Lub Al Wasl Plaza yuav muaj cov hlau tseem ceeb - qauv dome- ua kom zoo nkauj hauv qhov ntsuas - uas yog qhov chaw nruab nrab ntawm Expo 2020 Dubai.
Sau nqi raws li "Festival of Minds," Expo 2020 Dubai yog thawj lub Ntiaj Teb Expo tuav hauv Middle East, Africa, thiab South Asia cheeb tsam.
Spanning tag nrho Al Wasl Plaza, lub dome nta ib qho kev sib tw lattice qauv uas zoo nkaus li rau thauj tog rau nkoj steel ruaj khov ntawm lub plawv ntawm Expo. Sawv ntsug 67.5 meters siab thiab 130 meters dav, lub dome yog tsim los ntawm 13,600 meters siab -lub zog structural steel (Q345/SM490A sib npaug)-tag nrho 2,265 metric tons. Nws semi{12}}pob tshab nto integrates immersive projection yaam puab paub, muab panoramic views ntawm ob sab hauv thiab sab sauv.
"Qhov no yog cov txheej txheem tsim khoom tshwj xeeb uas xav tau kev tsim ntau dua 1,000 tus neeg nkhaus steel ntu thiab 17,000 steel brackets, tag nrho cov welded ua ke los tsim tus qauv Expo tus qauv tsim qauv," sau tseg rau pawg neeg ua haujlwm.
Lub Expo tus tswv txoj kev npaj muaj kev cuam tshuam loj heev los ntawm lub ntsiab lus "Kev Sib Txuas Lub Siab, Tsim Lub Neej Yav Tom Ntej," nrog rau peb lub sub- cov ntsiab lus: Lub Sijhawm, Mobility, thiab Sustainability- txhua tus nrog thaj chaw tshwj xeeb pavilion. Al Wasl Plaza zaum ntawm lub tsev kawm ntawv hauv tsev kawm ntawv, txuas rau peb cheeb tsam thematic, haum rau ntau tshaj 10,000 tus neeg tuaj saib, thiab ua haujlwm ua 360-degree projection platform rau cov xwm txheej hmo ntuj.
Ahmed Al Khatib, Tus Lwm Thawj Coj Loj ntawm Kev Txhim Kho Vaj Tsev & Kev Xa Khoom rau Expo 2020 Dubai, saib xyuas qhov chaw npaj tswv yim thiab xa cov khoom siv rau pej xeem, kev tsim vaj tsev, txoj kev, kev sib txuas, thiab kev thauj mus los.
"Peb tau muaj kev sib tw tsim thoob ntiaj teb rau lub dome, feem ntau los qhia txog qhov tseem ceeb ntawm Al Wasl Plaza. 'Al Wasl' txhais tau tias 'kev sib txuas' hauv Arabic thiab yog Dubai lub npe qub - yog li lub npe no muaj lub ntsiab lus tshwj xeeb rau kuv, "Al Khatib piav qhia.
"Peb cia siab tias qhov Expo no muab qhov kev paub tsis nco qab rau cov neeg tuaj saib thiab tsim cov hniav nyiaj hniav kub- zoo li thaj chaw hauv plawv ntawm lub xaib los tuav lub rooj sib tham qhib thiab txhua qhov xwm txheej loj. Ib txhij, cov qauv no yuav txuas ntxiv tsim txiaj ntsig raws li ib feem ntawm Expo tus tswv txoj kev npaj- ua haujlwm ruaj khov, tam sim no thiab yav tom ntej."
Qhov kev sib tw tsim los ntawm Chicago-raws li Adrian Smith + Gordon Gill Architecture (AS + GG) tau txais kev tshoov siab los ntawm Expo lub cim tshiab thiab lub nplhaib kub tau pom ntawm Sarouq Al Hadeed archaeological site hauv Dubai suab puam.
Precision Steel Fabrication: Los ntawm Seamless Tubes mus rau Curved Sections
Nruab nrab- zaus dabtsi yog khoov ntawm seamless steel raj tau ua tiav hauv tebchaws Poland thiab Czech koom pheej, thaum lub dome daim ntawv cog lus steel qauv tau txais txiaj ntsig rau Cimolai Rimond Middle East General Contracting, UAE-Italy kev sib koom ua lag luam.
