Anti-Seepage Structure nyob rau hauv Txoj Haujlwm Kev Npaj
Txoj kev tiv thaiv -seepage qauv ntawm geosynthetics nyob rau hauv landfill system feem ntau muaj peb seem, impervious txheej, txhawb txheej thiab tiv thaiv txheej.
GeomembraneMuab pov tseghdpe linerthiab GCL yog lub ntsiab tiv thaiv -seepage txheej, lub luag hauj lwm tseem ceeb yog los tiv thaiv cov kua los yog gas migration thiab to. Nws yog lub ntsiab lub cev ntawm impervious qauv.
Tam sim no, HDPE geomembranes thiab PVC geomembranes yog cov feem ntau siv hauv impervious engineering hauv Suav teb. BPM Geosynthetics tsuas yog tsim PEMuab pov tseghdpe liner.
Hauv kev tswj cov dej ntws ntawm cov dej cia thiab cov dej hauv dej, qhov dej me me tuaj yeem tso cai, ib qho - txheej txheej seepage yog ua haujlwm tau.
Nyob rau hauv cov kev tiv thaiv nruj heev -seepage tej yaam num , xws li evaporation oxidation pas dej thiab cov dej khib nyiab uas tsis tso cai rau xau, ntau - txheej impervious qauv yog tsim nyog.
Lawv feem ntau siv ob los yog ntau txheej ntawm geomembrane los yog GCL, cov kua dej geonet feem ntau paved nruab nrab ntawm lawv raws li cov kua txheej.
Txhawm rau tiv thaiv cov pob zeb hauv av thiab lwm yam khoom ntse los ntawm punctured geomembrane, geomembrane feem ntau yuav muab tso rau hauv geotextile raws li txheej tiv thaiv.
Yuav Ua Li Cas Tso Geomembranes hauv Landfill
Tso geomembranes cov txheej txheem
1) Thaum tso lubhdpe liner, muaj ntau yam yuav tsum tau xav txog, kub, ib puag ncig, tso cov kauj ruam.
Tom qab theem hauv qab ntawm qhov chaw pov tseg, cov dej hauv av yuav tsum tau khawb los ntawm txhais tes kom sau paj - cov kav dej raws li cov qauv tsim. Cov av seem yuav tsum tau thauj mus rau hauv qab ntawm qhov chaw pov tseg, thiab cov ntaub ntawv tsis muaj dej yuav tsum tau muab tso rau hauv qab mus rau saum.
2) Cov txheej txheem thev naus laus zis:
Reservoir hauv qab dav hlau rammed - 30cm tuab pebble dej hauv av diversion txheej - filament geotextile nteg (200g / m2) - kis tau 30cm tuab av nplaum txheej - kis bentonite cushion 4800g / m2-2mm tuab HDPE impermeable - filament geotextile nteg (600g / m2) - 2cm tuab nruab nrab coarse xuab zeb txheej - ntev Silk geotextile (200g / m2) -- 30cm tuab pebble leachate diversion txheej - filament geotextile 200g / m{20}} cov khoom pov tseg. Hauv kev tso cov HDPE impervious zaj duab xis, raws li cov xwm txheej tshwj xeeb ntawm qhov chaw tsim kho, nws feem ntau pib los ntawm txoj kab nqes ua ntej, thiab tom qab ntawd pib los ntawm hauv qab ntawm cov pob tseg. Nyob rau hauv txheej txheem ntawm txoj kab nqes los ntawm sab saum toj mus rau hauv qab, nws yog nqa tawm nyob rau hauv kev txiav txim los ntawm lub hauv qab mus rau sab saum toj thiab los ntawm sab saum toj mus rau hauv qab.
BPM Geomembrane Kev Pabcuam
Geomembraneswelding zoo yog lub ntsiab lus tseem ceeb los txiav txim siab qhov project impervious ua tiav los yog tsis tau, yog li xyuas kom meej tias geomembrane vuam zoo yuav yog ib qho tseem ceeb heev.
Dhau li ntawm qhov zoo tshaj plaws geomembranes,BPM lub tuam txhab muaj ib pab neeg tsim kho, tuaj yeem mus txawv teb chaws thiab muab cov kev pabcuam vuam vuam.
Peb cov welders tuaj yeem sib txuas lus ua lus Askiv zoo thiab muaj ntau xyoo ntawm kev tsim kho geomembranes txawv teb chaws kev paub.
