Ndeapi maitiro eBailey Steel Bridge?

Bailey frame ibhiriji rinoshandiswa zvakanyanya munyika, uye yekutanga Bailey Army Bridge yakagadzirwa nemainjiniya eBritain muna 1938. Munguva yeHondo Yenyika II, bhiriji resimbi rehondo rakashandiswa zvakanyanya. Mushure mehondo, nyika zhinji dzakashandura bhiriji resimbi yeBailey mushure mekuvandudzwa kwekushandiswa kwevanhu. Nhasi, inotamba chinhu chakakosha

basa mukuvaka chekufambisa uye kurwisa mafashama.

Bailey simbi zambukoyakatora chimiro chesimbi chakatsikiswa, icho chinonzi Bailey simbi bhiriji prestressed simbi chimiro, vanhu vari musimbi dhizaini inotakura sisitimu nekuziva vakaunza kushushikana kwevanhu kudzikamisa kushushikana kwemutoro, gadzirisa peak simba remukati, kusimudzira kuoma kwechimiro uye kugadzikana kwayo, kuvandudza. chimiro chezvimwe zvivakwa uye kushandisa prestress tekinoroji kugadzira hurongwa hutsva. Zvinhu zvayo zvikuru ndezvi:

1. Zvizere uye zvinodzokorora kushandisa elastic simba amplitude yesimbi, nokudaro kuwedzera kutakura kukwanisa kwechimiro chayo.

2. Inovandudza mamiriro ekunetseka kwemaitiro uye inochengetedza simbi. Kubva pamamiriro ezvinhu epanguva ino, chimiro chakasimbiswa chinogonawo kuchengetedza 30% yesimbi.

3. Inovandudza kuoma kwemaitiro uye kugadzikana, uye inovandudza zvinhu zvakasiyana-siyana zvechimiro.

Prestressed simbi chimiro chinogona kuburitsa mabhenefiti makuru ehupfumi, inogona kuchengetedza yakawanda simbi, kuderedza mutengo wakazara. Iyo hupfumi uye hurongwa hwehurongwa hwe prestressed simbi dhizaini, bhazi chirongwa uye maitiro, inotakura zvisikwa uye simba, dhizaini chimiro uye node, nzira yekuisa uye mutengo wezvinhu uye zvimwe zvinhu zvakawanda zvine hukama.

Mumamiriro ezvinhu akajairika, iyo yakasimbiswa simbi chimiro inogona kuchengetedza 10% ~ 20% yesimbi kamwe chete, uye 20% ~ 40% yesimbi kakawanda. Uye prestressed innovation system chimiro kana ichienzaniswa neiyo isina-prestressed yechinyakare chimiro kuchengetedza simbi kakawanda kusvika makumi enguva. Mukupedzisa, iyo yakakura simba rinogoneka muzvigadzirwa zvezvimiro, kunowedzera hupfumi hwekushandisa prestress. Semuenzaniso, kune simba rakawanda rinogoneka padhuze nepakati pegiravhiti axis yechikamu chakasimba chebelly beam. Kubatsira kwehupfumi kwekutora prestress kwakakwira zvakanyanya kana zvichienzaniswa neiyo yelattice chimiro danda.

Kuti tisangane nezvinodiwa nevatengi, tine timu yakasimba, yeChina simbi chimiro prefabricated bhiriji emergency Bailey bhiriji regeneration dhizaini inosanganisira kushambadzira, kutengesa, dhizaini, kugadzira, kutonga kwemhando, kurongedza, kuchengetera zvinhu uye zvinhu, iyo yakanakisa yese sevhisi, tinogona kukupa iyo yakanyanya kunaka mutengo uye yakanakisa mhando, nekuti isu tiri timu yakakura kwazvo!

Tinokugamuchira iwe kuti ushanyire kambani yedu, fekitori uye makamuri edu ekuratidzira kuti uratidze zvakasiyana-siyana zvezvigadzirwa zvinosangana nezvaunotarisira uye, panguva iyo, nekuwana nyore kune webhusaiti yedu, vanhu vedu vekutengesa vachaita zvavanogona kuti vakupe iwe basa rakanakisisa. Kana iwe uchida rumwe ruzivo, ndapota inzwa wakasununguka kutibata nesu neemail kana nefoni.
