1. Kodi pali chikoka chilichonse kuchokera kumayendedwe amakanema?Pambuyo pa kuikidwa kwa filimuyo, mzere wolowetsamo filimuyo isanatuluke pang'ono, pamene mzere wolowera pambuyo filimuyo imachepa kwambiri.Panthawi imodzimodziyo, mutu wamadzi wokhazikika pansi pa filimuyo umakhala wandiweyani, ndipo mutu wamadzi kumbuyo kwa filimuyo umatsika kwambiri.Kugawidwa kwa ma hydraulic gradients kwasinthanso kwambiri.Musanayike filimuyo, pali malo ocheperako amtundu wa hydraulic gradient pamtunda wa dothi la mchenga ndi dongo, koma mutayala filimuyo, hydraulic gradient mu dike imakhala yaying'ono, pamene hydraulic gradient pansi pa denga. filimuyo imakula kwambiri, kusonyeza kuti madzi akuyenda asintha chifukwa cha kukhalapo kwa filimuyo Mu njira yothamanga, seepage imayikidwa kuchokera pansi pa nembanemba, ndiko kuti, anti-seepage nembanemba imakhala ndi mphamvu yotsutsa-seepage.Kupatula malo ang'onoang'ono pansi pa mtengo wa fakitale ya geomembrane, ma hydraulic gradients m'madera ena onse ali mkati mwa hydraulic gradient range, ndipo pansi pa nembanemba ndi m'munsi mwa pulojekiti yonseyo, ndi kagawo kakang'ono. ndipo palibe kuwonongeka kwa osmotic komwe kudzachitika.
2. Chikoka cha filimu makulidwe.Pamene pansi pa nembanemba ndi 0.5m kutali ndi dongo wosanjikiza, poyerekeza ndi dongo wosanjikiza anaikapo pansi pa nembanemba, kunyowa mzere pambuyo nembanemba ukuwonjezeka, mutu wa madzi ukuwonjezeka kwambiri, ndi mutu mutu wa madzi pansi. nembanemba imakhala yochepa, kusonyeza kutsutsa-seepage zotsatira za vertical anti-seepage membrane Yachepetsedwa kwambiri.Zitha kuwoneka kuti pamene chiwombankhanga chachilengedwe chotsutsana ndi seepage monga dongo chimakhalapo kwanuko, ngati dongo ladongo likulowetsedwa pansi pa nembanemba limakhala ndi mphamvu yaikulu pa anti-seepage effect ya nembanemba.Dongo likalowetsedwa pansi pa nembanemba, chotchinga chotsekeka chosasunthika chimapangidwa.Poyerekeza ndi pamene dongo la dongo silinalowetsedwe pansi pa nembanemba, zotsatira za anti-seepage zimakhala bwino kwambiri.Dongo likapanda kulowetsedwa pansi pa nembanembayo, pamakhala kagawo kakang'ono kamene kangapitirire pakati pa nembanemba yosasunthika ndi dongo.Madzi akamapita kumalo ozungulira, njira yothira madzi yamphamvu kwambiri imapangidwa.Pamene pansi pa nembanemba ndi kutali ndi dongo la dongo, makulidwe a permeable wosanjikiza amawonjezeka, mphamvu yolowera imawonjezeka, ndipo zotsatira zotsutsana ndi zowonongeka za anti-seepage membrane zimafooketsa.
Pamene pansi pa nembanemba impermeable si anaika mu dongo wosanjikiza, ndi hayidiroliki gradient ukuwonjezeka m'dera pafupi pansi pa yogulitsa textured geomembrane, koma amachepetsa mu dongo wosanjikiza.Poyerekeza ndi vuto lopanda nembanemba, hydraulic gradient ya dongo pansi pa nembanemba imawonjezeka, ndipo hydraulic gradient ya dongo kuseri kwa nembanemba imachepa, kusonyeza kuti madzi oyenda akhazikika kutsogolo kwa nembanemba, ndipo chifukwa cha kusintha kwa njira yoyendetsera madzi, madzi ambiri amayenda kumbuyo kwa nembanemba.Kukwera mmwamba kumachepetsa kuchuluka kwa seepage pamalire a dothi wosanjikiza, komwe kumathandizirabe kukhazikika kwa madziwo mumpanda.Kuphatikiza apo, ma hydraulic gradient a gawo lililonse (kupatula gawo laling'ono pansi pa nembanemba) akadali ang'onoang'ono kuposa hydraulic gradient yovomerezeka, kotero ngati pansi pa nembanemba sikukuphimbidwa ndi dongo, kulephera kulowa mkati kumakhala kotheka. sizichitika, koma zotsatira zotsutsana ndi mawonekedwe a nembanemba yoyimirira zidzakhala Kuchepetsa koonekeratu.
3. Zotsatira za kuphulika kwa membrane.Nembanembayo ikawonongeka, njira zatsopano zamasamba zidzapangidwa, zomwe zimapangitsa kugawanikanso kwa gawo la seepage.Mzere wolowera kumbuyo kwa nembanemba unakula kwambiri, ndipo mutu wamadzi unakulanso kwambiri, makamaka pamalo owonongeka.Zotsatira za anti-seepage za nembanemba yotsutsa-yoyimirira mwachiwonekere yachepetsedwa.Ma hydraulic gradient asanayambe ndi pambuyo pa nembanemba opangidwa ndi opanga LDPE geomembrane akusweka mwachiwonekere akuwonjezeka, pamene hydraulic gradient m'madera ena amachepetsa, kusonyeza kuti madzi oyenda kudzera mu nembanemba amasweka, koma kuwonjezeka kwa gradient chifukwa cha ndende ya osmotic kukopa pang'ono.Pamene dike limapereka njira yayitali yolowera, sizikhudza kukhazikika kwa dike.Kuphatikiza apo, hydraulic gradient ya zigawo zina imachepetsedwa, yomwe ndi yaying'ono kuposa hydraulic gradient yovomerezeka, kotero kuti nembanemba ikawonongeka, kulephera kwa osmotic sikudzachitika.
