Thaum Lub Yim Hli 15, tus choj hlau ntawm Beijing-Shanghai Railway hla ntawm txoj kev nkag ntawm Jinan Thermal Power Group, uas tau tsim los ntawm lub tuam txhab, tig du thiab tig 74 degrees clockwise hauv huab cua kom ua tiav "zoo nkauj tig", tso. lub hauv paus ruaj khov rau kev ua tiav thiab qhib tag nrho cov kab raws li tau teem tseg.
Nws tsuas yog siv sijhawm 180 hnub txij li qhov pib ntawm qhov project mus rau qhov ua tiav ntawm qhov kev sib hloov, uas tau tsim cov ntaub ntawv tshiab rau lub sijhawm tsim kho ntawm steel kem girder rotating choj hauv Shandong xeev.
Qhov chaw tsim kho ntawm Beijing-Shanghai railway overpass project yog nyob rau hauv Gu Yunhu Street, Changqing District, Jinan City. Lub kaum sab xis ntawm tus choj thiab txoj kab nruab nrab ntawm Beijing-Shanghai Railway yog 72 degrees, thiab tus choj lawj yog traizoid, 150 meters ntev thiab 26.237 meters dav. Kev sib hloov siv tau siv sijhawm 60 feeb, thiab tus choj tig 74 degrees clockwise thiab thaum kawg tau tshwm sim. Lub thawv steel girder ntawm tus choj rotating muaj cov yam ntxwv ntawm qhov sib txawv ntawm qhov dav, qhov dav thiab qhov hnyav, thiab lwm yam. Vim yog cov kev txwv ntawm kev thauj mus los, feem ntau ntawm cov thawv steel yog sib sau ua ke thiab welded rau ntawm qhov chaw, uas yog qhov nyuaj rau kev tsim thiab yuav tsum tau siab. tshuab.
Txhawm rau kom ntseeg tau tias "kev sib hloov raug" ntawm tus choj rotating, qhov project department ntawm lub tuam txhab, nyob rau hauv kev taw qhia ntawm Tuam Tshoj Railway No. 10 Bureau, tus tswv tsev thiab lub tuam txhab, tau ua ntau qhov chaw soj ntsuam, thiab ua ib tug 11 degree. kuaj kev sib hloov ntawm tus choj rotating ua ntej rau lub Yim Hli 14, muab qhov tsis raug rau qhov kev sib hloov thiab ua kom ntseeg tau tias qhov kev ua haujlwm ntawm kev sib hloov tau ua tau raws li qhov yuav tsum tau ua ntawm lub cev rotating.
Txij li thaum pib ntawm qhov project, lub tuam txhab qhov project department tau ua tag nrho cov kev npaj thiab kev xa tawm, tsim cov phiaj xwm txhawb kev tsim kho, tau xaiv cov neeg tshwj xeeb los ua lub luag haujlwm rau cov ntawv tshaj tawm txhua hnub ntawm kev txhim kho kev txhim kho, txiav txim siab ua tiav tib hnub, tas li innovate los daws qhov teeb meem. technical teeb meem nyob rau hauv cov txheej txheem ntawm kev sib hloov, thiab ua tau zoo tej yaam num.
Txoj kev sib hloov ntawm tus choj steel hla Beijing-Shanghai railway overpass ntawm txoj kev nkag mus rau hauv cov nroj tsuag ntawm Jinan Thermoelectric Group qhia lub tuam txhab kev ua haujlwm lub zog thiab kev tsim kho tshiab muaj peev xwm hauv kev ua haujlwm ntawm choj kev sib hloov kev pabcuam. Lub tuam txhab yuav txuas ntxiv ua raws li lub luag haujlwm ntawm lub tuam txhab "tsim cov khoom lag luam zoo thiab cov haujlwm zoo", thiab txuas ntxiv tshawb nrhiav thiab siv cov thev naus laus zis tshiab thiab cov txheej txheem tshiab los pab txhawb kev txawj ntse thiab lub zog rau kev tsim kho vaj tse hauv teb chaws thiab kev lag luam hauv cheeb tsam nrog ntau dua. scientific thiab kev pabcuam zoo.
