1 Lub peev txheej tseem ceeb thiab kev ua tau zoo ntawm fiber ntau rau qhov
Fiber ntau rau qhov qhob ua cov qhob muaj peb cov ntsiab lus zoo rau subway engineering. Nws muaj cov hloov kho cov khoom siv cov khoom siv tshuab: Fiber rau qhov chaw sib tw, thaum tseem muaj peev xwm hla dhau los ntawm kev txhawb nqa lub zog ntawm cov kev txhawb nqa hauv cov khoom muag lossis pob zeb ua pob zeb. Durability yog cov muaj peev xwm txhim kho: fiber ntau rau qhov ua rau cov khoom thiab cov neeg sawv cev rau cov yas, thaiv cov neeg sawv cev rau cov khoom siv hauv av. Kev tsim kho thiab kev nyab xeeb yog ua ib txhij ua ke: fiber ntau rau cov khoom siv rebar uas tsis muaj zog, thiab kev txhim kho cov txheej txheem uas tsis muaj zog, thiab kev txhim kho kev nyab xeeb thaum lub sijhawm kev tsim kho thiab kev ua haujlwm.
2 Qhia Kev Tshawb Xyuas Kev Tshawb Fawb rau Fiber Ntau Rau Qhov
Kev xaiv xaiv yuav tsum nkag siab txog qhov chaw nyob thiab cov kev mob geological. Mainstream fiber ntau rau qhov sib faib ua peb hom: cov milled hom kev sib tw, muab cov qauv zoo nkauj thiab cov qauv kev txhawb nqa zoo heev uas raug rau cov khoom siv hluav taws xob zoo. Cov hlau {{2} huted hom, feem ntau xaus {} hooked, muaj lub zog tsim txiaj ntsig zoo thiab lub zog siab tshaj; Qhov kawg hooks txhim kho Anchorage, muab tus nqi {{}}} kev daws teeb meem uas muaj kev ntxhov siab uas cuam tshuam. Lub txiv ntseej - extracted hom muaj cov nqi ntau lawm tab sis me ntsis qis dua kev ruaj khov; Nws raug nquahu tsuas yog rau kev txhawb nqa ib ntus lossis cov txheej txheem ib ntus thiab yuav tsum tsis txhob siv nyob rau hauv lub ntsiab load {{}} cov kabmob.
3 Cov Ntsiab Lus Tseem Ceeb Hauv Paus Txoj Cai
Cov nam piv yog ib qho kev sib cuam tshuam tseem ceeb cuam tshuam rau cov nyhuv txhim kho thiab siv kev ua haujlwm. Rau subway qhov engineering, nws raug nquahu kom tswj cov nam ntawm cov kev sib piv nyob rau hauv thaj tsam ntawm 50 - 70. Feem ntau siv fiber ntau rau qhov ntev ntev yog 25-35mm nrog diameters ntawm 0.5-0.7mm. Qhov ntau no ua kom muaj kev faib tawm cov kev faib tshuaj fiber ntau thaum lub rooj sib tham tsim cov cai. Cov fiber ntau rau qhov ntim ntim cov fertact hwm ncaj qha cuam tshuam cov qhob qheb cov nyhuv txhim kho. Txog hauv ob sab hauv thiab txhawb nqa qauv, kev them nyiaj ntau npaum li cas ntawm 1.0% -1.5% yog pom zoo. Qhov kev faib ua feem no tuaj yeem nce cov qhob nrib pleb tsis kam thiab flexural tensile lub zog los ntawm 30% -50% ntsuas kev ua haujlwm thiab kev lag luam. Lub tensile lub zog ntawm fiber ntau rau cov chaw yuav tsum tsis pub tsawg dua 600mpa kom paub meej tias feem ntau siv C50
4 Tag nrho - txheej txheem kev tswj hwm zoo
Kev tswj kom zoo yuav tsum tau npog tag nrho cov txheej txheem los ntawm Raw cov khoom xaiv, kev tsim qauv sib tov, tsim khoom, los kho. Rau cov ntaub ntawv raw, Pen · O 52.5 Portland Maas yuav tsum raug xaiv, nrog rau cov qhab nia sib txuas lus tsis tu ncua ntawm 2,8- 2.9. Ib qho Composite admixture ntawm silica fumica thiab hmoov av yuav tsum tau siv los txhim kho qhov ntom thiab kev ua haujlwm. Sib tov kev tsim qauv yuav tsum yog hais cov yam ntxwv ntawm kev siv tes. Rau C60 fiber ntau rau qhov ua vaj tse nyob, lub zog tsim tau muaj zog dua 57.5mpa, cov dej-rau-binder recio yuav tsum tau tswj hwm tsis pub dhau 180 ± 20mm.
