1. Thaum nteg cov fiberglass geogrid los ntawm kev kho cov ntsia hlau, thawj kho ib qho kawg nrog cov ntawv npuag hlau thiab ntsia hlau rau ntawm cov substructure uas tau txau nrog nplaum txheej ntawm asphalt. Cov ntsia hlau tuaj yeem tua nrog rab rauj lossis ntsia rab phom, thiab tom qab ntawd daim phiaj ntev ntev thiab ua kom nruj hauv cov ntu, txhua ntu yog 2-5 metres ntev. Rau kev cog pob zeb pua hauv av, nws tuaj yeem faib raws qhov sib txawv ntawm qhov shrinkage sib koom tes. Txoj haujlwm ntawm cov ntsia hlau steel yog teem rau ntawm cov pob qij txha. Thaum cov grille yuav tsum nruj, nws cov lus qhia ncaj qha thiab kab rov tav yog nyob hauv qhov chaw muaj qhov nro.
2. Kev sib tshooj nrug deb ntawm lub grille yog: sib tshooj deb ntawm qhov sib txawv ntawm cov leeg ntev tsis pub tsawg tshaj 20 cm, thiab qhov sib nrug ntawm kab rov tav tsis tsawg tshaj 15 cm. Qhov ntsug sib tshooj yuav tsum ua raws li cov asphalt paving kev coj ua, thiab yav dhau los ib qho yuav tsum nyob siab tshaj tom qab.
3. Cov ntsia hlau tsis tuaj yeem raug ntsia rau ntawm daim fiberglass grille, kuj tsis tuaj yeem tsoo nws ncaj qha rau ntawm daim phiaj fiberglass nrog tus rauj. Tom qab kho tas, yog tias koj pom tias cov ntsia hlau tawg lossis cov hlau tsis ruaj lawm, koj yuav tsum kho nws dua.
4. Tom qab daim iav fiber ntau daim phiaj tau tso thiab tsau, nws yuav tsum tau sib xyaw kom tsawg thiab ruaj khov nrog lub log roj hmab. Ua tus grille lo rau saum npoo ntawm thawj txoj kev ruaj khov, tswj hwm kev nkag mus rau lub tsheb uas nqa sib xyaw, thiab txwv tsis pub lub tsheb tig, tsoo, thiab muab cov khoom pov tseg pov tseg rau ntawm txheej grille kom tiv thaiv kev puas tsuaj rau kev tsim kho fiberglass grille.
