Mechanical dredging
Mechanical dredging yog txoj cai ntawm dredging cov ntaub ntawv los ntawm ib qho chaw extraction siv lub tshuab dredging.Feem ntau, muaj ib qho chaw ruaj khov, lub thoob-fab lub tshuab uas rub tawm cov khoom xav tau ua ntej xa mus rau qhov chaw xaiv.Mechanical dredging feem ntau yog ua nyob ze ntawm ntug dej hiav txwv thiab yog siv los tshem tawm cov av hauv av lossis ntawm ntug hiav txwv.
Hydraulic dredging
Thaum lub sij hawm hydraulic dredging, twj(feem ntau yog cov twj centrifugal)yog siv los tshem tawm cov av los ntawm qhov chaw dredged.Cov khoom yog nqus mus rau hauv cov yeeb nkab los ntawm hauv qab ntawm cov channel.Cov xuab zeb yog tov nrog dej los ua cov av sib tov kom yooj yim dua cov twj tso kua mis.Hydraulic dredging yuav tsum tsis muaj kev thauj mus los lossis khoom siv ntxiv vim tias cov av xau tuaj yeem thauj ncaj qha mus rau qhov chaw nyob sab nrauv, txuag nyiaj ntxiv thiab sijhawm.
Bio-khawb av
Bio-dredging yog siv cov kab mob tshwj xeeb (xws li qee cov kab mob, cov nroj tsuag dej) kom decompose thiab degrade cov organic thiab sediments hauv dej khib nyiab.Piv txwv li, kev siv cov av ntub dej hauv tsev tuaj yeem siv cov kev ua haujlwm ntawm cov nroj tsuag ntub dej thiab cov kab mob kom degrade organic teeb meem thiab tshem tawm cov teeb meem hauv cov dej khib nyiab.Txawm li cas los xij, nws tsis hais txog kev sib sau ntawm cov av tsis muaj kab mob, uas tej zaum yuav yog ib qho tseem ceeb ntawm cov sediment load thiab qhov tob hauv ntau lub pas dej thiab pas dej.Cov hom sediments no tsuas yog tshem tawm los ntawm kev siv cov cuab yeej siv tshuab dredging.
CDSR dredging hoses tuaj yeem siv rau cutter suction dredger thiab trailing suction hopper dredger
Cutter suction dredger
Lub cutter suction dredger (CSD) yog ib hom tshwj xeeb ntawm hydraulic dredger.Raws li ib qho chaw nres tsheb dredger, CSD tau nruab nrog lub taub hau tshwj xeeb rotary cutter, uas txiav thiab tawg cov sediments nyuaj, thiab tom qab ntawd nqus cov khoom siv dredged los ntawm qhov nqus hose ntawm ib kawg, thiab ntws ncaj qha mus rau hauv qhov chaw pov tseg los ntawm cov kav dej tawm.
CSDyogmuaj txiaj ntsig thiab raug nqi,nwstuaj yeem ua haujlwm hauv ntau qhov dej tob, thiab cov hniav ntse ntse ua rau lawv haum rau txhua hom av, txawm tias pob zeb thiab hauv av tawv.Yog li ntawd, nws yog dav siv nyob rau hauv loj-scale dredging tej yaam num xws li deepening ports.
Trailing suction hopper dredger
Lub trailing suction hopper dredger (TSHD) yog ib qho loj ntawm tus kheej-propelled loading tsis-stationary dredger nruab nrog lub taub hau trailing thiab hydraulic suction ntaus ntawv.Nws muaj kev ua haujlwm zoo navigation thiab tuaj yeem ua tus kheej, nws tus kheej thauj khoom thiab nws tus kheej unload.CovCDSR Hneev Hneev Hneev Hnyav Hose Set yog ib feem tseem ceeb ntawm hneev tshuab tshuab ntawm Trailing Suction Hopper Dredger (TSHD).Nws suav nrog cov txheej txheem ntawm cov hoses hloov tau txuas nrog lub hneev tshuab ntawm TSHD thiab cov raj xa dej.
TSHD yog maneuverable heev thiab zoo tshaj plaws rau dredging xoob cov ntaub ntawv thiab cov av mos xws li xuab zeb, gravel, sludge los yog av nplaum.Vim tias TSHD hloov tau yooj yim thiab ua haujlwm tau zoo txawm tias nyob rau hauv cov dej ntxhib thiab cov chaw muaj tsheb thauj neeg coob, nws feem ntau siv rau hauv qhov chaw dej tob thiab ntawm qhov nkag ntawm cov dej hiav txwv.
