Kev Siv Tshuab
1. Geotechnical engineering nrog GFRP thauj tog rau nkoj txhawb nqa tshuab
Qhov, txoj kab nqes thiab subway tej yaam num yuav koom nrog geotechnical anchoring, anchoring feem ntau siv high tensile zog steel li thauj tog rau nkoj rods, GFRP bar nyob rau hauv lub sij hawm ntev tsis zoo geological tej yam kev mob muaj zoo corrosion kuj, GFRP bar es tsis txhob steel thauj tog rau nkoj rods uas tsis xav tau kev kho corrosion. , siab tensile lub zog, lub teeb yuag thiab yooj yim rau kev tsim khoom, kev thauj mus los thiab kev teeb tsa zoo, tam sim no, GFRP bar tau nce siv los ua thauj tog rau nkoj rods rau tej yaam num geotechnical. Tam sim no, GFRP tuav tau siv ntau thiab ntau dua li cov pas nrig thauj tog rau nkoj hauv geotechnical engineering.
2. Tus kheej-inductive GFRP bar ntse saib xyuas tshuab
Fiber grating sensors muaj ntau yam tshwj xeeb zoo tshaj cov tsoos quab yuam sensors, xws li cov qauv yooj yim ntawm lub taub hau sensing, me me, lub teeb yuag, zoo repeatability, anti-electromagnetic cuam tshuam, siab rhiab heev, hloov pauv thiab muaj peev xwm muab cog rau hauv GFRP bar. nyob rau hauv cov txheej txheem ntau lawm. LU-VE GFRP Smart Bar yog ib qho kev sib txuas ntawm LU-VE GFRP tuav thiab fiber ntau grating sensors, nrog zoo durability, zoo heev deployment ciaj sia taus tus nqi thiab rhiab heev strain hloov cov yam ntxwv, haum rau civil engineering thiab lwm yam teb, raws li zoo raws li kev tsim kho thiab kev pab cuam nyob rau hauv hnyav. ib puag ncig tej yam kev mob.
3. Shield cuttable qhob qhov cuab lub zog technology
Txhawm rau txhawm rau thaiv cov dej nkag los yog cov av nyob rau hauv qhov kev txiav txim ntawm cov dej siab vim yog kev tshem tawm cov khoom siv dag zog hauv cov pob zeb hauv cov txheej txheem subway enclosure, sab nraum phab ntsa dej nres, cov neeg ua haujlwm yuav tsum sau qee cov av ntom ntom lossis txawm tias cov pob zeb dawb. . Kev ua haujlwm zoo li no yuav ua rau muaj kev siv zog ntawm cov neeg ua haujlwm thiab lub sijhawm voj voog ntawm kev khawb av hauv av. Qhov kev daws teeb meem yog siv GFRP bar tawb hloov steel tawb, uas tuaj yeem siv rau hauv cov txheej txheem ntawm cov txheej txheem subway kawg, tsis tsuas yog cov kabmob muaj peev xwm ua tau raws li qhov yuav tsum tau ua, tab sis kuj yog vim qhov tseeb tias GFRP bar pob zeb muaj cov qauv tsim. kom zoo dua uas nws tuaj yeem raug txiav hauv lub tshuab thaiv thaiv (TBMs) traversing lub enclosure, zoo heev tshem tawm cov kev xav tau ntawm cov neeg ua hauj lwm mus rau hauv thiab tawm ntawm lub chaw ua hauj lwm shafts nquag, uas yuav ua rau kom ceev ntawm kev tsim kho. thiab kev nyab xeeb.
4. GFRP bar ETC txoj kab kev siv tshuab
Cov kab ETC uas twb muaj lawm muaj nyob rau hauv qhov kev poob ntawm cov ntaub ntawv hla, thiab txawm tias rov txiav tawm, kev cuam tshuam ntawm cov neeg nyob sib ze, rov xa cov ntaub ntawv hloov pauv thiab kev hloov pauv tsis ua haujlwm, thiab lwm yam, kev siv cov khoom tsis sib nqus thiab tsis siv GFRP tuav es tsis txhob siv cov hlau hauv txoj kev. tuaj yeem qeeb qhov tshwm sim no.
