Dab tsi yog Cov Cheeb Tsam Tseem Ceeb ntawm Railway Tracks?
Jan 28, 2026
Lub ntsiab Cheebtsam ntawm ib tug Railway Track
Ib tug pa ballasted khiav muaj xya pawg ntawm cov Cheebtsam, txhua tus muaj ib txoj hauj lwm sib txawv. Kev nkag siab txog lawv pab cov neeg yuav khoom qhia txog txoj kev tsheb ciav hlau, fastenings thiab accessories rau ib txoj kab tshiab lossis ib qhov project upgrade.
| Cheebtsam | Muaj nuj nqi |
|---|---|
| Rails (steel rails) | Qhov chaw khiav uas coj lub log thiab nqa lub tsheb ciav hlau thauj khoom |
| Sleepers (cov) | Tso perpendicular rau cov ntsia hlau; tuav lawv ntawm qhov ntsuas qhov tseeb thiab muab kev txhawb nqa |
| Fastening system | Ruaj ntseg cov ntsia hlau rau cov pw tsaug zog; tswj kev ntsuas thiab tiv thaiv kev txav ntsug thiab sab nraud |
| Ballast | Crushed pob zeb txheej uas cushions pw tsaug zog, faib load rau subgrade thiab muab tso kua dej |
| Subgrade (kev tsim) | Compacted av puag uas nqa tag nrho cov qauv khiav |
| Rail pob qij txha | Ntses daim hlau thiab bolts uas txuas kev tsheb ciav hlau xaus mus rau hauv txoj kev tas mus li |
| Turnouts (switches) | Movable khiav seem uas cia tsheb ciav hlau hloov ntawm ib kab mus rau lwm qhov |
Rails
Txoj kev tsheb ciav hlau yog qhov tseem ceeb thauj khoom - nqa khoom. Nws yuav tsum ncaj thiab muaj tseeb, nrog rau hnav tawv tawv- tiv taus lub taub hau thiab lub vev xaib tawv thiab lub hauv paus. Rail seem yog tsim los ntawm qhov hnyav ib 'meter': lub teeb rails los ntawm 8 mus rau 30 kg / m, hnyav rails los ntawm 38 mus rau 60 kg / m, thiab crane rails xws li QU70 rau QU120. Lub ntsiab- kab rails feem ntau muab rau GB, UIC, AREMA lossis DIN cov ntaub ntawv hauv qib xws li U71Mn lossis sib npaug hnav- cov hlau tsis muaj zog.
Cov pw tsaug zog
Cov neeg pw tsaug zog hloov cov tsheb ciav hlau mus rau lub ballast thiab kho qhov ntsuas. Ntoo pw tsaug zog tseem siv rau cov kab thib ob thiab kev lag luam vim tias lawv yooj yim los tuav thiab muab ntuj elasticity; pob zeb pw tsaug zog yog tus qauv rau cov kab tseem ceeb vim tias lawv tuav qhov ntsuas zoo dua thiab kav ntev dua; steel sleepers yog siv rau kev siv tshwj xeeb. Hom pw tsaug zog txiav txim siab qhov system fastening: spikes thiab baseplates rau ntoo, elastic clip systems nrog cam khwb cia-hauv xub pwg los yog dowels rau pob zeb.
Fastening Systems
Lub fastening system yog qhov sib txuas ntawm kev tsheb ciav hlau thiab pw tsaug zog. Nws cov khoom yog clips, ncoo, insulators, xub pwg los yog dowels, thiab screws los yog bolts.
| Cheebtsam | Lub hom phiaj |
|---|---|
| Rail clips | Elastic fasteners uas siv clamping quab yuam rau cov tsheb ciav hlau ko taw |
| Rail pads | Cushion nruab nrab ntawm txoj kev tsheb ciav hlau thiab pw tsaug zog; damp kev co thiab txo qhov cuam tshuam |
| Rail insulators / gauge blocks | Kev cais hluav taws xob rau kev teeb tsa thiab ntsuas ntsuas |
| Rail anchors | Tiv thaiv longitudinal txav (creep) |
| Rail spikes | Kho cov ntsia hlau rau cov ntoo pw (dog spikes, ntsia hlau spikes) |
| Tie daim hlau / baseplates | Tshaj tawm cov khoom thauj thiab muab lub rooj tsav tsheb ruaj ntseg |
Ballast thiab Subgrade
Ballast yog ib txheej ntawm cov pob zeb crushed, feem ntau 25- 60 hli grading, uas cushions cov pw tsaug zog, tuav lawv nyob rau hauv qhov chaw, kis tus load tshaj subgrade thiab cia dej ntws tawm ntawm txoj kev. Lub subgrade yog lub compacted tsim hauv qab lub ballast; nws qhov zoo teev qhov ntev -lub sij hawm stability ntawm kab. Slab khiav hloov ballast nrog lub hauv paus pob zeb uas yuav tsum tau muaj kev saib xyuas tsawg, xws li cov kab ceev thiab qhov tunnels.
