CDSR dredging hoses feem ntau yog siv los thauj cov xuab zeb, av nkos thiab lwm yam khoom siv hauv cov dej hiav txwv dredging, txuas nrog lub nkoj dredging lossis cov cuab yeej siv los hloov cov av nkos mus rau qhov chaw xaiv los ntawm kev nqus lossis tawm.Dredging hoses ua lub luag haujlwm tseem ceeb hauv kev saib xyuas chaw nres nkoj, kev tsim kho marine engineering, dej dredging thiab lwm yam kev lag luam, muab kev txhawb nqa zoo rau kev tswj xyuas cov dej ntws zoo thiab kev tiv thaiv ib puag ncig ntawm dej.
Kev suav zaus
Dredging voj voog: Dredging voj voog yog hais txog lub sij hawm ncua sij hawm yuav tsum tau ua ib tug dredging hauj lwm.Raws li cov yam ntxwv ntawm qhov chaw nres nkoj lossis txoj kev hauv dej thiab cov kev hloov hauv dej tob, ib qho kev sib raug zoo dredging voj voog feem ntau yuav raug tsim.
Kev txheeb xyuas cov ntaub ntawv: Txheeb xyuas qhov sib txawv thiab tus nqi ntawm sedimentation nyob rau hauv cov chaw nres nkoj los yog dej raws li cov ntaub ntawv keeb kwm dredging, cov ntaub ntawv hydrological, sediment txav thiab lwm yam ntaub ntawv.
Dredging txoj kev: Raws li cov khoom yam ntxwv thiab lub peev xwm ntawm cov cuab yeej dredging, xaiv txoj kev tsim dredging thiab txheej txheem los txiav txim qhov project ntim thiab kev ua haujlwm zoo.
Cov txiaj ntsig kev suav ntawm dredging zaus yog kwv yees tus nqi, thiab tus nqi tshwj xeeb yuav tsum tau hloov kho raws li cov xwm txheej tiag tiag thiab cov kev xav tau ntawm engineering.Nyob rau tib lub sijhawm, kev suav ntawm dredging zaus kuj yuav tsum tau saib xyuas tas li thiab hloov kho kom ntseeg tau tias cov kev taw qhia ntawm qhov chaw nres nkoj lossis txoj kev dej ua tau raws li qhov yuav tsum tau ua.
Pom zoo dredging zaus
Cov kab nrib pleb (tsawg dua 20 ko taw) yuav raug kho kom zoo dua txhua ob mus rau peb xyoos
Cov kab sib sib zog nqus (tsis pub tsawg dua 20 ko taw) yuav raug kho kom zoo dua txhua tsib mus rau xya xyoo
Cov yam tseem ceeb cuam tshuam rau dredging zaus
Geographical ib puag ncig:Cov undulations ntawm cov seafloor topography thiab cov kev hloov nyob rau hauv dej tob yuav ua rau tsub zuj zuj ntawm sediments, tsim silt, sandbars, thiab lwm yam. Piv txwv li, hiav txwv cheeb tsam nyob ze ntawm lub qhov ncauj dej yog nquag mus rau cov av av vim muaj ntau cov sediment thauj los ntawm cov dej ntws..Thaum sandbars tau yooj yim tsim nyob rau hauv hiav txwv ze ntawm ntug dej hiav txwv Islands tuaj.Cov xwm txheej ntawm thaj chaw no yuav ua rau siltation ntawm txoj kev dej, yuav tsum tau ua kom cov dej ntws tsis tu ncua.
Yam tsawg kawg nkaus qhov tob:Qhov tsawg kawg nkaus qhov tob yog hais txog qhov tsawg kawg nkaus dej qhov tob uas yuav tsum tau khaws cia hauv ib lub channel lossis chaw nres nkoj, uas feem ntau yog txiav txim siab los ntawm cov qauv ntawm lub nkoj thiab kev nyab xeeb ntawm kev taug kev.Yog hais tias seabed sedimentation ua rau cov dej qhov tob poob qis dua qhov tsawg kawg nkaus qhov tob, nws yuav ua rau muaj kev pheej hmoo thiab teeb meem rau nkoj hla.Txhawm rau kom ntseeg tau tias kev taug kev thiab kev nyab xeeb ntawm cov channel, qhov zaus ntawm dredging yuav tsum tau nquag txaus los tswj cov dej hauv qhov tob tshaj qhov tsawg kawg nkaus qhov tob.
Qhov tob uas tuaj yeem dredged:Qhov tob uas tuaj yeem dredged yog qhov siab tshaj plaws ntawm cov av xuab zeb uas tuaj yeem tshem tawm tau zoo los ntawm cov khoom siv dredging.Qhov no nyob ntawm lub peev xwm ntawm cov cuab yeej siv dredging, xws li khawb qhov tob txwv ntawm lub dredge.Yog hais tias cov sediment thickness yog nyob rau hauv lub dredable qhov tob, dredging kev khiav hauj lwm yuav ua tau kom rov qab tau cov dej qhov tob uas tsim nyog.
Yuav ua li cas sai sai sediment puv cheeb tsam:Tus nqi ntawm cov sediment nyob rau hauv cheeb tsam yog tus nqi uas sediment accumulates nyob rau hauv ib cheeb tsam.Qhov no nyob ntawm cov qauv ntawm cov dej ntws thiab cov sediment thauj ceev.Yog tias cov av ntim tau sai, nws yuav ua rau cov channel lossis chaw nres nkoj ua tsis tau rau lub sijhawm luv dua.Yog li ntawd, qhov tsim nyog dredging zaus yuav tsum tau txiav txim siab raws li cov sediment filling tus nqi kom tswj tau qhov dej tob.
