isingeniso somkhiqizo
Insimbi yebhokisi lensimbi, ebizwa nangokuthi i-steel box girder, iyindlela yesakhiwo evame ukusetshenziswa kumabhuloho amade. Ngokuvamile lisetshenziswa emabhulohweni amakhulu, libizwa ngokuthi i-steel box girder ngoba libukeka njengebhokisi.Ingahlukaniswa ngezinhlobo ezintathu: ibhuloho elilodwa lebhokisi lebhokisi, ibhuloho le-double girder, kanye nebhuloho lamabhokisi amaningi.
Emabhulohweni asekelwe ngekhebula amakhulu, ibhande eliyinhloko lebhokisi lensimbi lidlula amakhulu ambalwa amamitha noma izinkulungwane zamamitha.
Ihlukaniswe ngezigaba eziningana zemishayo yokukhiqiza nokufakwa, futhi ingxenye yayo yesiphambano inezici zomumo obanzi nesicaba, futhi isilinganiso se-aspect ratio sifinyelela cishe ku-1:10. Ibhande lebhokisi lensimbi ngokuvamile lakhiwa ngokushisela ngokuphelele ipuleti eliphezulu, ipuleti elingaphansi, iwebhu, kanye nokuhlukanisa okuphambene, ama-partitions ama-longitudinal kanye neziqinisekiso. Ipuleti eliphezulu liyidekhi yebhuloho le-orthotropic elakhiwe ipuleti lekhava kanye nama-longitudinal stiffeners. Ubukhulu bepuleti ngalinye lebhande lensimbi elivamile kungaba: ukujiya kwekhava okungu-14mm, ukujiya kwezimbambo ezimise okwe-U ubude obungu-6mm, ububanzi bomlomo ongenhla buyi-320mm, ububanzi bomlomo ophansi bungu-170mm, ukuphakama bungu-260mm, isikhala esingu-620mm; ugqinsi lwepuleti elingaphansi 10mm, izigxivizo eziqinile ezimise okwe-U longitudinal; Ukuqina kwewebhu ethambekele kungu-14mm, ukujiya kwewebhu ephakathi kungu-9mm; ukuhlukaniswa kwama-partitions aguquguqukayo ngu-4.0m, kanti ukujiya kungu-12mm; ubude be-beam buyi-2 ~ 3.5m.
Ibhande lebhokisi lensimbi liwuhlobo lwesakhiwo oluvame ukusetshenziswa kubunjiniyela. Ukuze kufundwe umthelela wesikhala samadiaphragm avundlanayo ekuhlanekezeleni kwebhande lebhokisi lensimbi elisekelwa kalula ngaphansi komthwalo ogxilisiwe, ibhande lebhokisi lensimbi elisekelayo elinezinombolo ezihlukene zamadiaphragm aguquguqukayo lamiswa ukuze liqhathanise umphumela walo Wokuhlanekezela kanye nomphumela wokugoqa oqinile. ngaphansi komthwalo, ijika lokushintsha lomphumela omkhulu wokuhlanekezela nenani lama-diaphragms liyatholakala. Umthwalo ogxilile usetshenziswa phezulu kwewebhu yebhande lebhokisi, futhi wamukelwa ngokuvumelana nezimo ezine zokusebenza zokuhlanekezela, ukugoqa okuqinile, ukugoba okulinganayo kanye nomthwalo we-eccentric. Indlela yokubola komthwalo ibalwa.
Imboni ye-Zhenjiang Great Wall Heavy inamathani angaphezu kuka-50 okhrayini, idizayini yobungcweti, amaqembu okushisela, kanye nokufakwa enza ukukhiqizwa nokufaka imishayo yamabhokisi ensimbi ehlukahlukene.
Izinhlelo zokusebenza zomkhiqizo
Ngenxa yesakhiwo sawo, ibhande lebhokisi lensimbi livame ukusetshenziselwa ibhande lebhokisi lensimbi eliphakeme kanye ne-ramp; Inhlangano yethrafikhi yesikhathi sokwakha ibhuloho elinekhebula elihlala isikhathi eside, ibhuloho elimisiwe, ibhuloho eliyi-arch eliqinisa ibhande kanye nebhuloho labahamba ngezinyawo.
Izinzuzo zomkhiqizo
1. Amandla aqinile aphezulu kanye nomthamo omkhulu wokuthwala
2. Isakhiwo esikhanyayo, esilungele amabhuloho amade
3. Ukufakwa okulula, izindleko eziphansi, umjikelezo omfushane
4. Ikhwalithi eqinisekisiwe kanye nenani, nokuthembeka okuphezulu
5. Ukusebenza kahle kokwakhiwa okuphezulu nokuphepha okuphezulu
