Kuchuluka kwa kuyala kophatikizana kwa geomembrane

Moyo wogwira ntchito wa gulu la geomembrane umatsimikiziridwa makamaka ngati filimu yapulasitiki imayikidwa pamankhwala othamangitsa madzi.Malinga ndi mfundo za dziko la Soviet Union, filimu ya polyethylene yokhala ndi makulidwe a 0.2m ndi stabilizer ya hydraulic engineering imatha kugwira ntchito kwa zaka 40 mpaka 50 pansi pamadzi oyera komanso zaka 30 mpaka 40 pansi pa zimbudzi.Damu la Zhoutou Reservoir poyambirira linali dambo la khoma, koma chifukwa cha kugwa kwa damu, gawo lapamwamba la khoma lapakati linachotsedwa.Pofuna kuthana ndi ntchito yapamwamba yotsutsa-seepage, khoma lotsutsana ndi seepage linawonjezeredwa kumunsi.Mogwirizana ndi chiwonetsero chachitetezo ndikuwola kwa Damu la Zhoutou Reservoir, kuti athe kuthana ndi kutayikira kofooka komanso kutayikira kwa maziko a damu komwe kumachitika chifukwa cha kugumuka kwamadzi komwe kumachitika mobwerezabwereza, zomangira zathupi zomwe sizingafanane ndi gwero lamakatani, kugwetsa matope, kuwotcha, kuwotcha ndi kuwola. chinsalu chogwira bwino chakumbuyo, komanso khoma lopanda mphamvu la jet grouting lavomerezedwa potsata kupewa kutsika kwapang'onopang'ono.
Mawonekedwe a geomembrane yophatikizika: Geomembrane yophatikizika ndi zinthu za geomembrane zopangidwa ndi filimu yapulasitiki ngati gawo lapansi lotsutsana ndi masamba ndi nsalu zopanda nsalu.Ntchito yake yotsutsa-seepage imadalira ntchito yotsutsa-seepage ya filimu yapulasitiki.Kachitidwe kake kazovuta ndikuti kusasunthika kwa filimu ya pulasitiki kumapangitsa kuti madzi azitha kutuluka m'madzi, kulimbana ndi kuthamanga kwa madzi ndikusintha kusintha kwa madamu chifukwa cha mphamvu zake zazikulu komanso kuchedwa;Nsalu yosalukidwanso ndi mankhwala a ulusi waufupi wa polima, womwe umapangidwa kudzera pa kukhomerera kwa singano kapena kulumikizana ndi matenthedwe, ndipo imakhala ndi mphamvu zolimba komanso kuchedwa.Pambuyo kulumikizidwa ndi mafilimu apulasitiki, sikuti kumangowonjezera mphamvu zolimba komanso kukana kwamphamvu kwamafilimu apulasitiki, komanso kumawonjezera mikangano yankhondo pamwamba pankhondo chifukwa cha tsatanetsatane wa nsalu zosalukidwa, zomwe zimapindulitsa kukhazikika kwa ma geomembranes ophatikizika. ndi zigawo zobisika.
Choncho, moyo wa opareshoni wa gulu la geomembrane ndi wokwanira kukhutiritsa moyo wa opareshoni womwe wapemphedwa kuti apewe kuphulika kwa madamu.
Khoma lopendekera kumtunda limakutidwa ndi geomembrane yophatikizika kuti itetezeke, ndipo gawo lapansi likutsatira khoma lotchinga lopingasa ndi kumtunda komwe kumafika pamtunda wa 358.0m (0.97m kumtunda kuposa kuchuluka kwa kusefukira kwa cheki).
Kukana kutentha kwakukulu, ntchito yabwino ya antifreeze.
Pakalipano, mafilimu apulasitiki omwe amagwiritsidwa ntchito poyang'anira madzi kunyumba ndi kunja akuphatikizapo polyvinyl chloride (PVC) ndi polyethylene (PE), zomwe ndi zipangizo zosinthika za polima zokhala ndi kulemera kochepa, kuchedwa kwamphamvu, ndi kusinthasintha kwakukulu kwa mapindikidwe.
Panthawi imodzimodziyo, ali ndi kukana kwabwino kwa mabakiteriya ndi mphamvu zamagetsi, ndipo samawopa asidi, alkali, ndi mchere.
