Vim li cas LSAW Steel Yeeb Nkab Yog Qhov Zoo Tshaj Plaws Rau Choj Piling Thiab Superstructures?

Cov choj yog qhov tseem ceeb ntawm kev tsim vaj tsev, txuas cov zej zog, txhawb kev lag luam, thiab kov yeej thaj chaw teeb meem. Kev ncaj ncees thiab kev ua neej ntev ntawm cov qauv tseem ceeb no yog nyob ntawm lub hauv paus ntawm lub zog thiab kev ntseeg siab ntawm lawv cov hauv paus ntsiab lus thiab cov qauv tsim. Hauv kev tsim cov choj niaj hnub no, Longitudinally Submerged Arc Welded (LSAW) steel kav tau tshwm sim los ua qhov kev xaiv zoo tshaj plaws rau ob qho tib si piling thiab ntau yam kev siv superstructure. Tab sis yog vim li cas LSAW steel yeeb nkab yog qhov kev xaiv zoo tshaj plaws rau kev sib txuas ntawm cov kav dej thiab cov txheej txheem loj, thiab lawv qhov zoo li cas rau lwm cov ntaub ntawv? Hebei Huayang Steel Pipe Co., Ltd., yog ib lub tuam txhab ua lag luam ntawm siab - zoo LSAW steel kav, tshawb txog cov laj thawj tseem ceeb tom qab lawv qhov kev siv dav hauv kev tsim choj.

Qhov Kev Xav Tau Ib puag ncig ntawm Kev Tsim Kho Choj

Cov qauv choj ntsib ntau yam teeb meem thoob plaws hauv lawv lub neej:

•Imense Static thiab Dynamic Loads: Cov choj yuav tsum txhawb nqa lawv tus kheej qhov hnyav, tsheb thauj khoom (nrog rau cov tsheb hnyav), thiab ib puag ncig lub zog xws li cua, seismic kev ua si, thiab dej ntws.

•Harsh Environmental Exposure: Cov pawg feem ntau tau tsav mus rau hauv cov av hnyav, nrog rau cov chaw nyob hauv hiav txwv, thaum lub tsev loj loj raug rau huab cua, qhov kub thiab txias, thiab cov huab cua corrosive.

•Long Tsim Lub Neej: Cov choj yog tsim los rau ntau xyoo, feem ntau ib puas xyoo lossis ntau dua, xav tau cov ntaub ntawv tshwj xeeb nrog kev ua haujlwm ntev thiab kev saib xyuas tsawg.

• Kev Tsim Kho Kev Ua Haujlwm: Loj- cov phiaj xwm choj loj xav tau cov ntaub ntawv uas yooj yim thiab raug nqi- siv tau zoo.

Superiority ntawmLSAW Steel Pipeshauv Bridge Applications

LSAW steel kav muaj ib qho kev sib xyaw ua ke ntawm cov khoom uas ua rau lawv zoo tshaj plaws - haum rau ob qho tib si substructure (piling) thiab superstructure ntawm choj:

1. Siab zog-rau-Qhov hnyav piv thiab Load-Bearing Capacity

•Efficient Load Transfer: LSAW kav yog tsim los ntawm qib siab - lub zog steel qib (xws li API 5L X52, X60, X70), muab kev thauj khoom zoo heev - nqa lub peev xwm rau ob qho tib si axial ( ntsug) thiab sab nraud. Qhov no tso cai rau kev tsim cov khoom sib dua tsis tau muaj zog txuas ntxiv.

•Optimized Piling: Rau choj piling, loj - txoj kab uas hla LSAW kav yuav hloov tau cov loads tseem ceeb rau tob, ruaj khov av strata, txo cov pawg uas yuav tsum tau thiab simplifying lub hauv paus tsim.

•Structural Efficiency: Nyob rau hauv superstructures, lawv lub zog siab tso cai rau ntev spans thiab ntau slender designs, pab txhawb rau aesthetic thov thiab cov khoom efficiency.

