Cov ntsiab lus tseem ceeb rau kev teeb tsa tseem ceeb ntawm Bailey Truss Choj

Tom qab npaj cov khoom xws li Bailey panels, cov theem tseem ceeb ntawm kev teeb tsa pib, qhov kev tswj xyuas qhov tseeb thiab cov cuab yeej ua haujlwm tseem ceeb tshwj xeeb.

Lub ntsiab choj erection txoj kev: Cov kev xaiv ntawm txoj kev yuav tsum tau yoog rau hauv zos tej yam kev mob. Txoj kev siv ntau tshaj plaws yog "cantilever push-tawm txoj kev," uas ua rau kev tsim kho choj sai thiab nyab xeeb yam tsis tas yuav muaj cov khoom nqa loj. Thaum qhov chaw tso cai thiab cov khoom tuaj yeem muab faib ua cov chav loj dua, "tag nrho-span lifting method" yuav raug saws. Nyob rau hauv txoj kev dej los yog gorges uas ruaj lem tsis tuaj yeem ntsia tau, "txoj kev thauj mus los thiab erection" los yog cable- nyob twj ywm lifting system tuaj yeem xaiv tau.

Cov ntsiab lus tseem ceeb ntawm kev sib txuas:
Txhim kho chord installation: Xyuas kom lub installation ntawm reinforced chords, nrog rau hauv zos reinforcement ntawm cov chaw txhawb. Thaum lub sij hawm sib dhos, ua tib zoo saib xyuas qhov sib txawv ntawm cov chords sab sauv thiab qis (cov chord sab sauv feem ntau yog 2 hli ntev dua) los tsim lub pre-camber uas tiv thaiv deflection hauv qab load.

Bére tus pin txuas: Bére panels txuas nrog siv tus pins; kev tawm tsam lossis yuam lawv raug txwv nruj heev. Yog hais tias lub qhov misalignment ntau tshaj 1 hli, qhov ua rau yuav tsum tau txheeb xyuas thiab lub qhov yuav tsum tsis txhob yuam kom loj. Tom qab txhim kho tag nrho cov pins, kev ruaj ntseg xauv pins yuav tsum tau ua kom zoo.

Torque thiab Anti- loosening: Tag nrho cov kev sib txuas bolted yuav tsum tau nruj siv lub torque ciaj ntswj nyob rau hauv ob kauj ruam - pib zawm thiab zaum kawg zawm- kom ntseeg tau tias lub torque tau raws li qhov yuav tsum tau tsim.
