Thaum Lub Peb Hlis 3, Chongtai Yangtze River Tunnel 35 kV fais fab mov txhawb nqa qhov project tau ua tiav rau hauv kev ua haujlwm, suav nrog cov khoom siv tseem ceeb xws li cov khoom siv hloov pauv, cais cov keyboards, lub tshuab nqus tsev vacuum, hluav taws xob ntes thiab tso tawm fuses, thiab lwm yam. qhov project tseem ceeb nyob rau theem tom ntej ntawm qhov project. Node - qhov kev khawb ntawm lub ntiaj teb loj tshaj plaws txoj kab uas hla high-speed tsheb ciav hlau av-dej tshuav daim ntaub thaiv npog tshuab "Pilot" muab lub zog muaj zog.
Nws tau nkag siab tias "Pilot" shield tshuab siv rau qhov kev khawb av no muaj lub taub hau taub hau ntawm txoj kab uas hla ntawm 15.4 meters, lub cav loj ntev li ntawm 15.8 meters, tag nrho ntev ntawm 128 meters, thiab lub cav loj hnyav txog 2,600 tons. . Nws yog qhov ntev tshaj plaws ntawm ib lub taub hau excavation nyob rau hauv lub ntiaj teb no (11.325 kilometers) thiab qhov loj tshaj plaws txoj kab uas hla (15.4 meters) shield engineering machinery. Tom qab ua tiav kev sib dhos thiab ua haujlwm, "Pilot" yuav pib los ntawm No. 3 ncej hauv Wan'an Village, Miao Town, Chongming, thiab qhov tob 11,325.5 meters hla tus dej Yangtze mus txog qhov thib 2 ncej hauv Taicang City, Jiangsu Province. , txuas Chongming, Shanghai thiab Taigang, Jiangsu Province.
Lub tshuab tiv thaiv yuav tsum tau khawb tsis tu ncua 24 teev hauv ib hnub, thiab txhim khu kev qha tsis muaj kev cuam tshuam fais fab tau dhau los ua tus yuam sij rau nws lub zog. Lub tshuab hluav taws xob ua kom muaj kev ntseeg siab thiab kev nyab xeeb ntawm cov khoom siv hluav taws xob los ntawm kev ua tib zoo teeb tsa cov khoom siv hluav taws xob thiab cov hluav taws xob sib cais. Nyob rau tib lub sijhawm, lub tshuab nqus tsev Circuit Court breaker tuaj yeem txiav tawm sai sai thaum tsim nyog kom tsis txhob nthuav dav ntawm qhov txhaum. Surge arresters thiab drop-out fuses zoo tiv thaiv lub hwj huam mov system los ntawm kev puas tsuaj los ntawm xob laim thiab overload tam sim no.
Qhov kev txhawb nqa hluav taws xob ntawm qhov project yuav siv rau lub Ib Hlis 4, 2024. Txoj haujlwm tshiab kev tsim kho vaj tse ntev ntawm cov kav dej yog 988 meters, 35 kV overhead kab yog 7.63 kilometers, thiab cables (ob chav sib cais) yog 1.2 kilometers. Nyob rau tib lub sijhawm, qhov project kuj suav nrog kev teeb tsa thiab kev debugging ntawm transformers los xyuas kom meej tias lub tshuab tiv thaiv tau txais kev ruaj khov thiab muaj zog txaus. Lub sijhawm tsim kho qhov project yog luv luv thiab lub sijhawm xa hluav taws xob nruj. Lub Xeev Grid Shanghai Chongming Fais Fab Lub Tuam Txhab, uas yog lub luag haujlwm rau kev siv ntawm qhov project, tam sim ntawd tsim ib pab pawg neeg ua haujlwm tshwj xeeb, ua tib zoo npaj lub sijhawm teem sijhawm thiab phau ntawv ua haujlwm, thiab nias lub pob "ceev nrawm" rau kev ua haujlwm. Kev ntsuas xws li cov txheej txheem sib luag thiab kev sib koom ua ke sab hauv thiab sab nraud tau txais kev pom zoo los xyuas kom meej tias cov khoom siv hluav taws xob txhawb nqa tau muab tso rau hauv kev ua haujlwm zoo raws li lub sijhawm teem tseg, tso lub hauv paus ruaj khov rau kev ua kom zoo ntawm kev ua haujlwm tom ntej ntawm qhov av excavation.
Wang Yi, tus thawj coj ntawm Chongtai Yangtze River Tunnel Equipment ntawm Tuam Tshoj Railway Tunnel Bureau, tau hais tias Chongtai Yangtze River Qhov Tunnel tam sim no yog lub ntiaj teb-chav kawm high-ceev tsheb ciav hlau hla-dej qhov project nrog cov qauv kev tsim kho siab tshaj plaws, qhov ntev tshaj plaws kev khawb av, thiab qhov loj tshaj plaws. Nws yog ib feem tseem ceeb ntawm Shanghai-Nanjing-Hefei high-speed rail. . Tom qab ua tiav ntawm txoj haujlwm, yuav tsim cov channel tshiab nrawm ntawm thaj chaw Shanghai nroog, Nanjing nroog cheeb tsam thiab Hefei nroog cheeb tsam. Nws yuav yog ib qho tseem ceeb rau kev txhim kho cov txheej txheem ntawm txoj kev tsheb ciav hlau raws tus dej Yangtze, ua haujlwm kev sib koom tes ntawm txoj kev loj hlob ntawm Yangtze River Economic Belt, thiab txhawb kev sib koom ua ke zoo ntawm Yangtze River Delta. kev loj hlob yog qhov tseem ceeb heev. Tom qab tag nrho cov no, nws yog inseparable los ntawm kev ruaj ntseg kev lag luam thiab kev koom tes zoo ntawm cov khoom tseem ceeb xws li hloov cov txee, cais cov keyboards, lub tshuab nqus tsev Circuit Court breakers, xob laim ntes, tso tawm fuses thiab transformers.
