Cov hlau hlau prestressed yog cov hlau hlau zoo uas muaj cov pa roj carbon ntau thiab tsim los ntawm kev kho cua sov thiab kev ua kom txias. Nws yog tsim tshwj xeeb los ua kom tau raws li qhov yuav tsum tau ua ntawm cov pob zeb prestressed. Cov hlau hlau muaj cov pa roj carbon ntawm 0.65% txog 0.85% thiab cov pa sulfur thiab phosphorus tsawg dua 0.035%, ua kom muaj zog tensile zoo heev thiab ruaj khov. Txij li thaum nws tsim khoom lag luam thiab daim ntawv thov hauv xyoo 1920, cov hlau hlau prestressed tau dhau los ua kev txhim kho tseem ceeb thiab tam sim no muaj ntau yam khoom tsim nyog rau ntau yam kev siv.
Cov hlau hlau uas tau ua kom nruj muaj zog zoo heev, nrog rau lub zog tensile tsawg kawg nkaus ntawm 1470MPa. Cov qib zog tau hloov pauv ntau xyoo, hloov pauv ntawm thawj 1470MPa thiab 1570MPa mus rau tam sim no 1670-1860MPa. Lub cheeb ntawm cov hlau hlau kuj tau hloov pauv, ntawm 3-5 hli mus rau 5-7 hli. Cov lus qhia no muab kev ywj pheej thiab kev xaiv rau ntau yam haujlwm tsim kho, tso cai rau cov engineers xaiv lub zog thiab qhov loj me tsim nyog tshaj plaws rau lawv daim ntawv thov tshwj xeeb.
Kev lag luam hlau hlau prestressed muaj ntau yam khoom nrog cov yam ntxwv sib txawv kom tau raws li qhov xav tau sib txawv. Cov no suav nrog hlau txias rub, hlau ncaj thiab tempered, hlau tsis so, hlau galvanized, hlau scored, thiab lwm yam. Cov khoom no yog lub hauv paus ntawm cov hlau prestressed strands thiab tau dhau los ua cov hlau prestressed siv dav tshaj plaws hauv ntiaj teb. Cov khoom sib xyaw no tso cai rau cov neeg siv nrhiav qhov sib phim zoo tshaj plaws rau lawv cov kev xav tau tshwj xeeb, kom ntseeg tau tias muaj kev ua haujlwm zoo tshaj plaws thiab kev ua tau zoo tshaj plaws.
Ib qho ntawm cov yam ntxwv tseem ceeb ntawm cov hlau prestressed yog nws lub zog tensile siab. Lub zog no, ua ke nrog kev tswj hwm nruj ntawm cov pa roj carbon, sulfur thiab phosphorus cov ntsiab lus, ua kom ntseeg tau tias kev ua haujlwm zoo thiab kev ruaj khov ntawm cov pob zeb prestressed. Lub peev xwm ntawm cov hlau kom raug kho cua sov thiab ua haujlwm txias ntxiv txhim kho nws cov khoom siv kho tshuab, ua rau nws tiv taus corrosion, qaug zog thiab kev ntxhov siab. Cov hlau prestressed yog tsim los tiv taus qhov siab heev, muab kev ruaj khov ntev thiab lub zog rau cov qauv.
Cov xov hlau prestressed siv dav hauv kev lag luam kev tsim kho. Nws feem ntau yog siv rau hauv cov qauv prestressed xws li choj, tsev siab, qhov av, txoj kev tsheb ciav hlau, thiab txawm tias hauv kev lag luam precast concrete. Lub zog thiab kev ntseeg tau ntawm cov xov hlau ua lub luag haujlwm tseem ceeb hauv kev txhawb nqa cov qauv no, kom ntseeg tau tias lawv tiv taus cov zog sab nraud xws li av qeeg thiab cov khoom hnyav. Nws cov kev ua tau zoo tshaj plaws, kev nyab xeeb thiab kev ruaj khov piv rau cov ntaub ntawv txhawb nqa ib txwm ua rau nws yog thawj qhov kev xaiv rau cov haujlwm tsim kho thoob ntiaj teb.
Xaus lus, cov hlau hlau prestressed yog ib yam khoom siv tau ntau yam thiab txhim khu kev qha uas tau siv dav hauv kev lag luam kev tsim kho. Nrog nws cov yam ntxwv tshwj xeeb, ntau yam khoom thiab ua raws li cov lus qhia nruj, nws muab lub zog thiab kev ruaj khov uas xav tau rau cov ntawv thov prestressed concrete nyuaj. Txawm hais tias nws yog choj, tsev lossis lwm yam qauv, cov hlau hlau prestressed muab cov engineers thiab cov neeg ua haujlwm tsim kho nrog kev daws teeb meem ntseeg siab rau kev tsim cov qauv ruaj khov thiab kav ntev.
