Beam Bridges
Lub nqaj choj yog ib qho yooj yim tshaj plaws thiab pheej yig tshaj tus choj tsim. Beam txuas hniav yog hom nrov tshaj plaws ntawm kev tsim choj hauv UK vim lawv qhov yooj yim hauv kev tsim.

Ib tug nqaj choj yuav muaj xws li ob peb kab teeb uas khiav nyob rau hauv parallel los txhawb lub lawj saum toj no, feem ntau hu ua "tsuas yog kev txhawb nqa" qauv, vim tsis muaj kev hloov ntawm kev ntxhov siab raws li pom nyob rau hauv lwm hom kev tsim choj.

 

A beam bridge is one of the simplest and most cost-effective bridges to build. Beam bridges are the most popular type of bridge construction in the UK due to their simplicity in design.

 

Integral Beam Bridges
Integral beam choj yog ib txoj hauv kev niaj hnub tsim rau cov kab teeb tsa ib txwm siv uas suav nrog cov kab hluav taws xob txuas thiab txuas txuas ntxiv. Cov kev txhim kho hauv kev tsim kho thiab kev tsim cov nqaj hlau prefabricated tau ua kom tshem tawm cov teeb meem txij nkawm nyob ib puag ncig tus choj bearings thiab cov pob qij txha expansion.

Lub substructure thiab superstructure ntawm ib qho tseem ceeb choj beam yog tsim tsis muaj kev sib koom tes ntawm spans los yog ntawm spans thiab abutments. Yog li ntawd, lub superstructure thiab abutments ua raws li ib tug structural units uas ua hauj lwm zoo rau luv luv mus rau nruab nrab span txuas hniav.

Cantilever Choj
Tus choj cantilever yog tsim los siv cantilever, cov qauv uas ua haujlwm horizontally thiab tau txais kev txhawb nqa ntawm ib kawg nkaus xwb. Yog tias koj tsis paub txog lub hauv paus ntsiab lus ntawm cantilever, kos duab lub nkoj dhia dej txhawb nqa ntawm ib qho kawg.

Ib tug cantilever choj yog tsim los siv pillars ruaj ntseg anched rau hauv av. Cov qauv tsim tawm sab nraud los ntawm txhua tus ncej, nrog cov kab kab rov tav feem ntau txhawb nqa siv kab pheeb ces kaum.

Arch Choj

 

Arch txuas hniav yog incredibly muaj zog thiab ncaj choj uas tau siv rau ntau txhiab xyoo.

Cov choj no tau qhia los ntawm cov neeg Loos thiab tseem nrov niaj hnub no; Txawm li cas los xij, nyob rau lub sijhawm tam sim no, arch txuas hniav yog tsim los ntawm pob zeb es tsis yog cov pob zeb thiab cib siv keeb kwm.

Kev tsim kho ntawm tus choj arch pom abutments ntawm txhua qhov kawg zoo li tus nkhaus nkhaus. Nws cov qauv semi-circular ua haujlwm los ntawm kev hloov qhov hnyav ntawm tus choj thiab nws cov loads mus rau ob lub abutments. Lub ntuj nkhaus ntawm lub koov thiab nws muaj peev xwm mus disperse lub zog sab nraud ho txo ​​cov teebmeem ntawm nro nyob rau hauv underside ntawm lub koov.

Cov choj no yog siv rau txhua yam los ntawm cov neeg taug kev mus rau cov tsheb ciav hlau hnyav. Qhov tsis zoo rau hom kev tsim choj no yog qhov me me thiab kev tsim kho qeeb.

 

 

Cable-Stayed Choj

Tus choj txuas txuas txuas txuas tseem yog ib qho kev tsim qauv nrov rau kev nthuav dav ntau dua li cov choj cantilever thiab luv dua li cov txuas txuas ntev tshaj plaws, nrog rau nws cov qauv tsim rov qab mus rau xyoo pua 16th.

Ib txoj hlua txuas txuas txuas txuas yog nyob ntawm cov yees / pylons, uas yog cov khoom thauj khoom ntawm cov qauv. Cables txuas los ntawm cov pylons mus rau lub lawj hauv qab no. Ob leeg ncaj qha los ntawm sab saum toj ntawm tus pej thuam los yog ntawm cov ntsiab lus sib txawv ntawm kab. Cov neeg feem coob koom nrog qhov tshwj xeeb no nrog cov txuas txuas txuas nrog. Hom kev tsim choj no yog siv rau qhov loj dua uas tsis tuaj yeem ua tiav nrog kev tsim choj cantilever tab sis tsawg dua tus choj ncua kev kawm. Ib qho ntawm cov teeb meem tseem ceeb nrog hom choj no yog qhov kev sib txuas hauv nruab nrab ntawm cov kab hluav taws xob tuaj yeem tso cov kab rov tav quab yuam ntawm lub lawj. Vim li no, lub lawj qauv yuav tsum tau ntxiv dag zog kom tiv taus cov zog tsis tu ncua.
