4. Thaum lub sij hawm tso HDPE geomembrane, cov khoom tsim tawm yuav tsum zam kom deb li deb tau.Thaum tso HDPE geomembrane, qhov nthuav dav deformation tshwm sim los ntawm kev hloov pauv kub yuav tsum tau tshwj tseg raws li kev hloov pauv hauv cheeb tsam thiab qhov kev ua tau zoo ntawm HDPE geomembrane.Tsis tas li ntawd, qhov kev nthuav dav ntawm geomembrane yuav tsum tau tshwj tseg raws li qhov chaw struts thiab tso geomembrane kom haum rau qhov tsis sib xws ntawm lub hauv paus.
5. Tom qab HDPE geomembrane tso, taug kev ntawm daim nyias nyias thiab cov cuab yeej tuav yuav tsum raug txo kom tsawg.Cov khoom uas tuaj yeem tsim kev puas tsuaj rau HDPE geomembrane yuav tsum tsis txhob muab tso rau ntawm geomembrane lossis nqa ntawm geomembrane kom tsis txhob muaj kev puas tsuaj rau HDPE membrane.
6. Txhua tus neeg ua haujlwm ntawm qhov chaw tsim kho HDPE zaj duab xis yuav tsum tsis txhob haus luam yeeb, hnav khau nrog rau cov ntsia hlau lossis cov khau khau siab heeled mus taug kev ntawm qhov chaw ua yeeb yaj kiab, lossis koom nrog txhua yam uas yuav ua rau cov yeeb yaj kiab tsis zoo.
7. Tom qab HDPE geomembrane tau muab tso rau thiab ua ntej txheej txheej tiv thaiv, ib lub hnab xuab zeb 20-40Kg yuav tsum muab tso rau ntawm lub ces kaum ntawm daim nyias nyias txhua 2-5m los tiv thaiv cov geomembrane los ntawm cua.
8. HDPE geomembrane yuav tsum yog ntuj thiab ze rau cov txheej txheem txhawb nqa, thiab yuav tsum tsis txhob muab quav lossis tshem tawm hauv huab cua.
9. Thaum lub geomembrane yog tsim nyob rau hauv cov seem, txheej sab sauv yuav tsum tau them nyob rau hauv lub sij hawm tom qab tso, thiab lub sij hawm exposed nyob rau hauv huab cua yuav tsum tsis txhob ntau tshaj 30 hnub.
Kev thauj mus los ntawm HDPE geomembrane yuav tsum tau ua raws li tus qauv tsim.Nyob rau hauv cov chaw uas muaj qhov nyuaj nyob rau hauv qhov project, lub tsev tsim kho yuav tsum tawm tswv yim lwm txoj kev anchoring, uas yuav tsum tau ua tom qab tau txais kev tso cai los ntawm lub tsev tsim thiab saib xyuas.

HDPE geomembrane vuam yuav tsum:

1. Qhov sib tshooj ntawm HDPE geomembrane weld yuav tsum tsis muaj av, xuab zeb, dej (xws li cov lwg) thiab lwm yam impurities uas cuam tshuam rau vuam zoo, thiab yuav tsum tau muab ntxuav kom huv thaum vuam.
2. Thaum pib vuam txhua txhua hnub (thaum sawv ntxov thiab tom qab noj su), kev sim vuam yuav tsum tau ua nyob rau hauv qhov chaw ua ntej, thiab kev vuam raug cai tsuas yog ua tau tom qab nws tsim nyog.
3. Lub HDPE geomembrane yuav tsum tau welded los ntawm ob chav khiav kub-melt vuam tshuab, thiab cov extrusion welding los yog kub-cua phom vuam yuav tsum tsuas yog siv nyob rau hauv qhov chaw uas kho, npog lossis kub-melt vuam tshuab tsis tuaj yeem ncav cuag.
4. Thaum lub sij hawm tsim kho, kev ua haujlwm kub thiab ceev ntawm lub tshuab vuam yuav tsum tau hloov kho thiab tswj txhua lub sijhawm raws li qhov kub thiab txias thiab cov khoom siv.
5.HDPE zaj duab xis ntawm qhov vuam yuav tsum tau welded tag nrho, thiab yuav tsum tsis txhob muaj kev vuam cuav, tsis muaj vuam lossis vuam ntau dhau.Qhov txuas ob txheej ntawm HDPE geomembrane yuav tsum tau lapped tiaj tus thiab maj mam.

