Kev siv cov raj xa dej uas muaj qhov khoob tau hloov pauv kev lag luam kev tsim kho, muab ntau yam txiaj ntsig ntawm kev ua kom ruaj khov, kev hloov pauv tau yooj yim thiab kev siv nyiaj tsawg. Cov raj xa dej no muaj cov qhov khoob sab hauv ntawm ntau yam duab, ua kom muaj zog thiab ruaj khov thaum txo qhov hnyav thiab txhim kho kev yooj yim ntawm kev tsim qauv. Cov blog no yuav nkag mus rau ntau qhov zoo ntawm cov raj xa dej uas muaj qhov khoob, qhia txog lawv qhov tseem ceeb hauv cov haujlwm tsim kho niaj hnub.

Txhim kho kev ruaj khov ntawm cov qauv

Cov kav dej hollow-sectionLawv paub txog lawv qhov sib piv ntawm lub zog thiab qhov hnyav zoo heev. Cov khoom no yog los ntawm nws cov duab tshwj xeeb, uas tiv taus kev sib zog thiab kev khoov. Los ntawm kev faib cov khoom thauj kom sib npaug, cov kav dej no txo qhov kev pheej hmoo ntawm kev hloov pauv lossis kev tawg hauv cov xwm txheej hnyav, ua rau lawv tsim nyog rau cov haujlwm tseem ceeb xws li choj, tsev siab thiab chaw ua si.

Lub zog ntawm cov kav dej hollow-section structural pipes tso cai rau cov neeg tsim qauv thiab cov kws kes duab vajtse los tsim cov qauv uas ntev dua thiab muaj peev xwm nqa tau ntau dua, ua rau cov qauv zoo nkauj, muaj zog, thiab tuaj yeem tiv taus lub sijhawm sim. Tsis tas li ntawd, nws qhov kev ruaj khov zoo heev ua rau nws yog qhov kev xaiv zoo tshaj plaws hauv cov cheeb tsam uas muaj av qeeg, ua kom ntseeg tau tias cov neeg nyob hauv cov cheeb tsam uas muaj av qeeg muaj kev nyab xeeb.

Kev tsim qauv ntau yam

Ib qho ntawm cov txiaj ntsig tseem ceeb ntawm cov kav dej hollow-section yog qhov ua tau ntau yam ntawm lawv txoj kev tsim. Ntau yam duab muaj, xws li rectangular, round thiab square, tso cai rau cov kws kes duab vajtse thiab cov engineers los tsim cov qauv zoo nkauj uas sib xyaw ua ke nrog lawv ib puag ncig. Lub peev xwm los sib xyaw ua ke ntau yam duab thiab qhov ntau thiab tsawg ntxiv txhim kho kev ywj pheej ntawm kev tsim qauv kom tau raws li qhov xav tau ntawm txhua qhov project.

Cov kav dej uas muaj qhov khoob kuj tseem ceeb heev rau kev tsim kho kom ruaj khov. Lawv qhov sib dua thiab tsis hnyav ua rau cov khoom siv uas yuav tsum tau siv los tsim ib lub tsev, yog li ntawd thiaj li txo tau qhov cuam tshuam rau ib puag ncig. Tsis tas li ntawd xwb, lawv qhov sib txawv ua rau yooj yim rau kev sib dhos thiab kev rhuav tshem, ua rau lawv siv tau dua thiab txo cov khib nyiab thaum lub sijhawm tsim kho thiab rhuav tshem.
