Suction dredgers-xws li cutter suction dredgers, suction- taub hau dredgers, thiab trailing suction hopper dredgers- yog tam sim no feem ntau nyob rau hauv - xav tau hom nkoj hauv kev lag luam dredging vim lawv cov nqi ntxiv. Hauv kev tsim lub nkoj, kev tsim qauv tsim qauv (xws li kev teeb tsa cov khoom siv dredging rau hauv cov qauv ywj pheej rau kev txiav txiav, sab -trailing, lossis suction- lub taub hau ua haujlwm) tau txais; Qhov no ua kom yooj yim rau kev tsim qauv luv luv thiab txuag nqi thaum muaj feem cuam tshuam xws li kev teeb tsa dav dav, kev tsim qauv, thiab kev lag luam zoo. Interface technology yog tus yuam sij rau kev siv qhov modularity.
Tam sim no, kev lag luam dredging hauv tsev ntsib cov khoom siv -xav tau qhov sib txawv, thiab qhov kev thov loj heev rau dredgers nthuav tawm lub sijhawm tshiab rau Tuam Tshoj txoj kev lag luam shipbuilding.
Lub cutter suction dredger (CSD) yog thawj hom nkoj hauv kev lag luam dredging; qhov kev txiav txim ntawm nws rotating cutter taub hau yog ib qho tseem ceeb ua rau sediment tso tawm thiab turbidity tiam. Kev ua haujlwm tsis zoo (xws li qhov sib piv txiav) cuam tshuam rau qib turbidity thiab tseem ceeb heev rau kev tswj hwm ib puag ncig.
Nyob rau hauv cov dej dredging ua nyob rau hauv cov dej xws li tus dej Yangtze, kev xaiv ntawm spoil pov tseg thaj chaw yog txwv los ntawm cov khoom siv nkoj (xws li, qhov ntev ntawm cov kav dej tso tawm ntawm qhov nqus dredgers) thiab yuav tsum tau suav rau qhov tseeb evolution ntawm shoals, ua rau nws tsis tsim nyog rau deposit dredged khoom mus rau sab sauv -section hoals.