"Tau kawg, qhov no yog mega - qauv," Al Khatib sau tseg. "Cov txheej txheem kev txhawb nqa siv siab- lub zog seamless steel raj nrog 500mm txoj kab uas hla (tsim los ntawm Q345 / Q355 cov qauv carbon steel)-yog tias tau tso tseg- mus rau- kawg, lawv yuav ncav cuag 13.6 mais."
"Qhov no yog cov txheej txheem tsim khoom tshwj xeeb uas yuav tsum tau tsim ntau dua 1,000 tus neeg nkhaus steel ntu thiab 17,000 steel brackets, tag nrho cov welded ua ke los ua tus Expo tus qauv tsim qauv. Sawv hauv semi-pob tshab dome plaza, cov neeg tuaj saib tuaj yeem saib thiab pom qhov sib txawv steel lattice."
Cov 175,000 steel rings nyob rau hauv txawv qhov ntev yog infilled nrog PTFE-coated fiberglass ntaub. Ntau yam ntaub ntawv raug sim siv qhov projections tiag tiag ntawm cov qauv ntu ntawm lub moj khaum los xyuas kom meej cov duab zoo.
"Yuav kom txhim kho cov hlau lattice, peb kuj xav tau 1,200 tons ntawm cov qauv hlau ib ntus (Q235 / Q345) raws li kev txhawb nqa thaum lub sijhawm tsim kho," Al Khatib txuas ntxiv. "Hauv kev xyaum, peb tau siv lub khoos phis tawj tsim qauv software kom meej meej thiab paub meej tias txhua theem kev tsim kho. Txhua lub qhov rais installation tau nruj heev-txhua qhov kev txwv tsis pub muaj peev xwm ua rau muaj kev cuam tshuam domino ntawm tag nrho lub sijhawm."

Lub dome yog qhov kawg tsim tseem ceeb ntawm lub tsev kawm ntawv Expo. Nws lub ru tsev qhib rau saum ntuj, ua kom cov neeg tuaj saib kev nplij siab thaum muab kev tiv thaiv huab cua.
"Lub dome tsim suav nrog ntau cov thev naus laus zis siab heev, suav nrog kev txiav -ntug laser projectors, 2,700 LED fixtures, thiab 25 kilometers ntawm cabling," Al Khatib ntxiv.
Kev tsim kho hauv tsev kawm theem pib tau teem sijhawm ua tiav thaum Lub Kaum Hli 2019, tso cai rau kev sim txaus thiab sijhawm npaj rau kev qhib loj thaum Lub Kaum Hli 2020.
Expo 2020 Dubai tau khiav txij lub Kaum Hli 20, 2020, txog rau lub Plaub Hlis 10, 2021. Tshaj tawm -Expo, lub plaza txuas ntxiv ua lub vaj ntuj thiab ntau yam - lub hom phiaj rau cov xwm txheej, kev paub, thiab kev sib sau hauv zej zog. Nws ua haujlwm raws li kev sib koom ua ke hauv nroog loj hlob nrog kev sib txuas zoo heev - nthuav dav Expo lub hom phiaj ntawm kev sib txuas lus, kev tsim, thiab kev tsim kho tshiab.
Ahmed Al Khatib ntseeg tias: "Cov chaw pej xeem zoo li Al Wasl Plaza yog qhov tsis tau muaj dua nyob hauv lub ntiaj teb thiab yuav txhawb nqa cov neeg tuaj saib thoob plaws ntiaj teb. Txhua tus yuav zoo siab los ua qhov chaw uas muaj kev sib koom ua ke ntawm xwm thiab thev naus laus zis tshiab- thiab peb vam tias nws yuav ua tiav zoo heev."
>Kev Pom Kev Xaiv Cov Khoom Siv: Rau cov qauv tsim vaj tsev iconic uas xav tau kev tsim khoom, kev tiv thaiv corrosion, thiab ntev - lub sij hawm durability nyob rau hauv hnyav huab cua:
- Cov qauv carbon steel (Q345 / Q355 / SM490A / ASTM A572): Zoo tagnrho rau cov ntu nkhaus, seamless raj, thiab thawj framing
- Seamless steel tubes (Q345 / Q355 / ASTM A106): Qhov tseem ceeb rau siab -load txhawb lub moj khaum nrog precision dabtsi yog khoov yuav tsum
