Mkuwonongeka kwa echanical
Mechanical dredging ndikuchotsa zinthu kuchokera pamalo ochotsa pogwiritsa ntchito makina obowola.Nthawi zambiri, pamakhala makina osasunthika, oyang'ana ndowa omwe amachotsa zinthu zomwe akufuna asanazipereke kumalo osankhidwa.Kubowola kwamakina nthawi zambiri kumachitika pafupi ndi gombe ndipo kumagwiritsidwa ntchito pochotsa matope pamtunda kapena m'mphepete mwa nyanja.
Kutulutsa kwa hydraulic
Pa hydraulic dredging, mapampu(kawirikawiri mapampu centrifugal)amagwiritsidwa ntchito kuchotsa matope pamalo ophwanyidwa.Zinthuzo zimayamwa mu chitoliro kuchokera pansi pa njira.Chidacho chimasakanizidwa ndi madzi kuti chisakanize matope kuti pampu ikhale yosavuta kutumiza.Hydraulic dredging sifunikira njira zowonjezera zoyendera kapena zida chifukwa matope amatha kutengedwa kupita kumalo akumtunda, kupulumutsa ndalama zowonjezera komanso nthawi.
Zamoyo-kuwononga
Bio-dredging ndi kugwiritsa ntchito zamoyo zinazake (monga tizilombo tating'onoting'ono, zomera zam'madzi) kuti ziwononge ndi kuwononga zinthu zamoyo ndi matope m'madzi oipa.Mwachitsanzo, kugwiritsa ntchito dothi lopangidwa kungathe kugwiritsa ntchito zomera za m'dambo ndi tizilombo tating'onoting'ono kuti tiwononge zinthu zamoyo ndi zinthu zomwe zayimitsidwa m'madzi oipa.Komabe, sizikhudza kusonkhanitsa tinthu tating'onoting'ono ta nthaka, zomwe zingakhale chifukwa chachikulu cha kuchulukira kwa zinyalala ndi kuchepetsa kuya m'mayiwe ndi nyanja zambiri.Mitundu iyi ya matope imatha kuchotsedwa kokha pogwiritsa ntchito zida zamakina zokopera.
CDSR dredging hoses itha kugwiritsidwa ntchito ku cutter suction dredger ndi trailing suction hopper dredger.
Ckuyamwa konse
Cutter suction dredger (CSD) ndi mtundu wapadera wa hydraulic dredger.Monga choyimitsira choyima, CSD ili ndi mutu wapadera wodula wozungulira, womwe umadula ndikuphwanya matope olimba, kenako imayamwa zinthu zopukutidwa kudzera papaipi yoyamwa kumapeto kwina, ndikuyiyika molunjika pamalo otayira kuchokera papaipi yotulutsa.
CSDndizothandiza komanso zotsika mtengo,izoimatha kugwira ntchito mozama m'madzi ambiri, ndipo masamba akuthwa okhala ndi mano amawapangitsa kukhala oyenera dothi lamitundu yonse, ngakhale miyala ndi nthaka yolimba.Chifukwa chake, imagwiritsidwa ntchito kwambiri pama projekiti akulu akulu ngati kuzama madoko.
Tdredger woyamwitsa suction hopper
Chovala choyamwa chotsatira dredger (TSHD) ndi chowotcha chachikulu chodziyendetsa chokha chomwe sichimayima chokhala ndi mutu wotsatira komanso chipangizo cha hydraulic suction.Ili ndi machitidwe abwino oyenda ndipo imatha kudziyendetsa yokha, kudzikweza yokha komanso kudzitsitsa.TheCDSR Bow Kuwomba Hose Set ndi gawo lofunikira la makina owombera uta pa Trailing Suction Hopper Dredger (TSHD).Zimaphatikizapo ma hoses osinthika olumikizidwa ndi makina owombera uta pa TSHD ndi payipi yoyandama.
TSHD ndiyotheka kusuntha komanso yoyenerera kugwetsa zinthu zotayirira ndi dothi lofewa monga mchenga, miyala, matope kapena dongo.Chifukwa TSHD imasinthasintha kwambiri ndipo imagwira ntchito bwino ngakhale m'madzi ovuta komanso madera a m'madzi othamanga kwambiri, nthawi zambiri amagwiritsidwa ntchito m'madera akuya komanso pakhomo la njira zapanyanja.
