Fiberglass txhawb Polymer Bars
Cov lus qhia ntxaws ntxaws
Fiber ntau txhawb kev sib xyaw (FRP) hauv cov teeb meem kev ua haujlwm hauv zej zog thiab hauv qee cov kws tshaj lij kev ua lag luam, cov kws tshaj lij kev lag luam ntseeg tias nws daim ntawv thov yog xaiv. Nyob rau hauv lub subway shield txiav qhob ua qhob cov qauv yas thiab lwm thaj av txhawb, ntau dua thiab lees paub los ntawm cov kev tsim kho.
Khoom Qhia Txog Khoom
Nominal diameters ntawm 10mm rau 36mm. Pom zoo cov nominal diaminal rau gfrp cov kab yog 20mm, 22mm, 25mm, 25mm thiab 32mm.

Cov Lus Qhia: Lwm cov ntaub ntawv yuav tsum tau ua raws li cov kev cai tswj hwm JG / T40-20-2013 "khob fiber ntau ntxiv rau cov yas rau cov neeg txua khoom"
Kev siv tshuab
1. Geotechnical engineering nrog GFRP Thauj Tshuab
Qhov chaw, txoj kab nqes thiab kev thauj khoom hauv lub zog, GRRP Luj pas nrig rau geotechnical tej yaam num. Tam sim no, GFRP cov tuav tau siv ntau dua thiab ntau dua li cov pas nrig mus rau hauv cov pas nrig hauv nkoj hauv Geotechnical engineering.
2. Kev Coj Tus Kheej GFRP Bar Cov Tshuab Tshuaj Txawj Ntse
Kev sib cav sib ceg muaj kev sib haum xeeb muaj ntau cov qauv sib txawv ntawm cov qauv yooj yim thiab cov khoom siv hluav taws xob, cov peev txheej me me, cov peev xwm los tiv thaiv cov duab thiab cov muaj peev xwm los cog rau hauv GFRP bar hauv cov txheej txheem ntau lawm. Lu-ve gfrp ntse bar yog kev sib xyaw ntawm lu-ve sensors thiab lwm daim teb zoo, zoo li kev tsim kho thiab kev tsim kho nyob rau hauv cov xwm txheej hnyav.
3. Shield cuttable pob zeb ntxiv rau kev siv lub zog
Txhawm rau thaiv cov infiltration ntawm dej los yog av nyob rau hauv kev txiav txim ntawm cov qauv hlau, cov neeg ua haujlwm yuav tsum sau ib co av tuab lossis yooj yim. Cov kev ua haujlwm no undoubtedly nce kev siv dag zog ntawm cov neeg ua haujlwm thiab lub sijhawm voj voog ntawm qhov chaw khawb av khawb. Txoj kev daws teeb meem yog siv GFR lub tawb es tsis txhob siv rau hauv cov ntaub ntawv thaiv, tab sis nws tuaj yeem ua kom cov neeg ua haujlwm tau ua tiav, uas tuaj yeem nrawm nrawm ntawm kev tsim kho thiab kev nyab xeeb.
4. GFRP Bar thiab lwm yam kab kev thov tshuab
Cov kab ke uas twb muaj lawm nyob rau hauv cov lus tsis muaj kev cuam tshuam, thiab tsis sib nqus GFR.
5. GFRP Bar Nruam Cov Chaw Ua Haujlwm
Nrawg txuas ntxiv cov tuam txhab sib tsoo (CRCP) nrog rau kev txhawb nqa ntawm cov hlau uas yooj yim, tab sis kuj tau txo qis kev ntxhov siab ntawm cov qauv kev tuag.
6. Lub caij nplooj zeeg thiab lub caij ntuj no GFRP Bar tawm tsam tshuab ua khoom
Vim yog cov kev tshwm sim ib txwm muaj ntawm txoj kev icing hauv lub caij ntuj no, ntsev de-icing yog ib qho kev pheej yig ntawm corrosion ntawm kev txhawb nqa kev txhawb nqa cov hlau. Kev siv cov tshuaj tiv thaiv corrosion zoo heev ntawm GFRP tuav hloov hlau, tuaj yeem nce lub neej ntawm txoj kev pavement.
7. GFRP Bar Tubrog nkoj uas tau txhawb cov tshuab
Chloride corrosion ntawm cov hlau txhawb yog qhov tseem ceeb tshaj plaws cuam tshuam rau lub durabiled ua vaj tse hauv pob zeb hauv ntug dej hiav txwv. Qhov loj-ntiav girder-slab qauv feem ntau siv nyob rau hauv cov chaw nres tsheb loj, vim nws tus kheej hnyav, yog qhov kev txhawb nqa loj, uas nyob rau hauv lem ua rau tawg. Vim tias qhov kev txiav txim ntawm Seasater, cov qauv siv hauv zej zog tau corroded nyob rau hauv lub sij hawm luv luv ntawm lub wharf lossis txawm tias muaj kev nyab xeeb ntawm kev nyab xeeb ntawm kev nyab xeeb.
Daim Ntawv Thov Cov Ntaub Ntawv: Seawall, Lub Tsev Dej Ua Si, Dej Aquarorure, Dej tawg, ntab dock
lwm yam.
8. Lwm cov ntawv thov tshwj xeeb ntawm GFRP tuav
(1) Kev cuam tshuam los tiv thaiv hluav taws xob tshwj xeeb
Tshav Dav Hlau thiab Tub Rog Cov Chaw Cog Lus Los Tiv Thaiv cov cuab yeej, cov cuab yeej siv tub rog tsis sib xws, thiab lwm yam GFRP tuav raws li cov khoom siv txhawb rau cov pob zeb.
(2) Sandwich Phab Ntsa Vaj Huam Sib Luag Txuas Txuas
Vaj huam sib luag precast facwich insulated phab ntsa vaj huam sib luag yog tsim ntawm ob lub tog qhob tog vaj huam sib luag thiab txheej txheej insulating thiab txheej txheem insulating nyob rau hauv nruab nrab. Tus qauv adopts cov tshiab tshaj tawm tshiab OP-Sw300 iav fiber ntau cov khoom siv sib xyaw ua ke, ua kom cov thermal rwb thaiv tsev ua ke tshem tawm cov choj tus choj txias hauv kev tsim kho. Cov khoom no tsis yog siv rau qhov tsis-thermal conductivity ntawm lu-ve gfrp tendons, tab sis kuj muab tag nrho cov kev ua haujlwm ntawm phab ntsa xuab zeb.
