Thov ua kom haum raws li qhov chaw tsim kho. Cov txheej txheem hauv qab no yog rau siv:
1. Pre-construction xav tau
1 .1 Qhov kev tsim kho los tiv thaiv cov dej ntws tawm yog qhov tseem ceeb ntawm tag nrho qhov project. Yog li ntawd, kev tsim kho los tiv thaiv dej yuav tsum tau ua kom tiav nrog kev sib raug zoo ntawm kev ua haujlwm hauv pej xeem.
1.2 Cov ntaub ntawv siv hauv qhov project yuav tsum ua raws li qhov yuav tsum tau ua.
1.3 Vuam tshuab thiab vuam rods feem ntau yog siv rau cov ntaub ntawv siv cov khoom siv, thiab nyob rau hauv tshwj xeeb, extrusion vuam torches, siab ntsuas, thiab E-hom locks yuav tsum tau.
2. Cov kev xav tau rau kev tswj hwm qhov chaw tso ntawm qib pej xeem hauv paus:
2.1 Flatness: ± 2cm / m2, tiaj tus thiab ncaj.
2.2. Compaction degree: 95 feem pua, geomembrane tuaj yeem tso rau ntawm nws tom qab dov.
2.3. Ntev thiab hla txoj kab nqes: Qhov kev ncua deb thiab txoj kab nqes yuav tsum siab tshaj 2 feem pua.
2.4 Kev huv huv: yuav tsum tsis txhob muaj cov khib nyiab ntse xws li cov cag ntoo, cov pob zeb tawg, pob zeb, thiab pob zeb ua pob zeb hauv qhov tob ntawm 2.50cm.
3.Kev xav tau rau ntau qhov sib koom ua ke
3.1Anchoring ditch: Qhov luaj li cas ntawm cov kwj deg yog 30-50cm. Lub ditch anchoring yog kho HDPE geomembrane thiab cov txheej tiv thaiv geotextile. Tom qab HDPE geomembrane thiab txheej tiv thaiv geotextile tau muab tso, tam sim ntawd nias lub pob zeb ua pob zeb.
4.Laying kev tsim kho huab cua xav tau:
4.1 Qhov kub yog 5-40 degree . Xav txog qhov thermal expansion thiab contraction ntawm lub geomembrane, raws li kev paub, qhov tso ntawm geomembrane yuav tsum nruj dua thaum nws txias; nws yuav tsum tau so thaum nws kub; kub kub.
4.2 Hnub cua thiab los nag: kev tsim kho yuav tsum tau nres thaum lub zog cua siab tshaj qib 4 lossis hnub los nag; Thaum cua me me, cov hnab xuab zeb yuav tsum tau siv los nias lub geomembrane kom yooj yim rau kev tsim kho.
5. HDPE geomembrane kev tsim kho thiab kev teeb tsa
5.1 HDPE geomembrane kev tsim kho thiab kev teeb tsa
5.2 Txiav thiab Shipping:
Raws li cov ntaub ntawv ntsuas ntawm lub hauv paus nteg, txiav tawm cov bundles loj ntawm geomembrane, sau cov lej, thiab thauj mus rau qhov chaw tso raws li cov lej. Nco ntsoov tias geomembrane yuav tsum tsis txhob rub lossis rub thaum lub sijhawm thauj mus los kom tsis txhob raug stabbed los ntawm cov khoom ntse.
5.3 Kev tsim kho thiab kev teeb tsa ntawm HDPE geomembrane
5.3.1 Nws yuav tsum txuas mus rau hauv qab mus rau qhov chaw siab, tsis txhob rub nruj heev, thiab tawm ntawm 1.50 feem pua ntawm cov dej hauv zos thiab ncab. Qee lub sij hawm coj mus rau hauv tus account qhov tseeb ntawm qhov project, txoj kab nqes yog nteg los ntawm sab saum toj mus rau hauv qab.
5.3.2 Lub longitudinal pob qij txha ntawm ob daim ntawv uas nyob ib sab yuav tsum tsis txhob nyob rau hauv kab rov tav, thiab yuav tsum staggered los ntawm ntau tshaj 1M.
5.3.3 Qhov ntev ntawm qhov sib txuas yuav tsum yog ntau tshaj 1.50M deb ntawm lub pas dej da dej thiab ko taw khoov, thiab yuav tsum tau teem rau ntawm lub dav hlau.
5.3.4 Txoj kab nqes ua ntej thiab tom qab ntawd hauv qab ntawm daim teb.
5.3.5 Thaum tso txoj kab nqes sab, cov yeeb yaj kiab nthuav tawm yuav tsum yog qhov sib npaug ntawm txoj kab nqes max.
5.3.6 Slope nteg tswj: Ua ntej lub anti-seepage geomembrane yog nteg nyob rau hauv txoj kab nqes, thawj zaug xyuas thiab ntsuas qhov chaw nteg, thiab thauj cov anti-seepage membrane sib piv qhov luaj li cas nyob rau hauv lub warehouse rau thawj-theem anchoring ditch platform raws li qhov ntsuas qhov loj. Thaum tso, raws li qhov tseeb ntawm qhov chaw, txoj kev yooj yim ntawm "thawb" los ntawm sab saum toj mus rau hauv qab yog saws. Nws yuav tsum raug txiav kom tsim nyog nyob rau hauv qhov chaw kiv cua kom lub sab sauv thiab qis kawg yog khov kho.
