Nyob rau hauv xyoo tas los no, nrog kev txhawb zog ntawm lub teb chaws rau cov tsev prefabricated, precast qhob Cheebtsam tau dhau los ua ib qho tseem ceeb hauv kev tsim cov tsev prefabricated.Hebei XIndadi tau tsom mus rau kev tshawb fawb thiab kev loj hlob ntawm "tsawg zog noj, ntsuab, ntse tsim technology thiab khoom siv rau prefabricated qhob" rau 18 xyoo, ua raws li txoj kev loj hlob lub tswv yim ntawm kev siv technology tshiab, thiab nws tus kheej tsim peb tiam ntawm cov ntse ntau lawm kab rau prestressed composite panels.

Cov kab ntau lawm muaj xws li pwm lub rooj tu, kos npe, roj txau, sab pwm thiab muab faib pwm kev teeb tsa, txhim kho kev txhim kho, embedded ib feem installation, prestressing, ntaub vibration thiab compaction, tivthaiv xov, zaj duab xis npog thiab kho, tshem tawm pwm, prestressed reinforcement txiav. , thiab cov khoom lifting.Cov khoom tiav tiav muaj qhov ua tau zoo thiab cov qauv kev ruaj ntseg thiab yog cov khoom lag luam zoo hauv cov khoom siv hauv tsev prefabricated.
