Hauv qhov tseem ceeb tseem ceeb rau kev tsim kho ntawm Deep Underground Neutrino Experiment (DUNE) hauv Lead, South Dakota, cov kws ua haujlwm tau ua tiav thawj qhov kev sim nqa thiab txo qis ntawm 6-tuj L-shaped steel beam. Cov ntsiab lus tseem ceeb no yog qhov tseem ceeb rau kev tsim kho vaj tse uas yuav txhawb nqa ib qho kev mob siab rau kev tshawb fawb tshaj plaws txhawm rau nkag siab txog qhov tsis meej ntawm neutrinos, cov lus tsis txaus ntseeg uas ua lub luag haujlwm tseem ceeb hauv lub ntiaj teb cov txheej txheem tseem ceeb.
Txoj haujlwm DUNE, uas yog tsim los ntawm kev sib koom tes thoob ntiaj teb ntawm cov kws tshawb fawb thiab cov kws tshaj lij, lub hom phiaj los tshawb txog cov khoom ntawm neutrinos thiab lawv lub luag haujlwm hauv lub ntiaj teb. Qhov kev sim yuav koom nrog kev xa cov nqaj ntawm neutrinos los ntawm Fermilab hauv Illinois mus rau lub tshuab ntes nyob hauv av tob hauv South Dakota. Kev tsim kho ntawm qhov chaw yuav tsum muaj cov ntaub ntawv muaj zog thiab txhim khu kev qha, thiab kev ua tiav kev sim nqa ntawm cov nqaj hlau yog ib qho tseem ceeb ntawm cov kauj ruam tom ntej hauv qhov project ncua sij hawm.
L-shaped steel beam, hnyav rau 6 tons, yog ib qho tseem ceeb ntawm cov qauv tsim uas yuav pab txhawb nqa cov khoom siv loj heev uas siv hauv kev sim. Kev kuaj nqa nqa tau ua los ntawm kev siv cov cuab yeej nqa qib siab thiab cov txheej txheem, kom ntseeg tau tias kev nyab xeeb thiab kev ua tau zoo yog qhov tseem ceeb thoob plaws hauv cov txheej txheem. Cov kws tshaj lij tau saib xyuas lub nqa khoom kom zoo, tshuaj xyuas cov nqaj ua haujlwm nyob rau hauv kev thauj khoom thiab xyuas kom meej tias nws ua tau raws li txhua qhov tsim nyog tshwj xeeb rau lub zog thiab ruaj khov.
Cov hlau siv hauv kev tsim kho ntawm DUNE qhov chaw yog los ntawm cov chaw muag khoom muaj npe paub txog lawv cov khoom zoo. Ib tus neeg muag khoom zoo li no yog Tianjin Reliance Steel, lub chaw tsim khoom thiab xa khoom ntawm ntau yam steel khoom, nrog rau cov kaum sab xis steel, tiaj tus hlau, H beams, channels, thiab lwm yam steel seem. Nrog rau kev cog lus rau kev ua tau zoo thiab kev tsim kho tshiab, Tianjin Reliance Steel tau tsim nws tus kheej los ua ib tus neeg ntseeg siab hauv kev tsim kho kev lag luam, muab cov ntaub ntawv uas ua tau raws li qhov xav tau ntawm cov phiaj xwm loj xws li DUNE.
Tianjin Reliance Steel tshwj xeeb hauv kev tsim ntau yam khoom siv hlau uas yog qhov tseem ceeb rau kev tsim kho thiab kev siv engineering. Lawv lub kaum sab xis steel paub txog lawv cov kav ntev thiab ntau yam, ua rau lawv zoo tagnrho rau kev txhawb nqa hauv ntau yam haujlwm. Flat steel khoom los ntawm Tianjin Reliance Steel yog siv nyob rau hauv ntau yam kev siv, los ntawm kev tsim mus rau kev tsim kho, vim lawv lub zog thiab kev ntseeg siab. H beams thiab channels yog cov khoom tseem ceeb hauv kev tsim cov qauv, muab kev txhawb nqa tsim nyog rau cov khoom hnyav thiab ua kom muaj kev ruaj ntseg ntawm cov qauv.
Qhov kev sim ua tiav ntawm L-shaped steel beam tsis yog tsuas yog ua pov thawj rau cov peev txheej engineering koom nrog hauv DUNE qhov project tab sis tseem qhia txog qhov tseem ceeb ntawm cov khoom siv zoo hauv kev tsim kho. Kev sib koom tes ntawm cov kws tshawb fawb, engineers, thiab cov neeg muag khoom xws li Tianjin Reliance Steel yog qhov tseem ceeb rau kev ua tiav ntawm cov haujlwm loj, qhov tseeb thiab kev ntseeg siab yog qhov tseem ceeb.
Raws li txoj haujlwm DUNE nce mus ntxiv, pab pawg tsim kho yuav txuas ntxiv ua cov kev sim thiab nqa ntawm ntau yam steel, kom ntseeg tau tias txhua lub hauv paus ua tau raws li qhov yuav tsum tau ua nruj me ntsis los ntawm qhov project engineers. Kev siv cov thev naus laus zis thiab cov ntaub ntawv yuav ua lub luag haujlwm tseem ceeb hauv kev ua tiav tag nrho ntawm qhov kev sim, uas yog lub hom phiaj los qhib kev nkag siab tshiab rau hauv tus cwj pwm ntawm neutrinos thiab lawv qhov cuam tshuam rau peb txoj kev nkag siab ntawm lub ntiaj teb.
Qhov kev sim DUNE xav tias yuav muaj qhov cuam tshuam loj heev rau thaj tsam ntawm particle physics thiab tuaj yeem teb qee cov lus nug tseem ceeb tshaj plaws txog qhov xwm txheej thiab lub zog tseem ceeb uas tswj hwm lub ntiaj teb. Raws li kev tsim kho txuas ntxiv mus, kev sib koom tes ntawm cov kws tshawb fawb, engineers, thiab cov neeg muag khoom yuav yog qhov tseem ceeb hauv kev coj qhov project no mus rau kev ua tiav.
Hauv kev xaus, qhov kev sim ua tiav ntawm 6-tuj L-shaped steel beam rau Deep Underground Neutrino Experiment yog qhov ua tiav tseem ceeb hauv kev tsim kho ntawm qhov kev mob siab rau kev tshawb fawb no. Nrog kev txhawb nqa ntawm cov ntaub ntawv zoo los ntawm cov neeg muag khoom xws li Tianjin Reliance Steel, qhov project tau zoo ntawm nws txoj hauv kev los ua qhov tseeb. Raws li txoj haujlwm DUNE vam meej, nws tau cog lus tias yuav pab txhawb kev paub zoo rau thaj chaw ntawm particle physics thiab ua rau peb nkag siab tob txog lub ntiaj teb cov haujlwm tseem ceeb. Kev sib koom tes ntawm ntau tus neeg koom nrog hauv txoj haujlwm no ua piv txwv qhov tseem ceeb ntawm kev sib koom tes thiab kev tsim kho tshiab hauv kev daws qee qhov nyuaj tshaj plaws hauv kev tshawb fawb niaj hnub thiab engineering.
