Dab tsi yog lub luag haujlwm tseem ceeb ntawm hauv qab -rail puag daim hlau?
Lub luag haujlwm tseem ceeb ntawm hauv qab - cov phiaj xwm kev tsheb ciav hlau yog txhawm rau txhawm rau txhawm rau txhawm rau lub siab ntawm txoj hlua ntawm cov neeg pw tsaug zog thiab subgrade, zam kev puas tsuaj los ntawm kev ntxhov siab hauv zos ntau dhau. Nws tuaj yeem nqus cov kev vibrations thiab cuam tshuam lub zog tsim los ntawm lub tsheb ciav hlau ua haujlwm, txo cov suab nrov, thiab txhim kho ib puag ncig ib puag ncig. Kho tus khiav qhov siab los ntawm elastic deformation los xyuas kom meej khiav smoothness thiab txhim khu neeg nrog kev nplij siab. Nws tuaj yeem txo qhov hnav ntawm cov ntsia hlau thiab cov neeg pw tsaug zog, txuas ntxiv lub neej kev pabcuam tag nrho ntawm cov khoom siv. Nws tuaj yeem hloov mus rau qhov sib txawv geological tej yam kev mob, tiv nrog lub hauv paus kev daws teeb meem lossis nthuav dav, thiab tswj cov qauv kev ruaj ntseg.
Dab tsi yog cov khoom siv hauv qab -rail base plates?
Roj hmab puag daim hlau yog cov khoom siv feem ntau, nrog zoo elasticity thiab durability, thiab kev poob siab tseem ceeb thiab txo cov suab nrov. Plastic puag daim hlau muaj xws li polyethylene, polypropylene thiab lwm yam, nrog zoo heev corrosion kuj thiab rwb thaiv tsev, thiab yog lub teeb yuag thiab ib puag ncig tus phooj ywg. Cov hlau phaj hauv paus phaj muaj lub zog siab, tuaj yeem cuam tshuam zoo, haum rau hnyav- cov kab, thiab qee qhov siv cov txheej tshwj xeeb los txhim kho corrosion. Composite puag daim hlau sib xyaw ua ke zoo ntawm roj hmab, yas thiab hlau, nrog lub teeb yuag, siab zog, zoo poob siab thiab muaj zog ib puag ncig adaptability. Lub hauv paus phaj ntawm cov ntaub ntawv sib txawv yog siv los ua ke raws li txoj kab uas yuav tsum tau ua, xws li cov phaj sib xyaw ntawm cov roj hmab + stainless hlau daim hlau.
Dab tsi yog qhov ntsuas kev ua tau zoo ntawm hauv qab -rail base plates?
Static stiffness yog qhov taw qhia tseem ceeb. Cov tawv nqaij zoo li qub ntawm cov roj hmab hauv paus daim hlau feem ntau yog 60 ± 10kN / mm, uas yuav tsum tau hloov kho raws li kab yuav tsum tau ua. Qhov piv ntawm dynamic rau static stiffness yog tsawg dua los yog sib npaug rau 2.0 los xyuas kom meej tias lub hauv paus phaj muaj peev xwm tswj tau ruaj khov elastic kev kawm nyob rau hauv dynamic loads. Lub zog tev ntawm cov phaj sib xyaw yog ntau dua lossis sib npaug ntawm 4kN / m los tiv thaiv kev sib cais ntawm cov khoom sib txawv. Shore A hardness yog ntau dua los yog sib npaug rau 65 los xyuas kom meej lub zog txhawb nqa thiab hnav tsis kam ntawm lub hauv paus phaj. Lub rwb thaiv tsev tiv thaiv yog ＞ 5 × 10 ^ 6Ω kom tsis txhob luv luv Circuit Court thiab hloov mus rau cov kab hluav taws xob.
Dab tsi yog qhov kev tiv thaiv kev txhim kho rau hauv qab - cov phiaj xwm tsheb ciav hlau?
Ua ntej kev teeb tsa, xyuas seb lub hauv paus phaj puas muaj kab nrib pleb, deformation thiab lwm yam tsis xws luag los xyuas kom meej cov khoom tsim nyog. Ntsuas qhov ntsuas thiab ntsuas qib kom paub meej qhov tseeb ntawm txoj haujlwm ntawm lub hauv paus phaj, raws li cov qauv tsim. Lub hauv paus phaj yuav tsum tau ua raws li txoj kev tsheb ciav hlau thiab kev pw tsaug zog, tsis muaj kev cuam tshuam los yog inclination, kom ntseeg tau tias muaj zog sib xws. Tighten cov bolts cuam tshuam tom qab kev teeb tsa kom ntseeg tau tias lub hauv paus phaj yog ruaj khov, tsis muaj kev pheej hmoo ntawm kev xoob lossis hloov chaw. Tom qab kev teeb tsa, xyuas qhov kev sib tw khiav thiab ua kom zoo yog tias tsim nyog los xyuas kom meej lub tsheb ciav hlau khiav haujlwm.
Yuav ua li cas xaiv nyob rau hauv -rail puag daim hlau raws li kab hom?
High - txoj kev tsheb ciav hlau ceev yuav tsum xaiv siab - cov roj hmab hauv paus daim hlau lossis cov phaj sib xyaw ua ke, uas muaj kev poob siab zoo thiab txo cov suab nrov thiab txhim kho kev caij tsheb. Hnyav- kev tsheb ciav hlau yuav tsum siv siab - lub zog steel phaj puag daim hlau lossis siab- cov phaj sib xyaw ua ke, uas tuaj yeem tiv taus cov khoom loj thiab cuam tshuam. Kev tsheb ciav hlau hauv nroog ua qhov tseem ceeb rau cov roj hmab hauv paus daim hlau uas tsis muaj suab nrov los txo kev cuam tshuam rau cov neeg nyob ib puag ncig. Cov kab hluav taws xob yuav tsum xaiv cov yas hauv paus daim hlau los yog cov phaj sib xyaw nrog cov rwb thaiv tsev zoo heev kom tsis txhob muaj kev puas tsuaj hauv Circuit Court. Hauv cov cheeb tsam txias, cov ntaub ntawv hauv paus phaj nrog qhov ruaj khov qis- qhov kub thiab txias yuav tsum tau xaiv kom tsis txhob muaj qhov kub thiab txias thiab ua kom muaj kev nyab xeeb ntawm kev siv lub caij ntuj no.
