Kev siv cov kub-kuav los tiag U-puab steel ntawv pawg rau cov tsev loj

U-shaped sheet piles yog cov khoom siv thev naus laus zis tshiab uas tau qhia los ntawm Netherlands, Southeast Asia thiab lwm qhov chaw.Tam sim no lawv tau siv dav hauv tag nrho Pearl River Delta thiab Yangtze River Delta.Daim ntawv thov thaj chaw: cov dej ntws loj, hiav txwv cofferdams, kev tswj hwm dej hauv nruab nrab, kev tsim kho lub hauv paus, Txoj Kev Loj, txuas hniav, cov phiaj xwm hauv nroog thiab kev tsim kho thib peb ntawm wharf
Taw qhia rau daim ntawv thov zoo ntawm U-puab daim ntawv pawg:
1. Kev tuav loj.U-shaped prestressed qhob daim ntawv pawg ib pawg tuav ntu ntev txog 1 meter, uas nyob deb ntawm cov kab ntawv ib txwm siv thiab hom kab precast.
2. Cov qauv kev ntxhov siab hla ntu yog qhov zoo heev.U-shaped structural cross-section tsim yog siv los ua kom qhov siab ntawm ntu ntu thiab ntu ntu ntu ntawm inertia, yog li txhim kho qhov kev ntxhov siab ntawm cov qauv.
3. Cov txiaj ntsig kev lag luam pom tseeb.Cov qauv U-zoo li tau txais yuav, uas txo qis cov pob zeb siv hauv cov pawg no piv nrog cov ntawv zoo tib yam ntawm tib qhov siab ntawm qhov siab.Nyob rau tib lub sijhawm, U-zoo li daim ntawv pawg tau txais cov qauv tsim qauv, uas txo qhov kev ntxhov siab thiab kev txhawb zog ntawm qhov chaw ua kom tau raws li cov kev xav tau ntawm cov qauv kev ntxhov siab.Tus nqi ntawm kev txhawb nqa hauv cov qauv yog nce thiab tus nqi txo.Nyob rau tib lub sijhawm, cov av khaws qhov dav ntawm pawg pawg no ib pawg nce mus txog 1 meter, uas nyob deb ntawm hom pawg pawg.Raws li cov yam ntxwv saum toj no, tus nqi ntawm U-shaped prestressed pob zeb ua vaj huam sib luag yog li 30% qis dua li ntawm cov kab ntawv zoo tib yam, uas muaj txiaj ntsig zoo rau kev lag luam.
4. Hom qauv.Cov hom U-shaped prestressed pob zeb cov ntawv tuaj yeem xaiv tau yooj yim kom tau raws li qhov xav tau los ntawm kev siv qhov sib txawv qhov siab, cov ntaub ntawv txhawb zog, qhov ntau thiab qhov ntev ntawm pawg raws li qhov xav tau ntawm cov khoom siv ntawm pawg pawg.Ua tiav qhov kev ua kom zoo ntawm cov qauv hla ntu thiab ua kom muaj txiaj ntsig zoo tshaj plaws.
5. Lub sijhawm tsim kho yog luv.U-shaped prestressed qhob ntawv pawg txais yuav Hoobkas prefabricated hom, thiab qhov chaw tsim kho yog mechanized los tsim cov ntawv pawg phab ntsa, uas zoo heev shortens lub sij hawm tsim kho piv nrog ib txwm txoj kev.
6. Kev tsim kho tshuab, dav siv geological ntau yam, thiab zoo nkauj hla ntu tom qab tsim pawg
