Ukubekwa nokushiselwa kwama-geomembrane ezindaweni zokuhlangana kwemithambeka kuyizinto ezikhethekile. Ama-diaphragm angaphakathi kokungalingani, njengamakhona, kufanele asikwe abe “i-trapezoid eguquliwe” enobubanzi obuncane phezulu kanye nobubanzi obuncane phansi. Uzwane lomthambeka endaweni yokuhlangana phakathi komthambeka wesiteshi kanye nesisekelo sendawo ludinga nokuphathwa okukhethekile. Phakathi nenqubo yonke yokwakha, izingxenye ezilungisiwe ngemva kokuthatha amasampula kanye nezindawo lapho ukwakhiwa okujwayelekile kokushiselwa kungenakuvunyelwa khona, imithetho yokwakha kufanele yakhiwe ngokwesimo sangempela sendawo kanye nezimo zendawo, futhi ubuchwepheshe obukhethekile kufanele busetshenziswe ekwakheni.
Kunezimo eziningi enqubweni yokwakha i-geomembrane ezinganakwa kalula noma okunzima ukuzakha. Kulezi zimo, uma sizisingatha ngokungahleliwe noma singazinaki ngesikhathi sokwakha, kuzoletha izingozi ezithile ezifihliwe kulo lonke iphrojekthi yokulwa nokuvuza kwamanzi. Ngakho-ke, abakhiqizi be-geomembrane basikhumbuza ngobunzima bokwakha be-geomembrane ezingxenyeni ezikhethekile zesayithi.
1. Ukubekwa nokushiselwa kwama-geomembrane ezindaweni zokuhlangana kwemithambeka kuyizinto ezikhethekile. Ama-diaphragm angaphakathi kokungalingani, njengamakhona, kufanele asikwe abe “i-trapezoid eguquliwe” enobubanzi obuncane phezulu kanye nobubanzi obuncane phansi. Umsebenzisi kufanele abale ngokunembile isilinganiso sobubanzi nokuphakama ngokuya ngesimo sangempela sendawo kanye nosayizi othize wemithambeka. Uma isilinganiso singabanjwanga kahle, ubuso befilimu ku-bevel “buzoqhuma” noma “bulenga”.
2. Uzwane lomthambeka endaweni ehlangana nomthambeka wesiteshi kanye nesisekelo sendawo ludinga ukwelashwa okukhethekile. Amaphuzu okwakha kulokhu alandelayo: ulwelwesi olusemthambekeni lubekwa eceleni komthambeka ebangeni elingu-1.5 ukusuka ozwaneni lomthambeka m, bese luhlanganiswa nelwelwesi phansi kwensimu.
3. Phakathi nenqubo yonke yokwakha, izingxenye ezilungisiwe ngemva kokuthatha amasampula kanye nezindawo lapho ukwakhiwa okuvamile kokushisela kungeke kwamukelwe khona, imithetho yokwakha kufanele yakhiwe ngokwesimo sangempela sendawo kanye nezimo zendawo, futhi kufanele kusetshenziswe ubuchwepheshe obukhethekile ekwakheni. Isibonelo, "T Type" kanye "double T" Ukushisela kwesibili kwe-"type" weld kungokwe-special position welding.
