1.Lub tuam txhab muaj kev daws teeb meem ntawm cutter technology rau shield tshuab los ntawm cov pob zeb mos mus rau cov pob zeb tawv, thiab tuaj yeem tsim thiab tsim cov khoom siv cutter kom tau raws li cov kev xav tau ntawm cov neeg siv sib txawv rau txawv underground strata (kev txhim kho ntawm cov cutter nrog cov neeg siv) raws li qhov sib txawv. yuav tsum tau ntawm cov neeg siv.
2. Cov lus cog ntawm cov thev naus laus zis, peb tau txais cov khoom siv ua kom zoo thiab kev kho cua sov, yog li cov khoom lag luam muaj kev sib raug zoo dua thiab txiav kev ua kom zoo dua.
3.Thaum tib lub sijhawm, txhawm rau txhim kho cov hnav tsis kam ntawm TBM cutters, lub siab lub zog ntawm cov cuab yeej alloy thiab cov khoom uas cov cuab yeej yooj yim hnav thaum siv tau.
4.Yog ntxiv, tom qab ua tiav cov kev siv tshuab, txhua cov ntaub thaiv npog yuav raug kuaj kom ua kom muaj qhov siab tshaj plaws vuam kev ua tau zoo ntawm cov khoom lag luam tungsten carbide ntawm cov khoom.
