Loj - cov chaw nres nkoj loj Hauv qhov chaw nres nkoj nthuav dav thiab cov phiaj xwm tu channel, thoob- log dredgers tau txais txiaj ntsig zoo rau lawv cov peev txheej excavation thiab kev ua haujlwm ruaj khov. Raws li cov qauv kev tiv thaiv ib puag ncig txuas ntxiv nce ntxiv, lub luag haujlwm ntawm lub thoob- lub log dredgers hauv ecological restoration tej yaam num tau dhau los ua qhov tseem ceeb, ua rau lawv yog ib qho cuab tam tseem ceeb hauv kev tsav tsheb kev tsim kho ntsuab dredging technologies.
Hull qauv: Tsawg- carbon steel lossis qis- alloy siab- lub zog steel (piv txwv li, Q345 series); nta tag nrho -welded qauv nrog transverse/longitudinal framing thiab ib qho hauv qab; qee chav nyob yog tsim los ua tsis yog - tus kheej - cov nkoj sib npaug.
Lub thoob - lub log lub cev: Siab- lub zog alloy steel lossis cam khwb cia hlau; yuav tsum muaj qhov sib npaug ntawm lub zog thiab kev cuam tshuam.
Hnav- cov khoom siv yooj yim (hli daim di ncauj, thoob cov hniav, liners): High-manganese steel (ZGMn13) lossis siab -chromium cam khwb cia hlau; Cov chaw feem ntau raug kho nrog tungsten carbide hardfacing lossis hnav -cov tshuaj tiv thaiv ceramic ua kom tiv taus yaig los ntawm cov av thiab xuab zeb.
Cov kav dej thiab cov twj tso kua mis: Cov khoom siv carbon steel; lined nrog siab -chromium cam khwb cia hlau, hnav- roj hmab tiv taus, los yog cov khoom siv ceramic.
