Tus nqi tseem ceeb ntawm TBM tej tshuab yog nws qhov kev ua tau zoo, muaj peev xwm nyab xeeb thiab ua kom nyab xeeb thiab ua kom nyab xeeb thiab ua kom pom tseeb thiab ua kom pom tseeb thiab ua kom pom tseeb meej. TBM (feem tho txawv tshuab) yog ib txoj kev siv tshuab tshuab uas sib xyaw ua ke, tshuab hluav taws xob, hydraulic thiab laser thev naus laus zis. Nws yog tsuas yog siv los hloov cov tunnels hauv cov kev ua pob zeb tawv
Cov yam ntxwv zoo thiab kev siv cov xwm txheej
TBM rhuav cov pob zeb los ntawm kev sib hloov catterheads thiab riam. Cov cuab yeej txiav tuaj yeem hloov kho pob zeb ntawm kev tawv tawv. Thaum lub sij hawm khawb txuas ntxiv, TBM tseem yuav siv cov khoom siv pab pawg xws li cov tshuab txhawb cov tshuab thiab kev thauj mus los kom ntseeg tau qhov chaw ruaj khov thiab kev tsim kho kev tsim kho
TBM tau siv dav hauv kev tsim kho cov teeb meem loj xws li subways, kev tsheb nqaj hlau, thiab txuag dej. Tshwj xeeb tshaj yog nyob rau hauv cov cheeb tsam uas muaj complex genology thiab High Pob Ntsig Hardness, TBM tau pom nws qhov tseem ceeb, suav nrog kev kho kom sai, qhov tseeb ntawm qhov tseeb, thiab kev nyab xeeb
TSHAJ
Tus nqi ntawm TBM feem ntau yog nruab nrab ntawm 2 lab Yuan thiab 8 lab yuan, thiab cov qauv tshwj xeeb yuav siab dua
Kev tsim kho thiab ua haujlwm
Tus qauv ntawm TBM suav nrog kev txiav thiab cov cuab yeej mus ncig ua si, kev tsav tsheb thauj khoom, siv hluav taws xob, thiab hluav taws xob, hluav taws xob, thiab lwm yam.
Cov khoom sib xyaw ua haujlwm no ua ke kom ntseeg tau tias muaj txiaj ntsig zoo thiab kev nyab xeeb ntawm TBM.
