Cov kev txhawb nqa yog ib feem ntawm cov txheej txheem steel, tab sis nws kuj yog ib qho tseem ceeb. Nyob rau hauv lub portal ncej steel qauv, lub kaw lus muaj lub luag haujlwm tseem ceeb, feem ntau hauv:
Ua kom muaj kev ruaj ntseg ntawm tag nrho cov qauv thiab tus kheej cov khoom, hloov cov nyhuv kab rov tav mus rau lub hauv paus thiab auxiliary installation engineering, thiab lwm yam. Rau cov qauv nrog complex dav hlau layout, cov kev pab txhawb nqa system kuj yog conducive rau kev hloov kho ntawm cov txheej txheem nruj, kom lub cov qauv sib npaug sib npaug thiab tsim nyog, thiab txhim kho nws txoj kev ncaj ncees.
1. Txhawb kev teeb tsa cov cai
Nyob rau hauv lub gantry nruj thav duab steel qauv, cov txheej txheem kev txhawb nqa tuaj yeem muab faib ua ru tsev kab rov tav kev txhawb nqa, kem kev txhawb nqa thiab lwm yam kev pabcuam txhawb nqa.
Cov hauv paus ntsiab lus rau kev teeb tsa kev txhawb nqa yog raws li hauv qab no:
(1) Hloov cov load longitudinal kom meej, tsim nyog thiab yooj yim, thiab txo txoj kev sib kis kom ntau li ntau tau;
(2) Ua kom muaj kev ruaj ntseg ntawm cov txheej txheem sab nraud ntawm lub dav hlau, thiab muab cov ntsiab lus txhawb nqa sab nraud rau kev ruaj ntseg ntawm cov qauv thiab cov khoom;
③ Yooj yim installation ntawm cov qauv;
④ Ua tau raws li qhov yuav tsum tau muaj lub zog thiab nruj, thiab muaj kev sib raug zoo.
Nyob rau hauv lub gantry nruj thav duab steel qauv tsev, muaj qee cov kev cai thiab cov kev cai rau ntau hom kev txhawb nqa.
