- I-10,3 km ye-Changtai Bridge inqumla i-Yangtze kwaye idibanisa indlela kunye nomzila kaloliwe.
- Ubude obuphambili be-1.208 m: idlula i-Russky Bridge (1.104 m).
- Izinto ezintsha: iintambo ze-carbon fiber tendon, iirobhothi ezingaphantsi kwamanzi, kunye neekhreyini ezihlakaniphile.
- Uvavanyo lomthwalo ngeelori ezili-110 kunye nomthamo ochaziweyo wesakhiwo seetoni ezingama-530.000.
I-China ivule ukuthuthwa kwezithuthi Changtai Bridge, umsebenzi omkhulu ovezwa njenge inkulu ibhulorho ehlala intambo ehlabathini ngobude bedesika kunye nesithuba esingundoqo, kwaye esomeleza ngokugqibeleleyo unxibelelwano phezu koMlambo iYangtze.
Ifumaneka kwiphondo laseJiangsu, ikhonkco lidibanisa Changzhou kunye ne Taizhou ngesakhiwo se Iikhilomitha ezingama-10,3, isithuba esiphakathi se Iimitha ezili-1.208 kunye neenqaba ze Iimitha ezili-350 phezulu, zonke kuqwalaselo lwe-multimodal oludibanisa indlela kunye nololiwe.
Yintoni eyenza iChangtai ibe yeyona bhulorho inkulu enentambo?
Ayisiyobhulorho yokunqunyanyiswa: kwibhulorho yokunqunyanyiswa idekhi ijinga kuyo iintambo eziphambili kwi-catenary; kwi-Changtai, yohlobo i-cable-ihlale, ibhodi igxininiswe ngokuthe ngqo kwiinqaba ngokusebenzisa iintambo ezithambekileyo, echaza ukuziphatha kwayo kwesakhiwo kunye neprofayili ebonakalayo.
Ukukhanya kwayo okuphambili kwe 1.208 m iphula irekhodi yebhulorho IsiRashiya eVladivostok (1.104 m) kwaye idibanisa nezinye izinto ezibalulekileyo: iChangtai yindawo ibhulorho yendlela-kaloliwe edibeneyo kwisakhelo sentsimbi yereferensi, kunye nokuqhubeka okubanzi kakhulu kweeplanga ze-lattice kudidi lwayo.
Ngokugunyaziswa, ixesha lokuhamba phakathi kweebhanki zombini zeYangtze lincitshiswe kakhulu: uhambo lusuka ngaphezu kwemizuzu engama-80 ukuya malunga nama-20, umtsi onyusa umsebenzi wezoqoqosho kunye ukuhamba kwemihla ngemihla kwidelta yomlambo.
Uyilo olunamanqanaba amabini lubandakanya, phezulu, a uhola wendlela emithandathu (i-100 km/h) kwaye, kwindawo engezantsi, ilungiselelo elingazange libonwe ngaphambili le-asymmetrical Umzila kaloliwe ohamba phakathi kwedolophu kwi-200 km/h ecaleni kwe indlela yasekuhlaleni eneendlela ezine (80 km/h), idityaniswe ecaleni.
Ubunjineli obutsha kunye nokwakha
Umsebenzi, owenziwe kwisithuba sexesha iminyaka emithandathu phantsi kobunkokheli be Ulwakhiwo loNxibelelwano lwaseTshayina, ishiye imigama eliqela: esona santya siphezulu sokuqhuba se iidrowa ezinkulu kudongwe oluyintlenga, i I-crane yokuqala ye-smart tower ngomthamo ongaphezulu kwe-10.000 yeetoni-yemitha kunye nenkqubela phambili kwi iipylons zentsimbi-concrete composite yenziwe ngendlela yoshishino.
Ngexesha lokuqala kolu hlobo lwezakhiwo zasetyenziswa i-carbon fiber tendons ukwenza iintambo ezidityanisiweyo zokuqina okuphezulu, ukungakhathali kangako kubushushu kunye nokusebenza ngcono ngokuchasene umhlwa, ukwandisa ukuqina kwenkqubo yokuqhafaza.
