I-geomembrane ebushelelezi
Incazelo emfushane:
I-geomembrane ebushelelezi ivame ukwakhiwa nge-polymer material eyodwa, njenge-polyethylene (PE), i-polyvinyl chloride (PVC), njll. Ingaphezulu layo libushelelezi futhi liyisicaba, ngaphandle kokuthungwa okusobala noma izinhlayiya.
Isakhiwo esiyisisekelo
I-geomembrane ebushelelezi ivame ukwakhiwa nge-polymer material eyodwa, njenge-polyethylene (PE), i-polyvinyl chloride (PVC), njll. Ingaphezulu layo libushelelezi futhi liyisicaba, ngaphandle kokuthungwa okusobala noma izinhlayiya.
- Izici
- Ukusebenza okuhle kokunqanda ukuphuma: Inokungena okuphansi kakhulu futhi ingavimbela ngempumelelo ukungena koketshezi. Inomphumela omuhle wokuvinjelwa emanzini, uwoyela, izisombululo zamakhemikhali, njll. I-coefficient ye-anti-seepage ingafinyelela ku-1×10⁻¹²cm/s ukuya ku-1×10⁻¹⁷cm/s, engahlangabezana nezidingo zokunqanda ukuphuma kwamaphrojekthi amaningi. .
- Ukuzinza kwamakhemikhali okuqinile: Inokumelana okuhle kakhulu kwe-asidi ne-alkali nokumelana nokugqwala. Ingahlala izinzile ezindaweni ezihlukene zamakhemikhali futhi ayiguguleka kalula ngamakhemikhali asenhlabathini. Ingakwazi ukumelana nokugqwala kokugxila okuthile kwe-asidi, i-alkali, usawoti kanye nezinye izixazululo.
- Ukumelana kahle nezinga lokushisa eliphansi: Kusengakwazi ukugcina ukuguquguquka okuhle kanye nezakhiwo zemishini endaweni enezinga lokushisa eliphansi. Isibonelo, amanye ama-geomembranes abushelelezi ekhwalithi ephezulu ye-polyethylene asenokunwebeka okuthile kokuthi -60℃ kuya -70℃ futhi akulula ukuphuka ukuphuka.
- Ukwakhiwa okulungile: Ingaphezulu libushelelezi futhi i-coefficient ye-friction incane, elungele ukubekwa ezindaweni ezihlukahlukene nezisekelo. Ingaxhunywa nge-welding, i-bonding nezinye izindlela. Isivinini sokwakha siyashesha futhi ikhwalithi kulula ukuyilawula.
Inqubo Yokukhiqiza
- Indlela yokubumba i-Extrusion blow: I-polymer eluhlaza ishiselwa esimweni sokuncibilika futhi ikhishwe nge-extruder ukuze yenze okungenalutho kwe-tubular. Ngemva kwalokho, umoya ocindezelweyo uvuthela eshubhuni elingenalutho ukuze likhule futhi libambelele esibunjeni ukuze liphole futhi lilolonge. Ekugcineni, i-geomembrane ebushelelezi itholakala ngokusika. I-geomembrane ekhiqizwa yile ndlela inokuqina okufanayo kanye nezakhiwo ezinhle zemishini.
- Indlela yekhalenda: I-polymer eluhlaza iyashiswa bese ikhishwa futhi yelulwe ngamarola amaningi ekhalenda ukuze kwakhe ifilimu enogqinsi nobubanzi obuthile. Ngemuva kokupholisa, i-geomembrane ebushelelezi iyatholakala. Le nqubo inekhono eliphezulu lokukhiqiza kanye nobubanzi bomkhiqizo obanzi, kodwa ukufana kogqinsi kubi kakhulu.
Izinkambu Zokusebenza
- Iphrojekthi yokonga amanzi: Isetshenziselwa ukwelapha okunqanda ukuvuleka kwezindawo zokonga amanzi njengamadamu, amadamu, nemisele. Ingavimbela ngempumelelo ukuvuza kwamanzi, ithuthukise ukugcinwa kwamanzi kanye nokuhanjiswa kahle kwamaphrojekthi okonga amanzi, futhi yandise impilo yesevisi yephrojekthi.
- I-Landfick: Njengomugqa ovimbela ukugeleza phansi phansi nangaseceleni kwendawo yokulahla indle, ivimbela i-leachate ekungcoliseni umhlabathi namanzi angaphansi futhi ivikela imvelo ezungezile.
- Ukwakha okungangeni manzi: Kusetshenziswa njengesendlalelo esingangeni manzi ophahleni, ngaphansi, endlini yokugezela nezinye izingxenye zesakhiwo ukuvimbela ukungena kwamanzi emvula, amanzi angaphansi komhlaba kanye nokunye umswakama esakhiweni futhi kuthuthukiswe ukusebenza okungangeni kwamanzi kwesakhiwo.
- I-Artificial landscape: Isetshenziselwa ukuvimbela ukubonwa kwamachibi okwenziwa, amachibi okwakheka kwezwe, izindawo ze-waterscape zenkundla yegalofu, njll., ukugcina ukuzinza komzimba wamanzi, ukunciphisa ukuvuza kokulahlekelwa kwamanzi, nokuhlinzeka ngesisekelo esihle sokudala indawo.
Imininingwane kanye Nezinkomba Zobuchwepheshe
- Imininingwane: Ugqinsi lwe-geomembrane ebushelelezi luvamise ukuba phakathi kuka-0.2mm no-3.0mm, futhi ububanzi ngokuvamile buphakathi kuka-1m no-8m, obungenziwa ngokwezifiso ngokuya ngezidingo zamaphrojekthi ahlukene.
- Izinkomba zobuchwepheshe: Kufaka phakathi amandla aqinile, ubude ngesikhathi sekhefu, amandla okudabula i-engeli yesokudla, ukumelana nengcindezi ye-hydrostatic, njll. Amandla aqinile ngokuvamile aphakathi kuka-5MPa no-30MPa, ubude ngesikhathi sekhefu buphakathi kuka-300% no-1000%, ukukhala kwe-engeli engakwesokudla. amandla aphakathi kuka-50N/mm no-300N/mm, futhi ukumelana nengcindezi ye-hydrostatic kuphakathi kuka-0.5MPa kanye 3.0MPa.
