Bailey choj ua kom cov txheej txheem kho

Bailey choj txais cov txheej txheem ua ntej kev ntxhov siab, yog li ntau txoj kev tsim kho yam tsis muaj kev txhawb nqa uas yav tas los haum rau steel choj erection kuj tseem siv tau rau tus choj pob zeb no, thiab nws cov nqi txo qis, thiab lub suab nrov ntawm kev tsav tsheb me me. Beret Choj yuav tsum nruab kab kab pheeb ces kaum ntawm lub truss beam nyob rau hauv pem hauv ntej seem, thiab nruab sab sauv beams tom qab ntsug rods nyob rau hauv pem hauv ntej kawg ntawm ob trusses. Cov kab hluav taws xob sab saud yuav tsum tau maj mam tuav ntawm lub nqaj jig thiab tsis nruj kom txog thaum lub kab pheeb ces kaum ntawm lub nqaj raug teeb tsa.

Txhim kho peb lub trusses, thiab nruab lub cua khi pas nrig rau ntawm ib daim truss, thiab nruab kab pheeb ces kaum ntawm lub nqaj ntawm ob lub truss pieces, thiab ces voj voog nyob rau hauv lem mus rau nruab lub qhov ntswg ncej. Tag nrho ntawm plaub truss daim yuav tsum tau muab ntsia raws li lub qhov ntswg ncej. Nyob rau hauv tus txheej txheem ntawm traction, hais kom ua, cov kauj ruam yuav tsum zoo ib yam thiab kev khiav hauj lwm kev sib koom tes yuav tsum ua kom tiav. Kev ua haujlwm ntawm cov menyuam thiab tus choj yuav tsum tau kuaj xyuas txhua lub sijhawm. Yog tias muaj ib qho, kev ua haujlwm yuav tsum raug tso tseg tam sim ntawd thiab qhov teeb meem yuav tsum tau daws ua ntej txuas mus ntxiv mus.

Kev saib xyuas ntawm Bailey thav duab yog nyob ntawm qhov muab tub lim, nrog rau cov khoom siv lub cev ntawm cov khoom tseem ceeb ntawm cov khoom, suav nrog cov polymer, thiab nyob ntawm seb ob qho khoom sib xyaw ua ke, cov khoom tuaj yeem ua pob tshab lossis tsis pom tseeb. Nyob rau hauv lub teeb curing polyurethane, aluminium hydroxide yog pob tshab rau lub teeb, yog li nws tuaj yeem ua kom cov txheej txheem kho kom zoo, yog li cov kav dej sab nraum zoov feem ntau yog xim dub, feem ntau yog siv cov pa roj carbon dub filling kom txo qhov ceev ntawm lub teeb aging.

Ib txoj kab ntev ntev yog ntsia rau ntawm cov kauj ruam saum toj kawg nkaus ntawm abutment pier kem, thiab lub lawj steel yog tsau rau ntawm txoj kab sib txuas ntev, ib txoj kab xaim xaim xaim yog tsau rau hauv qab ntawm txoj kab sib txuas ntev, thiab lub phaj txhawb nqa tau nruab rau ntawm hauv qab ntawm lub transverse faib beam, thiab cov phaj txhawb yog tsau nyob rau sab saum toj ntawm seem steel inclined kev txhawb nqa txuas, thiab hauv qab ntawm seem steel inclined kev txhawb nqa txuas yog tsau rau ntawm lub hauv paus pier.
