Ububanzi bokubeka i-geomembrane eyinhlanganisela
Ukusebenza kwempilo yokusebenza kwe-geomembrane eyinhlanganisela kunqunywa ngokuyinhloko ukuthi ingabe ifilimu yepulasitiki ingaphansi kokwelashwa okuxosha amanzi.Ngokwezindinganiso zikazwelonke zeSoviet Union, ifilimu ye-polyethylene enobukhulu obungu-0.2m kanye ne-stabilizer yobunjiniyela be-hydraulic ingasebenza iminyaka engu-40 kuya kwengu-50 ngaphansi kwezimo zamanzi ahlanzekile kanye neminyaka engama-30 kuya kwengu-40 ngaphansi kwezimo zendle.Idamu laseZhoutou Reservoir ekuqaleni laliyidamu eliwudonga oluwumgogodla, kodwa ngenxa yokuwa kwedamu, ingxenye engaphezulu yodonga oluwumgogodla yasuswa.Ukuze uphathe ukusebenza kwe-anti-seepage ephezulu, udonga oluthambekele oluphikisana nekhasi lwengezwe esisekelweni.Ngokuvumelana nokuboniswa kokuphepha kanye nokubola kweDamu leZhoutou Reservoir, ukuze kubhekwane nokuvuza kwendawo ebuthakathaka kanye nokuvuza kwesisekelo sedamu okubangelwa ukudilika kwenhlabathi okuphindaphindiwe kwedamu, izakhiwo ezingenakunyakaziswa njenge-bedrock curtain grouting, i-grouting surface yempi, ukushaywa kwamanzi kanye ikhethini elibamba kahle eligcwalisa ingemuva, kanye nodonga lwepuleti lepuleti lejethi elinengcindezi ephezulu selwamukelwe ngokuya ngokuvimbela ukugeleza kwamanzi okuqondile.
Izici ze-geomembrane eyinhlanganisela: I-geomembrane eyinhlanganisela iyimpahla ye-geomembrane eyakhiwe ngefilimu yepulasitiki njenge-anti-seepage substrate nendwangu engalukiwe.Umsebenzi wayo wokunqanda ukuvuleka uncike ekusebenzeni kwe-anti-seepage yefilimu yepulasitiki.Indlela yayo yokuqina iwukuthi ukungagxili kwefilimu yepulasitiki kuvimbela ukuvuza kwedamu lomhlaba emanzini, ukumelana nomfutho wamanzi nokujwayela ukuguquguquka kwedamu ngenxa yamandla alo amakhulu okudonsa kanye nezinga lokulibaziseka;Indwangu engalukiwe iphinde ibe yikhemikhali yemicu ye-polymer emifushane, eyakhiwe ngokubhoboza inaliti noma i-thermal bonding, futhi inamandla aphezulu nokubambezeleka.Ngemuva kokuthintwa namafilimu epulasitiki, akukhulisi nje kuphela amandla aqinile nokumelana nokubhoboza kwamafilimu epulasitiki, kodwa futhi kwandisa i-coefficient yokungqubuzana kwendawo yempi ngenxa yemininingwane eqinile yezindwangu ezingalukiwe, okuzuzisa ukuzinza kwama-geomembranes ayinhlanganisela. kanye nezingqimba zokucasha.
Ngakho-ke, impilo yokusebenza ye-geomembrane eyinhlanganisela yanele ukwanelisa impilo yokusebenza eceliwe ukuze kuvinjelwe ukugeleza kwedamu.
Udonga oluphezulu lumbozwe nge-geomembrane eyinhlanganisela yokuvimbela ukugeleza kwamanzi, ingxenye engezansi ilandela udonga lokuvimbela ukugeleza kwamanzi kanye nengxenye engaphezulu ifinyelela ukuphakama okungama-358.0m (0.97m ngaphezu kwezinga lesheke lezikhukhula).
Ukumelana nokushisa okuphezulu, ukusebenza okuhle kwe-antifreeze.
Njengamanje, amafilimu epulasitiki asetshenziselwa ukulawulwa kwe-seepage ekhaya nakwamanye amazwe ahlanganisa i-polyvinyl chloride (PVC) ne-polyethylene (PE), okuyizinto eziguquguqukayo zamakhemikhali e-polymer ezinesisindo esincane, ukubambezeleka okuqinile, nokuguquguquka okuphezulu kokuguquguquka.
Ngesikhathi esifanayo, banokumelana kahle namagciwane kanye nokuzwela kwamakhemikhali, futhi abesabi i-asidi, i-alkali, nokugqwala kukasawoti.
