Isitimela Sesitimela Sensimbi Esijwayelekile se-GB Intengo Enzima Yefektri Isitimela Sensimbi Esiqinile Futhi Esihlala Isikhathi Eside Esifanele Ukwakhiwa Njllnjalonjalo
Ngomqondo othile,imikhiqizo yesitimela ethengiswa ngobuningiintuthuko nayo ingumlando wentuthuko yezitimela. Ngaphandle kwentuthuko yobuchwepheshe bezitimela, ubuchwepheshe bezitimela obusebenza kanzima nobushesha kakhulu kunzima ukubuthuthukisa. Ikhwalithi yezitimela inomthelela obalulekile ekuphepheni nasekusebenzeni kahle kwezokuthutha ngezitimela.
Ngaphambi kwenguquko yezimboni eYurophu, imizila yayenziwe ngokhuni olude olunobubanzi obungamasentimitha ambalwa. Ngaphansi komzila wokhuni, ucezu lokhuni lwalubekwa ngokuvundlile njalo ngamamitha amabili kuya kwamathathu njengezindawo zokulala. Izindawo zokulala zazisetshenziswa kakhulu ukulungisa umzila wokhuni ukuze ugcine ububanzi obubekiwe. Amasondo agijima ngaphezu kwawo nawo ayenziwe ngokhuni. Ngaleso sikhathi, insimbi yayingakhiqizwa ngezinga elikhulu, futhi insimbi nayo yayiyimpahla ebiza kakhulu. Umzila wokhuni kwakulula ukuwuguga nokuwudabula. Kamuva, abantu banamathisela amashidi ensimbi amade amancane ebusweni bawo futhi bawaqinisa ngezipikili. Emzileni, lokhu akugcini nje ngokwandisa impilo yenkonzo yomzila, kodwa futhi kunciphisa ukumelana nokungqubuzana, okuyisitimela esidala kakhulu.
INQUBO YOKUKHIQIZWA KOMKHIQIZO
Ubuchwepheshe kanye nenqubo yokwakha
Inqubo yokwakhaImizila Yesitimela Sesitimelaimizila ihilela ubunjiniyela obunembile kanye nokucatshangelwa ngokucophelela izici ezahlukahlukene. Kuqala ngokuklama ukwakheka kwemizila, kucatshangelwa ukusetshenziswa okuhlosiwe, isivinini sesitimela, kanye nendawo. Uma umklamo usuqediwe, inqubo yokwakha iqala ngezinyathelo ezilandelayo ezibalulekile:
1. Ukumba kanye nesisekelo: Ithimba lokwakha lilungisa inhlabathi ngokumba indawo bese lakha isisekelo esiqinile sokusekela isisindo kanye nokucindezeleka okubangelwa yizitimela.
2. Ukufakwa kwe-Ballast: Kubekwa ungqimba lwamatshe aqoshiwe, olwaziwa ngokuthi i-ballast, phezu kwendawo elungisiwe. Lokhu kusebenza njengengqimba ebamba ukushaqeka, enikeza ukuzinza, futhi kusiza ukusabalalisa umthwalo ngokulinganayo.
3. Izibopho Nokubopha: Izibopho zokhuni noma zekhonkrithi zibe sezifakwa phezu kwe-ballast, zilingisa isakhiwo esifana nohlaka. Lezi zibopho zinikeza isisekelo esiphephile semizila yesitimela yensimbi. Ziboshwa kusetshenziswa izipikili noma ama-clip athile, okuqinisekisa ukuthi zihlala ziqinile endaweni yazo.
4. Ukufakwa Kwesitimela: Izinsimbi zesitimela zensimbi ezingamamitha ayi-10, ezivame ukubizwa ngokuthi izinsimbi ezijwayelekile, zibekwe ngokucophelela phezu kwezibopho. Njengoba zenziwe ngensimbi yekhwalithi ephezulu, lezi zindlela zinamandla amakhulu nokuqina.
