Taw qhia ntawm Larsen steel ntawv pawg

Dab tsi yogLarsen steel ntawv pawg?
Nyob rau hauv 1902, ib tug German engineer hu ua Larsen thawj zaug tsim ib hom steel ntawv pawg nrog U zoo li tus ntoo khaub lig-section thiab locks ntawm ob hnub, uas tau ua tiav nyob rau hauv engineering, thiab hu ua "Larsen Sheet Pile"Tom qab nws lub npe. Niaj hnub no, Larsen steel ntawv pawg tau raug lees paub thoob ntiaj teb thiab siv dav hauv kev txhawb nqa lub hauv paus, kev tsim vaj tsev cofferdams, kev tiv thaiv dej nyab thiab lwm yam haujlwm.

Larsen steel ntawv pawg yog cov txheej txheem thoob ntiaj teb, tib hom Lassen steel ntawv pawg tsim nyob rau hauv ntau lub teb chaws tuaj yeem sib xyaw rau hauv tib txoj haujlwm. Cov txheej txheem khoom ntawm Larsen steel ntawv pawg tau ua kom pom tseeb cov kev cai thiab cov kev cai ntawm qhov loj ntawm ntu ntu, xauv style, tshuaj muaj pes tsawg leeg, cov khoom siv kho tshuab thiab cov qauv tshuaj xyuas ntawm cov khoom, thiab cov khoom yuav tsum tau soj ntsuam nruj me ntsis ntawm lub Hoobkas. Yog li ntawd, Larsen steel ntawv pawg muaj kev ruaj ntseg zoo thiab cov khoom siv kho tshuab, thiab tuaj yeem siv rov ua cov khoom siv rov qab, uas muaj qhov zoo tshaj plaws hauv kev ua kom muaj kev tsim kho zoo thiab txo cov nqi tsim khoom.

 

Hom ntawm Larsen steel ntawv pawg

Raws li qhov sib txawv ntawm qhov dav, qhov siab thiab tuab, Larsen steel ntawv pawg tuaj yeem muab faib ua ntau yam qauv, thiab qhov dav dav ntawm ib pawg ntawm feem ntau siv steel ntawv pawg feem ntau muaj peb qhov tshwj xeeb, xws li 400mm, 500mm thiab 600mm.
Qhov ntev ntawm Tensile Steel Sheet Pile tuaj yeem hloov kho thiab ua raws li qhov project xav tau, lossis tuaj yeem txiav rau hauv pawg luv lossis welded rau hauv pawg ntev tom qab kev yuav khoom. Thaum nws tsis tuaj yeem thauj cov ntawv steel ntev mus rau qhov chaw tsim kho vim muaj kev txwv ntawm cov tsheb thiab txoj kev, cov pawg ntawm tib hom tuaj yeem thauj mus rau qhov chaw tsim kho thiab tom qab ntawd welded thiab lengthened.
Larsen steel ntawv pawg khoom
Raws li lub zog ntawm cov khoom siv, cov ntaub ntawv qib ntawm Larsen steel ntawv pawg ua raws li lub teb chaws tus qauv yog Q295P, Q355P, Q390P, Q420P, Q460P, thiab lwm yam, thiab cov neeg ua raws li tus qauv Japanese yogSIB 295, SIB 390, thiab lwm yam. Cov qib sib txawv ntawm cov ntaub ntawv, ntxiv rau lawv cov tshuaj muaj pes tsawg leeg, kuj tuaj yeem welded thiab lengthened. Cov qib sib txawv ntawm cov ntaub ntawv ntxiv rau cov tshuaj sib txawv, nws cov khoom siv tshuab kuj sib txawv.
