Anchoring Technology thiab Installation Stability Guarantee rau Rail Spikes
Dab tsi yog cov kauj ruam tseem ceeb ntawm cov txheej txheem spike sulfur anchoring?
Cov kauj ruam tseem ceeb ntawm cov txheej txheem spike sulfur anchoring muaj xws li plaub qhov txuas: drilling thiab lub qhov tu, tus neeg sawv cev kub hnyiab, tus neeg saib xyuas kev sib tsoo thiab ntxig spikes. Ua ntej, nws yog ib qho tsim nyog los laum qhov ntawm lub sleeper. Lub qhov taub thiab qhov tob yuav tsum sib npaug ntawm qhov loj me. Tom qab drilling, siab - cua siab yog siv los tshem tawm cov plua plav thiab cov khib nyiab hauv lub qhov kom tsis txhob muaj kev cuam tshuam rau kev sib xyaw ua ke ntawm tus neeg sawv cev thiab cov phab ntsa ntawm lub qhov. Qhov thib ob kauj ruam yog boil tus sulfur anchoring tus neeg sawv cev. Tus neeg sawv cev anchoring yog tov nrog sulfur, cement, xuab zeb thiab paraffin hauv kev faib ua feem. Qhov kub npau npau yog tswj ntawm 140-160 degree, thiab nws yog stirred tusyees kom txog thaum nws yog kua. Tom qab ntawd tus neeg sawv cev molten anchoring yog sai sai rau hauv lub qhov, thiab lub qhov siab ntawm lub ncuav yuav tsum siab me ntsis siab dua lub qhov ncauj qhov ncauj kom tsis txhob muaj qhov khoob tom qab tus neeg sawv cev anchoring txias thiab shrinks. Thaum kawg, ntxig qhov ntsia hlau loj hauv lub sijhawm, kho qhov ntsug ntawm qhov ntsia hlau loj, thiab tom qab tus neeg sawv cev anchoring txias thiab solidifies, tus ntsia hlau loj tuaj yeem ruaj khov rau ntawm tus neeg pw tsaug zog.
Dab tsi yog qhov zoo ntawm cov tshuaj anchoring piv nrog sulfur anchoring?
Thawj qhov zoo ntawm cov tshuaj anchoring piv nrog sulfur anchoring yog siab dua anchoring zog. Cov tshuaj anchoring tus neeg sawv cev yog cov khoom siv polymer. Tom qab kho, lub zog sib txuas nrog cov ntsia hlau loj thiab cov pob zeb qhov phab ntsa tuaj yeem ncav cuag ntau dua 30MPa, uas yog siab dua li cov neeg sawv cev ntawm cov sulfur anchoring. Qhov thib ob kom zoo dua yog muaj zog adaptability rau kev tsim kho ib puag ncig. Cov tshuaj anchoring tus neeg sawv cev tuaj yeem tsim nyob rau hauv qhov kub ntawm -10℃txog 40 degree, thaum cov tshuaj sulfur anchoring agent kho maj mam nyob rau hauv qis- qhov kub thiab txias thiab yooj yim rau soften nyob rau hauv high{11}}kub ib puag ncig. Qhov thib peb zoo dua yog kev tsim kho yooj yim dua. Cov tshuaj anchoring tus neeg sawv cev yog cov khoom ntim ua ntej -, uas tsis xav tau ntawm qhov chaw boiling, thiab tuaj yeem txhaj rau hauv lub qhov tom qab sib xyaw ua ke, ua rau lub sijhawm siv sijhawm luv. Tsis tas li ntawd, cov tshuaj anchoring tus neeg sawv cev muaj kev tiv thaiv corrosion zoo dua, kev ua haujlwm ruaj khov nyob rau hauv qhov chaw ntub thiab corrosive, thiab tsis muaj dej noo rov qab los yog tawg ntawm tus neeg sawv cev sulfur anchoring.
Hom pw tsaug zog twg yog qhov ua ntej -embedded anchoring txheej txheem haum rau?
Cov txheej txheem ua ntej -embedded anchoring yog tsim nyog rau precast qhob pw tsaug zog. Lub pre-embedding ntawm spikes yog ua tiav synchronously thaum lub sij hawm tsim cov sleepers, uas yog ib lub Hoobkas - raws li txoj kev anchoring. Cov txheej txheem no yuav tsum tau muab qhov tseeb ntawm qhov chaw nyob rau hauv cov pwm pw tsaug zog kom ntseeg tau tias qhov ntsug thiab qhov sib txawv ntawm cov spikes ua tau raws li cov qauv tsim, thiab tom qab ntawd cov pob zeb yog nchuav kom khov kho cov spikes nrog cov neeg pw tsaug zog. Qhov zoo ntawm cov txheej txheem ua ntej -embedded anchoring yog qhov tseeb qhov chaw siab. Lub verticality sib txawv ntawm cov ntsia hlau loj tuaj yeem tswj tau nyob rau hauv ± 1 degree, uas yog qhov zoo tshaj rau ntawm - txheej txheem anchoring site. Cov txheej txheem no tsim nyog rau cov hom kev taug qab uas muaj qhov yuav tsum tau ua kom raug siab, xws li siab - kev tsheb ciav hlau ceev tsis muaj kev tsheb ciav hlau thiab tsheb ciav hlau hauv nroog. Rau cam khwb cia-hauv- qhov chaw pw pob zeb lossis cov qub pw tsaug zog kho dua tshiab, cov txheej txheem ua ntej- embedded anchoring yog tsis muaj feem xyuam, thiab sulfur anchoring lossis tshuaj anchoring txheej txheem yuav tsum tau xaiv.
