1. Puas muaj kev cuam tshuam los ntawm kev xa cov yeeb yaj kiab?Tom qab zaj duab xis tso, cov kab infiltration ua ntej zaj duab xis nce me ntsis, thaum cov kab infiltration tom qab zaj duab xis txo qis heev.Nyob rau tib lub sijhawm, cov dej tsis tu ncua hauv qab ntawm zaj duab xis ua ntom ntom, thiab lub taub hau dej tom qab zaj duab xis poob qis.Kev faib tawm ntawm hydraulic gradients kuj tau hloov pauv loj.Ua ntej tso zaj duab xis, muaj qhov sib luag siab hydraulic gradient cheeb tsam ntawm kev sib tshuam ntawm cov xuab zeb loam av thiab cov av nplaum txheej, tab sis tom qab tso zaj duab xis, hydraulic gradient nyob rau hauv lub dike ua me, thaum lub hydraulic gradient nyob rau hauv qab ntawm lub zaj duab xis nce siab, qhia tau hais tias cov dej ntws tau hloov pauv vim qhov muaj nyob ntawm zaj duab xis Nyob rau hauv txoj kev ntws, seepage yog concentrated los ntawm lub hauv qab ntawm daim nyias nyias, uas yog, lub anti-seepage membrane muaj ib tug tseem ceeb anti-seepage nyhuv.Tsuas yog ib cheeb tsam me me nyob rau hauv qab ntawm cov textured geomembrane Hoobkas nqi, cov hydraulic gradients nyob rau hauv lwm qhov chaw yog tag nrho nyob rau hauv lub tso cai hydraulic gradient ntau yam, thiab hauv qab ntawm daim nyias nyias yog nyob rau hauv lub qis txheej ntawm tag nrho cov project, nrog ib tug me me ntau yam. thiab tsis muaj kev puas tsuaj osmotic yuav tshwm sim.
2. Kev cuam tshuam ntawm zaj duab xis thickness.Thaum lub hauv qab ntawm daim nyias nyias yog 0.5m deb ntawm cov av nplaum txheej, piv nrog cov av nplaum txheej tso rau hauv qab ntawm daim nyias nyias, cov kab ntub dej tom qab daim nyias nyias tau nce, lub taub hau dej nce ntxiv, thiab cov ntawv xov xwm dej hauv qab ntawm daim nyias nyias. daim nyias nyias yuav sparse, qhia txog cov nyhuv anti-seepage ntawm ntsug anti-seepage membrane Zoo heev txo.Nws tuaj yeem pom tau tias thaum lub ntuj tsim los tiv thaiv cov txheej txheem xws li cov av nplaum txheej muaj nyob hauv zos, seb cov av nplaum txheej tau muab tso rau hauv qab ntawm daim nyias nyias muaj qhov cuam tshuam zoo rau kev tiv thaiv kev tawm tsam ntawm daim nyias nyias.Thaum cov av nplaum txheej tau muab tso rau hauv qab ntawm daim nyias nyias, lub kaw impermeable barrier yog tsim.Piv nrog rau thaum cov av nplaum txheej tsis muab tso rau hauv qab ntawm daim nyias nyias, cov nyhuv anti-seepage tau zoo tuaj.Thaum cov av nplaum txheej tsis muab tso rau hauv qab ntawm daim nyias nyias, muaj ib txheej nyias permeable ntawm lub impermeable membrane thiab cov av nplaum txheej.Thaum cov dej ntws mus rau qhov chaw ib puag ncig, ib qho kev muaj zog seepage channel tsim.Thaum lub hauv qab ntawm daim nyias nyias nyob deb ntawm cov av nplaum txheej, lub thickness ntawm cov permeable txheej nce, cov nyhuv nkag mus, thiab cov nyhuv anti-seepage ntawm anti-seepage membrane tsis muaj zog.
Thaum lub hauv qab ntawm lub impermeable daim nyias nyias tsis nteg nyob rau hauv cov av nplaum txheej, cov hydraulic gradient nce nyob rau hauv lub cheeb tsam ze rau hauv qab ntawm lub lag luam wholesale textured geomembrane, tab sis txo nyob rau hauv cov av nplaum txheej.Piv nrog rau cov ntaub ntawv uas tsis muaj daim nyias nyias, lub hydraulic gradient ntawm cov av nplaum txheej nyob rau hauv qab ntawm daim nyias nyias nce, thiab hydraulic gradient ntawm cov av nplaum txheej tom qab daim nyias nyias txo, qhia tias cov dej ntws yog concentrated nyob rau hauv pem hauv ntej ntawm daim nyias nyias, thiab vim qhov kev hloov ntawm cov dej ntws, cov dej ntau ntws qab ntawm daim nyias nyias.Lub zog nce siab txo qhov concentration ntawm seepage ntawm ciam teb ntawm cov av txheej, uas yog tseem conducive rau stability ntawm seepage nyob rau hauv lub embankment.Tsis tas li ntawd, hydraulic gradient ntawm txhua txheej (tshwj tsis yog rau ib feem me me ntawm lub hauv qab ntawm daim nyias nyias) tseem me dua li qhov tso cai hydraulic gradient, yog li thaum lub hauv qab ntawm daim nyias nyias tsis npog nrog cov av nplaum txheej, kev nkag mus tsis ua haujlwm feem ntau. tsis tshwm sim, tab sis cov nyhuv anti-seepage ntawm ntsug daim nyias nyias yuav pom tseeb txo.
3. Cov nyhuv ntawm daim nyias nyias rupture.Thaum cov membrane puas lawm, cov seepage tshiab yuav raug tsim, ua rau lub redistribution ntawm seepage teb.Txoj kab infiltration tom qab daim nyias nyias tau nce ntxiv, thiab lub taub hau dej kuj nce ntxiv, tshwj xeeb tshaj yog nyob rau hauv qhov chaw puas.Lub anti-seepage nyhuv ntawm ntsug anti-seepage membrane yog obviously txo.Lub hydraulic gradient ua ntej thiab tom qab daim nyias nyias ua los ntawm LDPE geomembrane manufacturers yog tawg pom tseeb nce, thaum lub hydraulic gradient nyob rau hauv lwm qhov chaw txo, qhia tias cov dej ntws los ntawm daim nyias nyias yog tawg, tab sis qhov nce nyob rau hauv gradient tshwm sim los ntawm osmotic concentration muaj. me ntsis cawv.Thaum lub dike muab ib tug ntev seepage channel, nws yuav tsis cuam tshuam rau stability ntawm lub dike.Tsis tas li ntawd, hydraulic gradient ntawm lwm cov khaubncaws sab nraud povtseg raug txo, uas yog me dua li qhov tso cai hydraulic gradient, yog li thaum lub membrane puas lawm, osmotic tsis ua hauj lwm yuav tsis tshwm sim.
