Kev paub txog New Anchoring Technologies rau Railway Spikes thiab txhim kho kev tsim kho kom zoo
Dab tsi yog qhov zoo ntawm inorganic tshuaj anchoring tshuab piv nrog cov tshuaj sulfur anchoring?
Inorganic chemical anchoring agents yog tsim los ntawm inorganic cov ntaub ntawv xws li silicates thiab aluminates, tsis muaj volatile teeb meem tshuaj, zoo ib puag ncig kev ua tau zoo, thiab ua tau raws li ib puag ncig yuav tsum tau ntawm kev tsheb ciav hlau hauv nroog. Kev tsim kho tsis tas yuav tsum muaj cua sov, zam qhov hluav taws kub thiab tawg txaus ntshai ntawm cov sulfur anchoring, txo kev tsim kev nyab xeeb kev nyab xeeb thiab txhim kho qhov chaw ua haujlwm. Lub curing ceev yog ceev; Nws tuaj yeem ncav cuag 80% ntawm cov qauv tsim lub zog hauv 2 teev ntawm chav tsev kub thiab kho tag nrho hauv 24 teev, thaum cov tshuaj sulfur anchoring yuav siv sijhawm ntau dua 24 teev, txhim kho kev tsim kho zoo heev. Lub zog anchoring yog siab, nrog rau rub- tawm qhov kev tawm tsam ntawm Ntau dua lossis sib npaug ntawm 80KN, tshaj li 60KN ntawm cov tshuaj sulfur anchoring, yoog raws li cov kev xav tau ntawm hnyav- cov kab. Nws muaj kev laus ua haujlwm zoo, tswj kev ua haujlwm ruaj khov nyob rau hauv ib puag ncig ntawm -40℃~ 60 degree, nrog rau kev pab cuam lub neej ntawm ntau tshaj 20 xyoo, piv nrog txog 10 xyoo rau cov tshuaj sulfur anchoring.
Dab tsi yog qhov muaj feem cuam tshuam thiab cov yam ntxwv tseem ceeb ntawm rail spike mechanical anchoring technology?
Cov cuab yeej siv thev naus laus zis kho kev tsheb ciav hlau los ntawm lub tes tsho nthuav dav lossis cov qauv xov, tsis tas yuav tsum muaj tus neeg sawv cev rau kev teeb tsa, kev tsim kho ceev ceev, thiab lub sijhawm teeb tsa ntawm ib qho kev sib tw tsheb ciav hlau tsawg dua lossis sib npaug li 5 feeb, tsim rau cov haujlwm uas muaj lub sijhawm siv nruj xws li kev kho thaum muaj xwm ceev thiab kho dua tshiab. Nws yog sib xws nrog ntau hom kev pw tsaug zog xws li pob zeb pw tsaug zog thiab steel sleepers, tsis muaj qhov tshwj xeeb anchoring qhov xav tau, thiab drilling thiab kev teeb tsa tuaj yeem nqa tawm ntawm cov pw tsaug zog uas twb muaj lawm, muaj zog yooj. Nws muaj zog detachability; Tom qab cov kab nrib pleb puas lawm, nws tuaj yeem ncaj qha disassembled thiab hloov yam tsis muaj kev puas tsuaj rau tus neeg pw tsaug zog. Cov txheej txheem anchoring ib txwm xav kom ua rau cov neeg pw tsaug zog los hloov txoj kev tsheb ciav hlau, ua rau cov nqi kho mob siab. Lub rub- tawm tsis kam yog ruaj khov ntawm 70-90KN, ua tau raws li cov kev xav tau ntawm cov kab zoo tib yam thiab kev tsheb ciav hlau hauv nroog; hnyav-haul kab yuav tsum tau sib phim nrog lub tes tsho muaj zog. Kev tsim kho tsis cuam tshuam los ntawm qhov kub thiab txias, thiab tuaj yeem nqa tawm ib txwm ntawm -20℃~ 40 degree, daws qhov teeb meem ntawm kev tsim kho nyuaj ntawm sulfur anchoring nyob rau lub caij ntuj no.
Dab tsi yog cov kauj ruam tseem ceeb hauv kev tsim kho cov thev naus laus zis tshiab?