5. GFRP bar nruam reinforced qhob pavement
Nruam ntxiv dag zog rau pob zeb pavement (CRCP) nrog kev tsav tsheb zoo, muaj peev xwm ua tau zoo, ruaj khov, yooj yim txij nkawm thiab lwm yam zoo, kev siv cov iav fiber ntau reinforcing tuav (GFRP) es tsis txhob siv cov hlau siv rau cov qauv pavement no, ob qho tib si kov yeej qhov tsis zoo ntawm kev yooj yim. corrosion ntawm steel, tab sis kuj yuav tswj tau qhov zoo ntawm kev txuas ntxiv dag zog pob zeb pavement, tab sis kuj txo cov kev ntxhov siab nyob rau hauv lub pavement qauv.
6. Lub caij nplooj zeeg thiab lub caij ntuj no GFRP bar anti-CI pob zeb siv tshuab
Vim muaj qhov tshwm sim ntawm txoj kev icing nyob rau lub caij ntuj no, ntsev de-icing yog ib txoj kev siv nyiaj ntau dua thiab siv tau zoo, thiab cov tshuaj chloride ions yog lub ntsiab culprits ntawm corrosion ntawm reinforcing steel nyob rau hauv reinforced pob zeb pavement. Kev siv cov tshuaj tiv thaiv zoo heev ntawm GFRP tuav es tsis txhob siv hlau, tuaj yeem ua rau lub neej ntawm pavement.
7. GFRP bar marine qhob qhov cuab lub zog siv tshuab
Chloride corrosion ntawm steel reinforcement yog qhov tseem ceeb tshaj plaws uas cuam tshuam rau kev ua haujlwm ntawm cov pob zeb ua vaj tse nyob rau hauv cov dej num offshore. Qhov loj-span girder-slab qauv feem ntau siv nyob rau hauv chaw nres nkoj terminals, vim nws tus kheej-yuag thiab lub loj load nws dais, yog raug rau loj dabtsi yog khoov lub sij hawm thiab shear rog nyob rau hauv lub ncua sij hawm ntawm lub longitudinal girder thiab ntawm kev txhawb nqa, uas nyob rau hauv tig ua kom tawg. Vim qhov kev ua ntawm cov dej hiav txwv, cov khoom siv hauv cheeb tsam no tuaj yeem corroded nyob rau hauv lub sij hawm luv luv, uas ua rau txo qis ntawm cov kabmob muaj peev xwm ntawm tag nrho cov qauv, uas cuam tshuam rau kev siv ntawm lub hiav txwv lossis txawm tias qhov tshwm sim ntawm kev nyab xeeb. .
Daim ntawv thov Scope: seawall, waterfront tsev qauv, aquaculture pas dej, dag reef, dej so qauv, floating dock
lwm.
8. Lwm cov kev siv tshwj xeeb ntawm GFRP tuav
(1) Anti-electromagnetic cuam tshuam tshwj xeeb daim ntawv thov
Tshav dav hlau thiab tub rog cov chaw tiv thaiv radar cuam tshuam cov cuab yeej, cov cuab yeej siv tub rog rhiab heev, cov phab ntsa pob zeb, tsev kho mob MRI cov cuab yeej, geomagnetic observatory, nuclear fusion vaj tse, tshav dav hlau hais kom dav, thiab lwm yam, tuaj yeem siv tsis siv steel tuav, tooj liab tuav, thiab lwm yam. GFRP tuav ua cov khoom siv ntxiv rau pob zeb.
(2) Sandwich phab ntsa vaj huam sib luag connectors
Lub precast sandwich insulated phab ntsa vaj huam sib luag yog tsim los ntawm ob qho tib si sab vaj huam sib luag thiab ib txheej insulating hauv nruab nrab. Cov qauv siv cov tshiab OP-SW300 iav fiber reinforced composite khoom (GFRP) connectors los ntawm lub thermal rwb thaiv tsev board los txuas ob qho tib si sab panels ua ke, ua rau lub thermal rwb thaiv tsev phab ntsa tag tshem tawm txias txuas hniav nyob rau hauv kev tsim kho. Cov khoom no tsis tsuas yog siv cov khoom siv hluav taws xob uas tsis yog thermal conductivity ntawm LU-VE GFRP tendons, tab sis kuj muab kev ua si tag nrho rau kev sib xyaw ua ke ntawm phab ntsa sandwich.
