HOLLOW-Ntu Cov Khoom Siv Kav Dej rau Kev lim dej kab
Ntsib thawj zaug
Kev siv ntawm OF seem cov qauv txheej txheem tau hloov kho cov kev lag luam tsim kho, muab ntau cov txiaj ntsig zoo ntawm cov qauv kev ntseeg, versatility thiab nqi zog. Cov kav dej no cov kav dej sab hauv hollow cov duab ntawm ntau cov duab, kom muaj zog ntawm cov qauv muaj zog thiab ruaj khov thaum txo qhov hnyav thiab kev txhim kho kev tsim nyog. Cov blog no yuav ua rau muaj ntau qhov zoo ntawm kev sib tw Hollow cov qauv txheej txheem, qhia txog lawv qhov tseem ceeb hauv kev tsim kho niaj hnub no.
Txhim Kho Cov Qauv Txheej Txheem
HOLLOW-NTU-NTU COV KAUV TXUJ CI PIPESyog paub rau lawv lub zog zoo tshaj plaws-rau-qhov hnyav piv. Cov cuab yeej cuab tam no tau los ntawm nws cov cim kev sib txawv ntawm cov duab, uas tiv taus compressive thiab cov rog dabtsi yog khoov. Los ntawm cov neeg muaj mob fally, cov kav dej no txo qis kev pheej hmoo ntawm kev tawm tsam xws li cov choj tseem ceeb, cov vaj tse tseem ceeb thiab cov chaw ua si muaj kev sib tw.
Lub zog xam tau ntawm cov tsiaj ntawv hollow-seem uas tso cov qauv nrog kev pom dua tshiab, ua kom muaj lub suab tsis pom kev, thiab tuaj yeem tiv thaiv lub sijhawm. Tsis tas li ntawd, nws qhov kev xaiv tau zoo tshaj plaws ua rau nws xaiv qhov zoo tshaj plaws hauv thaj av hauv av qeeg hauv av qeeg hauv av qeeg hauv av qeeg.

Hydrostatic Kev Ntsuam Xyuas
Tsim Qauv
Ib qho ntawm cov ntsiab lus tseem ceeb ntawm cov hollow-seem cov qauv kav dej yog cov versatility ntawm lawv tus qauv. Qhov ntau yam ntawm cov duab muaj, xws li cov duab plaub, puag ncig thiab square, tso cai rau cov qauv kws kos duab uas muab sib xyaw nrog lawv ib puag ncig. Lub peev xwm los ua ke sib txawv cov duab thiab ntau thiab tsawg ntxiv txhim kho kev tsim qauv kom tau raws li cov kev xav tau ntawm txhua qhov project.
Hollow tshooj cov qauv kev kav tseem ua si ib lub luag haujlwm tseem ceeb hauv kev coj ua tsim tsev. Lawv lub teeb yuag txo cov khoom uas xav tau los ua tus qauv, yog li txo kev cuam tshuam ib puag ncig. Tsis tas li ntawd, lawv cov kev sib xyaw ua ke tso cai rau kev sib dhos yooj yim thiab cais tawm, ua rau lawv rov ua dua tshiab thiab txo cov khib nyiab ib puag ncig thaum kev tsim kho thiab rhuav tshem.
Nqi zog-ua hauj lwm
Ntxiv nrog rau cov txheej txheem thiab cov qauv tsim qauv thiab cov qauv hollow cov qauv txheej txheem muaj cov nqi tseem ceeb ua tau zoo. Qhov xav tau kev pab txhawb cov khoom siv tau txo qis, tshem tawm qhov xav tau ntawm lub zog lub zog, ua rau muaj kev txuag nyiaj tag nrho. Lawv lub teeb yuag kuj tseem txo cov nqi thauj khoom, ua rau lawv xaiv cov kev xaiv nyiaj txiag rau cov phiaj xwm ntawm cov nyiaj txiag nruj.
Cov kav dej no tseem muab cov khoom siv nyiaj tau ntev los ntawm lawv cov kev saib xyuas zoo dua thiab cov kev saib xyuas tsawg. Their resistance to corrosion and environmental factors can reduce repair and replacement costs throughout the life of the structure. Ib qho ntxiv, lawv yooj yim rau kev teeb tsa, uas txo tus nqi ua haujlwm, tso cai tsim kho kom tiav rau kev ua tiav raws sijhawm.
Hauv kev xaus
Hollow ntu qauv qauv kev sib pauv tau hloov pauv cov kev tsim kho kev tsim kho, muab cov versoncelity txhim kho thiab them tus nqi zoo. Los ntawm kev ua tiav qhov zoo tshaj plaws sib npaug ntawm lub zog thiab qhov hnyav, cov kav dej muab tsis muaj kev ruaj ntseg thaum cia cov kws kos duab thiab engineers los qhia txog lawv lub tswv yim. Tsis tas li ntawd, lawv cov khoom ua kom ruaj khov pab txhawb rau kev coj ua tsev ib puag ncig. Raws li kev tsim kho kev tsim kho thoob ntiaj teb txuas ntxiv mus ntxiv, Hollow ntu qauv kev coj ua yuav txuas ntxiv mus ua cov cuab tam zoo tshaj plaws hauv tsev thiab cov qauv ruaj khov uas yuav sawv ntawm lub sijhawm.
