Underwater structural reinforcement plays lub luag haujlwm tseem ceeb hauv marine engineering thiab kev saib xyuas hauv nroog. Iav fiber ntau lub tes tsho, underwater epoxy grout thiab epoxy sealant, raws li cov ntaub ntawv tseem ceeb nyob rau hauv underwater reinforcement, muaj cov yam ntxwv ntawm corrosion kuj, siab zog thiab ntev kev pab cuam lub neej, thiab yog dav siv nyob rau hauv engineering xyaum. Daim ntawv no yuav qhia cov yam ntxwv ntawm cov ntaub ntawv no, xaiv cov hauv paus ntsiab lus thiab cov txheej txheem tsim kho.
I. Lub tes tsho iav Fiber
Lub tes tsho iav fiber ntau yog ib yam ntawm cov khoom siv hauv qab dej, thiab nws cov khoom tseem ceeb yogiav fiberthiabresin. Nws muaj kev tiv thaiv corrosion zoo heev, siab zog thiab yooj yooj yim, uas tuaj yeem ua kom muaj peev xwm ua tau zoo thiab kev ua haujlwm seismic ntawm cov qauv. Thaum xaiv lub tes tsho fiberglass, cov hauv qab no yuav tsum tau xav txog:
1.Strength and stiffness: Xaiv qhov tsim nyog lub zog thiab nruj raws li qhov tseeb engineering xav tau.
2.Txoj kab uas hla thiab ntev: Txiav txim siab qhov tsim nyog txoj kab uas hla thiab ntev ntawm lub tes tsho raws li qhov loj ntawm cov qauv yuav tsum tau ntxiv dag zog.
3.corrosion kuj: xyuas kom meej tias lub tes tsho fiberglass tuaj yeem tiv taus cov tshuaj nyob rau hauv ib puag ncig hauv qab dej thiab kev yaig ntawm cov dej hiav txwv.
II. underwater epoxy grout
Underwater epoxy grout yog cov khoom siv tshwj xeeb grouting, feem ntau yog tsim los ntawmepoxy cobthiab hardener. Nws muaj cov yam ntxwv hauv qab no:
1.water tsis kam: nws muaj dej zoo heev thiab tsis cuam tshuam los ntawm underwater ib puag ncig.
2.bonding: muaj peev xwm tsim kom muaj kev sib raug zoo nrog lub tes tsho fiberglass thiab txhim kho tag nrho lub zog ntawm cov qauv.
3.low viscosity: nrog tsawg viscosity, nws yog ib qho yooj yim rau ncuav thiab sau rau hauv cov txheej txheem underwater.
III. Epoxy sealant
Epoxy sealant yog siv rau kev sib khi lub tes tsho fiberglass nyob rau hauv underwater reinforcement project, uas tuaj yeem tiv thaiv dej infiltration thiab corrosion. Nws cov yam ntxwv yog raws li nram no:
1.water tsis kam: dej tsis kam, kev siv dej hauv qab ntev yuav tsis poob.
2.bonding: nws tuaj yeem tsim kev sib raug zoo nrog lub tes tsho iav fiber ntau thiab hauv qab dej epoxy grout los txhim kho kev ncaj ncees ntawm cov qauv tsim.
Txoj kev tsim kho:
1.Kev npaj: ntxuav qhov saum npoo ntawm cov txheej txheem reinforced, xyuas kom meej tias qhov chaw tsis muaj cov khib nyiab thiab cov pa phem.
2.Installation ntawm fiberglass tes tsho: kho lub tes tsho fiberglass ntawm cov qauv siv zog raws li tus qauv tsim.
3.Fill lub underwater epoxy grout: siv cov khoom tsim nyog los txhaj cov underwater epoxy grout rau hauv lub tes tsho fiberglass, sau tag nrho lub tes tsho.
4. sealing kev kho mob: siv epoxy sealer los kaw ob qhov kawg ntawm lub tes tsho fiberglass los tiv thaiv kev nkag mus ntawm noo noo.
Xaus:
Cov iav fiber ntau lub tes tsho, underwater epoxy grout thiab epoxy sealant yog cov khoom siv feem ntau siv hauv cov dej hauv qab qhov dej. Lawv ua lub luag haujlwm tseem ceeb hauv cov kabmob muaj peev xwm, kev ua haujlwm seismic thiab durability ntawm cov khoom siv ntxiv. Hauv kev xyaum, cov ntaub ntawv tsim nyog yuav tsum raug xaiv raws li cov kev xav tau tshwj xeeb thiab ua haujlwm raws li cov txheej txheem tsim kho kom ntseeg tau qhov zoo thiab kev ntseeg siab ntawm qhov kev txhawb nqa.
