Umkhondo we-motor orthy mveliso ophumeleleyo kwicandelo eliphambili lentsimbi ye-Rilay Loreway Landela kwaye ulandelele i-Q275 20MK RIL REE
Uloliwe kaRailroadNgokwenziwa ngokwenziwa kubude obungaphantsi kweenyawo ezingama-30, iinyawo ezingama-39, okanye iinyawo ezingama-60, nangona iindlela ezinde zinokufumana iiprojekthi ezithile. Olona hlobo luqhelekileyo lwentsimbi esetyenziswe kwiitreyini zikaloliwe yaziwa ngokuba yi-flat-boril eflethi, eneflethi kunye namacala amabini anesidima. Ubunzima bomlo, owaziwa ngokuba "yingxondorha," iyahluka ngokuxhomekeke kwiimfuno ezithile zomgaqo kaloliwe.
Inkqubo yemveliso yeI-Railroad trailkubandakanya amanyathelo aliqela, kubandakanya:
- Ukulungiselela izinto ezibonakalayo: ukuveliswa kweI-Railway Steeliqala ngokukhetha kunye nokulungiswa kwezinto ezingafunekiyo, ngokwesiqhelo zentsimbi ezisemgangathweni. Ezi billets zenziwe nge-ore yentsimbi kunye nezinye iisayina, ezinjenge-limestone ne-coke, ezinyibilikisiwe ngesililo esivuthayo.
- Ukuphoswa ngokuqhubekayo: Intsimbi enyibilikisiweyo emva koko idluliselwe kumatshini wokuphosa okuqhubekayo, apho kutshutshiswa khona kwimibumbe ukwenza imingxunya emide ebizwa ngokuba yi-Billits. Ezi billets zihlala zixanda kwaye zinike izinto zokuqala zenkqubo yokuveliswa kololiwe.
- Ukufudumeza nokuqengqeleka: Ii-billets zaphinde zahlala kwiziko ukuya kwiqondo lobushushu elibavumela ukuba babekwe ngokulula kwayeumkhondo we-railroad yentsimbi. Emva koko badutyulwa ngothotho lwee-mills eziqengqelekayo, ezigqobhoza uxinzelelo olukhulu lokwakha ii-billets kwiprofayili enqwenelekayo. Inkqubo eqengqelekayo ibandakanya ukuphindaphinda okukhulu kokudlulisela ii-billets ngokusebenzisa ii-mills eziqengqelekayo ukuba zizibethe kancinci kubabini.
- Ukupholisa kunye nokusika: Emva kwenkqubo eqengqelekayo, iindonga zipholile kwaye zisikwe kubude obufunekayo. Ngokwesiqhelo banqunyulwa kubude obungaphantsi kweenyawo ezingama-30, iinyawo ezingama-39, okanye iinyawo ezingama-60, nangona izilali ezinde zinokuveliswa nazo iiprojekthi ezithile.
- Ukuhlolwa kunye nonyango: Iindonga ezigqityiweyo zihlolwa ngokungqongqo ukuqinisekisa ukuba ziyafezekisa imigangatho kunye neenkcazo. Iimvavanyo ezahlukeneyo, ezinjengemilinganiselo yobungakanani, uhlalutyo lweekhemikhali, kunye novavanyo lomatshini, ziqhutywa ukuqinisekisa umgangatho kunye nokunyaniseka koolo lwesiqwizi. Nasiphi na isiphene okanye ukungafezeki kuyachongwa kwaye bathathelwa ingqalelo.
- Unyango lomphezulu: Ukomeleza ukuqina kunye nokunganyangeki koololiwe, banokufumana iinkqubo zonyango. Oku kunokubandakanya ukusebenzisa iingubo zokukhusela, ezinjengepeyinti ye-anti-corrosion okanye i-galvanition, ukuthintela ukuthuka kunye nokunyanzelwa, ngaloo ndlela kwadlulisa ixesha lololiwe.
- Ukuhlolwa kokugqibela kunye nokupakisha: Nje ukuba oololiwe baphathwe kwaye baphumelele uhlolo lokugqibela, bapakishwe ngononophelo kwezothutho kwiindawo zololiwe. Ukupakishwa kwenzelwe ukukhusela izilolo kulo naluphi na umonakalo ngexesha lohambo.
Iimbonakalo
Iindonga zensimbiNgaba yinxalenye ebalulekileyo yeendlela zoololiwe kwaye unezinto eziphambili:
I-1. Amandla kunye nokuqina: Iindebe zentsimbi zenziwe ukusuka kwintsimbi esemgangathweni ephantsi, ebanika amandla agqwesileyo kunye nokuqina. Ziyilelwe ukumelana nemithwalo enzima, iimpembelelo ezihamba rhoqo, kunye neemeko zemozulu ezigqithisileyo ngaphandle kokusebenza kakuhle okanye ukonakala.
2. Umthamo ophezulu wokuThengwa ngumthwalo: Iintsimbi zensimbi zinikezelwe ukuxhasa ubunzima boololiwe kunye nempahla yabo. Banokuphatha imithwalo enzima kwaye basasaze ubunzima ngokulinganayo, ukunciphisa umngcipheko wokungaphumeleli kwekhondo okanye ukungcungcutheka.
