1. Ingabe likhona ithonya elivela ekudlulisweni kwefilimu?Ngemuva kokuthi ifilimu ibekwe, umugqa wokungena ngaphambi kokuba ifilimu ikhuphuke kancane, kuyilapho umugqa wokungena ngemuva kwefilimu uyancipha kakhulu.Ngesikhathi esifanayo, isihloko samanzi esihlala njalo ngaphansi kwefilimu siba sikhulu, futhi ikhanda lamanzi ngemuva kwefilimu lehla kakhulu.Ukusatshalaliswa kwama-hydraulic gradients nakho kushintshe kakhulu.Ngaphambi kokubeka ifilimu, kunendawo ezacile ephezulu ye-hydraulic gradient endaweni lapho kuhlangana khona inhlabathi eyisihlabathi esisantekenteke kanye nongqimba lobumba, kodwa ngemva kokubeka ifilimu, i-hydraulic gradient ku-dike iba mncane, kuyilapho i-hydraulic gradient ingaphansi kwe-dike. ifilimu ikhula ngokuphawulekayo, ebonisa ukuthi ukugeleza kwamanzi kushintshile ngenxa yokuba khona kwefilimu Endleleni yokugeleza, i-seepage igxilwe kusukela phansi kwe-membrane, okungukuthi, i-membrane ye-anti-seepage inomphumela obalulekile we-anti-seepage.Ngaphandle kwendawo encane ezansi kwentengo yefekthri ye-geomembrane eyenziwe ngendlela ebhaliwe, ama-hydraulic gradients kwezinye izindawo angaphakathi kobubanzi obuvunyelwe be-hydraulic gradient, futhi iphansi lolwelwesi likusendlalelo esingezansi sayo yonke iphrojekthi, enobubanzi obuncane. futhi akukho monakalo we-osmotic ozokwenzeka.
2. Ithonya lokuqina kwefilimu.Lapho iphansi le-membrane liku-0.5m kude nongqimba lobumba, uma kuqhathaniswa nongqimba lobumba olufakwe ngaphansi kwe-membrane, umugqa wokumanzisa ngemva kokwanda kwe-membrane, ikhanda lamanzi likhuphuka kakhulu, futhi isihloko samanzi siphansi. i-membrane iba yingcosana, okubonisa umphumela wokunqanda ukuvuleka kolwelwesi oluma mpo lwe-anti-seepage Yehliswe kakhulu.Kungabonakala ukuthi uma ungqimba lwemvelo oluphikisana nokubona okwemvelo olufana nongqimba lobumba lukhona endaweni, noma ngabe ungqimba lobumba lufakwe ngaphansi kwe-membrane lunethonya elikhulu kumphumela wokulwa nokubona kwe-membrane.Lapho ungqimba lobumba lufakwa ngaphansi kwe-membrane, kwakhiwa umgoqo ovaliwe ongenamanzi.Uma kuqhathaniswa nalapho ungqimba lobumba lungafakwanga phansi kwe-membrane, umphumela we-anti-seepage uthuthukiswa kakhulu.Lapho ungqimba lobumba lungafakwa ngaphansi kolwelwesi, kuba nongqimba oluncane olukwazi ukungena phakathi kolwelwesi olungamanzi kanye nolwelwesi lobumba.Lapho amanzi egeleza eya endaweni ezungezile, kwakheka umgudu wokugeleza oqinile.Lapho iphansi le-membrane likude nongqimba lobumba, ukushuba kongqimba oluvuvukalayo kuyanda, umphumela wokungena uyanda, futhi umphumela wokulwa ne-seepage we-anti-seepage membrane uba buthaka.
Lapho iphansi le-membrane elingangeneki lingabekwa ongqimbeni lobumba, i-hydraulic gradient iyanda endaweni eseduze naphansi kwe-wholesale textured geomembrane, kodwa yehla ongqimbeni lobumba.Uma kuqhathaniswa necala lokungabikho kwe-membrane, i-hydraulic gradient yongqimba lobumba phansi kwe-membrane iyanda, futhi i-hydraulic gradient yongqimba lobumba ngemuva kolwelwesi iyancipha, okubonisa ukuthi ukugeleza kwamanzi kugxilwe phambi kolwelwesi, futhi ngenxa yokuguqulwa kwendlela yokugeleza kwamanzi, amanzi amaningi ageleza ngemuva kolwelwesi.Ukuya phezulu kunciphisa ukugcwala kokugeleza emngceleni wongqimba lomhlabathi, okusasiza ekuzinzeni kokugeleza kwamanzi onqenqemeni.Ukwengeza, i-hydraulic gradient yesendlalelo ngasinye (ngaphandle kwengxenye encane engaphansi kwe-membrane) isencane kune-gradient ye-hydraulic evumelekile, ngakho-ke lapho ulwelwesi olungaphansi lungambozwa ungqimba lobumba, ukuhluleka kokungena ngokuvamile kuzokwenziwa. kungenzeki, kodwa umphumela wokunqanda ukuvuleka kolwelwesi olume mpo kuzoba ukuncishiswa okusobala.
3. Umphumela wokuqhekeka kwe-membrane.Lapho ulwelwesi lucekelwa phansi, imigudu emisha yokuphuma kwamanzi izokwakhiwa, okubangela ukusatshalaliswa kabusha kwenkambu ye-sepage.Umugqa wokungena ngemuva kwe-membrane wanda kakhulu, futhi ikhanda lamanzi nalo landa kakhulu, ikakhulukazi endaweni eyonakele.Umthelela wokunqanda ukuvuleka kolwelwesi olume mpo lwe-anti-seepage ngokusobala uncishisiwe.I-hydraulic gradient ngaphambi nangemva kwe-membrane ekhiqizwa abakhiqizi be-geomembrane be-LDPE iphukile ngokusobala iyanda, kuyilapho i-hydraulic gradient kwezinye izindawo iyancipha, okubonisa ukuthi ukugeleza kwamanzi nge-membrane kuphukile, kodwa ukwanda kwe-gradient okubangelwa ukugxila kwe-osmotic kuye kwanda. ithonya elincane.Uma i-dike ihlinzeka ngesiteshi eside sokuphuma kwamanzi, ngeke kuthinte ukuzinza kwe-dike.Ngaphezu kwalokho, i-hydraulic gradient yezinye izendlalelo iyancishiswa, encane kune-gradient evumelekile ye-hydraulic, ngakho-ke lapho ulwelwesi lubhujiswa, ukuhluleka kwe-osmotic ngeke kwenzeke.
