Steel Strand Synchronous Hoisting System Siv rau Steel Beam Erection ntawm Guojiatuo Yangtze River Choj

Guojiatuo Yangtze River Choj nyob hauv Nan'an District thiab Jiangbei District. Nws yog ib tug pej xeem-rail choj nrog ib tug ntev ntawm 1403.8 meters. Sab qaum teb ntauwd yog 161.9 meters siab, sab qab teb pej thuam yog 172.9 meters siab, thiab lub ntsiab span yog 720 meters. Kev ua tiav ntawm tus choj tseem yuav txuas Liangjiang New District mus rau lub vaj tshuaj yej. Lub sijhawm tsav tsheb hauv cheeb tsam tau luv los ntawm 40 feeb mus rau 10 feeb. Raws li ib feem tseem ceeb ntawm rau txoj kab ntsug" ntawm Chongqing's "rau kab rov tav thiab xya ntsug" txoj kev nthuav dav, theem sab saud ntawm Guojiatuo Yangtze River Choj yog tsim los nrog ob-txoj kev yim txoj kab, thiab theem qis yog rail transit Kab 8. Kev hla dej hiav txwv tau tshwj tseg thiab xav tias yuav ua kom tiav thaum Lub Kaum Hli 2022.
Hauv qab no peb yuav qhia koj cov txheej txheem hloov kho synchronization. Ua ntej, 2,000-tuj ro-ro cargo nkoj yuav thauj thawj steel truss girder ntawm Guojiatuo Yangtze River Choj mus rau tus dej saum npoo hauv qab ntawm qhov nruab nrab ntawm tus choj loj. Tom qab ntawd, steel truss girder nrog qhov ntev ntawm 20.5 meters, qhov dav ntawm 39 meters, qhov siab ntawm 12.7 meters thiab qhov hnyav ntawm 652 tons tau maj mam nqa los ntawm ob lub synchronous lifting jacks nrog tus qauv tsim ntsuas qhov hnyav ntawm 800 tons. Tom qab ze li ntawm peb thiab ib nrab teev ntawm kev ua haujlwm hnyav los ntawm ntau tshaj 20 tus neeg ua haujlwm, thawj cov hlau truss girder tau ua tiav rau ntawm lub sling.
