Ua kom nrawm dua kev tsim kho ntawm lub kaw lus thauj mus los kom tiav. Koom ua ke rau hauv lub teb chaws lub teb chaws peb-seem kev thauj mus los backbone network, txhawb kev txhim kho ntawm "ib lub ntsiab thiab ob tis" kev thauj mus los ntawm hom "Y" mus rau hom "△", thiab ua kom nrawm dua kev tsim kho ntawm lub caij nyoog niaj hnub nrog plaub qhov kev taw qhia ntawm sab hnub tuaj-sab hnub poob, sab qaum teb-sab qab teb, plaub-kwj dej kev koom ua ke, thiab plaub-txoj kev sib txuas ntawm hlau, dej, pej xeem thiab huab cua. Kev thauj mus los sib koom ua ke. Qaib ntxhw Excavator sprocket

——Kev qhia luv luv ntawm daim ntawv tshaj tawm ntawm 12th Provincial Party Congress

Thaum 10:30 teev sawv ntxov rau lub Xya Hli 14, lub hnub kub hnyiab zoo li hluav taws. Qhov chaw tsim kho ntawm Yanji Yangtze River Choj, uas yog ib qho project tseem ceeb ntawm peb lub xeev, tau nrov nrov raws ntug dej Yangtze hauv Songshan Village, Yanji Town, Ezhou City.

Ntawm qhov chaw tsim kho ntawm lub pej thuam loj ntawm ntug dej sab qab teb ntawm kwv yees li 1,000 square meters, plaub lub tshuab khawb av ua lub suab nrov nrov. Lub tshuab khawb av tuab tau ncig thiab tshawb nrhiav hauv qab, nrog rau txoj kab uas hla ntawm 3.2 meters. Lub suab nrov ua rau ob txhais taw tshee me ntsis, thiab cov av nkos uas tau khawb tau raug thawb mus rau hauv pas dej av nkos kom ua rau cov av nkos poob.

"Nrog nws, nws tau lees tias yuav ua tiav kev tsim kho ntawm 56 lub hauv paus ua ntej dej siab ntawm tus dej Yangtze." Taw tes rau ib qho ntawm 40-meter-siab ntsuab "Big Macs", tus thawj tswj hwm qhov project hws ntawm CCCC Second Aviation Bureau Wu Xiaobin luag nyav ntawm nws lub ntsej muag tsaus ntuj.

44.8 degrees Celsius! Ib sab ntawm lub tshuab khawb av Shanhe ntse no, tus neeg sau xov xwm ntawm Hubei Daily tau siv lub ntsuas kub los ntsuas qhov kub tiag tiag. Txawm li cas los xij, "lub tshuab khawb av loj" no tsis ntshai qhov kub siab, thiab nws khawb tob rau hauv av ib 'meter' ib 'meter'. Tus tsav tsheb, Master Zhao, ua haujlwm ntsiag to hauv lub cab nrog qhov siab ntau dua 10 meters.

Lub pier tseem ceeb ntawm lub pej thuam sab qab teb ntawm Yanji Yangtze River Choj siv lub hauv paus pawg, thiab qhov tob tshaj plaws yuav tsum tau khawb mus rau 76 meters. Qhov nyuaj dua yog tias lub pier nyob ntawm ntug ntawm thaj chaw geological fault, nrog rau kev faib cov pob zeb sib txawv thiab lub zog pob zeb tsis sib xws. Yog tias siv lub tshuab laum thiab lub tshuab laum rotary rau kev tsim kho, nws nyuaj rau ua tiav txoj haujlwm raws sijhawm.

Hubei CCIC Yanji Choj Tuam Txhab thiab CCCC Second Aviation Bureau Project Department tau txiav txim siab nqis peev ntau dua 20 lab yuan los qhia txog lub tshuab drilling rotary muaj zog tshaj plaws hauv Suav teb los koom nrog kev tsim kho lub hauv paus pier pile tseem ceeb. Nws tau nruab nrog lub zog ob npaug tsib lub cev muaj zog. Tag nrho lub tshuab hnyav 450 tons, uas sib npaug rau qhov hnyav ntawm yuav luag 400 lub tsheb. Qhov siab tshaj plaws drilling txoj kab uas hla tuaj yeem ncav cuag 7 meters, thiab qhov tob tshaj plaws drilling tuaj yeem ncav cuag 170 meters, uas tuaj yeem ua tau raws li qhov yuav tsum tau ua ntawm qhov loj txoj kab uas hla tob thiab qhov nyuaj siab. Cov kev cai rau cov pob zeb-socketed piles.

Qhov khawv koob ntawm "super drill" nyob qhov twg? Guan Aijun, tus thawj coj ntawm Hubei Communications Yanji Bridge Company, taw tes rau lub cab siab thiab hais tias muaj ib qho screen pom ntawm nws, thiab ntau qhov chaw tuaj yeem pom thaum lub sijhawm tsim kho, thiab lub kaw lus tuaj yeem ua kom cov ntaub ntawv xws li qhov ntsug ntawm lub qhov. Nws kuj tseem tuaj yeem ceeb toom thaum muaj kev phom sij. Ntxiv mus, nws tuaj yeem tho ib pawg hauv qhov nruab nrab ntawm 5 hnub, uas yog ntau dua 5 zaug sai dua li cov rigs drilling ib txwm muaj, thiab tuaj yeem "gnaw" cov pob txha tawv xws li basalt.

