1. Ukuba uthenga i-geomembrane edityanisiweyo yokuwelda ekhethekileyo, nceda wazise umenzi kwangaphambili ukuba inkqubo yokujika umphetho ifuneka ngokukhawuleza, oko kukuthi, xa i-geotextile kunye ne-geomembrane zibotshelelwe ngokushushu, imiphetho emibini iya kugcinwa emva kokuba iqengqiwe. Malunga ne-15-20 cm ngaphandle kokunamathela kwanele. Ukuba indawo yokuqhekeza umhlaba inkulu, inkqubo yokujika umphetho wentshona-end ifuneka ngokukhawuleza, kwaye inokuxazululwa kuphela nomenzi ngaphambi kokuba ufake iodolo.
2. Ngokufana neeprojekthi ezinkulu kakhulu, uvavanyo lokuntywiliselwa kwe-geomembrane edibeneyo lusebenzisa indlela yokutshiza eshushu, efana neHaoshengsheng. Nokuba umphetho wocango lokutshiza oshushu ugciniwe, umphezulu wangaphandle uyafudunyezwa kwaye uthengiswa ngumatshini wokutshiza oshushu, ukuze umphezulu omkhulu ubuyiselwe esithandweni, uze emva koko udityaniswe kwisitywina esiqinileyo ngokusebenzisa amandla okuthotywa.
3. I-Top paving: I-composite geomembrane ibekwe kwicala elinye, ishiya iindawo zomphetho wokuphosa kumacala omabini e-composite geomembrane. Xa kuthintelwa, ulwalathiso lomqulu ngamnye we-composite geomembrane kufuneka lulungiswe ukuze kube lula ukuwelda kakuhle kwe-rolls ezimbini ze-composite geomembrane kunye.
4. Emva kwe-composite geomembrane barricade, logama nje kukho imozulu embi, kuyimfuneko ukucinezela imiphetho ethile ngeengxowa zesanti ukuze zingavuthuzi kancinci, ukuze zihlangane ne-wide band engenakuphepheka, kwaye zibe bushelelezi kwaye zingabi namibimbi. Izixhobo ze-welded edge joint kufuneka zingabi namithombo yongcoliseko, ukufuma, uthuli, njl.njl. Ukukhanya okuhle kwi-welding, njengokucoca kwangoko, akuchaphazeli umgangatho we-welding ngendlela engabonakaliyo.
5. Xa ufunda nge-composite geomembrane welding, nceda ucele iingcali ezinamava ukuba zidibanise. Kukho umatshini we-hot melt welding. Kuxelwe ukuba ubukhulu be-composite geomembrane buxhomekeke kumatshini we-welding. Ubushushu kunye nenkqubela phambili kufuneka zilungiswe ngokuchanekileyo, kwaye ubukhulu be-composite geomembrane abukho emva kwe-0.1 mm. Ukuba incinci kakhulu, kulula ukuphuka xa idityanisiwe, kwaye umsebenzi we-composite geomembrane awuphumi ngenxa yomonakalo ngexesha lokusetyenziswa.
6. Ngokubanzi, iingcali zokuwelda ezinikwe ziinkampani zokubonelela nokuthengisa zonke zibandakanyeka ngokukodwa ekuwelding kwaye azikaze zihlolwe ngokongeza izixhobo. Nokuba sithenga izixhobo okanye sikhangela abavelisi abakhulu abaqhelekileyo, siza kongeza izixhobo ngoko nangoko. Umgangatho wemveliso yomshuwalense okokuqala.