Uhlobo namandlaInsimbi Yesitimela Sesitimelazibonakaliswa ngobuningi obulinganiselwe (amakhilogremu) ngemitha ubude. Isibonelo, izinhlobo zesitimela ezijwayelekile zamanje eShayina zingama-43kg/m, 50kg/m, 60kg/m, 75kg/m, njll. Ubude obujwayelekile besitimela eShayina: 43kg/m bungama-12.5m noma ama-25m; ubude besitimela esingaphezu kwama-50kg/m bungama-25m, 50m, kanye nama-100m. Iya efektri yokushisela isitimela ukuze uyishisele kumzila omude ongamamitha angu-500, bese uyithutha uyise endaweni yokwakha bese uyishisela kubude obudingekayo.

IPHROJEKTHI
Inkampani yethu'Amathani angu-13,800 ezitimela zensimbi ezithunyelwa e-United States athunyelwa eTianjin Port ngesikhathi esisodwa. Umsebenzi wokwakha waqedwa ngojantshi wokugcina owabekwa kancane kancane emzileni wesitimela. Lezi zitimela zonke zivela emzileni wokukhiqiza womhlaba wonke wefektri yethu yesitimela kanye nensimbi, kusetshenziswa umhlaba wonke. Kwenziwe ngezindinganiso zobuchwepheshe eziphakeme kakhulu neziqinile.
Ukuze uthole ulwazi olwengeziwe mayelana nemikhiqizo yesitimela, sicela uxhumane nathi!

ISICELO
Isitimela SesitimelaUkwakheka kwengxenye yekhanda nakho kungenye yezindlela zokuthuthukisa ukuqina nokumelana nokuguguleka.
Esigabeni sekhanda lesitimela sokuqala, indawo yokunyathela ithambile, futhi ama-arcs ane-radius encane asetshenziswa kuzo zombili izinhlangothi. Kuze kube ngawo-1950 no-1960, kwatholakala ukuthi kungakhathaliseki ukuthi ikhanda lesitimela elaklanywa ekuqaleni lalinjani, ngemva kokuguguleka kwamasondo esitimela, ukuma kwe-tread phezulu kwesitimela cishe kwakuyisiyingi, kanti i-radius ye-arc kuzo zombili izinhlangothi yayinkulu kakhulu. Ukulingisa okuhlolayo kwathola ukuthi ukuxebuka kwekhanda lesitimela kuhlobene nokucindezeleka okukhulu kokuxhumana kwesondo nesitimela entanyeni yangaphakathi yekhanda lesitimela. Ukuze kuncishiswe umonakalo wokuqhekeka kwesitimela, wonke amazwe ashintshe ukwakheka kwe-arc yekhanda lesitimela ukuze kuncishiswe ukuguqulwa kwepulasitiki.
Okokuqala, amazwe alandele isimiso esinjalo ekwakhiweni kwe-rail head tread: i-arc ye-rail top tread ihambisana nosayizi we-wheel tread ngangokunokwenzeka, okungukuthi, usayizi we-tread arc, njenge-rail engu-59.9kg/m e-United States, i-rail head arc yamukelwa i-R254-R31.75-R9.52; i-rail engu-65kg/m ye-Soviet Union yangaphambili, i-rail head arc yamukela i-R300-R80-R15; i-UIC 60kg/m rail, i-rail head arc yamukela i-R300-R80-R13. Kungabonakala kusukela ngenhla ukuthi isici esiyinhloko somklamo wesigaba se-rail head yesimanje ukusetshenziswa kwama-curve ayinkimbinkimbi nama-radii amathathu. Ohlangothini lwe-rail head, kwamukelwa umugqa oqondile one-top encane kanye ne-bottom ebanzi, kanti umthambeka womugqa oqondile ngokuvamile u-1:20~1:40. Umugqa oqondile one-slope enkulu uvame ukusetshenziswa emhlathini ongezansi wekhanda le-rail, kanti i-slope ngokuvamile isukela ku-1:3 kuya ku-1:4.
Okwesibili, endaweni yokuguquka phakathi kwekhanda lesitimela kanye nonqenqema lwesitimela, ukuze kuncishiswe imifantu ebangelwa ukugxilisa ingqondo nokwandisa ukumelana kokungqubuzana phakathi kwe-fishplate kanye nonqenqema, kusetshenziswa ijika eliyinkimbinkimbi endaweni yokuguquka phakathi kwekhanda lesitimela kanye nonqenqema lwesitimela, futhi kusetshenziswa umklamo omkhulu werediyasi okhalweni. Isibonelo, isitimela se-UIC esingu-60kg/m sisebenzisa i-R7-R35-R120 endaweni yokuguquka phakathi kwekhanda lesitimela kanye nonqenqema. Isitimela saseJapan esingu-60kg/m sisebenzisa i-R19-R19-R500 endaweni yokuguquka phakathi kwekhanda lesitimela kanye nonqenqema.