Thaum Lub Peb Hlis 24, "Super Drill" tau raug xa mus rau thawj zaug, thiab nws tau qhia txog lub zog loj hauv kev tsim kho Yanji Yangtze River Bridge. Txog tam sim no, 13 lub hauv paus pile tau ua tiav nrog qhov zoo.

Nrog rau tag nrho cov peev txheej ntawm 13.766 billion yuan, qhov project Second E-Huang River Crossing Channel (Yanji Yangtze River Bridge and Connection) tau nqis peev thiab tsim los ntawm Hubei Communications Investment Group, nrog qhov ntev li ntawm 26 kilometers. Nws lub choj tseem ceeb siv lub choj dai 1860-meter los hla tus dej ib zaug, thiab tam sim no nws yog lub choj dai cable plaub-dej loj tshaj plaws hauv ntiaj teb.

"Super Drill" tsuas yog ib qho me me ntawm Yanji Yangtze River Bridge qhov project zoo xyoo pua ntawm Ping An. Hauv qhov chaw tsim kho choj thoob ntiaj teb no, daim duab ntawm "kev txawj ntse" seev cev txhua qhov chaw. Qaib ntxhw Excavator sprocket

Guan Aijun tau qhia tias nrog kev pab los ntawm cov khoom siv tsim choj, cov ntu tseem ceeb ntawm lub hauv paus tseem ceeb ntawm lub tsev loj, cov ntsia hlau, thiab cov choj mus rau ob sab ntawm Yanji Yangtze River Choj tau pib ua tiav, thiab lawv tab tom siv zog ua tiav lub hom phiaj peev ntawm 3 billion yuan xyoo no.

Cov choj hla tus dej Yangtze los tsim kom muaj kev thauj mus los niaj hnub. Xyoo no, ntxiv rau qhov thib ob E-Huang River hla (Yanji Yangtze River Choj thiab nws qhov kev sib txuas), uas twb tau pib lawm, Hubei Communications Investment Group kuj tseem tab tom tsim 4 lub Yangtze River Choj tib lub sijhawm. Jingzhou Guanyin Temple Yangtze River Choj thiab Jingzhou Libu Yangtze River Highway thiab Railway Choj yog ob lub choj ob-dej; kev tsim kho ntawm Zhijiang Bailizhou Yangtze River Choj yuav hais lus zoo rau keeb kwm ntawm kev hla tus dej rau ntau txhiab xyoo.

Cov Kws Tshaj Lij Xyuas

Qiaodu txav ntawm "kev nkag tau yooj yim" mus rau "kev tsim kho tshiab"

Qhov thib ob E-Huang River Crossing Channel (Yanji Yangtze River Choj) txuas Huanggang thiab Ezhou. Nws yog ib qho tseem ceeb txhawb nqa project rau lub hauv paus logistics thoob ntiaj teb nrog Ezhou Huahu Tshav Dav Hlau ua lub hauv paus. Nws yuav pab Hubei "dual hub" txoj kev npaj thiab txhim kho lub tsheb thauj mus los. Nws yog qhov tseem ceeb heev los muab kev ua si tag nrho rau cov txiaj ntsig ntawm lub hauv paus logistics hub thiab txhawb kev txhim kho zoo ntawm kev koom ua ke ntawm Wu, Hubei thiab Huanghua.

Lub ntsiab lus ntawm 1860 meters thiab ib qho hla tus dej, plaub lub xov hlau tseem ceeb tshiab, qhov sib txawv sag, ob txheej tsheb hlau truss suspension choj scheme, txhua yam qhia txog lub zog tseem ceeb ntawm Wuhan ua lub peev txheej tsim choj. Cov xov xwm zoo yog tias nrog kev txhim kho ntawm cov khoom siv, thev naus laus zis thiab cov tswv yim, Hubei Bridge Construction Corps tau koom nrog kev tsim kho ntau lub choj zoo tshaj plaws hauv ntiaj teb, thiab tau daws cov teeb meem tsim choj thoob ntiaj teb xws li "dej tob", "loj" thiab "kev kub ceev".

Lub ntiaj teb tsim cov choj kom pom Tuam Tshoj, thiab Tuam Tshoj tsim cov choj kom pom Wuhan. Qhov tseem ceeb dua yog tias Yanji Yangtze River Choj qhia txog kev tshawb nrhiav los ntawm "kev nkag mus tau yooj yim thiab yooj yim" mus rau "kev sib koom tes tsim kho tshiab", uas yog qhov tseem ceeb rau kev txhawb nqa kev txhim kho ntawm lub ntiaj teb ultra-loj-span suspension choj thev naus laus zis, ntxiv polishing lub npe daim npav ntawm Tuam Tshoj txoj kev tsim choj, thiab paub txog lub tswv yim ntawm kev tsim lub teb chaws muaj zog hauv kev thauj mus los. tseem ceeb.
