Umaleko ophezulu wengubo egqunyiweyo engenamanzi yifilimu ye-polyethylene (HDPE) enoxinaniso oluphezulu kwaye umaleko ongezantsi lilaphu elingalukwanga. Ingubo ye-sodium bentonite engenamanzi kunye nesiphumo esingcono sokungena kwamanzi igxininiswe phakathi kwe-geotextiles ephezulu yamandla usebenzisa indlela ekhethekileyo yokubethelwa kwenaliti kwaye emva koko ibekwe kwilaphu elingalukwanga. Uluhlu lwefilimu ye-polyethylene ephezulu (i-HDPE) inamathele kuyo. Ingubo ye-bentonite engangeni manzi inamandla angangeni manzi kunye ne-anti-seepage kuneengubo eziqhelekileyo ze-bentonite ezingenamanzi. Indlela yokukhusela amanzi kukuba i-bentonite particles yandisa xa ibonakaliswe emanzini, yenze inkqubo ye-colloid efanayo. Ngaphantsi kwesithintelo semigangatho emibini ye-geotextile, i-bentonite iyanda ukusuka kwi-disorder ukuya kwi-oda. Isiphumo sokunyuka kwamanzi ngokuqhubekayo kunye nokwandiswa kukwenza i-bentonite layer ngokwayo ibe nzima. , ngaloo ndlela ibe nefuthe lokuthintela amanzi.
Iimpawu ezibonakalayo zengubo egqunywe ngamanzi:
1. Ineempawu ezigqwesileyo zamanzi kunye ne-anti-seepage, uxinzelelo lwe-anti-seepage lwe-hydrostatic lunokufikelela ngaphezu kwe-1.0MPa, kunye ne-permeability coefficient yi-5 × 10-9cm / s. I-Bentonite yinto engokwemvelo engayi kuhlangabezana nokuguga kwaye inokuqina okulungileyo; kwaye ayisayi Nayiphi na impembelelo embi kokusingqongileyo yinto ehambelana nokusingqongileyo
2. Inazo zonke iimpawu zezixhobo ze-geotextile, ezifana nokuhlukana, ukuqiniswa, ukukhuselwa, ukuhluzwa, njl. Kulula ukwakha kwaye akuthinteli ukushisa kwendawo yokwakha. Isenokwakhiwa kwakhona ngaphantsi kwe-0℃. Ngethuba lokwakha, kufuneka ubeke kuphela ingubo ye-GCL engenamanzi phantsi. Xa usakha kwi-facade okanye ithambeka, yilungise ngezikhonkwane kunye neewasha, kwaye ugqithe njengoko kufuneka.
3. Kulula ukulungisa; nangemva kokuba ukwakhiwa kokuthintela amanzi (i-seepage) kugqityiwe, ukuba umgca wokukhusela amanzi wonakaliswe ngengozi, nje ngokuba inxalenye eyonakalisiweyo ilungiswa nje, ukusebenza okungahambi kakuhle kwamanzi kungabuyiselwa.
4. Umlinganiselo wexabiso lentsebenzo uphezulu kakhulu kwaye unoluhlu olubanzi lokusetyenziswa.
5. Ububanzi bemveliso bunokufikelela kwiimitha ezi-6, ezihambelana neenkcukacha ze-geotextile (imembrane) ngamazwe ngamazwe, ukuphucula kakhulu ukusebenza kakuhle kokwakhiwa.
6. Ilungele ukunyangwa kwe-anti-seepage kunye nokuvuza kwiindawo ezineemfuno eziphezulu zokungangeni kwamanzi kunye ne-anti-seepage, njengama-tunnels, i-subways, amagumbi angaphantsi, iipaseji ezingaphantsi komhlaba, izakhiwo ezahlukahlukeneyo eziphantsi komhlaba kunye neeprojekthi ze-waterscape ezinobuncwane bamanzi aphantsi komhlaba.