Iinqaba kwimilo ye idayimani, ye 350 m, dibanisa intsimbi kunye nekhonkrithi ukuphucula uzinzo. Iziseko zayo, zisonjululwe nge ii-caissons kuqiniswe, zenzelwe ukumelana ne imisinga enamandla yaseYangtze; njengoko umphathi weprojekthi uLi Zhen echaza, ukuqina "kuxhomekeke kwibhokisi engaphantsi kwamanzi."
I-asymmetry yebhodi engezantsi yenza umngeni wokulinganisa: iqela lenzululwazi eyintloko Qin Shunquan ilungiswe i ukuxinezeleka kwemitya kwicala likaloliwe ukwandisa lift kwaye, ngokunxuseneyo, ilinganiswe i imilo kunye nobunzima yecandelo ngalinye elenziwe ngaphambili ukwenzela ukuba, xa ziphakanyiswa kwaye zihlanganiswe, isakhiwo siya kuba kwinqanaba.
Ngexesha lokusebenza phantsi kwamanzi kwaqaliswa iirobhothi ezikrelekrele ekwaziyo ukuhamba kumhlaba ontsonkothileyo kunye nokucoca iindawo ze-caisson, ukunciphisa imisebenzi yokuntywila. Ukongeza, i I-crane enkulu yeedekhi zebhulorho yohlobo lwayo ukubeka amacandelo amakhulu ngokuchaneka kwemilimitha.
Uvavanyo, umthamo kunye nobubanzi
Ukuqinisekiswa kokugqibela kubandakanya uvavanyo nge Iilori ezili-110 y Iitoni ezingama-4.400 ukulayisha ngaxeshanye. Ngokutsho kwabaphathi bayo, isakhiwo sinokusingatha a umthamo we-530.000 yeetoni zeemetric, ukubonelela ngomda wokhuseleko phantsi kwemithwalo enzima.
El IYangtzekunye nabanye 6.300 km, ngowona mlambo mde e-Asiya kunye ne-hub engundoqo yolungiselelo; kumashumi eminyaka akutshanje inani leebhulorho phezu kwendlela yalo liye lakhula ukusuka kwishumi elinesibini ukuya ngaphezulu kwe-150, kunye neChangtai yomeleza le nkqubo ye indibaniselwano yomhlaba kwimpuma yeTshayina.
Ngokuphathelele iirekhodi, uChangtai ubambe irekhodi kwicandelo intambo-yahlala; inxalenye yayo, phakathi kweebhulorho iipendant igxininisa Huajiang Canyon e China, kunye manani ezibalaseleyo ukuphakama kunye nokukhanya, nangona yeyabantu a uhlobo olwahlukileyo lwesakhiwo.
Ngokudityaniswa kwayo ukukhanya okukhulu, imo yezothutho kathathu kunye nezinto ezintsha eyakhayo, ibhulorho yaseChangtai idibanisa umgangatho omtsha wokuwela imilambo ebanzi kwaye izisa uphuculo olubambekayo amaxesha, ukhuseleko kunye namandla kuhambo lwengingqi eJiangsu.
Ndingumntu othanda itekhnoloji ojike umdla wakhe we "geek" waba ngumsebenzi. Ndichithe ngaphezulu kweminyaka eli-10 yobomi bam ndisebenzisa itekhnoloji yokusika kwaye ndikhenkceza ngazo zonke iintlobo zeenkqubo ngenxa yokufuna ukwazi okumsulwa. Ngoku ndiqeqeshelwe ubugcisa bekhompyutha nakwimidlalo yevidiyo. Oku kungenxa yokuba ngaphezu kweminyaka emi-5 ndibhalela iiwebhusayithi ezahlukeneyo kwitekhnoloji kunye nemidlalo yevidiyo, ndisenza amanqaku afuna ukukunika ulwazi oludingayo ngolwimi oluqondakalayo kuye wonke umntu.
Ukuba unayo nayiphi na imibuzo, ulwazi lwam lusuka kuyo yonke into enxulumene nenkqubo yokusebenza yeWindows kunye ne-Android yeefowuni eziphathwayo. Kwaye ukuzinikela kwam kukuwe, ndihlala ndikulungele ukuchitha imizuzu embalwa kwaye ndikuncede usombulule nayiphi na imibuzo onokuba nayo kweli lizwe le-intanethi.
