Niaj hnub no, nrog kev txhim kho ntawm kev lag luam thiab tib neeg kev xav tau ntawm kev thauj mus los, Txhua lub nroog tab tom tsim lub subway ib nrab,Larsen steel ntawv pawgyuav tsum yog cov khoom siv hauv tsev tseem ceeb hauv kev tsim kho subway.
Larsen steel ntawv pawgmuaj lub zog siab, nruj kev sib txuas ntawm pawg thiab pawg, cov dej sib cais zoo, thiab tuaj yeem rov qab siv dua. Cov seem feem ntau ntawm cov nplooj ntawv steel feem ntau yog U-puab lossis Z-puab. U-shaped steel ntawv pawg yog siv nyob rau hauv underground railway tsim nyob rau hauv Tuam Tshoj. Nws txoj kev tso dej thiab tshem tawm, kev siv tshuab yog tib yam li I-steel pawg, tab sis nws txoj kev tsim kho tuaj yeem muab faib ua ib txheej steel ntawv pawg cofferdam, ob-txheej steel ntawv pawg cofferdam thiab npo. Vim yog lub hauv paus tob tob hauv kev tsim kho ntawm txoj kev tsheb ciav hlau hauv av, txhawm rau kom ntseeg tau tias nws txoj kev ntsug thiab kev tsim kho yooj yim, thiab ua kom nws tuaj yeem raug kaw thiab kaw, cov qauv siv feem ntau yog siv.
Larsen steel ntawv pawg ntev 12m, 15m, 18m, thiab lwm yam, channel steel ntawv pawg pawg ntev ntawm 6 ~ 9m, tus qauv thiab ntev yog txiav txim los ntawm kev suav. Steel phaj pawg muaj zoo durability. Tom qab kev tsim kho lub hauv paus hauv paus tiav lawm, cov ntawv hlau tuaj yeem rub tawm thiab rov ua dua tshiab. Kev tsim kho yooj yim thiab siv sijhawm luv luv; Channel steel ntawv pawg tsis tuaj yeem thaiv dej, nyob rau hauv thaj tsam ntawm cov dej hauv av siab, kev cais dej los yog kev ntsuas los nag yuav tsum tau ua. Channel steel phaj pawg muaj peev xwm khoov tsis muaj zog, uas feem ntau yog siv rau lub hauv paus pit lossis trench nrog qhov tob ≤ 4m, thiab kev txhawb nqa lossis rub lub thauj tog rau nkoj yuav tsum tau teem rau saum. Qhov kev txhawb nqa nruj me me thiab qhov deformation tom qab khawb yog loj. Vim tias nws muaj peev xwm khoov muaj zog, Larsen steel ntawv pawg feem ntau yog siv rau qhov tob 5m ~ 8m lub hauv paus nrog rau ib puag ncig qis, nyob ntawm kev txhawb nqa (rub thauj tog rau nkoj) installation.
