Mechanical dredging
Mechanical dredging chiitiko chekudhonza zvinhu kubva panzvimbo yekubvisa uchishandisa muchina wekuchera.Kazhinji, pane muchina wakamira, wakatarisana nebhaketi unoburitsa zvinhu zvaunoda usati waendesa kunzvimbo yekurongedza.Mechanical dredging inowanzoitwa padyo nemhenderekedzo yegungwa uye inoshandiswa kubvisa tsvina panyika kana pamhenderekedzo.
Hydraulic dredging
Munguva ye hydraulic dredging, pombi(kazhinji centrifugal pombi)dzinoshandiswa kubvisa sediment kubva panzvimbo yakacherwa.Nyaya yacho inosvetwa mupombi kubva pasi pegwara.Sediment inosanganiswa nemvura kuita musanganiswa wedhaka kuti pombi ienderere nyore.Hydraulic dredging haidi imwe midhiya yekufambisa kana michina sezvo sediment inogona kutakurwa yakananga kunzvimbo yepamhenderekedzo yegungwa, kuchengetedza imwe mari uye nguva.
Bio-dredging
Bio-dredging ndiko kushandiswa kwezvisikwa zvipenyu (zvakadai sezvimwe zvipembenene, zvidyarwa zvemumvura) kuora uye kushatisa organic zvinhu uye sediments mumvura ine tsvina.Semuyenzaniso, kushandiswa kweiyo yakavakirwa wetland system inogona kushandisa basa remanyoro emiti uye tupukanana kushatisa organic zvinhu uye zvakamiswa zvinhu mumvura ine tsvina.Zvisinei, haigadzirise kuunganidzwa kwezvimedu zvevhu, izvo zvinogona kunge zviri chikonzero chikuru chekuremerwa kwevhu uye kudzikiswa kwakadzika mumadziva mazhinji nemadziva.Aya marudzi ezvimedu anogona chete kubviswa nekushandisa mechini yekudhirowa michina.
CDSR dredging hoses inogona kuiswa kune cutter suction dredger uye trailing suction hopper dredger.
Ckusveta dredger
Iyo cutter suction dredger (CSD) imhando yakakosha yehydraulic dredger.Seyakamira dredger, iyo CSD inoshongedzerwa neyakasarudzika inotenderera yekucheka musoro, iyo inocheka nekupwanya yakaoma sediments, uye yobva yayamwa zvinhu zvakanyungudutswa kuburikidza nehose yekukwevera kune imwe magumo, uye nekuiputira yakananga munzvimbo yekurasa kubva paipi yekuburitsa.
CSDndizvoinoshanda uye isingadhuri,itinogona kushanda muhupamhi hwemvura yakadzika, uye mazino akapinza mazino anoita kuti ave akakodzera kune marudzi ose evhu, kunyange matombo uye pasi rakaoma.Naizvozvo, inoshandiswa zvakanyanya mumapurojekiti makuru ekuchera akadai sekudzika madoko.
Tkutuka kusveta hopper dredger
Iyo inoteedzera suction hopper dredger (TSHD) ihombe-yega inorodha isina-yakamira dredger ine musoro unoteedzera uye hydraulic suction mudziyo.Iyo ine yakanaka navigation performance uye inokwanisa kuzvifambisa, kuzvitakura uye kuzvitutunura.TheCDSR Bow Kuvhuvhuta Hose Set chikamu chakakosha chebow blowing system paTrailing Suction Hopper Dredger (TSHD).Inosanganisira seti yemapombi anochinjika akabatana nebow blowing system paTSHD uye pombi inoyangarara.
Iyo TSHD inofambiswa zvakanyanya uye inonyatsokodzera kudhonza zvinhu zvakasununguka uye ivhu rakapfava sejecha, matombo, matope kana ivhu.Nemhaka yokuti TSHD inoshanduka uye inoshanda zvakanaka kunyange mumvura ine utsinye uye nzvimbo dzegungwa dzine migwagwa yakawanda, inowanzoshandiswa munzvimbo dzakadzika dzemvura uye pamusuwo wemigwagwa yegungwa.
