Mukuchithwa kwe-echanical
Ukutsalwa koomatshini sisenzo sokukhupha izinto kwindawo yokutsalwa kusetyenziswa umatshini wokutsala.Amaxesha amaninzi, kukho umatshini omileyo, ojonge ibhakethi okhupha imathiriyeli oyifunayo phambi kokuba uyizise kwindawo yokuhlela.Ukuchithwa koomatshini kudla ngokuqhutywa kufutshane nonxweme kwaye kusetyenziselwa ukususa intlenga emhlabeni okanye kunxweme.
Ukuchithwa kwe-hydraulic
Ngexesha le-hydraulic dredging, iimpompo(ngokuqhelekileyo iimpompo ze-centrifugal)zisetyenziselwa ukususa intlenga kwindawo eyotyiweyo.Izinto eziphathekayo zifakwe kumbhobho ukusuka ngaphantsi komjelo.Intlenga ixutywa namanzi ukwenza umxube wodaka ukuze kube lula ukuhanjiswa kwempompo.I-Hydraulic dredging ayifuni imidiya yezothutho eyongezelelweyo okanye izixhobo njengoko intlenga inokuthuthwa ngokuthe ngqo kwindawo eselunxwemeni, konga inkcitho kunye nexesha elongezelelweyo.
Ubomi-ukukrazula
I-Bio-dredging kukusetyenziswa kwezinto eziphilayo ezithile (ezifana ne-microorganisms ezithile, izityalo zasemanzini) ukubola kunye nokunciphisa izinto eziphilayo kunye nentlenga kumanzi amdaka.Umzekelo, ukusetyenziswa kwenkqubo ye-wetland eyakhiweyo kunokusebenzisa umsebenzi wezityalo ze-wetland kunye ne-microorganisms ukuthobisa i-organic matter kunye ne-suspended matter kumanzi amdaka.Nangona kunjalo, ayijongani nokuqokelelwa kwamasuntswana omhlaba, nto leyo enokuba ngunobangela omkhulu womthwalo wentlenga kunye nokunciphisa ubunzulu kumachibi amaninzi namachibi.Olu didi lwentlenga lunokususwa kuphela ngokusebenzisa izixhobo zokucoca ngoomatshini.
I-CDSR dredging hoses inokufakwa kwi-cutter suction dredger kunye ne-trailing suction hopper dredger.
Cidredger yokufunxa
I-cutter suction dredger (CSD) luhlobo olukhethekileyo lwe-hydraulic dredger.Njengomatshini wokumisa omileyo, i-CSD ixhotyiswe ngentloko ekhethekileyo yokusika ejikelezayo, esika kwaye yophule intlenga eqinileyo, emva koko ifunxe izinto ezotyiweyo ngombhobho wokufunxa kwelinye icala, kwaye iyigungxule ngqo kwindawo yokulahla kumbhobho wokukhupha.
CSDyiesebenzayo kwaye eyongayo,yonainokusebenza kuluhlu olubanzi lobunzulu bamanzi, kwaye amazinyo abukhali awenza afaneleke kuzo zonke iintlobo zomhlaba, nkqu namatye nomhlaba oqinileyo.Ke ngoko, isetyenziswa ngokubanzi kwiiprojekthi ezinkulu zokutsala ezinje ngezibuko ezinzulu.
Tukufunxa ihopper dredger
Ihopha yokufunxa elandelayo i-dredger (TSHD) yidrayivu enkulu ekwaziyo ukuziqhubela ukulayisha engasebenziyo exhotyiswe ngentloko elandelanayo kunye nesixhobo sokufunxa i-hydraulic.Inokusebenza kakuhle kokukhangela kwaye iyakwazi ukuziqhubela, ukuzilayisha ngokwakho kunye nokuzikhulula.IIseti ye-CDSR yokuvuthela iHose yinxalenye ebalulekileyo yenkqubo yokuvuthela isaphetha kwi-Trailing Suction Hopper Dredger (TSHD).Ibandakanya isethi yee-hoses eziguquguqukayo ezidityaniswe nenkqubo yokuvuthela isaphetha kwi-TSHD kunye nombhobho odadayo.
I-TSHD iyakwazi ukulawuleka kakhulu kwaye ifaneleke kakhulu ukukhupha izinto ezixeliweyo kunye nomhlaba othambileyo onjengesanti, igrabile, i-sludge okanye udongwe.Ngenxa yokuba i-TSHD iguquguqukayo kwaye isebenza ngokufanelekileyo nakumanzi anqabileyo kunye neendawo eziphakamileyo zaselwandle, zihlala zisetyenziselwa kwiindawo ezinzulu kunye nokungena kwiindlela zolwandle.
