Ukusika kunye nokuthutha: Ngokusekelwe kwiirekhodi zomlinganiselo wendawo yokubeka, bhala inani le-bundle enkulu ye-geomembrane cut kwaye uyithuthe kwindawo yokubeka ngokwenani. Ingqalelo, musa ukutsala okanye ukutsala ngenkani i-geomembrane ngexesha lokuhamba ukunqanda izinto ezibukhali ekuyigqobhozeni.
Ukwakhiwa kunye nofakelo lwe-geomembrane laying:
I-1) Kufuneka idlule ukusuka ezantsi ukuya kwindawo ephezulu, ngaphandle kokutsala ngokuqinileyo, ishiya umda we-1.50% yokucwila kwendawo kunye nokwelula. Ukuqwalasela eyona meko yale projekthi, ithambeka liya kubekwa ngokulandelelana ukusuka phezulu ukuya ezantsi.
2) Amalungu obude obude bezakhelo ezikufutshane akumele abe kumgca othe tye othe tye kwaye kufuneka agxadazwe ngaphezu kwe-1M ukusuka komnye nomnye.
3) Ijoyinti yelongitudinal kufuneka ibe yi-1.50m ubuncinane ukusuka kunyawo lwedama kunye nonyawo olugobileyo, kwaye kufuneka lubekwe kwindawo ethe tyaba.
4) Qala ngasemva ngasemva kwithambeka kuqala.
5) Xa ubeka i-slope, ulwalathiso lwefilimu kufuneka luhambelane ngokusisiseko nomgca we-slope.
Ukubekwa kwe-Slope: Ngaphambi kokubeka i-geomembrane ye-anti-seepage kwi-slope, indawo yokubeka kufuneka ihlolwe kwaye ilinganiswe. Ngokusekelwe kubungakanani obulinganisiweyo, i-membrane echasene ne-seepage ehambelana nobukhulu kwindawo yokugcina impahla kufuneka ihanjiswe kwiqonga lokuqala lokumisa i-anchoring. Ngexesha lokubeka, indlela efanelekileyo "yokutyhala kunye nokubeka" ukusuka phezulu ukuya phezulu kufuneka yamkelwe ngokwemiqathango yangempela kwisayithi. Kwindawo emise okwefeni, kufuneka isikwe ngokufanelekileyo ukuqinisekisa ukuba zombini iziphelo eziphezulu kunye nezisezantsi ziqiniswe ngokuqinileyo.
Ukubekwa kwezantsi: Ngaphambi kokubeka i-geomembrane ye-anti-seepage, indawo yokubeka kufuneka ihlolwe kwaye ilinganiswe. Ngokusekelwe kubungakanani obulinganisiweyo, i-membrane echasene ne-seepage ehambelana nobukhulu kwindawo yokugcina impahla kufuneka ihanjiswe kwindawo ehambelana nayo. Xa ubeka, utyhalwa ngesandla kwicala elithile. Ukulungelelaniswa kunye nokulungelelaniswa: Ukubekwa kwe-HDPE geomembrane, nokuba kumathambeka okanye kumzantsi wesiza, kufuneka kube lula kwaye ngokuthe tye, kugweme imibimbi kunye ne-ripples, ukwenzela ukulungelelanisa kunye nokulungelelanisa ii-geomembranes ezimbini. Ububanzi be-overlap ngokubanzi buyi-10cm kumacala omabini ngokweemfuno zoyilo.
Ukucinezela ifilimu: Sebenzisa iingxowa zesanti ukucinezela kwangexesha i-HDPE geomembrane elungelelanisiweyo ukuthintela umoya kunye nokutsala.
Ukubeka kwindawo yokubeka i-anchoring: Umlinganiselo othile we-membrane ye-anti-seepage kufuneka ugcinwe phezulu kwi-anchoring ye-anchoring ngokweemfuno zoyilo ukulungiselela ukucwiliswa kwendawo kunye nokwelula.
Umdibaniso weLongitudinal: Indawo enyukayo ingaphezulu, icandelo lokuhla lisezantsi, kwaye kukho ubude obaneleyo bokudityaniswa=15cm. Emva kokwamkelwa kwe-bentonite pad yokubeka, indawo ibekwe ngesandla kwindlela ethile.