2. Txoj kab uas hla loj thiab hnyav phab ntsa Thickness muaj peev xwm

LSAW thev naus laus zis ua tau zoo ntawm kev tsim cov kav dej nrog cov kab uas loj heev (txog 1422mm lossis ntau dua) thiab cov phab ntsa hnyav (txog 80mm lossis ntau dua). Qhov no yog tshwj xeeb tshaj yog zoo rau cov choj vim:

•Deep Foundations: Loj- txoj kab uas hla, tuab- cov kav LSAW phab ntsa tuaj yeem raug tsav los yog drilled mus rau qhov tob tob, muab cov hauv paus ruaj khov rau cov qauv choj loj.

•Caissons thiab Cofferdams: Lawv tuaj yeem siv ua caissons mus tas li lossis cov cofferdams ib ntus, muab qhov chaw ua haujlwm qhuav rau kev tsim kho hauv cov dej.

•Main Girders thiab Arches: Nyob rau hauv superstructures, loj LSAW kav yuav ua tau lub ntsiab girders, arch ribs, los yog chords ntawm truss choj, muab siab dabtsi yog khoov nruj thiab torsional tsis kam.

3. Zoo heev Ductility thiab Seismic Resistance

Hlau, thiab tshwj xeeb tshaj yog cov kav dej LSAW tsim los rau cov qauv nruj, ua pov thawj zoo ductility. Cov cuab yeej no tseem ceeb heev rau cov txuas hniav hauv thaj tsam seismic, vim nws tso cai rau cov qauv kom deform plastically thiab nqus seismic zog yam tsis muaj kev puas tsuaj, tiv thaiv kev puas tsuaj loj thaum muaj av qeeg. Cov txheej txheem welding tswj thiab xaiv cov khoom kom ntseeg tau tias LSAW weld seam tswj kev sib piv ductility rau cov khoom niam txiv.

4. Robust Weld Seam Kev ntseeg siab thiab kev ruaj ntseg zoo

Txoj kev tsim khoom ntawm LSAW, suav nrog ob -sided submerged arc vuam, ua kom muaj - zoo, puv - nkag mus rau weld seam. Cov txheej txheem no yog raug rau ntau yam tsis yog-Kev Ntsuas Kev Puas Tsuaj (NDT), suav nrog kev kuaj xyuas ultrasonic thiab radiographic, kom ntseeg tau tias cov vuam tsis muaj qhov tsis xws luag thiab muaj cov khoom siv kho tshuab sib npaug rau cov hlau puag. Qhov kev tswj xyuas kom zoo no yog qhov tseem ceeb rau lub sijhawm ntev - kev ntseeg siab ntawm cov khoom siv choj.

5. Versatility hauv Fabrication thiab Installation

•Customizable Lengths: LSAW kav yuav ua tau nyob rau hauv ib tug ntev ib seem, txo qhov chaw vuam. Lawv kuj tuaj yeem txiav tau yooj yim, welded, thiab fabricated rau hauv cov duab nyuaj los yog kev koom ua ke nrog lwm yam khoom siv.

•Concrete-Filled Steel Tubes (CFST): LSAW cov kav dej tuaj yeem ua tiav nrog cov pob zeb los tsim cov tswv cuab sib xyaw (CFST kab lossis pawg), ua kom lawv lub zog compressive, nruj, thiab hluav taws kub, thaum khaws cov ductility ntawm cov hlau.

• Yooj yim ntawm kev sib txuas: Qhov tseeb qhov ntev ntawm LSAW kav dej yooj yim thiab muaj zog sib txuas rau lwm yam khoom siv, txawm tias los ntawm vuam lossis bolting.

6. Durability thiab corrosion tiv thaiv

Nrog rau cov txheej txheem tiv thaiv corrosion tsim nyog (xws li, txheej txheej sab nraud xws li 3LPE lossis FBE, cov kab hauv ob sab hauv, kev tiv thaiv cathodic), LSAW steel kav muaj qhov tshwj xeeb ua haujlwm ntev thiab lub neej ua haujlwm ntev, txawm tias nyob rau hauv kev ua phem marine lossis kev lag luam ib puag ncig. Qhov no txo ​​qis cov kev xav tau ntawm kev saib xyuas thiab ua kom tus choj tseem nyob ruaj khov rau nws lub neej tsim.
