Ukusetshenziswa kweGeomembranes
Emkhakheni wezindawo zokulahla imfucuza ezinobungani nemvelo: Ulwelwesi oluhlanganisiwe lwe-geotextile lungasetshenziswa kumaphrojekthi afana namachweba avuzayo kanye namanzi emvula kanye nokuphambukiswa kwendle okumboza ulwelwesi lwezindawo zokulahla imfucumfucu.
Impahla ye-geomembrane ephikisana ne-seepage yokulahlwa kukadoti: i-HDPE # geomembrane # ephezulu, impahla ye-polymer, amandla aphezulu, impilo ende yesevisi, nokunwetshwa okuphezulu.
Ukucaciswa kwe-high-density polyethylene geomembrane: Ububanzi buvamise ukuba ngu-6m, futhi ukujiya kungenziwa ngendlela oyifisayo phakathi kuka-0.1mm no-3.0mm.
Udinga ukwazi inhloso ye-geomembrane edingekayo kuqala.Izinhlobo ezahlukene ze-geomembrane zinezakhiwo nezici ezihlukene, ezifana nokungangeni kwamanzi, ukuphefumula, ukumelana nokubanda, ukuguga, njll. Kuphela ngemva kokuba injongo inqunyiwe ungakhetha umkhiqizo ofanele.
I-Geomembranes ihlukaniswa ngamaleveli ekhwalithi alandelayo ngokusekelwe ezintweni ezihlukahlukene ezisetshenziswayo:
I-membrane evamile ephikisana ne-seepage, ulwelwesi oludala lwe-anti-seepage olujwayelekile kazwelonke (GB/T 17643-1998);
Ulwelwesi olusha olujwayelekile lukazwelonke lokulwa nokubona (i-GB/T17643-2011) i-GH-1 ne-GH-2S zihambisana nemvelo, kanti ulwelwesi olwakhiwe emadolobheni olumelene nokubona ikhasi (CJ/T 234-2006) lunezinkomba zobuchwepheshe ezifanayo nezinga le-American. GM-13;
Ukuminyana okuphezulu kwe-polyethylene geomembrane, njengento ebalulekile emelene ne-seepage ye-geosynthetic, ibalulekile ekuvikelweni kwemvelo kanye nokuzihlukanisa okunqanda ukuvuleka.Kulawa maphrojekthi aphikisana nemvelo, avimbela amanzi angcolile kanye nemfucumfucu ukuba ingene emanzini angaphansi komhlaba futhi iwangcolise.Ingase futhi isetshenziselwe ukubeka izendlalelo ezingenamanzi ukuvimbela ukungena kwamanzi.
Izinyathelo zokufaka i-geomembrane:
Ukulungiselela ukuxhunywa kwe-polyethylene geomembrane ye-high-density geomembrane yendawo yokulahla i-landfill: Ngaphambi kokuqala ukufakwa kwe-geomembrane, kuyadingeka ukuhlanza indawo yokwakhiwa ukuze kuqinisekiswe indawo ebushelelezi ngaphandle kwama-protrusions noma izinto ezibukhali ukugwema ukulimaza i-geomembrane.
Izinyathelo zokubeka ulwelwesi lwe-geotextile: Beka ulwelwesi lwe-geotextile endaweni yokwakha, ngemiphetho eyeqenayo engaba ngu-15cm, bese ulungiselela ukuxhuma ngomshini wokushisela oncibilika oshisayo.
