Kev tsim kho qhov av tuaj yeem yog cov txheej txheem nyuaj thiab nyuaj, thiab cov ntaub ntawv steel muaj ntau daim ntawv thov tseem ceeb hauv daim teb no:
Cofferdams:Cov ntawv hlau feem ntau yog siv los tsim cov cofferdams ib ntus kom cais thaj chaw tsim kho los ntawm cov dej nkag thaum lub sijhawm khawb av. Cov cofferdams khaws dej tawm, tso cai rau pab pawg tsim kho ua haujlwm hauv qhov chaw qhuav thiab ua kom muaj kev nyab xeeb tunneling.
Txiav-thiab-Cov Npog Tunnels:Hauv kev txiav-thiab- npog qhov kev tsim kho, cov ntaub ntawv steel yog siv los tsim cov phab ntsa tuav rau qhib trenches. Cov phab ntsa no txhawb nqa ob sab ntawm kev khawb, tiv thaiv cov av tawg thiab muab qhov chaw ua haujlwm ruaj khov.
Diaphragm Phab ntsa:Rau cov qhov tob tob los yog cov neeg hla dhau los ntawm cov av tsis ruaj khov, cov phab ntsa diaphragm uas ua los ntawm cov ntawv hlau yog siv los tsim ib qho chaw ruaj khov. Cov phab ntsa no ua tus qauv txhawb nqa rau lub qhov, muab lub zog thiab ruaj khov thaum khawb.
Tunnel Underpasses:Cov ntaub ntawv hlau tuaj yeem siv los tsim cov underpasses hauv qab cov qauv uas twb muaj lawm lossis txoj hauv kev thaum lub sijhawm tsim kho qhov. Cov underpasses tso cai rau lub qhov av hla kev nyab xeeb hauv qab cov txheej txheem uas twb muaj lawm.
Kev tswj dej hauv av:Cov ntaub ntawv hlau tuaj yeem ua raws li cov phab ntsa txiav los tswj cov dej hauv av thaum lub sijhawm tsim kho qhov. Los ntawm kev tiv thaiv dej ntau dhau, pab pawg tsim kho tuaj yeem tsim kom muaj chaw ua haujlwm kom qhuav thiab nyab xeeb dua.
Av Retention thiab Erosion Control:Hauv kev tsim kho qhov av ntawm toj roob hauv pes lossis nqes hav, cov nplooj ntawv steel tuaj yeem siv los ua kom ruaj khov ntawm qhov chaw siab tshaj, tiv thaiv av yaig, thiab tswj kom muaj kev ncaj ncees ntawm thaj chaw ib puag ncig.
Nws yog ib qho tseem ceeb uas yuav tsum nco ntsoov tias cov ntawv thov tshwj xeeb ntawm cov ntawv hlau hauv qhov kev tsim kho yog nyob ntawm cov xwm txheej geological, qhov yuav tsum tau ua, thiab tsim qauv engineering. Tsim kom raug thiab kev teeb tsa ntawm cov ntawv hlau pawg yog qhov tseem ceeb los ua kom muaj kev nyab xeeb thiab ua tiav ntawm kev tsim kho qhov av. Cov kws paub txog geotechnical thiab civil engineering cov kws tshaj lij sib koom tes los xaiv cov khoom tsim nyog ntawm cov ntawv hlau thiab tsim cov shoring thiab kev txhawb nqa kom haum rau cov kev sib tw tshwj xeeb ntawm txhua qhov project.
