Niaj hnub no, nrog rau kev txhim kho ntawm kev lag luam thiab tib neeg qhov kev xav tau kev thauj mus los, Txhua lub nroog tab tom tsim lub tsheb ciav hlau hauv av ib qho tom qab ib qho,Larsen steel sheet pileyuav tsum yog cov khoom siv tseem ceeb hauv kev tsim kho av hauv av.
Larsen steel sheet pilemuaj lub zog siab, kev sib txuas nruj ntawm cov pawg thiab cov pawg, cov dej sib cais zoo, thiab tuaj yeem rov siv dua. Cov hom seem ntawm cov hlau pawg feem ntau yog U-puab lossis Z-puab. Cov hlau pawg U-puab siv rau hauv kev tsim kho tsheb ciav hlau hauv av hauv Suav teb. Nws cov txheej txheem nqes thiab tshem tawm, kev siv tshuab zoo ib yam li I-steel pawg, tab sis nws txoj kev tsim kho tuaj yeem faib ua ib txheej hlau pawg cofferdam, ob txheej hlau pawg cofferdam thiab screen. Vim yog lub hauv paus tob thaum lub sijhawm tsim kho tsheb ciav hlau hauv av, txhawm rau kom ntseeg tau tias nws ntsug thiab yooj yim tsim kho, thiab ua rau nws tuaj yeem kaw thiab kaw, cov qauv screen feem ntau siv.
Larsen steel sheet pile ntev 12m, 15m, 18m, thiab lwm yam, channel steel sheet pile ntev ntawm 6 ~ 9m, tus qauv thiab ntev yog txiav txim siab los ntawm kev xam. Steel sheet pile muaj lub zog zoo. Tom qab kev tsim kho lub hauv paus tiav lawm, lub steel sheet pile tuaj yeem rub tawm thiab rov ua dua. Kev tsim kho yooj yim thiab lub sijhawm tsim kho luv luv; Channel steel sheet pile tsis tuaj yeem thaiv dej, nyob rau thaj chaw ntawm cov dej hauv av siab, kev cais dej lossis kev ntsuas nag. Channel steel sheet pile muaj peev xwm khoov tsis zoo, uas feem ntau yog siv rau lub hauv paus lossis qhov av nrog qhov tob ≤4m, thiab yuav tsum teeb tsa lub thauj tog rau nkoj txhawb nqa lossis rub rau saum toj. Qhov kev txhawb nqa yog me me thiab qhov deformation tom qab khawb yog loj. Vim nws muaj peev xwm khoov tau zoo, Larsen steel sheet pile feem ntau yog siv rau qhov tob 5m ~ 8m nrog cov kev xav tau ib puag ncig qis, nyob ntawm qhov kev txhawb nqa (rub anchor) kev teeb tsa.
