(1) Daim Qauv Tsim Qauv: Qhov khi khi yog tsau rau ntawm cov yeeb nkab steel nrog cov hlau kab rov tav, thiab cov hlua hlau khi nrog hlua hlau. Txoj hlua khi yuav tsum tau teeb tsa ntawm tus ncej thaum rub sab hauv thiab sab nraud ncej. Txoj hlua khi khi tau npaj kab rov tav. Thaum nws tsis tuaj yeem muab cov kab rov tav, qhov kawg txuas nrog cov scaffold yuav tsum txuas mus rau hauv qab thiab tsis upwards.
(2) Cov kev yuav tsum tau ua: Cov chaw phab ntsa sib txuas tau npaj ua ob kauj ruam thiab peb spans, nrog ib qho chaw ntsug ntawm 4.5m, siv ob chav fasteners rau kev txuas. Scaffolding yuav tsum tau khi khov kho nrog lub cev loj ntawm lub tsev. Thaum chaw teeb tsa, sim ua kom ze rau qhov pom ntawm lub ntsiab li sai tau, thiab qhov deb deb ntawm qhov no yuav tsum tsis muaj ntau dua 300 hli. Nws yuav tsum tau teeb tsa los ntawm thawj tus kab ntawv loj loj hauv qab, hauv lub pob zeb diamond-zoo li kev npaj.
(3) Cov fasteners siv ntawm cov ntsiab lus khi khi yuav tsum ua kom tau raws li qhov yuav tsum tau ua, thiab yuav tsis muaj xoob xoob lossis khoov ntawm cov yeeb nkab steel.
