Steel Strand Synchronous Hoisting System Inoshandiswa KweSimbi Beam Erection yeGuojiatuo Yangtze River Bridge

Guojiatuo Yangtze River Bridge iri muNan'an District uye Jiangbei District. Ibhiriji renji-ranji rine hurefu hwakazara hwe1403.8 metres. Iyo shongwe yekuchamhembe inosvika 161.9 metres pakukwirira, shongwe yekumaodzanyemba inosvika 172.9 metres kureba, uye nzvimbo huru ndeye 720 metres. Kupedzwa kwebhiriji kuchabatanidzawo Liangjiang New District nebindu retii. Nguva yekutyaira munzvimbo iyi yakapfupikiswa kubva pamaminitsi makumi mana kusvika kumaminitsi gumi. Sechikamu chakakosha chemitsara mitanhatu yakatwasuka" yeChongqing's "nhanhatu yakatwasuka uye nomwe yakatwasuka" Expressway network, iyo yepamusoro yeGuojiatuo Yangtze Rwizi Bridge yakagadzirwa nenzira mbiri-nzira sere, uye yepasi nhanho njanji yekufambisa Line 8 The nzira yekuyambuka rwizi yakachengetwa uye inotarisirwa kupedzwa muna Gumiguru 2022.
Pazasi isu tinokuratidza iyo synchronization yekusimudzira maitiro. Chekutanga, 2,000-ton ro-ro ngarava inotakura zvinhu ichatakura yekutanga simbi truss girder yeGuojiatuo Yangtze River Bridge kuenda kurwizi pamusoro pazasi pepakati pepakati pepakati pezambuko. Mushure mezvo, girder yesimbi ine kureba kwemamita makumi maviri neshanu, hupamhi hwemamita makumi matatu nemapfumbamwe, kureba kwemamita 12.7 uye huremu hwematani mazana matanhatu nemakumi mashanu ne2 yakasimudzwa zvishoma nezvishoma nemajeko maviri ekusimudza anoenderana nedhizaini yakayerwa kusimudza huremu hwe800 matani. Pashure peanenge maawa matatu nehafu ebasa rakaoma revashandi vanopfuura 20, girder resimbi rokutanga rakaiswa zvinobudirira pachipfuramabwe.
