1. Haba hari ingaruka zituruka kuri firime?Iyo firime imaze gushyirwaho, umurongo winjira mbere yuko firime izamuka gato, mugihe umurongo winjira nyuma ya firime ugabanuka cyane.Muri icyo gihe, umutwe wamazi uhoraho hepfo ya firime uba mwinshi, kandi umutwe wamazi inyuma ya firime ugabanuka cyane.Ikwirakwizwa rya hydraulic gradients naryo ryahindutse cyane.Mbere yo gushyira firime, hari agace ka hydraulic gahoro gahoro gahoro gahuza ubutaka bwumucanga nubutaka bwibumba, ariko nyuma yo gushira firime, hydraulic gradient muri dike iba nto, mugihe hydraulic gradient hepfo hepfo. firime yiyongera cyane, byerekana ko amazi yatembye bitewe nuko hariho firime Mu nzira itemba, seepage iba yibanda munsi ya membrane, ni ukuvuga ko anti-seepage membrane igira ingaruka zikomeye zo kurwanya seepage.Usibye agace gato kari munsi yikiguzi cyuruganda rwa geomembrane, hydraulic gradients mubindi bice byose biri murwego rwemewe rwa hydraulic, kandi hepfo ya membrane iri murwego rwo hasi rwumushinga wose, hamwe nurwego ruto. kandi nta kwangirika kwa osmotic kuzabaho.
2. Ingaruka yubunini bwa firime.Iyo epfo ya membrane iri 0.5m uvuye kurwego rwibumba, ugereranije nigice cyibumba cyinjijwe munsi yigitereko, umurongo wogosha nyuma yibice byiyongera, umutwe wamazi wiyongera cyane, hamwe numutwe wamazi hepfo ya ururenda ruba ruke, byerekana ingaruka zo kurwanya seepage ya vertical anti-seepage membrane yagabanutse cyane.Birashobora kugaragara ko mugihe urwego rusanzwe rwo kurwanya seepage nkigice cyibumba kibaho mugace, niba ibumba ryinjijwe munsi yibibabi bigira uruhare runini mukurwanya anti-seepage ya membrane.Iyo igumba ryibumba ryinjijwe munsi yigitereko, habaho inzitizi ifunze.Ugereranije nigihe ibumba ritinjijwe munsi ya membrane, ingaruka zo kurwanya seepage ziratera imbere cyane.Iyo ibumba ryibumba ritinjijwe munsi yigitereko, habaho igicucu cyoroshye hagati yicyuma kidashobora kwangirika nicyumba cyibumba.Iyo amazi atemba akikikije, hashyizweho umuyoboro ukomeye ugereranije.Iyo epfo ya membrane iri kure yibumba ryibumba, ubunini bwurwego rwinjira bwiyongera, ingaruka zo kwinjira, kandi ingaruka zo kurwanya seepage zirwanya intege nke.
Iyo epfo ya membrane idashobora gushyirwa mubumba ryibumba, hydraulic gradient yiyongera mugace kegereye hepfo ya geomembrane, ariko ikagabanuka mubumba.Ugereranije nikibazo cyo kutagira membrane, hydraulic gradient yibumba ryibumba munsi ya membrane iriyongera, kandi hydraulic gradient yibumba ryibumba inyuma ya membrane iragabanuka, byerekana ko amazi atemba yibanze imbere ya membrane, kandi kubera ihinduka ryinzira yamazi, amazi menshi atemba inyuma ya membrane.Kugenda hejuru bigabanya ubukana bwamazi kumupaka wubutaka bwubutaka, buracyafasha mugutuza kwamazi kumugezi.Mubyongeyeho, hydraulic gradient ya buri cyiciro (usibye igice gito kiri munsi ya membrane) iracyari ntoya kurenza hydraulic gradient yemerewe, ubwo rero iyo hepfo ya membrane idapfundikijwe nibumba, kunanirwa kwinjira muri rusange ntibibaho, ariko anti-seepage ingaruka ya vertical membrane izaba igaragara Kugabanuka.
3. Ingaruka zo guturika kwa membrane.Iyo membrane isenyutse, hazashyirwaho imiyoboro mishya ya seepage, itera isaranganya ryumurima.Umurongo winjira inyuma ya membrane wariyongereye cyane, kandi umutwe wamazi nawo wiyongereye cyane, cyane cyane mubice byangiritse.Ingaruka zo kurwanya-seepage ya vertical anti-seepage membrane biragaragara ko yagabanutse.Hydraulic gradient mbere na nyuma ya membrane yakozwe na LDPE inganda za geomembrane zavunitse biragaragara ko byiyongera, mugihe hydraulic gradient mubindi bice bigabanuka, byerekana ko amazi atembera muri membrane yavunitse, ariko kwiyongera kwa gradient biterwa no kwibanda kwa osmotic. imbaraga nke.Iyo dike itanga umuyoboro muremure, ntabwo bizahindura ituze rya dike.Byongeye kandi, hydraulic gradient yizindi nzego iragabanuka, ikaba ntoya kuruta hydraulic gradient yemewe, bityo mugihe membrane yangiritse, kunanirwa kwa osmotic ntikuzabaho.