3. Nxibelelanisa ukuxhathisa: Iintsimbi zentsimbi zinokunganyangeki kakhulu ukunxiba kunye ne-abrasion. Oku kubalulekile kubaqeqeshi kuhlala kuqhuba kwiindlela, kubangela ukungqubana nokunxiba ngokuhamba kwexesha. Intsimbi esetyenziselwa ukuveliswa kololiwe ikhethwe ngokukhethekileyo amandla ayo okuxhathisa ukunxiba nokugcina ubume bayo kangangexesha elide lokusetyenziswa okuqhubekayo.
4. Ukuchaneka kwe-Dimential: Iintsimbi zenziweyo zenziwa kulungelelwaniso olungqongqo lokuqinisekisa ukungqinelana kunye nokusebenza kakuhle kunye nezinye izinto zikaloliwe, ezinje ngamaqela kaloliwe, amatye omnqamlezo, kunye nokuthabatha. Oku kuvumela intshukumo engagungqiyo yoololiwe ngasekupheleni kwaye kunciphisa umngcipheko wesidanga okanye ukuphazamiseka.
I-5. Ukuxhathisa i-Corrosion: Iintsimbi zentsimbi zihlala ziphathwa ngamagquma okhuselayo okanye i-Gravanization yokuphucula ukumelana kwazo ekusuleni. Oku kubaluleke kakhulu kwimimandla enomswakama okuphezulu, iindawo ezinobunkunkqele, okanye ukuveza amanzi, njengokuvela okunokwenza buthathaka ooloyiso kwaye batyeshele ingqibelelo yabo.
6. Ubomi obude: Iintsimbi zentsimbi zinobomi beenkonzo ezinde, ezinegalelo ekuhlawuleni indleko zendlela yoololiwe. Ngolondolozo olufanelekileyo kunye novavanyo lwamaxesha, iindlela zentsimbi zinokuthatha iminyaka emininzi ngaphambi kokuba kufuneke itshintshwe.
7. Ukulungelelaniswa komgangatho: Iidrails zentsimbi zenziwa ngokwemigangatho yeshishini kunye neenkcazo ezichazwe yimibutho efana noMbutho waseMelika ukuba uvavanywe kunye nezixhobo (i-IIC). Oku kuqinisekisa ukuba izilali zensimbi kubavelisi abahlukeneyo zinokutshintsha ngokulula kwaye zidityaniswe kwiinkqubo ezikhoyo zikaloliwe.
Isicelo
I-rails zensimbi isetyenziselwa ukwakhiwa kweetrekhi zoololiwe, kuvumela oololiwe ekuzonwabiseni abakhweli kunye neempahla ngokufanelekileyo. Nangona kunjalo, banezinye iinkqubo ezininzi kunye:
I-1. I-tram kunye neenkqubo zololiwe ezilula: iindlela zentsimbi zisetyenziswa kwitram kunye neenkqubo zokuhamba ezilula zokukhokela amavili ezithuthi ecaleni kwendlela ekhethiweyo. Ezi nkqubo zihlala zifumaneka kwiindawo ezisezidolophini kwaye zibonelela ngezothutho kwizixeko nakwiidolophu.
I-2. Imizi-mveliso kunye nemigodi yemigodi: iindlela zentsimbi zisetyenziswa kwizicwangciso zemizi-mveliso, ezinje ngefektri okanye iifayile, ukuxhasa ukuthuthwa kwezixhobo kunye nezixhobo. Zihlala zibekwa ngaphakathi kwiindawo okanye iiyadi, ziqhagamshela iindawo ezahlukeneyo zomsebenzi okanye iindawo zokugcina.
I-3. Izibuko kunye ne-termil ye-termils: iindlela zentsimbi zisetyenziswa emaphethelweni kunye neetheminali ukwenza lula intshukumo yempahla. Zibakwe phezu kwee-docks okanye kwiindawo zokugcina ukwenza ukuba ukulayisha kunye nokulayisha iinqanawa kunye nezikhongozeli.
I-4. Iipaki zomxholo kunye ne-roller coasters: iindlela zentsimbi yinxalenye ye-roller coasters kunye nezinye iipaki zokuzonwabisa. Babonelela ngesakhiwo kunye nesiseko sekhondo, ukuqinisekisa ukhuseleko kunye nokusebenza kakuhle kwamaqhinga.
5. Iinkqubo zokuhambisa: iindlela zentsimbi zinokusetyenziswa kwiinkqubo zokuhambisa, ezisetyenziswa kwimizi-mveliso eyahlukeneyo ukuthutha iimpahla okanye izinto eziqingqiweyo. Banika umkhondo oqingqiweyo kwaye othembekileyo kwiibhanti ezidlulayo ukuba ziqhubeke.
I-6. Iitrekhi zethutyana: iindlela zentsimbi zinokusetyenziswa njengamakhondo okwethutyana kwiindawo zokwakha okanye kwiiprojekthi zolondolozo. Bavumela intshukumo yoomatshini nezixhobo ezinzima, ukuqinisekisa imisebenzi esebenzayo ngaphandle kokubangela umonakalo kumhlaba osisiseko.