Weld zoo tswj

Nrog rau kev txhim kho kev txhim kho, nws yuav tsum tau xyuas qhov vuam zoo ntawm HDPE zaj duab xis nyob rau lub sijhawm, thiab kho cov vuam nrog cov phom cua kub lossis cov phom yas vuam txhua lub sijhawm kom tsis muaj vuam thiab qhov vuam tsis raug.Cov txheej txheem tshwj xeeb yog raws li hauv qab no:
1.Qhov kev tshuaj xyuas yog ua nyob rau hauv peb kauj ruam, uas yog kev tshuaj xyuas qhov muag, kev tshuaj xyuas kev nce nqi thiab kev kuaj kev puas tsuaj.
2. Kev soj ntsuam pom: xyuas seb ob lub welds puas tiaj tus, meej, wrinkle dawb, pob tshab, slag dawb, npuas, xau taw tes, melting point lossis weld hlaws.
Kev tshuaj xyuas qhov pom yog tsuas yog ua tib zoo tshuaj xyuas cov tsos ntawm cov geomembrane nteg, weld zoo, T-shaped vuam, substrate khib nyiab, thiab lwm yam. Txhua tus neeg ua haujlwm tsim kho yuav tsum ua cov haujlwm no hauv txhua qhov kev tsim kho.
3. Ntxiv nrog rau kev tshuaj xyuas qhov muag, kev tshuaj xyuas lub tshuab nqus tsev yuav tsum tau txais kev pom zoo rau qhov nruj ntawm txhua qhov vuam, thiab kev tshuaj xyuas tus kheej yuav tsum tau ntxiv dag zog rau cov khoom uas tsis tuaj yeem kuaj xyuas los ntawm lub tshuab nqus tsev.
4. Lub zog nce nqi pom los ntawm kev nce nqi siab yog 0.25Mpa, thiab tsis muaj cua nkag rau 2 feeb.Xav tias cov khoom coiled yog mos thiab yooj yim rau deform, qhov tso cai poob siab yog 20%
5. Thaum ua kev ntsuas tensile ntawm cov qauv coj los ntawm ob txoj kev tsheb ciav hlau vuam, tus qauv yog tias cov vuam tsis raug torn tab sis niam yog torn thiab puas thaum lub sij hawm tev thiab shear xeem.Lub sijhawm no, qhov vuam tsim nyog.Yog tias tus qauv tsis tsim nyog, ib daim thib ob yuav tsum tau muab los ntawm qhov qub weld.Yog tias peb daim tsis tsim nyog, tag nrho cov vuam yuav tsum rov ua dua.
6. Cov qauv xeem dhau qhov kev xeem yuav tsum raug xa mus rau Tus Tswv Cuab, Tus Kws Cob Qhia General thiab cov koom haum cuam tshuam rau kev ua ntaub ntawv.
7. Cov teeb meem uas pom nyob rau hauv kev soj ntsuam pom, kev nce nqi thiab kev kuaj kev puas tsuaj yuav tsum tau kho raws sij hawm.Cov uas tsis tuaj yeem kho tau tam sim ntawd yuav tsum raug cim los tiv thaiv kev tsis tuaj yeem thaum kho.
8. Nyob rau hauv kev tshuaj ntsuam xyuas, nyob rau hauv cov ntaub ntawv ntawm tsis xws luag xws li qhov nyob rau hauv daim nyias nyias thiab ploj welding, faulty welding thiab puas thaum lub sij hawm welding, tshiab lub hauv paus hlau yuav tsum tau siv los kho nyob rau hauv lub sij hawm, thiab txhua sab ntawm lub kho caws pliav yuav tsum tshaj lub puas ib feem ntawm 10-20cm.Ua cov ntaub ntawv.
9. Rau qhov kho qhov vuam, kev tshuaj xyuas kom pom tseeb yuav tsum tau ua feem ntau, thiab kev tso tawm yuav tsum tau ua tom qab kev kho kom ntseeg tau tias muaj kev ntseeg siab.
