Nrog rau txoj kev loj hlob ntawm nroog loj, muaj ntau thiab ntau lub tsev siab siab, thiab qhov sib sib zog nqus hauv paus qhov kev txhawb nqa cov txheej txheem kev suav thiab cov ntaub ntawv xeem yog qhov tseem ceeb dua. Daim ntawv thov ntawm axial force support system yog ib qho tseem ceeb ntawm kev ceeb toom ntxov nyob rau hauv cov txheej txheem ntawm lub hauv paus tob excavation. nplhaib.
Lub zog axial txhawb kev txawj ntse tswj hydraulic system saib xyuas cov axial quab yuam txav ntawm lub sijhawm, lub zog axial tau txais nyiaj them rov qab, thiab kev ua haujlwm ntawm tus kheej ntawm lub zog axial txhawb nqa hydraulic jack zoo heev nce kev ruaj ntseg thiab kev nyab xeeb ntawm qhov project.
