Isingeniso somkhiqizo
I-longitudinal beam iyingxenye ebalulekile ye-Bailey Bridge. Ibhuloho le-Bailey, elasungulwa unjiniyela waseBrithani uDonald West Bailey ngo-1938. Lolu hlobo lwebhuloho lwenziwe ngensimbi yokuqina okuphezulu futhi lenziwe ngezingxenye zeyunithi ye-truss ejwayelekile engasindi nemishayo, imishayo yobude, amadekhi ebhuloho, izihlalo zebhuloho nezixhumi, njll. , futhi ingahlanganiswa ngokushesha esizeni ukuze ifanele izikhala ezihlukahlukene kanye nemithwalo enemishini yokufaka ekhethekile. Truss girder bridge.
Ukwahlukaniswa Komkhiqizo
Imishayo ye-longitudinal ye-Bailey Bridge ihlukaniswe yaba izinhlobo ezimbili: imishayo ye-longitudinal ene-buckle kanye nemishayo ye-longitudinal ngaphandle kwe-buckle.
(1) Izinkinobho zishiselwe emishayweni yobude bebhande, ebekwe ezinhlangothini zombili zedekhi yebhuloho. I-tenon yedekhi yebhuloho ibekwe phakathi kwezinkinobho. Izinkinobho ezine zihlinzekwa ngezimbobo zezinto ezisemaphethelweni namabhawodi ukuze kudlule izimbobo. Idekhi yebhuloho ixhunywe ne-buckle longitudinal beam.
(2) Imishayo yobude ngaphandle kwebhande ihlelwe phakathi nendawo yebhuloho kungakhathaliseki ukuthi izinhlangothi zangaphambili nangemuva. Namuhla, ngenxa yomthwalo omkhulu wethrafikhi, imishayo ye-longitudinal nezakhiwo zamapulangwe azisasetshenziswa ngokujwayelekile. Izitezi zebhuloho lensimbi ye-Orthotropic zisetshenziswa ezimweni eziningi.
Ibhuloho lensimbi le-Bailey, ibhande lebhokisi lensimbi kanye ne-plate girder ekhiqizwe i-Zhenjiang Great Wall Heavy Industry ithunyelwa emazweni amaningi futhi yamukelwa kahle abasebenzisi. Njengamanje emazweni omhlaba wesithathu, ama-stringers asadingeka kakhulu.
