Tsawg sediment spillage npaum li cas: Lub thoob ntim khoom- log tsim, ua ke nrog kev nqus ncaj qha ntawm siab -concentration slurry rau hauv lub twj tso kua mis dredge, minimizes sediment dispersion thiab poob thaum lub sijhawm khawb, ua rau cov khoom siv rov qab tau zoo.
Qhov zoo ntawm txoj kab nqes excavation: Cov kev teeb tsa uas muaj ob lub thoob- cov log lossis cov txheej txheem angular tshwj xeeb xa cov kev ua tau zoo tshaj plaws thaum khawb qhov nqes hav los yog cov kauj ruam hauv dej, tswj kev ua haujlwm siab yam tsis tas yuav tsum muaj kev hloov kho ntau zaus.
Strong geological adaptability: Nws qhia tau hais tias muaj peev xwm excavation zoo nyob rau hauv cov av tawv, cohesive av, tuab xuab zeb, thiab gravel - bearing strata; nws txiav quab yuam deb tshaj li ntawm tus qauv cutter suction dredgers, thiab nws yog tsis tshua muaj plam los yog cia li tee hauv efficiency.
Kev ruaj ntseg ntau lawm: Kev sib xyaw ua ke ntawm lub thoob lub log tig thiab lub nkoj lub lateral viav vias txav ua kom muaj kev sib txuas, tsis tu ncua. Kev ua haujlwm tau zoo nyob ib puag ncig ntawm ob sab laug thiab sab xis, tsis txhob cuam tshuam kev khawb thiab txo qis kev hloov pauv hauv kev tsim khoom.
High trench - hauv qab flatness: Txoj kev txiav ntawm lub thoob log cov hniav tuaj yeem tswj tau, ua rau muaj kev khawb me me thiab lub tiaj tiaj hauv qab, uas ua rau muaj kev tswj xyuas zoo rau cov channel tom ntej lossis cov av reclamation.
