Mukukhishwa kwe-echanical
I-Mechanical dredging isenzo sokudonsa izinto endaweni yokukhipha kusetshenziswa umshini wokudonsa.Ngokuvamile, kunomshini omile, obheke ebhakedeni okhipha impahla oyifunayo ngaphambi kokuyiletha endaweni yokuhlungwa.Ukumba ngemishini kuvame ukwenziwa eduze nogu futhi kusetshenziselwa ukususa inzika emhlabeni noma ogwini.
Ukukhishwa kwe-hydraulic
Ngesikhathi sokudonsa nge-hydraulic, amaphampu(ngokuvamile amaphampu e-centrifugal)zisetshenziselwa ukususa i-sediment endaweni ekhishwe.Impahla imuncwa epayipini kusukela phansi kwesiteshi.I-sediment ixutshwa namanzi ukwenza ingxube yodaka ukuze kube lula ukulethwa kwepompo.I-Hydraulic dredging ayidingi imidiya yezokuthutha eyengeziwe noma izinto zokusebenza njengoba inzika ingathuthwa iyiswe ngqo endaweni engasogwini, konga izindleko ezengeziwe nesikhathi.
I-Bio-ukudonsa
I-Bio-dredging ukusetshenziswa kwezinto ezithile eziphilayo (njengama-microorganisms athile, izitshalo zasemanzini) ukubola nokucekela phansi izinto eziphilayo kanye nenhlabathi emanzini angcolile.Isibonelo, ukusetshenziswa kohlelo lwamaxhaphozi olwakhiwe kungasebenzisa umsebenzi wezitshalo zasemanzini kanye nama-microorganisms ukonakalisa izinto eziphilayo kanye nezinto ezimisiwe emanzini angcolile.Nokho, ayikubheki ukunqwabelana kwezinhlayiya zomhlabathi ezingaphili, okungase kube imbangela enkulu yomthwalo wenhlabathi nokuncipha kokujula emachibini amaningi nasemachibini.Lezi zinhlobo zama-sediments zingasuswa kuphela kusetshenziswa imishini yokudonsa ngomshini.
I-CDSR dredging hoses ingafakwa ku-cutter suction dredger kanye ne-trailing suction hopper dredger
Ci-dredger yokumunca ngokuphelele
I-cutter suction dredger (CSD) iwuhlobo olukhethekile lwe-hydraulic dredger.Njenge-dredger emile, i-CSD ifakwe ikhanda elikhethekile lokusika elijikelezayo, elisika futhi liphule ama-sediments aqinile, bese limunca okokusebenza okudonsiwe ngepayipi elimunca ekugcineni, bese liyiphonsa ngqo endaweni yokulahla ipayipi elikhiphayo.
CSDkuyintoesebenza kahle futhi eyongayo,yonaingasebenza ekujuleni kwamanzi anhlobonhlobo, futhi izindwani ezinamazinyo abukhali ziwenza afanelekele zonke izinhlobo zenhlabathi, ngisho namadwala nomhlabathi oqinile.Ngakho-ke, isetshenziswa kabanzi kumaphrojekthi amakhulu wokudonsa njengamachweba ajulile.
Ti-reiling suction hopper dredger
I-hopper yokuncela elandelayo i-dredger (TSHD) iyidrayivu enkulu ekwazi ukuziqhubela ngaphandle kokumisa efakwe ikhanda elilandelanayo kanye nedivayisi yokumunca i-hydraulic.Inokusebenza okuhle kokuzulazula futhi iyakwazi ukuziqhubela, ukuzilayisha nokuzikhulula.ICDSR Bow Blowing Hose Isethi iyingxenye ebalulekile yohlelo lokufutha umnsalo ku-Trailing Suction Hopper Dredger (TSHD).Ihlanganisa isethi yamapayipi aguquguqukayo axhunywe nesistimu yokuvuthela ngomnsalo ku-TSHD kanye nepayipi elintantayo.
I-TSHD iyakwazi ukulawuleka kalula futhi ifaneleka kakhulu ukudonsa izinto ezixegayo kanye nenhlabathi ethambile njengesihlabathi, amatshe, udaka noma ubumba.Ngenxa yokuthi i-TSHD iguquguquka kakhulu futhi isebenza kahle ngisho nasemanzini amabi nasezindaweni zasolwandle ezinethrafikhi ephezulu, ivame ukusetshenziswa ezindaweni ezijulile kanye nasekungeneni kwemigudu yasolwandle.
