Lub tank cia khoom siv los khaws cov kua lossis roj av hlau kaw, lub tank cia khoom engineering yog roj av, tshuaj lom neeg, nplej thiab roj, khoom noj, kev tiv thaiv hluav taws, kev thauj mus los, metallurgy, kev tiv thaiv lub teb chaws thiab lwm yam lag luam tseem ceeb, nws cov kev cai yooj yim kuj nruj heev. Lub hauv paus av txheej yuav tsum ua tau raws li qhov xav tau ntawm tus nqi tsim ntawm lub peev xwm nqa tau, thiab nws yuav tsum tau kho nrog seepage thiab noo noo-proof, txwv tsis pub qhov xau yuav ua rau muaj kuab paug loj rau ib puag ncig, thiab cov dej hauv av yuav tuaj, thiab lub tank hlau yuav raug corroded. Yog li ntawd, HDPE roj tank impervious geomembrane yog cov khoom tsis pervious thiab noo noo-proof hauv qhov tsim qauv yooj yim ntawm lub tank cia khoom.
Thaj chaw tso roj av tso cov thev naus laus zis geomembrane impermeable:
1. Ua ntej lub tank roj impermeable geomembrane raug tso, daim ntawv pov thawj lees txais ntawm civil engineering yuav tsum tau txais.
2. Ua ntej txiav, qhov ntsuas qhov loj me yuav tsum tau ntsuas kom raug, HDPE geomembrane yuav tsum tau txiav raws li qhov txiav tiag tiag, feem ntau tsis yog raws li qhov loj me uas tau qhia, yuav tsum tau suav ib qho los ntawm ib qho, thiab sau tseg kom meej rau ntawm daim ntawv tshwj xeeb.
3. Yuav tsum siv zog ua kom tsawg dua qhov vuam, raws li lub hauv paus ntawm kev ua kom zoo, kom deb li deb tau kom txuag tau cov khoom siv raw. Nws kuj yooj yim los xyuas kom zoo.
4. Qhov dav ntawm qhov sib tshooj ntawm cov seam ntawm zaj duab xis thiab zaj duab xis feem ntau tsis tsawg dua 10cm, feem ntau yog li ntawd qhov sib txuas weld yog sib luag rau ntawm txoj kab nqes hav, uas yog, raws txoj kab nqes hav.
5. Feem ntau nyob rau hauv cov ces kaum thiab cov seem deformed, qhov ntev ntawm cov xov yuav tsum luv li sai tau. Tsuas yog cov kev xav tau tshwj xeeb, ntawm cov toj roob hauv pes uas muaj cov toj roob hauv pes ntau dua 1: 6, tsis pub dhau 1.5 meters ntawm qhov siab tshaj plaws lossis thaj chaw ntxhov siab, sim tsis txhob txhim kho cov vuam.
6. Thaum tso cov zaj duab xis impermeable rau hauv lub tank roj, yuav tsum tsis txhob muaj cov quav cuav. Thaum qhov kub qis, nws yuav tsum nruj thiab ua kom tiaj li sai tau.
7. Tom qab ua tiav qhov kev tso geomembrane impermeable, kev taug kev saum npoo ntawm daim nyias nyias, cov cuab yeej txav mus los, thiab lwm yam yuav tsum tau txo qis. Cov khoom uas tuaj yeem ua rau puas tsuaj rau daim nyias nyias impermeable yuav tsum tsis txhob muab tso rau ntawm daim nyias nyias lossis nqa ntawm daim nyias nyias kom tsis txhob muaj kev puas tsuaj rau daim nyias nyias.