Thawj kauj ruam ntawm inorganic tshuaj anchoring siv yog drilling thiab lub qhov ntxuav. Ib qho kev xyaum tshwj xeeb yog siv rau qhov drilling, lub qhov taub yog 4-6mm loj dua li txoj kab uas hla ntawm txoj kab nruab nrab, thiab cov cua compressed yog siv los tshuab ntxuav cov plua plav thaum lub qhov ntxuav kom huv si thiab qhuav. Cov kauj ruam thib ob yog txhaj cov tshuaj tiv thaiv kab mob: sib tov cov khoom A thiab B hauv kev faib ua feem thiab txhaj rau hauv lub qhov, qhov ntim ntim yog 80% ntawm lub qhov ntim kom tsis txhob dhau ntawm tus neeg saib xyuas anchoring. Qhov thib peb kauj ruam yog inserting lub rail spikes: lub rail spike yuav tsum tau muab tso rau ntsug, qhov tob qhov tob raws li tus tsim yuav tsum tau, thiab tig lub rail spike 2-3 zaug kom ntseeg tau tias tag nrho ua ke nrog tus neeg sawv cev anchoring. Kauj ruam plaub yog kho thiab tu: kho nyob rau hauv chav tsev kub rau 24 teev, thiab tsis txhob cuam tshuam lub rail spikes nyob rau lub sij hawm no; Cov kab hnyav hnyav yuav tsum tau kho rau 48 teev. Mechanical anchoring kev tsim kho yuav tsum tau drilling ua ntej, ces ntxig lub tes tsho expansion rau hauv lub qhov, thiab ces screwing nyob rau hauv lub rail spikes, uas ua rau lub tes tsho nthuav dav los ntawm nruj nreem ntsia hlau ntsia hlau loj thiab sib txuas nrog lub qhov phab ntsa.
Yuav ua li cas tswj kev tsim kho kom zoo ntawm cov cuab yeej tshiab anchoring?
Rau cov tshuaj inorganic anchoring, qhov feem ntawm tus neeg sawv cev anchoring yuav tsum nruj me ntsis tswj. Cov Cheebtsam A thiab B tau sib xyaw ua ke raws li cov lus qhia, thiab lub sijhawm nplawm yog ntau dua lossis sib npaug li 3 feeb kom ntseeg tau tias sib xyaw ua ke, zam lub zog tsis txaus vim qhov tsis raug. Qhov tob qhov tob thiab lub qhov taub yuav tsum ua tau raws li cov qauv tsim, qhov sib txawv qhov tob yog tsawg dua lossis sib npaug li ± 5mm, thiab lub qhov taub qhov sib txawv yog tsawg dua lossis sib npaug li ± 0.5mm, txwv tsis pub cov nyhuv anchoring yuav raug cuam tshuam. Tom qab muab cov ntsia hlau ntsia hlau loj, ib theem yuav tsum tau siv los kho qhov ntsug, nrog qhov sib txawv ntawm Tsawg dua lossis sib npaug li 1℃kom ntseeg tau tias lub zog sib xws thiab tsis txhob txo qis rub - tawm qhov tsis kam vim kev xav. Rau cov tshuab anchoring, lub tes tsho sib txuam nrog cov lus qhia tshwj xeeb yuav tsum raug xaiv, thiab qhov sib txawv ntawm lub tes tsho sab nraud thiab lub qhov taub yog tsawg dua lossis sib npaug li 0.3mm kom ntseeg tau tias cov nyhuv nthuav. Tom qab kev tsim kho, rub- tawm qhov kev tawm tsam yuav tsum tau kuaj thiab kuaj raws li qhov sib faib: Ntau dua lossis sib npaug rau 80KN rau cov tshuaj inorganic anchoring thiab Ntau dua lossis sib npaug rau 70KN rau kev siv tshuab anchoring; cov qauv tsis tsim nyog yuav tsum tau rov ua dua.
Dab tsi yog daim ntawv thov cuam tshuam ntawm cov thev naus laus zis tshiab hauv ntau hom kab?
Inorganic chemical anchoring technology tau siv dav hauv kev tsheb ciav hlau hauv nroog, xws li Beijing Metro thiab Shanghai Metro. Kev tsim kho kev ua tau zoo tau raug txhim kho los ntawm 30%, qhov zoo ntawm qhov chaw nres tsheb yog ruaj khov, thiab tsis muaj kev tsheb ciav hlau tawg tau tshwm sim. Cov cuab yeej siv thev naus laus zis yog tsim rau kev txhim kho kev tsheb ciav hlau thaum muaj xwm txheej ceev, xws li cov xwm txheej xwm txheej ceev xws li kab tawg thiab kev puas tsuaj ntawm kev tsheb ciav hlau, uas tuaj yeem kho cov kab tsheb sai sai thiab txo lub sijhawm kho xwm txheej ceev. Hnyav- cov kab nqa tau txais cov tshuaj inorganic tshuaj anchoring cov neeg ua haujlwm nrog kev rub- tawm ntawm kev tiv thaiv ntau dua lossis sib npaug li 90KN, uas tuaj yeem tiv taus qhov cuam tshuam loj thiab muaj txiaj ntsig zoo hauv cov ceg kab ntawm Datong-Qinhuangdao Railway. Cov cuab yeej siv thev naus laus zis yog siv nyob rau hauv cov pa railways, txo cov nqi txij nkawm los ntawm 40% thiab txhim kho kev tsheb ciav hlau hloov pauv kev ua haujlwm tau zoo los ntawm 5 zaug, txo cov kab thaiv lub sijhawm. Cov cheeb tsam Alpine txais yuav tsawg-kub inorganic chemical anchoring agents, uas tuaj yeem kho tau ib txwm nyob ntawm -20 degree, daws qhov teeb meem ntawm lub caij ntuj no kev tsim kho ntawm cov tshuaj sulfur anchoring, thiab tus nqi tsim nyog tau nce mus txog 99% tom qab thov.