Cov txheej txheem ntau lawm yuav tsum ua kom cov kev faib tawm cov fiber ntau. Txais yuav cov kev pub mis ua ntu zus ntawm kev sib xyaw qhuav ua ntej ua raws li cov xuab zeb sib xyaw ntub: Ua ntej no sib tov rau qhov rau 10-15 vib nas this, tom qab ntawd ntxiv lwm cov ntaub ntawv ua ntu zus. Lub sijhawm sib xyaw yuav tsum tau txuas ntxiv mus rau 170-200 vib nas this kom paub meej fiber ntau dispersion thiab ua kom tiav txheej los ntawm cov cement muab tshuaj txhuam. Nraws saib xyuas cov ntsiab lus noo noo ntawm cov xuab zeb, kuaj xyuas txhua txhua 100 zaus thaum los nag los ua kom muaj kev sib xyaw kom zoo ib yam nkaus.
Cov kev ntsuas tshwj xeeb yog xav tau rau cov kev tsim kho thiab kho theem. Qhov hauv ob sab hauv yuav tsum siv fawm kib ncuav, nrog txhua txheej thickness tswj ntawm 300-500mm. Siv cov cibrators spaced tsis pub ntau tshaj 400mm sib nrug, nrog lub sijhawm ua co ntawm 20-30 vib kab ntawm 20-30 vib kab ntawv, saib xyuas kom tsis txhob sib cuag nrog cov fiber ntau rau cov fiber ntau. Ua ntej kev teeb tsa thawj zaug, nthuav tawm cov fiber ntau rau qhov yuav tsum tau nias rau hauv cov pob zeb. Kev ntxuav dej noo yuav tsum pib nyob rau hauv 12 teev tom qab pouring ua tiav thiab nyob ntev rau tsis muaj tsawg tshaj li 14 hnub. Yog tias qhov cua yog cov neeg pluag, kev kho cov tebchaw yuav siv tau ua lwm txoj hauv kev kho dej.
5 Cov Qauv, Specifications, thiab Kev Ua Dua Tshiab
Daim ntawv thov ntawm cov fiber ntau rau qhov ua vaj tse nyob yuav tsum ua rau cov kev siv fiber ntau ntxiv thiab cov lej rau kev txais txiaj ntsig zoo ntawm cov tsheb ciav hlau hauv nroog loj. Kaw - voj voog kev tswj hwm kev tswj hwm npog kev tsim khoom, kev thauj mus los, thiab kev txais yuav tsum tau tsim. Kuaj cov swb thiab cov ris tsho ntawm cov fiber ntau rau cov faib faib rau txhua pob ua ntej tawm hauv lub hoobkas. Kev thauj mus los ntawm kev thauj mus los tsis pub dhau 1.5 teev. Coj cov hnoos qeev ntawm -} chaw raws li cov chaw tau teev tseg los ua cov hnoos qeev. Tom qab muaj kab ua tiav, ua ultrasonic ceev kev xeem thiab tawg qhov dav soj ntsuam.
Los ntawm embedding saib xyuas cov sensors hauv cov chaw tseem ceeb, cov kev pabcuam ntawm cov qauv tuaj yeem nkag tau hauv tiag- lub sij hawm. Tsis tu ncua sau thiab tshawb xyuas cov ntaub ntawv lub zog thiab kho cov tshuaj kho kom zoo, kom hloov kho kom zoo rau cov ntawv thov ua kom zoo ntawm cov fiber ntau rau cov pob zeb ua kom zoo. Qhov no ua cov txheej txheem tiv thaiv ntawm lub zog siab, muaj kev kub ntxhov rau kev ua haujlwm subway, kom muaj kev nyab xeeb ntev thiab ruaj khov ntawm cov kab subway.
Customization & hais kev pab: Peb txhawb kev cai customized. Thaum ua tiav ntawm cov kev qhia tshwj xeeb, peb ua kom cov ncauj lus kom ntxaws ntxiv, muaj lub ntsej muag ntshiab, thiab hais tawm, ua tiav cov qauv nqi. Txog kev yuav khoom lossis ntev -} Lub hom phiaj sib koom tes yuav cov cai Tom qab cog lus kos npe, kev tsim khoom yog qhov nrawm nrawm. Txhua cov khoom lag luam yeb ntau cov puag ncig ntawm kev soj ntsuam zoo ua ntej cov khoom siv kom ua tau zoo ua ntej lub siab ua tau zoo nrog "ua nyob rau hauv Suav teb."
