Uhlaka lwe-Bailey luyibhuloho elisetshenziswa kabanzi emhlabeni, futhi ibhuloho lokuqala le-Bailey Army laklanywa onjiniyela baseBrithani ngo-1938. Phakathi neMpi Yezwe II, ibhuloho lensimbi lezempi lalisetshenziswa kabanzi. Ngemva kwempi, amazwe amaningi ashintsha ibhuloho lensimbi i-Bailey ngemva kokuthuthukiswa okuthile ekusetshenzisweni kwabantu. Namuhla, idlala into ebalulekile
iqhaza ekwakhiweni kwezokuthutha kanye nokulwa nezikhukhula.
I-Bailey steel bridgeyamukela isakhiwo sensimbi esicindezelekile, okuthiwa yi-Bailey steel bridge prestressed steel structure, abantu abasohlelweni lwensimbi oluthwele ngonembeza bethula ukucindezeleka komuntu ukuze baqede ukucindezeleka komthwalo, balungise amandla angaphakathi aphezulu, bathuthukise ukuqina kwesakhiwo nokuzinza kwayo, bathuthukise. ukwakheka kwezinye izakhiwo kanye nokusebenzisa ubuchwepheshe be-prestress ukwakha uhlelo olusha. Izici zayo eziyinhloko yilezi:
1. Ngokugcwele nangokuphindaphindiwe isebenzisa amplitude yamandla okunwebeka kwensimbi, ngaleyo ndlela ikhulise umthamo wokuthwala wesakhiwo sayo.
2. Ithuthukisa isimo sokucindezeleka kwesakhiwo futhi isindise insimbi. Kusukela esimweni samanje, isakhiwo esicindezelwe singaphinda sisindise i-30% yensimbi.
3. Ithuthukisa ukuqina kwesakhiwo nokuzinza, futhi ithuthukise izici ezihlukahlukene zesakhiwo.
Isakhiwo sensimbi esicindezelwe singaveza izinzuzo ezinkulu zezomnotho, singasindisa insimbi eningi, sinciphise izindleko eziphelele. Umnotho kanye nesistimu yesakhiwo sesakhiwo sensimbi esicindezelekile, uhlelo lwebhasi kanye nenqubo, imithwalo yemvelo namandla, isakhiwo sesakhiwo kanye ne-node, indlela yokufaka kanye nentengo yezinto ezibonakalayo nezinye izici eziningi zihlobene.
Ngaphansi kwezimo ezijwayelekile, isakhiwo sensimbi esicindezelekile singasindisa i-10% ~ 20% yensimbi kanye, kanye no-20% ~ 40% wensimbi izikhathi eziningi. Futhi ukwakheka kwesistimu emisha ecindezelwe ngaphambili uma kuqhathaniswa nesakhiwo sendabuko esingacindezelwe ukuze konge insimbi izikhathi eziningana kuya kweziningi. Sengiphetha, lapho amandla amakhulu ezintweni zesakhiwo, ayanda inzuzo yezomnotho yokusebenzisa i-prestress. Isibonelo, kunamandla amaningi eduze nendawo ephakathi kwe-axis yamandla adonsela phansi yesigaba sobhongo lwesisu esiqinile. Inzuzo yezomnotho yokwamukela i-prestress iphezulu kakhulu uma iqhathaniswa naleyo ye-lattice structure beam.
Ukuze sihlangabezane nokulindelwe yikhasimende, sineqembu eliqinile, lesakhiwo sensimbi sase-China esakhiwe ngaphambilini esiphuthumayo sebhuloho le-Bailey ukwakhiwa kabusha okuhlanganisa ukumaketha, ukuthengisa, ukuklama, ukukhiqiza, ukulawula ikhwalithi, ukupakisha, indawo yokugcina impahla kanye nempahla, isevisi engcono kakhulu iyonke, singakwazi. sikunikeze amanani amahle kakhulu kanye nekhwalithi engcono kakhulu, ngoba siyiqembu elivuthiwe kakhulu!
Siyakwamukela ukuthi uvakashele inkampani yethu, imboni kanye namagumbi ethu okubonisa ukuze ubonise izinhlobonhlobo zemikhiqizo ezohlangabezana nokulindela kwakho futhi, okwamanje, ngokufinyelela kalula kuwebhusayithi yethu, abantu bethu abathengisa bazokwenza konke okusemandleni abo ukukunikeza isevisi engcono kakhulu. Uma udinga ulwazi olwengeziwe, sicela ukhululeke ukusithinta nge-imeyili noma ngocingo.