Dab tsi yog qhov yuav tsum tau rau lub verticality sib txawv ntawm spike installation?
Lub verticality sib txawv ntawm spike installation yuav tsum nruj me ntsis tswj nyob rau hauv ± 2 degree. Qhov kev xav tau no yog txhawm rau ua kom muaj kev ntxhov siab tsis sib xws ntawm qhov dav thiab tsis txhob muaj kev ntxhov siab hauv zos vim muaj kev xav. Thaum lub verticality sib txawv ntau tshaj 2 degree, lub zog xa mus kev taw qhia ntawm lub spike yuav hloov thaum nws bears lub tsheb ciav hlau load, thiab lub bonding nto ntawm spikes thiab lub anchoring tus neeg saib xyuas yog nquag muaj kev nyuaj siab concentration. Nyob rau hauv lub sijhawm ntev - lub sijhawm thauj khoom, tus neeg sawv cev thauj khoom yuav tawg thiab qhov dav yuav xoob. Thaum lub sij hawm tsim kho, yuav tsum tau siv ib theem lossis tshwj xeeb qhov cuab yeej los pab txhim kho. Tom qab ntxig cov ntsia hlau loj, qhov verticality yuav tsum tau kuaj xyuas lub sijhawm, thiab qhov sib txawv yuav tsum tau kho tam sim yog pom. Rau ua ntej -embedded anchored spikes, nws yog ib qho tsim nyog yuav tsum nruj me ntsis tswj cov pwm qhov chaw raug thaum lub sij hawm pw tsaug zog ntau lawm los xyuas kom meej qhov verticality ntawm spikes los ntawm qhov chaw. Kev tswj xyuas meej ntawm kev sib tw ntsug yog tus yuam sij kom ntseeg tau nws qhov kev pabcuam ntev -lub sijhawm ruaj khov.
Yuav ua li cas los txhim kho qhov rub- tawm ntawm kev tiv thaiv ntawm spikes tom qab kev teeb tsa?
Thawj qhov kev ntsuas los txhim kho qhov rub- tawm ntawm qhov kev tawm tsam ntawm kev teeb tsa spike yog txhawm rau txhim kho cov txheej txheem anchoring. Sulfur anchoring yuav tsum nruj me ntsis tswj qhov kub kub thiab qhov sib piv ntawm tus neeg sawv cev anchoring kom paub meej tias tus neeg sawv cev anchoring yog sib xyaw nrog lub qhov phab ntsa; chemical anchoring yuav tsum xaiv high-tus neeg saib xyuas zoo thiab xyuas kom meej tias tus neeg sawv cev thauj khoom nyob hauv lub qhov tsis muaj npuas thiab qhov khoob. Qhov kev ntsuas thib ob yog txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau nws, nws, qhov kev txiav txim siab, nws yog qhov tsim nyog yuav tsum tau ua tib zoo saib xyuas cov yub. Qhov tob ntawm qhov embedding qhov tob, qhov loj dua qhov chaw sib cuag ntawm tus neeg saib xyuas thiab cov ntsia hlau loj, thiab qhov muaj zog dua qhov rub - tawm tsis kam. Feem ntau, qhov embedding qhov tob ntawm qhov ntsia hlau loj yog tsis tsawg tshaj li 100 hli. Qhov thib peb ntsuas yog xaiv ribbed spikes. Cov tav ntawm qhov ntsia hlau loj tuaj yeem txhim kho qhov kev sib cuam tshuam ntawm cov neeg kho tshuab nrog tus neeg sawv cev anchoring. Piv nrog cov pob txha du, qhov rub tawm - tawm tsam tuaj yeem nce ntau dua 20%. Tsis tas li ntawd, hooks lossis lub taub hau nthuav dav tuaj yeem teem rau hauv qab ntawm qhov ntsia hlau loj kom ntxiv dag zog rau cov neeg kho tshuab anchoring nyhuv. Los ntawm cov kev ntsuas dav dav, qhov rub- tawm ntawm qhov kev tawm tsam ntawm qhov ntsia hlau loj tuaj yeem nce 30%-50% kom ua tau raws li qhov xav tau ntawm cov kab sib txawv.