UKUPHAKISHA NOKUTHUMELA
endaweni yokuguquka phakathi kwesinqe sesitimela kanye nephansi lesitimela, ukuze kufezwe ushintsho olubushelelezi lwesigaba, kwamukelwa nomklamo wejika eliyinkimbinkimbi, futhi ushintsho oluhamba kancane kancane luxhunywe kahle nokwehla kwephansi lesitimela. Njengesitimela se-UIC60kg/m, kufanele kusetshenziswe i-R120-R35-R7. Isitimela saseJapane esingu-60kg/m sisebenzisa i-R500-R19. Isitimela saseShayina esingu-60kg/m sisebenzisa i-R400-R20. Ukuthuthwa kwezitimela zesitimela ezinejubane eliphezulu kudinga usizo lwemishini yokuthutha yobungcweti namaqembu. Ngokuvamile, izitimela zesitimela ezinejubane eliphezulu zithuthwa ngesitimela. Ezigabeni zokuqala zokwakhiwa kwezitimela zesitimela ezinejubane eliphezulu zasekhaya, eminye imishini ebalulekile nezinto zokwakha kwakudingeka zingeniswe zivela kwamanye amazwe. Ngaleso sikhathi, ukuthuthwa komoya kwakuyindlela evamile yokuhamba. Kodwa-ke, izitimela zesitimela ezinejubane eliphezulu ezithuthukiswa futhi zakhiwe ngokuzimela ngokuvamile zithuthwa yisitimela ngokwaso. Isitimela ngasinye esinejubane eliphezulu singamamitha angama-25 ubude futhi sinesisindo samathani angama-30. Ngokuvamile kudinga izinqola ezimbili ngaphambili nangemuva ukuze kuqedwe yonke inqubo yokuhamba. Ngakho-ke, ngaphambi kokuthutha, kubalulekile ukuhlela umzila ngokucophelela futhi uhlole kusengaphambili ukuthi inqola iyahlangabezana yini nezidingo zokuhamba ukuqinisekisa ukuthi akukho monakalo noma izingozi zokuphepha ezizokwenzeka ngesikhathi sokuthutha.
AMANDLA ENKAMPANI
Kwenziwe eShayina, isevisi yekilasi eliphezulu, ikhwalithi ephezulu, idumile emhlabeni jikelele
1. Umphumela Wesilinganiso: Inkampani yethu inochungechunge olukhulu lokuhlinzeka kanye nefektri enkulu yensimbi, efinyelela imiphumela emikhulu kwezokuthutha kanye nokuthengwa kwempahla, futhi iba yinkampani yensimbi ehlanganisa ukukhiqiza kanye nezinsizakalo.
2. Ukwehlukahluka komkhiqizo: Ukwehlukahluka komkhiqizo, noma iyiphi insimbi oyifunayo ingathengwa kithi, ikakhulukazi ehilelekile ezakhiweni zensimbi, izinsimbi zensimbi, izinqwaba zeshidi lensimbi, amabhulakhethi e-photovoltaic, insimbi yesiteshi, amakhoyili ensimbi ye-silicon neminye imikhiqizo, okwenza kube lula ukukhetha uhlobo lomkhiqizo olufunayo ukuze luhlangabezane nezidingo ezahlukene.
3. Ukunikezwa okuzinzile: Ukuba nomugqa wokukhiqiza ozinzile kanye nochungechunge lokunikezwa kunganikeza ukunikezwa okuthembekile. Lokhu kubaluleke kakhulu kubathengi abadinga insimbi eningi.
4. Ithonya lomkhiqizo: Linethonya lomkhiqizo eliphezulu kanye nemakethe enkulu
5. Isevisi: Inkampani enkulu yensimbi ehlanganisa ukwenza ngokwezifiso, ezokuthutha kanye nokukhiqiza