5.3.7 Tswj kev tso rau hauv qab ntawm daim teb: Ua ntej tso cov khoom tiv thaiv geomembrane, xyuas thiab ntsuas qhov chaw nteg, thiab thauj cov ntaub thaiv npog nrog qhov sib txuam loj hauv lub tsev rau khoom mus rau qhov sib thooj raws li qhov ntsuas. loj: thaum tso, siv dag raws li ib qho kev taw qhia, "push shop".
5.3.8 Alignment thiab alignment: Lub nteg ntawm HDPE geomembrane, txawm nws yog ib sab txoj kab nqes los yog hauv qab teb, yuav tsum du thiab ncaj kom tsis txhob wrinkles thiab ripples, thiaj li mus dlhos thiab dlhos ob geomembranes. Qhov dav dav dav yog feem ntau txog 10cm raws li kev tsim qauv.
5.3.9 Kev tswj ntawm lamination: siv lub hnab xuab zeb los nias qhov sib dhos thiab ua kom zoo HDPE tiv thaiv zaj duab xis nyob rau lub sijhawm kom tiv thaiv kom tsis txhob raug rub los ntawm cua.
5.3.10 Tswj kev tso rau hauv qhov chaw nres nkoj: Nyob rau sab saum toj ntawm qhov chaw nres nkoj, cov npoo npoo los tiv thaiv cov dej ntws yuav tsum tau tshwj tseg raws li cov qauv tsim los tiv thaiv lub tog thiab ncab.
5.3.11 Longitudinal pob qij txha: ntu upslope yog nce, seem downslope down, thiab muaj txaus overlap length Ntau tshaj los yog sib npaug zos rau 15 cm
5.3.12 Txoj kev nthuav qhia zaj duab xis yuav tsum nyob rau hauv parallel mus rau lub siab tshaj plaws gradient kab.
6. Vuam ceev faj rau HDPE geomembrane.
6.1 Cov pob qij txha ntawm HDPE geomembrane yuav tsum tsis txhob muaj roj stains thiab hmoov av, thiab qhov sib tshooj ntawm HDPE geomembrane yuav tsum tsis txhob muaj cov khib nyiab xws li xuab zeb thiab xuab zeb. Thaum muaj cov khib nyiab, nws yuav tsum tau ntxuav ua ntej vuam.
6.2 Thaum pib vuam txhua hnub, ib qho 0.9mm × 0.3mm qauv yuav tsum tau sim ntawm qhov chaw ua ntej, thiab lub puab tsaig dav yuav tsum tsis pub tsawg tshaj 10cm, thiab kev kuaj tev thiab txiav. yuav tsum tau nqa tawm ntawm qhov chaw nrog lub tshuab tensile. Tom qab tus qauv tsim nyog, nws tuaj yeem hloov kho lub sijhawm ntawd. Zoo ceev, siab, thiab kub tsuas yog vuam. Hnub tim, lub sijhawm thiab qhov kub thiab txias yuav tsum tau cim rau ntawm tus qauv. Thaum lub sij hawm welding txheej txheem ntawm kub wedge welding tshuab, yuav tsum tau them nyiaj mloog mus rau lub lag luam ntawm lub vuam tshuab txhua lub sij hawm, thiab qhov ceev thiab kub yuav tsum tau zoo-tuned raws li qhov tseeb ntawm qhov chaw.
6.3 HDPE geomembrane welds yuav tsum tau ua kom zoo thiab zoo nkauj, tsis muaj plam vuam thiab dhia.
6.4 Thaum qhov ntev ntawm HDPE geomembrane tsis txaus, nws yuav tsum tau spliced nyob rau hauv txoj kev ntev. Kab rov tav weld yuav tsum tau welded ua ntej, thiab tom qab ntawd lub longitudinal seam yuav tsum tau welded. Qhov kev ncua deb ntawm kab rov tav welds yog ntau tshaj 50cm thiab yuav tsum yog T-puab, thiab yuav tsum tsis txhob hla.
6.5 HDPE geomembrane welds uas nyob ib sab yuav tsum tau staggered thiab overlapped kom ntau li ntau tau. Cov pob qij txha tsim ntawm daim nyias nyias yuav tsum yog T-puab, thiab tus ntoo khaub lig-zoo li yuav tsum tau txo kom tsawg. Qhov kev sib tshuam ntawm cov pwm ntev thiab cov welding yuav tsum tau ntxiv dag zog los ntawm ib qho extrusion welder.
6.6 Thaum welding zaj duab xis, nws tsis raug tso cai rau nias tawm qhov tawg. Thaum tso cov HDPE geomembrane, raws li qhov kub thiab txias hloov pauv hauv cheeb tsam thiab kev ua haujlwm ntawm HDPE geomembrane, cia qhov nthuav dav thiab qhov sib cog lus los ntawm qhov kub hloov pauv.
6.7 Thaum qhov kub ntawm lub tshuab vuam qhia los ntawm qhov ntsuas kub ntawm lub tshuab vuam txav tau qis dua 200 degree, nws yuav tsum tau muab tshem tawm nrog cov ntaub huv huv lossis paj rwb xov ua ntej vuam. Yog tias tsim nyog, nws yuav tsum tau rov polished.
6.8 Thaum cov pob qij txha ntawm HDPE geomembrane raug cuam tshuam los ntawm condensation, noo noo, sediment, thiab lwm yam, vuam yuav tsum tau nqa tawm tom qab kev kho mob.
6.9 Vuam tsis tuaj yeem ua thaum los nag lossis thaum muaj dej noo, dej lwg, lossis xuab zeb hnyav hauv cov pob qij txha, tshwj tsis yog muaj kev tiv thaiv.
