Ziziphi iimpawu zeBailey Steel Bridge?

I-Bailey frame yibhulorho esetyenziswa ngokubanzi ehlabathini, kwaye iBhulorho yoMkhosi yaseBailey yokuqala yayilwa ngoononjineli baseBritani ngowe-1938. Ebudeni beMfazwe Yehlabathi II, ibhulorho yentsimbi yasemkhosini yayisetyenziswa ngokubanzi. Emva kwemfazwe, amazwe amaninzi atshintsha ibhulorho yensimbi yaseBailey emva kokuphuculwa kokusetyenziswa kwabantu. Namhlanje, idlala into eyimfuneko

indima kulwakhiwo lwezothutho kunye nokulwa nezikhukhula.

Ibhulorho yentsimbi yeBaileyYamkela isakhiwo sentsimbi esicinezelekileyo, ebizwa ngokuba yiBailey steel bridge prestressed steel structure, ngabantu abakwisakhiwo sentsimbi ephethe inkqubo ngokuqonda bazisa uxinzelelo lomntu ukuphelisa uxinzelelo lomthwalo, ukulungelelanisa incopho yamandla angaphakathi, ukomeleza ukuqina kwesakhiwo kunye nokuzinza kwayo ubume bezinye iipropati kunye nokusebenzisa iteknoloji ye-prestress ukudala inkqubo entsha. Iimpawu zayo eziphambili zezi:

1. Ngokupheleleyo kwaye ngokuphindaphindiweyo isebenzisa i-amplitude yamandla e-elastic yensimbi, ngaloo ndlela ikhulisa amandla okuthwala isakhiwo sayo.

2. Ukuphucula imeko yoxinzelelo lwesakhiwo kunye nokugcina intsimbi. Ukususela kwimeko yangoku, isakhiwo esigxininisiweyo sinokugcina i-30% yentsimbi.

3. Ukuphucula ukuqina kwesakhiwo kunye nokuzinza, kunye nokuphucula iimpawu ezahlukeneyo zesakhiwo.

Isakhiwo sentsimbi egxininisiweyo sinokuvelisa inzuzo enkulu yezoqoqosho, inokugcina intsimbi eninzi, ukunciphisa iindleko ezibanzi. Uqoqosho kunye nenkqubo yesakhiwo se-prestressed steel structure, i-scheme yebhasi kunye nenkqubo, imithwalo yendalo kunye namandla, isakhiwo sesakhiwo kunye ne-node, indlela yokufakela kunye nexabiso lezinto eziphathekayo kunye nezinye izinto ezininzi ezihambelanayo.

Kwiimeko eziqhelekileyo, i-prestressed steel structure ingagcina i-10% ~ 20% yentsimbi kanye, kunye ne-20% ~ 40% yentsimbi ngamaxesha amaninzi. Kwaye i-prestressed innovation system structure xa kuthelekiswa ne-non-prestressed yendabuko isakhiwo sokugcina intsimbi amaxesha amaninzi ukuya kumaxesha amaninzi. Ukuqukumbela, amandla amakhulu anokubakho kwimathiriyeli yesakhiwo, iphezulu inzuzo yezoqoqosho yokusebenzisa i-prestress. Umzekelo, kukho amandla amaninzi kufutshane nombindi we-axis yomxhuzulane wecandelo lomqadi wesisu esiqinileyo. Inzuzo yezoqoqosho yokwamkela i-prestress iphezulu kakhulu xa ithelekiswa ne-lattice structure beam.

Ukuze sihlangabezane nokulindelwe ngabathengi, sineqela elomeleleyo, ngenxa yesakhiwo sentsimbi yaseChina esenziwe ngaphambili kwibhulorho engxamisekileyo yeBailey ibhulorho yokuvuselela uyilo olubandakanya ukuthengisa, ukuthengisa, ukuyila, imveliso, ulawulo lomgangatho, ukupakishwa, indawo yokugcina impahla kunye nokuhanjiswa, eyona nkonzo igqwesileyo iyonke, singakwazi. sikubonelele ngelona xabiso lincomekayo kunye nowona mgangatho ubalaseleyo, kuba siliqela eliqolileyo kakhulu!

Siyakwamkela ukuba undwendwele inkampani yethu, umzi-mveliso kunye namagumbi ethu okubonisa ukubonisa iintlobo ngeentlobo zeemveliso eziza kuhlangabezana nolindelo lwakho kwaye, okwangoku, ngokufikelela ngokulula kwiwebhusayithi yethu, abantu bethu abathengisayo baya kwenza konke okusemandleni abo ukukubonelela ngeyona nkonzo ilungileyo. Ukuba ufuna ulwazi oluthe kratya, nceda uzive ukhululekile ukuqhagamshelana nathi nge-imeyile okanye ngefowuni.
