Yini ochwepheshe ikutshela ngokwakha ibhuloho

Muva nje, i-Qilong Bridge yavalwa ngokusemthethweni, futhi ibhokisi lensimbi yokugcina enesisindo esingamathani angama-290 laphakanyiswa kahle ngomshini wokuqalisa ibhuloho. Uyini umshini webhuloho ohlu "ubuciko", kungani "enamandla"? Izolo, China Railway 25 Bureau I-Shop Shop Experity Chief Office Cliouner

Yena uBoliang uthe ngaphambi komshini webhuloho, ekwakheni leli bhuloho, ukunyakaza okuguqukayo kwephepha lokubhala, ukusetshenziswa kwendlu okuningana kudinga amathani ama-cheard abuntu, futhi angavele avele amathani ayi-100 eBeat sheet. Ngokuqamba okuqhubekayo kwesayensi nobuchwepheshe, ukuvela komshini wokuqalisa ibhuloho sekuxazulule i-tonnage enkulu kunazo zonke e-Beam Sheet Erection, kusukela ekuqaleni kwamathani ayi-160 kuya kumathani angama-900 anamuhla, noma amathani ayi-1,800, ukuqina nokuphepha kuqiniswe kakhulu.

Kusukela ngonyaka we-1990s, iChina isiqalile ukukhombisa amathuba okukhiqiza imishini yayo enkulu yokubhuka, futhi ithole impumelelo enkulu. Ngenani elikhulayo lamaphrojekthi okuhamba kwezitimela, ikakhulukazi ukuhlela kweNational "eziyisishiyagalombili mpo nasezivelile" eziyisishiyagalombili ezivundlile ", ukusetshenziswa kwemishini yokuqalisa ibhuloho kuvame kakhulu.

Uye wethula ukuthi imishini yokuqalisa ibhuloho isetshenziswa ikakhulukazi ekulweni kwezitimela zesitimela kanye namabhuloho aphezulu, njengokwakhiwa kwesitimela se-Wuhan-Gungzhou High-Speed ​​Railway kanye nakonke kusetshenziswa imishini yokuqalisa ibhuloho.

Ngabe "inamandla" umshini webhuloho? Ibhuloho le-36 km eside i-Hangzhou Bay Cross-Sea Bridge liyisimangaliso. Ngesikhathi sokwakha, ibhuloho lendlela kuzo zombili izinhlangothi zebhuloho elisetshenziswe amamitha angama-50 amamitha amancane e-girder, ngebhokisi elilodwa lembobo enesisindo esingu-1430 amathani. Kulindeleke ukuthi ifakwe ngamathani angama-1600 ohlobo lwethayi lokuphakamisa ugongolo, i-beam ezokuthutha imoto kanye nebhuloho elimisa umshini wokulayisha, ukuthutha kanye nokuqalisa imishayo. Isipiliyoni sokwakha sale mishini enkulu ye-Super sicishe ibe eyokuqala emhlabeni.

Eqinisweni, lapho i-Qilong Bridge yavalwa, kwasetshenziswa imishini evamile yebhuloho. Ekwakhiweni okwedlule kwamaphrojekthi we-foshan traffic, lolu hlobo lomshini webhuloho lwebhuloho lusetshenzisiwe. Ngokusho kukaYe Boliang, ngesikhathi se-Foshan engxenyeni ye-Guangzhou-Nanzhou-Guangzhou High-Speed ​​Railway Project, i-Ton-Ton-Ton AMEM yakhiwe ePier Bridge.

Esifundazweni sethu, imishini yokuqalisa ibhuloho ivela kumaphrojekthi amakhulu okuhamba. Isibonelo, ujantshi we-Wu-Guangzhou High-Speed, ujantshi we-Xiamen-Shenzhen, i-Dongguan-Huizhou intercity kanye nesitimela esisheshayo esinejubane elinama-200 km / h (250 km / h kusetshenziswa ibhokisi le-900 amathani noma amathani angama-700 ebhokisi le-girder; Ngaphezu kwalokho, kukhona ujantshi wesiGuangzhou-Zhuhai, i-Guiguangnan-Guangzhou Railway, Shenmao Railway Truck Freight Railway kanye noMkhandlu Wezingubo Zomugqa we-T-Cargo esebenzisa umshini we-T-Beam Bridge.

Kusukela kulo nyaka, i-Foshan izophinde yakha amaphrojekthi amaningi ojantshi wesitimela
