1 Bailey choj tivthaiv
2 tau txais lub hwj huam xovxwm los ntawm cov girder
3 yuav pab tau rau tus choj nov hauv Abutment
Nws yog siv rau cov teev choj lub rooj zaum, thiab distributing tusyees lub load rau groundwork. Tsab ntawv 1, 2, & 3 ntawv ntawm lub txaj phaj sawv feem tus choj lub rooj zaum chaw kab luag hauj lwm ntawm ib kab, dual-leej thiab triple-leej. Nyob rau sab nraud ntawm lub txaj phaj yog tus ntawv txoj hauj lwm qhov chaw kab ntawm tus choj luv li siab xav.
Bailey choj kom ib yam kev tshwj xeeb los sis cov khoom hnyav rau siv, tus choj hais nws me txaus nqa ntawm, thiab tus choj yog muaj zog txaus los muaj. Qhov ntawd yog ib tug piv txwv zoo kawg thiab cov tub rog engineering.

Choj vaj huam sib luag rau 200 compact: tus vaj huam sib luag rau 200 choj compact yeej zoo xws lub vaj huam sib luag rau 100 compact choj ntawm lawv lub zog. Qhov txawv yog nws qhov siab muaj vaj huam sib luag rau 2.134m. Nws ua hauj lwm cov pob qij txha Chords qhov cuab lub zog thiab lub pob qij txha ntawm panels alternating peb. Hom no yuav txo tau inelastic los ntawm cov oversized pinholes deformation. Siv txoj kev arch tos ntxiv thiab ntov deflection mid-siab kawg thiab tab mus rau ib tug kawm ntawv loj. Ntsia liaj qhov rooj txuas nrog Cheebtsam siv lub orienting - lub tes tsho fixing txoj kev kom cov neeg uas sib txuas. Shear yog tsim nyob rau hauv orienting tsho thiab nro yog tsim nyob rau hauv bolts, uas ua rau kom pab txoj hauj lwm ntawm lub bolts thiab kev xyuam xim rau cov txuas hniav vaj huam sib luag. Cua resistant brace txim siab los yog puas hom thiab txuas nrog transom/girders lug txhim khu stability zuag qhia tag nrho cov kev txuas hniav vaj huam sib luag.
Ib sab ntawm ncej braced thiab panels tsau los ntawm bridging sij kom tus choj tseem sab dabtsi yog khoov. Tom qab lub erection, yuav muaj ib tug muaj menyuam mus saib ntawm arched kawm ntawv pem lub siab txog ntawm tus choj. Besides nws yuav tsum assembled rau hauv ib txoj kab txuas hniav. Choj vaj huam sib luag rau 200 compact kuj raug assembled ua dua zaum ob txoj kab choj, yog li nws broadens nws ntau yam ntaub ntawv. Nws yog tsim rau cov load designs HS-15, HS-20, HS-25 thiab pedrail-50 thiab lwm yam.
