Suction- hom dredgers tau dhau los ua qhov feem ntau nrhiav- tom qab hom nkoj hauv kev lag luam dredging vim lawv cov nqi ntxiv. Raws li kev tshuaj xyuas cov ntsiab lus xws li modules, modularity, thiab modular design processes-nrog rau qhov sib txawv ntawm modular thiab zone-raws li shipbuilding-ib txoj kev tshawb fawb tau ua ib qho kev ntsuam xyuas ntawm niam txiv lub nkoj. Lub nkoj tau muab faib ua ob lub hauv paus tseem ceeb: lub hull platform module thiab dredging module, nrog rau tom kawg tau mus ntxiv subdivision. Txoj kev tshawb no tau hloov pauv niam txiv cov khoom siv dredging rau hauv peb hom kev dredging modules: cutter-suction, side-drag, thiab suction-head modules. Interface thev naus laus zis kuj tseem yog lub hom phiaj tseem ceeb ntawm kev tsim qauv tsim rau cov tshuab dredging no. Modular tsim cuam tshuam rau ntau yam ntawm lub nkoj, suav nrog kev teeb tsa dav dav, qauv, kev ua haujlwm hydrodynamic, kev ua haujlwm ntawm kev lag luam, thiab tag nrho cov qauv tsim. Txoj kev tshawb no qhia txog qhov zoo ntawm modular dredgers los ntawm kev sib piv nrog cov pa niam txiv cov nkoj hla ntau qhov kev ntsuas: tsim thiab siv sijhawm sijhawm, kev saib xyuas thiab rov ua dua tshiab, kev ua haujlwm muaj, thiab lub platform thiab cov yam ntxwv.
Cutter- suction dredgers yog cov thawj lub nkoj siv hauv kev lag luam dredging; dynamic kev txiav txim ntawm lawv rotating cutter taub hau yog ib qho tseem ceeb ua rau sediment tso tawm thiab turbidity tiam. Kev ntsuas tus lej siv ib qho - tus qauv lub cev qhov ntev qhia tau hais tias txoj kab nqes tsis ua haujlwm (hauv qab dej nqes hav tawg) yog qhov tseem ceeb ntawm cov av tso tawm. Qhov sib piv txiav tau txheeb xyuas tias yog qhov kev ua haujlwm tseem ceeb tshaj plaws txog qhov tshwm sim turbidity tam sim no.
