Xa kuthelekiswa nezinto zemveli ezingenamanzi, i-polyethylene geomembrane ephezulu yoxinaniso inomsebenzi ongcono wokuchasana nokubona kunye nobomi benkonzo obude. Iimpawu zayo ziqhele ukuba ziimitha ezi-6 ububanzi kunye ne-0.2 ukuya kwi-2.0 ye-millimeters ngobukhulu. Ngokweendawo ezahlukeneyo zokusetyenziswa, umbala we-polyethylene geotextile yoxinaniso oluphezulu unokwahlulwa ube mnyama namhlophe.

2, Ukusetyenziswa kwe-polyethylene ephezulu yoxinanisoigeombrane

1. Ubunjineli bogcino lwamanzi: I-polyethylene geomembrane yoxinaniso oluphezulu isetyenziswa kakhulu kubunjineli bolondolozo lwamanzi, njengamadama, imida, ulawulo lwemilambo, njl.njl. kubunjineli be-hydraulic, i-high-density polyethylene geomembrane isetyenziswa ikakhulu kwi-anti-seepage kunye neyodwa, engakwazi ukuthintela ngokufanelekileyo ukungena kwamanzi kunye nokukhukuliseka, kunye nokuphucula ukhuseleko kunye nokuzinza kobunjineli be-hydraulic.

2. Ubunjineli bokusingqongileyo: Kubunjineli bokusingqongileyo, i-polyethylene geomembrane ephezulu yoxinaniso isetyenziselwa ukuchasana nokubona kunye nokwahlula kwiindawo ezifana neendawo zokulahla inkunkuma kunye nezityalo zokucocwa kwamanzi amdaka. Ngenxa ye-anti-seepage egqwesileyo kunye nokuxhathisa ukubola, i-polyethylene geomembrane ephezulu yoxinaniso inokuthintela ngokufanelekileyo ukungcola kunye nokuvuza kwenkunkuma, ukukhusela amanzi aphantsi komhlaba kunye nokusingqongileyo komhlaba.

3. Ubunjineli bokwakha: Kubunjineli bokwakha, i-polyethylene geomembrane ene-high-density isetyenziselwa ikakhulu ukuthintela amanzi kunye nokwahlula kwiindawo ezingaphantsi, kwiitonela, kwi-subways nakwezinye iindawo. Xa kuthelekiswa nezinto zemveli ezingenamanzi, i-polyethylene geomembrane ephezulu yoxinaniso inomsebenzi ongcono we-anti-seepage kunye nobomi obude benkonzo, enokuphucula ukhuseleko kunye nokuzinza kwezakhiwo.

3、 Izinto eziluncedo ze-polyethylene geomembrane ephezulu yoxinaniso

1. Ukusebenza kakuhle kwe-anti-seepage: I-polyethylene geomembrane yoxinaniso oluphezulu lunomsebenzi obalaseleyo wokuchasana nokubona, onokuthi uthintele ngokufanelekileyo ukungena kwamanzi kunye nokukhukuliseka, kunye nokuphucula ukhuseleko kunye nokuzinza kweeprojekthi zokulondoloza amanzi.

2. Ukuxhathisa okuqinileyo kwe-corrosion: I-polyethylene ye-geomembrane yoxinaniso oluphezulu inokumelana nokugqwala okuqinileyo kwaye inokumelana nokukhukuliseka kweekhemikhali ezahlukeneyo, ukukhusela ngokufanelekileyo ukungcola kunye nokuvuza kwenkunkuma.

3. Ubomi benkonzo ende: Ubomi benkonzo ye-high-density polyethylene geomembrane ngokuqhelekileyo ingaphezu kweminyaka engama-20, enokunciphisa ngokufanelekileyo iindleko zokugcina ubunjineli.

4. Ukwakhiwa okulula: Ukwakhiwa kwe-polyethylene ephezuluigeombraneilula, kwaye inokudityaniswa nge-welding okanye i-bonding. Isantya sokwakha sikhawuleza, esinokunciphisa ngokufanelekileyo ixesha leprojekthi.

5. Ukhuseleko lokusingqongileyo: Uxinaniso oluphezulu lwe-polyethylene geomembrane alunatyhefu kwaye alunavumba, aluvelisi izinto eziyingozi, alunabungozi kwindalo, kwaye luyahlangabezana neemfuno zokusingqongileyo. Okwangoku, ngenxa yokusebenza kakuhle kwe-anti-seepage, inokuthintela ngokufanelekileyo ukuvuza kwezinto ezinobungozi kwaye iqinisekise ukhuseleko lobomi babantu kunye nepropati.
4. Isiphelo
Isishwankathelo, i-high-density polyethylene geomembrane, njengohlobo olutsha lwezinto eziphathekayo ze-geotechnical, ineenzuzo ezifana nokusebenza okugqwesileyo kwe-anti-seepage, ukuxhatshazwa kwe-corrosion, ubomi benkonzo ende, ukwakhiwa okulula, ukukhuselwa kwendalo kunye nokhuseleko. Ke ngoko, isetyenziswa kakhulu kwimimandla efana nokugcinwa kwamanzi, ukukhuselwa kwendalo, kunye nobunjineli bokwakha. Ngophuhliso oluqhubekayo lwetheknoloji, uluhlu lwentsebenzo kunye nosetyenziso lwe-polyethylene geomembrane ephezulu yoxinaniso luya kwandiswa ngakumbi kwaye luphuculwe, lubonelele ngeenkonzo ezingcono zokuveliswa kwabantu kunye nobomi.
