iStrand Strand Synchronous Hoisting System eSetyenziselwa ukwakhiwa kwentsimbi yentsimbi kwiBhulorho yoMlambo iGuojiatuo Yangtze

Umqadi wokuqala weBhulorho yaseGuojiatuo unyuswe ngempumelelo

NgoNovemba 22, 2021, ibhulorho yokuqala yentsimbi ye-Guojiatuo Yangtze River Bridge yakhiwe ngempumelelo, ebonisa ukuba ukwakhiwa kweBhulorho yoMlambo iGuojiatuo Yangtze, eyona inkulu phakathi kweebhulorho ezakhiwe kwiindawo eziphezulu zoMlambo waseYangtze, sele ngokusemthethweni. wangena ukwakhiwa kwentsimbi truss girder. I-Fast Lane.I-Canete ibonelela nge-hoisting kunye ne-synchronous hoisting systems ye-strands kunye nezixhobo zokunyusa ezincedisayo.

Ibhulorho yoMlambo iGuojiatuo Yangtze ikwiSithili saseNan'an kunye neSithili saseJiangbei. Yibhulorho kaloliwe enobude obuziimitha ezingama-1403.8. Inqaba esenyakatho yi-161.9 yeemitha ukuphakama, inqaba esezantsi yi-172.9 yeemitha ukuphakama, kwaye ubude obuphambili buziimitha ezingama-720. Ukugqitywa kwebhulorho kuya kudibanisa iSithili esitsha saseLiangjiang kwigadi yeti. Ixesha lokuqhuba kwindawo lincitshiswe ukusuka kwimizuzu engama-40 ukuya kwimizuzu eyi-10. Njengenxalenye ebalulekileyo yemigca emithandathu ethe nkqo" yeChongqing "isithandathu esithe tye kunye nesisixhenxe esithe nkqo" sothungelwano lwendlela, inqanaba eliphezulu leBhulorho yoMlambo iGuojiatuo Yangtze iyilwe ngeendlela ezimbini ezisibhozo, kwaye umgangatho osezantsi ngumzila kaloliwe wokuhamba Umgca 8. Umjelo wokuwela umlambo ugciniwe kwaye kulindeleke ukuba ugqitywe ngo-Okthobha wama-2022.
Ngezantsi siza kukubonisa inkqubo yokuphucula ungqamaniso. Okokuqala, inqanawa ye-2,000-toni ye-ro-ro iya kuthutha i-truss girder yokuqala yentsimbi ye-Guojiatuo Yangtze River Bridge ukuya kumphezulu womlambo ongaphantsi kombindi we-span enkulu yebhulorho. Emva koko, intsimbi yentsimbi enobude obuziimitha ezingama-20.5, ububanzi obuziimitha ezingama-39, ubude beemitha ezili-12.7 kunye nobunzima beetoni ezingama-652 yanyuswa kancinci kancinci ziijekhi ezimbini zokuphakamisa ezihambelanayo kunye noyilo olulinganiswe ngobunzima bokuphakamisa iitoni ezingama-800. Emva kweeyure ezintathu ezinesiqingatha zomsebenzi onzima owenziwa ngabasebenzi abangaphezu kwama-20, intsimbi yokuqala yokuhlanganisa intsimbi yafakwa ngempumelelo kwisilingi.
