Ib ntus Choj Bailey Structure

• Modular thiab Standardized: Tag nrho cov khoom (trusses, beams, choj lawj, connectors) muaj standardized specifications, zoo li "bridge tsev blocks," kom ntseeg tau siab interchangeability.
• Kev sib dhos nrawm: Tsis tas yuav tsum muaj cov cuab yeej tshwj xeeb loj; erection thiab dismantling tuaj yeem ua tiav sai sai uas siv cov khoom siv tes ua haujlwm thiab lub teeb.
• Strong Structural Integrity thiab High Load-Bearing Capacity: Cov qauv truss zoo faib cov loads. Qhov ncua sij hawm thiab lub peev xwm thauj khoom tuaj yeem hloov kho tau yooj yim los ntawm kev nce tus naj npawb ntawm truss seem (ib kab, ob kab, kab peb kab) thiab cov txheej txheem (ib txheej, ob txheej, peb txheej).

Wide Adaptability:

• Flexible Span: Los ntawm ob peb metres mus rau ntau pua metres (kev xav, qhov siab tshaj plaws tuaj yeem ncav cuag 120 meters).
• Kev sib txawv Load: Los ntawm kev sib txawv ntawm cov qauv tsim, nws tuaj yeem ua tau raws li qhov yuav tsum tau ua ntawm cov neeg taug kev, lub teeb tsheb, cov tso tsheb hlau luam hnyav (loj thauj khoom -50 qib), thiab cov khoom siv loj.
• Terrain Adaptability: Tsim nyog rau ntau yam xwm txheej xws li dej ntws, canyons, kho choj, thiab kev tsim kho ib ntus.
• Reusability thiab Economic Efficiency: Cheebtsam tuaj yeem raug tshem tawm thiab rov siv tau ntau zaus, ua rau cov nqi qis qis, ua rau nws tsim nyog rau cov haujlwm ib ntus thiab kev cawm thaum muaj xwm txheej ceev.

• Bailey Panels (Truss Units): Cov tub ntxhais thauj khoom -cov kabmob, siv cov qauv welded steel truss. Cov qauv muaj xws li hom 321 (3m ib lub vaj huam sib luag ntev) thiab hom 200 (2m ib lub vaj huam sib luag ntev). Txuas los ntawm tus pins lossis bolts, lawv tuaj yeem ua ke los ua cov kab teeb ci tseem ceeb ntawm qhov sib txawv, tsim cov ntsiab lus ntawm cov khoom siv thauj khoom-cov kabmob muaj peev xwm.
• Crossbeams: Transverse kev them nyiaj yug Cheebtsam, spanning ntawm lub sab sauv chords ntawm lub Bailey panels. Lawv txhawb nqa tus choj lawj system thiab sib npaug ntawm cov khoom thauj mus rau cov kab teeb loj. Lawv feem ntau yog ua los ntawm I-beams lossis channel steel, nrog qhov sib txawv ntawm qhov sib txawv raws li qhov yuav tsum tau ua.
• Longitudinal Beams: Longitudinal txuas Cheebtsam, nteg nyob rau hauv ntev ntawm tus choj saum toj no transverse beams, ntxiv distributing tus choj lawj load thiab muab ib tug du nto rau tus choj lawj pavement.

• Choj Deck Units: Cov qauv saum npoo uas ncaj qha bears lub tsheb thauj khoom. Raws li qhov yuav tsum tau ua, nws tuaj yeem siv los tiv thaiv- cov hlau nplaum, cov pavement pob zeb, lossis ob qho tib si ua ke. Qhov saum npoo feem ntau yog nqes los xyuas kom cov dej ntws tawm; hauv qee qhov xwm txheej, tiv thaiv- cov qauv nplawm lossis tiv thaiv- cov khaubncaws sab nraud povtseg ntxiv.
• Txuas thiab ruaj khov Cheebtsam: suav nrog tus pins, bolts, tiv thaiv - lateral braces, thiab txiv neej hlua. Pins yog cov tseem ceeb fasteners rau Bailey choj vaj huam sib luag kev sib txuas thiab yuav tsum tau ua raws nraim kom hloov cov shear quab yuam. Kev tiv thaiv - lateral braces thiab txiv neej ropes txhim khu lub lateral stability ntawm tus qauv, tiv thaiv overturning thaum lub sij hawm erection los yog siv.
• Lub hauv paus thiab kev txhawb nqa: Lub substructure txhawb nqa tag nrho cov qauv. Hauv cov xwm txheej ib ntus, cov kaus mom pob zeb, cov pob zeb dhuav, lossis cov kob - cov hauv paus rov qab tuaj yeem siv tau. Cov kev txhawb nqa yog nyob nruab nrab ntawm lub hauv paus thiab qhov kawg ntawm cov kab teeb tseem ceeb, kom ntseeg tau tias kev thauj mus los thaum ua haujlwm me me.

• Kev Pabcuam Thaum Muaj Xwm Ceev: Thaum cov choj raug puas tsuaj los ntawm kev puas tsuaj xws li dej nyab thiab av qeeg, cov kev taug kev ib ntus tuaj yeem tsim kho sai sai kom ntseeg tau tias kev thauj mus los ntawm cov neeg cawm siav thiab cov khoom siv.
• Kev khiav tsheb mus ib ntus rau kev tsim kho cov phiaj xwm: Thaum lub sijhawm txhim kho txoj kev thiab nthuav dav, lossis kev rhuav tshem cov choj thiab kev tsim kho, cov choj ib ntus tuaj yeem tsim kho kom muaj kev hla ntawm cov tsheb thiab cov neeg taug kev.

• Kev Txhawb Kev Tsim Kho: Raws li kev txhawb nqa ib ntus rau kev teeb tsa ntawm cam khwb cia- hauv - qhov chaw cov kab teeb ci thiab cov kab hluav taws xob precast, nws yog qhov tsim nyog rau kev ua haujlwm overhead thaum lub sij hawm tsim choj.
• Kev nkag mus ib ntus hauv thaj chaw deb: Hauv thaj chaw roob roob, thaj chaw mining, thiab lwm thaj chaw uas muaj kev thauj mus los tsis yooj yim, cov choj ib ntus tuaj yeem tsim ua kom tau raws li kev tsim kho lossis kev xav tau kev thauj mus los txhua hnub; lawv tuaj yeem rhuav tshem thiab rov ua dua tom qab qhov project tiav.