Yuav ua li cas ib tug Fastening System yog ntsia
Kev teeb tsa ua raws li tus qauv ua ntu zus ntawm cov pob zeb- pw tsaug zog: tso cov tsheb ciav hlau rau ntawm lub rooj zaum pw tsaug zog, tso cov ntsia hlau, ntxig cov insulators thiab ntsuas ntsuas, haum cov clips rau hauv lub xub pwg nyom los yog dowels, ces tsav los yog nias cov clips rau hauv qhov chaw nrog hydraulic lossis phau ntawv. Rau bolted fastenings lub bolts yog nruj rau qhov teev torque yog li cov roj hmab Cheebtsam yog compressed rau lub thickness tsim. Cov kauj ruam kawg yog ntsuas ntsuas thiab ntsuas qhov ntsuas ntawm qhov nruab.
Cov lus nug nquag
1. Dab tsi yog qhov tseem ceeb tshaj plaws ntawm txoj kev tsheb ciav hlau?
Txhua yam yuav tsum tau muaj, tab sis txoj kev tsheb ciav hlau thiab lub kaw lus fastening yog qhov tseem ceeb ntawm khub: lub tsheb ciav hlau nqa lub log load, thiab lub fastening ua kom nws raws nraim hauv txoj hauj lwm. Ib qho kev ua tsis tiav ntawm ob tog nres tsheb.
2. Vim li cas cov neeg pw tsaug zog tau muab tso rau ntawm txoj hlua?
Cov neeg pw tsaug zog khiav hla txoj kab khiav kom lawv tuaj yeem tuav ob txoj hlua ntawm qhov ntsuas kom raug thiab faib lub log loads rau sab hauv lub ballast. Qhov kev npaj no kuj tiv thaiv lub zog sab nraud los ntawm kev tsheb ciav hlau ntawm cov nkhaus.
3. Dab tsi yog qhov txawv ntawm ballasted thiab slab khiav?
Ballasted khiav nyob rau ntawm pob zeb crushed thiab yog pheej yig dua los tsim thiab kho. Slab taug kev siv lub hauv paus pob zeb txuas ntxiv, uas xav tau kev saib xyuas tsawg dua, siv sijhawm ntev dua thiab haum rau siab - kev khiav haujlwm ceev, tab sis raug nqi ntau dua thiab nyuaj rau kev kho dua tshiab.
4. Cov phaj ntses siv rau dab tsi?
Ntses daim hlau (cov tuav sib koom tes) clamp qhov kawg ntawm ob txoj hlua ua ke nrog ntses bolts. Lawv ua kom cov tsheb ciav hlau xaus ua ke vertically thiab tom qab kom cov log hla qhov sib koom ua ke. Ntawm cov kab tseem ceeb niaj hnub no, cov pob qij txha welded tau hloov cov ntses feem ntau -plated pob qij txha.
5. Kev xa tawm ua haujlwm li cas?
Lub turnout siv cov hniav hloov pauv thiab hla (qav) coj lub log ntawm ib txoj kev mus rau lwm qhov. Cov hniav yog txav los ntawm lub tshuab taw tes, thiab kev hla cia lub log flanges hla kev sib tshuam ntawm ob txoj hlua.
6. Qhov twg fastening yog siv rau high - kab ceev?
High- cov kab ceev siv cov txheej txheem elastic fastening ntawm cov pob zeb pw tsaug zog lossis slab khiav, nrog cov tsheb ciav hlau pads tuned rau kev vibration damping thiab tus ntiv taw siab -load clips uas tuav ntsuas qhov tseeb. Tag nrho cov kab ke yog hom - sim rau qhov tsim ceev thiab qag load ntawm kab.
