Thaum lub sij hawm crawling welding txheej txheem, tus neeg teb xov tooj yuav tsum ua tib zoo saib xyuas qhov zoo ntawm vuam ob chav seam thiab kho qhov vuam kub thiab taug kev ceev raws li qhov kev hloov ntawm ib puag ncig kub txhua lub sijhawm. Kev tswj qhov kub thiab txias yog nruab nrab ntawm 250 degree thiab 300 degree, thiab kev taug kev ceev feem ntau yog 1-2 meters ib feeb. Koj tuaj yeem ua ntej kuaj vuam ntawm tus qauv thiab txiav txim siab cov txheej txheem tsim nyog ua ntej vuam raug cai. Thaum lub sij hawm welding, lub weld seam yuav tsum tau ua tib zoo tshuaj xyuas, feem ntau yog kom pom tias ob lub welds yog ntshiab thiab pob tshab, thiab seb puas muaj npuas, tsis muaj welds, melting point, los yog weld seam khiav npoo. Cov tsis tsim nyog yuav tsum tau kho los ntawm kev vuam. Txoj kev stitching ntawm cov ntaub yog lub luj tshib sib koom. Qhov zoo tshaj plaws suture koob sib nrug yog 6 millimeters. Lub suture txais yuav ib tug peb strand ob filament polyester stranded hlau nrog ib tug tawg lub zog ntawm Yinniu. Kev sib koom ua ke yuav tsum tsis muaj plua plav, roj, thiab noo noo, thiab qhov ntev ntawm qhov sib koom yuav tsum siab tshaj 10cm. Lub zog sib koom ua ke yuav tsum tsis pub tsawg dua 80% ntawm lub zog ntawm cov khoom siv niam txiv, thiab geotextile yuav tsum tau sewn nrog lub tshuab xaws tes tom qab splicing.
Kev sib koom ua ke ntawm PE geomembrane yuav tsum ua raws li cov hauv qab no: txo qis cov pob qij txha thiab ua tib zoo mus rau cov kev taw qhia ntawm kev ntxhov siab tensile; Kev sib koom tes yuav tsum zam cov ces kaum thiab muab tso rau ntawm qhov chaw tiaj tus.
8) Thaum muaj yin thiab yang cov ces kaum ntawm cov txheej txheem txhawb nqa, lawv yuav tsum tau muab sib npaug nrog lub vojvoog tsis pub tsawg dua 0.5m, thiab txheej txheej cushion geotextile yuav tsum tau ntxiv rau hauv PE geotextile zaj duab xis.
9) PE geomembrane yuav tsum tau kos rau saum cov qauv. Ib tug ntiav trench nrog ib tug tob ntawm 30cm thiab ib tug dav ntawm 30cm yuav excavated 50cm los ntawm txoj kab nqes ntug, thiab lub membrane kawg yuav muab faus thiab sau nrog compacted av. Cov hlau tuav kuj tseem siv tau los nias thiab kho cov ntsia hlau rau saum. Thaum riveting cov rau tes, shims yuav tsum tau ntxiv thiab kev tiv thaiv xeb yuav tsum tau ua.
