Cov kav hlau steel, vim muaj ntau txoj kev tsim khoom, ntau yam duab, hom thiab cov khoom siv, yog ib qho ntawm cov khoom siv hauv tsev nrov tshaj plaws. Txawm li cas los xij, nws yuav tsum tau muab sau tseg tias kev siv cov ntsiab lus ntawm tus kheej yog txhais los ntawm hom steel kav. Txhua hom, sib nrug los ntawm universal zoo, kuj muaj cov khoom ntiag tug.
Hom ntawm cov yeeb nkab steel thiab nws qhov tsim nyog rau ib txoj haujlwm tshwj xeeb thiab qhov project yog li ntawd tseem ceeb heev los ntawm qhov pom ntawm tus neeg ua lag luam lossis tus neeg saib xyuas kev tsim kho. Cov khoom siv thiab cov cuab yeej tsim khoom muaj kev cuam tshuam rau lawv cov neeg kho tshuab lub zog, lawv tsis kam mus rau qhov kub thiab txias, thiab lawv tsis kam mus rau cov tshuaj.
Hom steel kav siv nyob rau hauv kev tsim kho kev lag luam
Cov khoom tuaj yeem muab faib ua peb hom:
● welded steel kav;
● seamless steel kav; thiab
● insulated kav.
Qhov kev xaiv yooj yim hauv feem ntau cov haujlwm yog steel welded kav, uas yog tsim los ntawm kev txiav thiab ua cov ntawv hlau. Thaum lub sijhawm kawg, lawv tau welded, uas ua rau nws muaj peev xwm hloov cov yeeb nkab rau cov kev xav tau tshwj xeeb ntawm cov neeg siv khoom. Txoj kab uas hla ntawm cov khoom tuaj yeem ua tau raws li tus qauv thiab kho raws li qhov feem ntau lees txais, nrog rau tsim los rau kev siv tshwj xeeb, kuj yog rau cov kev xav tau txawv txawv, piv txwv li hauv feem pua ntawm cov pa roj carbon.
Raws li kev tsim cov kav dej welded yog raws li kev dov ntawm ib daim ntawv lossis steel sawb rau hauv lub tog raj kheej hom, nws yog qhov tsim nyog los txuas cov npoo tom qab. Qhov no yog ua tiav siv qhov kub thiab txias. Plaub txoj kev siv rau qhov no: vuam (kev sib txuas, sib tshooj, ntawm lub tshuab dov) thiab hluav taws xob vuam.
Txawm hais tias cov yeeb nkab steel twg raug xaiv los ntawm cov tub ua lag luam, qhov tseem ceeb ntawm cov khoom lag luam yog cov kav ntev ntawm kev sib koom ua ke. Qhov no kuj tseem siv tau rau qhov ua tau categorization ntawm welded steel hlab nyob ntawm seb lawv puas yog longitudinal lossis kauv.
Seamless kav tsis muaj kev sib txuas tsim los ntawm vuam qhov kawg. Qhov tsis muaj seam ua rau cov kav dej pom zoo rau cov haujlwm uas qhov kev pheej hmoo ntawm cov dej xau yog qhov tseem ceeb. Qhov no siv, piv txwv li, rau cov kab uas muaj tshuaj. Qhov kev txwv ntawm seamless kav yog lawv txoj kab uas hla; rau cov laj thawj thev naus laus zis, qhov txwv yog 508 millimeters.
Kev siv cov kav dej hauv kev tsim kho kev lag luam
Cov kav dej yog siv nyob rau hauv tag nrho cov sectors ntawm kev tsim ua haujlwm. Muaj ntau hom kev siv: los ntawm ntug kev tiv thaiv mus rau kev tiv thaiv kev khawb. Cov kav hlau steel hauv kev tsim kho kev lag luam kuj tseem siv rau:
• drillings;
• airtight tubular phab ntsa;
• jacking;
• dhuav pawg;
• culverts;
• choj tsis kam; thiab
• cov khoom siv.
Vim lub durability thiab lub zog ntawm cov ntaub ntawv, steel kav kuj siv los ntxiv dag zog rau hauv av.
Txheeb xyuas cov kav hlau steel ntawm FERGES
Raws li tus neeg muag khoom ntawm cov kav dej steel, peb muag txhua yam khoom siv. Cov kav dej muab los ntawm FERGES yog ua los ntawm cov ntaub ntawv zoo, zoo tagnrho rau ntau yam kev tsim kho.
Tshawb xyuas cov npe ntawm cov khoom lossis hu rau lub chaw muag khoom kom paub meej ntxiv.
