Kev sib txuas lus ntauwd yuav sau cov khoom ntim. Lub thawv, feem npe npe, naj npawb thiab qhov hnyav yuav tsum qhia rau 3 lub thawv. Txhawm rau tshuaj xyuas cov chaw tom qab lub chaw. Cov ntaub ntawv zoo yog ncaj qha cuam tshuam nrog lub ntsiab ntawm qhov zoo ntawm qhov project. Cov ntaub ntawv yog lub hauv paus ntawm qhov project ntauwd.
Tus kws cog lus yuav tsum sau daim ntawv thov kev pabcuam thiab cov ntaub ntawv yuav tshwm. Cov hlau thiab lwm yam ntaub ntawv ua pov thawj zoo daim ntawv foos thiab cov ntawv sim yog xa mus rau chav saib xyuas. Cov ntaub ntawv nyob sab nraud yuav raug suav ua ke nrog cov chaw tsim kev cog lus thiab chav cog lus, thiab chav saib xyuas yuav tau txais daim ntawv soj ntsuam. Xav txog qhov loj me, ntau yam, tus naj npawb, qhov tshwj xeeb thiab galvanized tuab ntawm cov hlau ntau ntau yam, seb nws ua tau raws li cov qauv tsim thiab cuam tshuam cov qauv ntawm kev ntsuas tus kheej, ntsuas tus kheej thiab ntsuas raws li cov kev cai hauv tebchaws, qhov yuav tsum tau ua raws rau lub teb chaws cov kev cai.
1. Txawb xov tooj kev sib txuas lus ntau tswj cov ntaub ntawv
2. Lub tshuab hluav taws xob yuav tsum yog E43 zoo yuav tsum ua raws li cov cai ntawm GB5118-85, qhov zoo ntawm flux yuav tsum tau ua raws li cov kev cai ntawm GB1308-85; lub chaw haujlwm meej mom yuav tsum paub meej thiab lees paub daim ntawv thov thiab tshaj tawm daim ntawv thov; 2 yog tias cov ntaub ntawv tshiab tau txais yuav.
3. Tus lej, txheej txheem, thiab cov khoom sib xyaw yuav tsum ua tiav cov qauv tsim.
4. Hais txog cov khoom siv thiab cov khoom siv steel, kuaj yuav tsum raug xa mus rau kev kuaj xyuas.
Cov hlau yuav tsum muaj daim ntawv pov thawj zoo, thiab cov hlau tsis zoo yuav tsum ua raws li cov cai ntawm GB700-88GB1591-94 thiab YB168-70. Thiab ua tau raws li qhov yuav tsum tau ua ntawm cov ntaub ntawv tsim qauv, yog tias chav saib xyuas tau ua xyem xyav txog cov khoom, nws yuav tsum tau ua raws li cov qauv hauv tebchaws, thiab qhov yuav tshwm sim tuaj yeem siv raws li lub teb chaws tus qauv thiab cov ntaub ntawv tsim.
Yog tias muaj kev deformation, qhov loj me thiab kev qhia ntawm 5 yam yuav tsum ua raws li cov qauv tsim. Kev kho tsim nyog thiab kev tivthaiv yuav tsum tsis txhob raug txias thaum ntsuas kub yog qis dua -16 ° C. Yog tias muaj lub delamination lossis cov khoom tawg ntawm lub pob tawg, qhov tob ntawm cov xeb, pitting lossis kos ntawm 6 cov khoom steel yuav tsum tsis txhob ntau tshaj ib nrab ntawm qhov tsis zoo deflection tus nqi ntawm cov steel tuab. Pawg saib xyuas yuav tham thiab muab pov tseg nrog chav ntsuas cuam tshuam. Cov ntaub ntawv thiab kev ua haujlwm zoo ntawm cov hlua hlau thiab cov hlua steel (rub cov hlau) siv rau 7 rub ntauwd ntawm kev sib txuas lus ntauwd yuav tsum tau raws li cov kev cai hauv tebchaws thiab cov ntaub ntawv tsim qauv.
