CCS D550 Steel Phaj

 

 

 

Main Girder Structure

 

Qhov zoo ntawm Mechanical Properties: CCS D550 steel daim hlau muaj lub zog muaj zog thiab muaj peev xwm tiv taus cov kev ntxhov siab loj heev thaum siv rau hauv tus choj loj girders. Thaum cov tsheb tab tom taug kev ntawm tus choj, cov girders tseem ceeb muaj cov khoom hnyav hnyav thiab cov khoom xa tawm uas tsim los ntawm qhov hnyav ntawm lub tsheb thiab lub zog tsav tsheb. Lub zog siab ntawm CCS D550 steel daim hlau ua kom ntseeg tau tias lub ntsiab girders yuav tsis dhau deformation ntau dhau los yog tsis ua haujlwm nyob rau hauv cov kev ua haujlwm nyuaj no. Piv txwv li, nyob rau hauv kev sib txuas ntev ntev, lub ntsiab girders ua los ntawm CCS D550 steel daim hlau tuaj yeem faib cov tsheb thauj khoom, txo qhov nruab nrab ntawm qhov deflection, thiab lav qhov smoothness ntawm tus choj nto nrog rau kev tsav tsheb.

 

Reflection of Economic Benefits: Muab piv nrog cov hlau tsis muaj zog ib txwm muaj, kev siv CCS D550 steel daim hlau tuaj yeem txo qhov loj me ntawm cov girders loj. Qhov no tsis tsuas yog pab ua kom lub qhov hnyav ntawm tus choj thiab txo qis cov nqi tsim kho vaj tse, tab sis kuj txo cov nqi ntawm cov hlau siv. Piv txwv li, nyob rau hauv ib tug nruab nrab-span beam choj, siv CCS D550 steel daim hlau los fabricate lub ntsiab girders yuav txuag tau kwv yees li 15% - 20% ntawm cov steel noj piv rau siv zoo tib yam steel daim hlau. Lub caij no, vim qhov txo qis tus kheej qhov hnyav, cov kev xav tau ntawm cov txheej txheem zoo li cov piers kuj raug txo qis, ntxiv txuag cov nqi engineering.

 

Pier Tshooj

 

Txhim khu Durability: Piers yuav tsum tau nyiaj ntau yam tsis zoo thaum lub sij hawm kev pab cuam lub neej ntawm tus choj, xws li dej ntws scouring, tshuaj erosion (xws li dej hiav txwv, acid los nag, thiab lwm yam), thiab dej khov loads (nyob rau hauv lub txias cheeb tsam). Los ntawm kev kho qhov chaw tsim nyog (xws li cov txheej tiv thaiv corrosion, galvanizing, thiab lwm yam) thiab cov qauv tsim alloy, CCS D550 steel daim hlau tuaj yeem muaj qhov zoo corrosion. Hauv cov choj nyob hauv qee thaj chaw ntug dej hiav txwv lossis thaj chaw uas muaj kev ua qias tuaj loj, siv CCS D550 steel daim hlau los ua cov piers tuaj yeem tiv taus dej hiav txwv yaig thiab tshuaj lom neeg corrosion, yog li ua kom lub neej ntev ntawm cov piers. Piv txwv li, lub xyoo corrosion-resistant ntawm CCS D550 steel phaj piers nrog tshwj xeeb nto kho nyob rau hauv seawater yuav nce li ntawm 30% - 50% piv rau cov zoo tib yam steel phaj piers.

Txhim kho Bearing Capacity: Nyob rau hauv cov nqe lus ntawm kev coj tus luj ntawm lub superstructure ntawm tus choj thiab lub tsheb thauj khoom, lub siab muaj zog tus yam ntxwv ntawm CCS D550 steel daim hlau plays lub luag hauj lwm tseem ceeb. Nws tuaj yeem muab lub zog txaus compressive thiab shear lub zog los xyuas kom meej qhov ruaj khov ntawm cov piers nyob rau hauv ntau qhov sib xyaw ua ke. Rau cov piers siab lossis piers ntawm cov txuas txuas ntev, qhov zoo ntawm cov khoom siv muaj zog yog qhov tseeb dua. Piv txwv li, nyob rau hauv kev tsim kho ntawm qhov ntev-ntev ncua kev txuas txuas hniav nyob rau hauv roob roob, cov piers ua los ntawm CCS D550 steel daim hlau yuav zoo dua dais lub loj loj ntsug thiab kab rov tav rog kis los ntawm lub ntsiab cables, yog li ua kom muaj kev ruaj ntseg tag nrho ntawm tus choj qauv.

 

Daim ntawv thov ntawm Choj Deck

 

Kev kho kom haum rau ib puag ncig nyuaj: Choj decks yog ncaj qha mus rau tej yam ntuj tso ib puag ncig thiab yuav tsum tau tiv thaiv cov influences xws li kub hloov thiab dej los nag scouring. Qhov zoo thermal stability thiab anti-scouring kev ua tau zoo ntawm CCS D550 steel daim hlau pab kom lawv hloov mus rau cov complex tej yam kev mob. Hauv qee thaj chaw uas muaj qhov sib txawv ntawm lub caij ntuj sov loj, tus choj decks yuav tsis tsim kom muaj ntau deformations lossis tawg vim thermal expansion thiab contraction. Tsis tas li ntawd, nyob rau hauv cov huab cua hnyav xws li nag xob nag cua hnyav, lawv tuaj yeem tiv taus cov dej nag thiab tswj kev ncaj ncees ntawm cov qauv.
