Umaleko ophezulu we-membrane-igqunywe ngengubo engangeni manzi yifilimu ye-polyethylene (HDPE) ephezulu yoxinaniso, kwaye umaleko ongezantsi yilaphu elingalukwanga. Uluhlu lwefilimu ye-polyethylene ephezulu (i-HDPE) ifakwe kuyo. Ingubo ye-bentonite engangeni manzi inamandla angangeni manzi kunye nesakhono sokuchasana ne-anti-seepage kunengubo eqhelekileyo ye-bentonite engenamanzi. Indlela yokungena kwamanzi kukuba i-bentonite particles ihluma ngamanzi ukwenza inkqubo ye-colloidal efanayo. Ngaphantsi kwesithintelo semigangatho emibini ye-geotextiles, i-bentonite iyanda ukusuka kwi-disorder ukuya kwi-oda. Isiphumo sokunyuka kwamanzi ngokuqhubekayo kunye nokwandiswa kukwenza i-bentonite layer ngokwayo ibe nzima. , ukuze ube nempembelelo yokungangeni manzi.
Iimpawu ezibonakalayo zebhanyabhanya-egqunywe ngengubo engenamanzi:
1. Inomsebenzi ogqwesileyo wokungangeni manzi kunye nokuchasana nokubona, uxinzelelo lwe-anti-seepage lwe-hydrostatic lunokufikelela ngaphezu kwe-1.0MPa, kunye ne-coefficient yokulinganisa i-5 × 10-9cm / s. I-Bentonite yinto engokwemvelo yendalo, engayi kuhlangabezana nokuguga kwaye inokuqina okulungileyo; Nayiphi na impembelelo embi kwimo engqongileyo yinto ehambelana nokusingqongileyo
2. Inazo zonke iimpawu zezixhobo ze-geotextile, ezifana nokuhlukana, ukuqiniswa, ukukhuselwa, ukuhluzwa, njl njl. Ukwakhiwa kulula kwaye akukhawulelwanga ngukushisa kwendawo yokwakha, kwaye inokwakhiwa ngaphantsi kwe-0 ° C. Ngexesha lokwakha, beka nje ingubo ye-GCL engenamanzi phantsi, uyilungise ngezikhonkwane kunye neewasha xa ukwakhiwa kwi-facade okanye i-slope, kwaye uyifake njengoko kufuneka.
3. Kulula ukulungisa; kwanasemva kokuba ukwakhiwa kokungena manzi (seepage) kugqityiwe, ukuba umaleko wokungangeni manzi wonakaliswe ngengozi, ngokude nje ukuba inxalenye eyonakalisiweyo ilungiswa nje, ukusebenza kokungangeni kwamanzi kunokuphinda kubuyiselwe njengoko kwakunjalo.
4. Umlinganiselo wokusebenza-ixabiso uphezulu, kwaye ukusetyenziswa kubanzi kakhulu.
5. Ububanzi bemveliso bunokufikelela kwiimitha ezi-6, ezihambelana neenkcukacha ze-geotextile yamazwe ngamazwe (i-membrane), ephucula kakhulu ukusebenza kakuhle kokwakhiwa.
6. Ilungele ukunyangwa kwe-anti-seepage kunye ne-anti-seepage kwiinkalo zeemfuno eziphezulu zokungena kwamanzi kunye ne-anti-seepage, ezifana: iitonela, i-subways, amagumbi angaphantsi, iipaseji eziphantsi komhlaba, izakhiwo ezahlukahlukeneyo eziphantsi komhlaba kunye neeprojekthi ze-waterscape ezinobuncwane bamanzi aphantsi komhlaba.
