagamshelo akufuneki udlule kwi-80 mm. Lawula ubushushu bomoya oshushu ngaphandle kokutshabalalisa i-geomembrane.
I-geomembrane ngokusisiseko ayinalo icala elithe tye ekudibaniseni i-slope. Ingathathwa njani njengefanelekileyo? Ukubekwa kwe-geomembrane kwindawo yokutyibilika kunye ne-plane joint kulandela ngokungqongqo iimfuno, oko kukuthi, ifanelekile. I-geomembrane yenkqubo esezantsi yokulwa nokuvuza ibekwe ngengubo engangeni manzi ye-bentonite, kwaye inkqubo yokugquma i-geomembrane yokulwa nokuvuza ibekwe ngqo kumhlaba wenkunkuma yemizi-mveliso. Ngaphambi kokubeka i-geomembrane, i-basement kufuneka ihlolwe ngokupheleleyo, kwaye isiseko kufuneka sibe siqinile kwaye sithe tyaba, sinobunzulu obuthe nkqo obuyi-25mm ngaphandle kweengcambu. Umhlaba wendalo, amatye, iibhloko zekhonkrithi kunye neentsimbi zentsimbi zinokuchaphazela iziqwenga zokwakha ze-geomembrane.
Ukuguquguquka kokuxinana okubangelwa kukutshintsha kobushushu kufuneka kuqwalaselwe xa kubekwa i-geomembrane. Ngenxa yamandla aphantsi okugqunywa kwi-weld, ububanzi bejoyinti edibeneyo phakathi kwengubo kunye nengubo akufuneki bube ngaphantsi kwe-15 cm. Kwiimeko eziqhelekileyo, ulwalathiso lolwakhiwo lwejoyinti kufuneka lucwangciswe ecaleni kwendlela yokuthambeka.
Oku kungasentla yimiyalelo ethile malunga ne-geomembrane ngokuhambelana ngokungqongqo neemfuno zeendawo zokuthambeka kunye neendawo zokuma.
