Ukuthuthukiswa Kobunjiniyela Kwezinqola Ezingaphansi Kwezinqola Zensimbi Ezinzima Zezinhlelo Ze-Tunnel Trestle

Kumaphrojekthi amakhulu emisele ewela imifula enyakatho yeShayina, amaqembu okwakha adinga i-trestle yemisele enzima ehambisana ne-trolley yesibili kanye nomshini wokubhoboza imisele. Yakhelwe ukusingatha imithwalo enamandla engaphezu kwamathani angu-25, le trestle kumele futhi ihambe njalo ezimweni zomhubhe omanzi, onodaka, kufaka phakathi izingxenye ezinemigoqo ethambekile.

Izinselele Zobuchwepheshe

Ngesikhathi sesigaba sokuklama, ithimba lephrojekthi libhekane nezinselele eziningana ezibalulekile zobunjiniyela:

1. Amandla Okuthwala Okuguquguqukayo Komhlaba:Ukuqongelela kwamanzi njalo nodaka oluthambile phansi komhubhe kwadinga ishasi elinengcindezi encane yomhlabathi ukuze kuqedwe ingozi yokwehla ngaphansi kwemithwalo esindayo.

2. Ukukhathala Kwesakhiwo Okubangelwa Ukulayisha Okunzima Nokujikelezayo: I-chassis ye-trestle kumele ibekezelele ukucindezeleka okuphindaphindiwe okushintshana ngesikhathi sokunyakaza okuqhubekayo. Izakhiwo zensimbi yekhabhoni ezijwayelekile zivame ukuqhekeka ngokukhathala ngaphansi kwalezi zimo.

3. Indawo Yokusebenzela Evalekile Kakhulu: Iphrofayili yomhubhe omncane idinga uhlelo lokuhamba olukwazi ukubeka indawo ngendlela enembile kanye nokuqondisa okuthembekile, okushesha kancane ngenkathi ingaphansi komthwalo ogcwele.

Isixazululo Sobuchwepheshe

Ukuze kuxazululwe lezi zinselele, ithimba lobuchwepheshe le-YIKANG laklama ikhambi lokuhamba elenziwe ngokwezifiso elilandelwa ngensimbi, eliqukethe izinto ezintsha ezilandelayo ezibalulekile:

1. Ukwakheka Kwesakhiwo Nobuqotho Bezinto Ezibonakalayo

Uhlaka oluyinhloko lwesitimela esingaphansi kwesitimela lwakhiwe ngensimbi enamandla aphezulu ye-Q355D, enikeza amandla okukhiqiza aphezulu cishe ngo-40% kunezinto ezijwayelekile ze-Q235. Ukuhlaziywa Kwe-Finite Element (FEA) kwakubalulekile ekwakhiweni, kuqondisa ukuqinisa amasu ezindaweni ezibucayi zokucindezeleka ukuqinisekisa isilinganiso sokuphepha esiqinile ngaphansi kwemithwalo emikhulu yamathani angu-25-30.

2. Ukushisela Nokwakha Ochwepheshe

Ngenxa yezidingo zokuphepha ezibalulekile, wonke ama-weld abalulekile enziwa ngesandla ngabashiseli abangochwepheshe abangochwepheshe bemishini esindayo iminyaka engaphezu kweshumi.

• Inqubo Elawulwayo:Inqubo eqinile ehilela ukushisa kusengaphambili okunezigaba eziningi kanye nokushisela okunezingqimba eziningi, okudlula okuningi kuqinisekisa ukuhlanganiswa kwezimpande okuphelele.

• Ukuqinisekiswa Okuqinile:I-weld ngayinye idlula ku-100% Visual Testing (VT), ehambisana ne-Ultrasonic Testing (UT) ezindaweni zokuxhumanisa izihluthulelo. Lokhu kuqinisekisa ukuthi akukho ziphazamiso zangaphakathi—njengokuvuleka noma ukuqhekeka—zokumelana okukhulu kokushayisana.

3. Idrayivu Nokusebenza Okulungiselelwe

• Ukucindezela Komhlaba Okuphansi Kakhulu:Izicathulo ezibanzi kanye nokulungiswa kwe-roller okwenziwe kahle kugcina ingcindezi yomhlabathi ku-≤55 kPa, okuvumela ukusebenza okuthembekile ezimweni ezithambile, ezinodaka.

• Ukudonsa Okunamandla Kakhulu:Uhlelo lokushayela oluhlanganisiwe lwe-hydraulic lune-braking ezenzakalelayo, luqinisekisa ukuma okuzinzile kanye nokuqala okubushelelezi ezindaweni ezithambekile.

Imiphumela Yokusebenza

Sekuphele izinyanga ezingu-12 isebenza ngokuqhubekayo selokhu yasetshenziswa, i-chassis ilethe ukuthembeka okumangalisayo ngemiphumela elandelayo ebonisiwe:

• Ukusebenza Okungaphazanyiswa:Kufezwe isikhathi sokungasebenzi kwesistimu yokuhamba phakathi nesigaba sokuthuthuka komhubhe, okusekela ngqo ukuqedwa kwephrojekthi ngesikhathi esibekiwe.

• Ukuqina Okuqinisekisiwe:Izilinganiso zasensimini ziqinisekisa ukuthi amazinga okuguguleka kwezicathulo zomkhondo kanye nama-roller okusekela ezimweni zamatshe ahuzukayo aphansi kakhulu kunalokho obekulindelwe, okwandisa impilo yenkonzo elinganisiwe ngo-60%.

• Ukuphepha Okuthuthukisiwe Endaweni:Umklamo olungiselelwe kahle, ophansi phakathi nendawo yamandla adonsela phansi uthuthukise kakhulu ukuzinza kwezinhlangothi ngesikhathi sokunyakaza kwe-trestle, okwandisa ukuphepha kokusebenza.

Le phrojekthi iqinisekisa ukuthi ngezinhlelo zokusebenza zengqalasizinda ezinobungozi obukhulu nezinomthwalo omkhulu njenge-tunnel trestles, ikhambi elenziwe ngokwezifiso lihlala lidlula umkhiqizo ongekho eshelufini. Ngokulawula ngokucophelela ukukhethwa kwezinto, ubuchwepheshe bokushisela, kanye nobuchwepheshe besakhiwo, i-YIKANG iphumelele ukuletha isisekelo se-powertrain esiqinile nesiqinile semishini ye-tunnel esindayo ebalulekile.
