Txij li thaum 50s ntawm lub xeem xyoo pua tau pib yuav cov txheej txheem kev lag luam los tsim vaj tse, thiab ntau yam qauv kev ua haujlwm tau tsim. Hauv xyoo 1968, Nyij Pooj tso rau pem hauv ntej lub tswv yim ntawm "Kev muaj tsev nyob" (feem ntau ntawm cov vaj tse yog qauv thiab pib tsim cov tsev ua ntej Txij li thaum kawg ntawm 60s ntawm lub xyoo pua xeem. Thaum xaus ntawm 90s, kev sib faib ntawm cov qauv steel nyob rau hauv cov tsev ua ntej hauv Nyij Pooj tau txog 71% (18% rau cov neeg ua kom precast qhob vaj txheem).
Nws tsis yog qhov nyuaj kom pom tias qhov kev ua tiav ntawm prefabricated vaj tsev yog premised nyob rau hauv industrialization ntawm vaj tse, thiab steel qauv prefabricated vaj tse yuav tsum tau integrate cov steel qauv, ib tug tseem ceeb cim ntawm lub Modernization ntawm lub vaj tsev kev lag luam.
Thaum kawg ntawm lub xyoo pua xeem, Tuam Tshoj kuj tau pib tshawb fawb thiab tshawb fawb ntawm prefabricated steel qauv vaj tsev. Xyoo 1999, Lub Xeev Pawg Neeg Saib Xyuas tau tshaj tawm "Daim Ntawv Ceeb Toom Txog Ntau Qhov Kev Pom Zoo ntawm Kev Txhawb Kev Txhim Kho Kev Lag Luam Kev Lag Luam thiab Kev Txhim Kho Vaj Tsev Zoo", uas tau ua kom pom tseeb tias kev txhim kho thiab kev tshawb fawb ntawm cov txheej txheem tshiab yuav tsum muaj zog, thiab kev siv cov Lub teeb steel ncej qauv thiab lawv cov kev txhawb nqa prefabricated daim hlau yuav tsum tau tsim thiab txhawb nqa.
Los ntawm 2016, Tuam Tshoj cov tsev ua haujlwm ua ntej Steel qauv suav nyiaj rau tsuas yog kwv yees li 4% ntawm cov qauv hlau tsim, thiab feem ntau ua rau cov tsev pej xeem. Nrog nthwv dej hauv tsev nyob rau xyoo 2016 rov qab los, lub koom haum Central ntawm cov kev tswj hwm hauv lub Ob Hlis 2016 "ntau txoj kev tsim kho ntawm txoj kev npaj hauv nroog thiab kev tsim kho" yog qhov tsim nyog yuav tsum muaj zog Txhawb cov tsev ua ntej ua ntej thiab mob siab thiab ruaj khov txhawb nqa cov vaj tse steel qauv. Tom qab, tus qauv hauv tebchaws "kev ua haujlwm ua ntej tsim qauv hlau qauv" (GB / t} {4}}) kuj tseem raug siv thaum lub Rau Hli 1, 2017.
Feem ntau, qib tam sim no ntawm cov tuam tsev steel sib dhos ntawm Tuam Tshoj cov tsev nyob yog tsawg, nws tseem yog lub peev xwm txhim kho.
