Izindaba

Ngenxa yokusebenza kwayo okuhle kakhulu kwe-anti-seepage namandla emishini aphezulu kakhulu, i-polyethylene (PE) isetshenziswa kabanzi emikhakheni eminingi. Emkhakheni wezinto zokwakha, i-high-density polyethylene (HDPE) geomembrane, njengohlobo olusha lwezinto ezibonakalayo ze-geotechnical, isetshenziswa kakhulu kwezobunjiniyela njengokugcina amanzi, ukuvikelwa kwemvelo, kanye nezindawo zokulahla imfucumfucu. Lesi sihloko sizonikeza isingeniso esinemininingwane, ukusetshenziswa, kanye nezinzuzo ze-high-density polyethylene geomembrane.

1, Isingeniso se-polyethylene geomembrane ephezulu kakhulu

High density polyethylene geomembrane uhlobo lwempahla ye-geosynthetic eyenziwe ikakhulukazi nge-high-density polyethylene (HDPE), enamandla amakhulu emishini kanye nokumelana nokugqwala. Uma kuqhathaniswa nezinto zendabuko ezingangeni manzi, i-polyethylene geomembrane enokuminyana okuphezulu inokusebenza okungcono kakhulu kokunqanda ukuphuma kwamanzi kanye nempilo ende yesevisi. Ukucaciswa kwayo ngokuvamile kungamamitha angu-6 ububanzi namamilimitha angu-0.2 kuya ku-2.0 ukujiya. Ngokwezindawo ezahlukahlukene zokusetshenziswa, umbala we-high-density polyethylene geotextile ungahlukaniswa ube omnyama nomhlophe.
2. Ukusetshenziswa kwe-high-density polyethylene geomembrane

1. Ubunjiniyela bokongiwa kwamanzi: I-polyethylene geomembrane ene-high density high isetshenziswa kakhulu kubunjiniyela bokonga amanzi, njengamadamu, ama-embankings, ukulawulwa kwemifula, njll. Ebunjiniyela be-hydraulic, i-high-density polyethylene geomembrane isetshenziselwa ikakhulukazi i-anti-seepage kanye nokuhlukaniswa, okungase kuvimbela ngempumelelo ukungena nokuguguleka kwamanzi, futhi kuthuthukise ukuphepha nokuzinza kobunjiniyela bamanzi.

2. Ubunjiniyela bezemvelo: Ebunjiniyela bezemvelo, i-polyethylene geomembrane ene-high-density isetshenziselwa kakhulu ukulwa nokugeleza nokuhlukaniswa ezindaweni ezifana nezindawo zokulahla imfucumfucu kanye nezindawo zokuhlanza indle. Ngenxa yokumelana kwayo nokubola nokugqwala okuhle kakhulu, i-polyethylene geomembrane enezinga eliphezulu inganqanda ngempumelelo ukuvuza kwendle nodoti, ivikele amanzi angaphansi komhlaba kanye nemvelo yomhlabathi.

3. Ubunjiniyela bokwakha: Ebunjiniyela bezokwakha, i-polyethylene geomembrane ene-high-density polyethylene geomembrane isetshenziselwa ikakhulukazi ukuvimbela amanzi kanye nokuhlukaniswa kwabantu ezindaweni ezingaphansi, imigudu, imigwaqo engaphansi komhlaba, nakwezinye izindawo. Uma kuqhathaniswa nezinto zendabuko ezingangeni manzi, i-polyethylene geomembrane enobukhulu obuphezulu inokusebenza okungcono kakhulu kwe-anti-seepage nempilo ende yesevisi, engathuthukisa ukuphepha nokuzinza kwezakhiwo.

3. Izinzuzo ze-high-density polyethylene geomembrane

1. Ukusebenza okuhle kokunqanda ukubola: I-polyethylene geomembrane ye-high density high inokusebenza okuhle kakhulu kwe-anti-seepage, okungavimbela ngokuphumelelayo ukungena nokuguguleka kwamanzi, futhi kuthuthukise ukuphepha nokuzinza kwamaphrojekthi okonga amanzi.

2. Ukumelana nokugqwala okuqinile: I-polyethylene geomembrane ye-high density high inokumelana nokugqwala okuqinile futhi ingamelana nokuguguleka kwamakhemikhali ahlukahlukene, ukuvimbela ngokuphumelelayo ukuthuthwa kwendle nokuvuza kukadoti.

3. Impilo ende yesevisi: Impilo yesevisi ye-high-density polyethylene geomembrane ngokuvamile ingaphezu kweminyaka engama-20, enganciphisa ngempumelelo izindleko zokulungisa ubunjiniyela.

4. Ukwakhiwa okulula: Ukwakhiwa kwe-high-density polyethylene geomembrane kulula, futhi ingaxhunywa nge-welding noma i-bonding. Isivinini sokwakha siyashesha, esingafinyeza ngokuphumelelayo ubude bephrojekthi.

5. Ukuphepha kwemvelo: I-polyethylene geomembrane ene-high density polyethylene ayinabuthi futhi ayinaphunga, ayikhiqizi izinto eziyingozi, ayinangozi emvelweni, futhi ihlangabezana nezimfuneko zemvelo. Khonamanjalo, ngenxa yokusebenza kwayo okuhle kwe-anti-seepage, ingavimbela ngempumelelo ukuvuza kwezinto eziyingozi futhi iqinisekise ukuphepha kwezimpilo zabantu kanye nempahla.
4. Isiphetho
Kafushane, i-polyethylene geomembrane enezinga eliphezulu, njengohlobo olusha lwezinto ezibonakalayo ze-geotechnical, inezinzuzo ezifana nokusebenza okuhle kakhulu kwe-anti-seepage, ukumelana nokugqwala, impilo ende yesevisi, ukwakhiwa okulula, ukuvikelwa kwemvelo nokuphepha. Ngakho-ke, isetshenziswa kakhulu emikhakheni efana nokongiwa kwamanzi, ukuvikelwa kwemvelo, nobunjiniyela bokwakha. Ngokuthuthuka okuqhubekayo kobuchwepheshe, uhla lokusebenza kanye nokusetshenziswa kwe-polyethylene geomembrane ephezulu kakhulu kuzokwandiswa futhi kuthuthukiswe, kuhlinzekwe ngezinsizakalo ezingcono zokukhiqizwa komuntu nokuphila.
