MUkukhishwa kwe-eChanical
I-Mechan Dreadging yisenzo sezinto zokwenza izinto ezivela endaweni yokukhipha usebenzisa umshini odonsayo. Imvamisa, kunomshini omile, obhekekethekeke amabhakede akhipha impahla oyifunayo ngaphambi kokuyihambisa endaweni yokuhlunga. Ukwehla kwemishini kuvame ukwenziwa eduze nolwandle futhi kusetshenziswa ukuze kususwe ukulahla umhlaba emhlabathini noma ogwini.
I-Hydraulic Dredging
Ngesikhathi sokudonsa kwe-hydraulic, amaphampu(imvamisa amaphampu we-centrifugal)zisetshenziselwa ukususa i-sediment kusuka esizeni esakhiwe. Okuqukethwe kungeniswe kupayipi kusuka phansi kwesiteshi. I-sediment ixubene namanzi ukwenza ingxube ye-mud ukuze kube lula ukulethwa kwepompo. I-Hydraulic Dredging ayinasimithombo eyengeziwe yokuhamba noma imishini njengoba i-sediment ingahanjiswa ngqo esikhungweni se-onshore, ukonga izindleko ezengeziwe nesikhathi.
Imanga-okhalwayo
I-Bio-Dredging ukusetshenziswa kwezinto ezithile (ezinjengama-microorganisms athile, izitshalo zasemanzini) ukubola futhi zilimaze izinto eziphilayo kanye nokuvulisa emanzini amdaka.Isibonelo, ukusetshenziswa kohlelo lweWetland olwakhiwe kungasebenzisa umsebenzi wezitshalo ezimanzi kanye nama-microorganisms ukuze anciphise udaba lwe-organic futhi amise udaba lwamanzi amdaka. Kodwa-ke, akukubizi ukunqwabelana kwezinhlayiya zenhlabathi ezingaphakathi, okungenzeka kube imbangela enkulu yomthwalo wediment kanye nokuncishiswa okujulile emachibini amaningi nasemachibini amaningi. Lezi zinhlobo zama-sedments zingasuswa kuphela ngokusebenzisa imishini yokufaka imishini.
Ama-hoses we-CDSR Dredging angasetshenziswa ku-cutter suction dredger kanye ne-trailing suction hopper dredger
CI-Utter Suck Dredger
I-cutter suction Dredger (CSD) uhlobo olukhethekile lwe-hydraulic dredger.Njenge-dredger emile, i-CSD ifakwe ikhanda elikhethekile lokusika eliphakeme, elisika futhi liphule izinto eziqinile, bese limunca impahla eyenziwe nge-hose yokumunca ekugcineni okukodwa.
I-CSDISesebenza kahle futhi ebiza kakhulu,yonaIngasebenza enanini elihlukahlukene lokujula kwamanzi, futhi amabala abukhali awenza abe alungele zonke izinhlobo zenhlabathi, ngisho namadwala nomhlabathi onzima. Ngakho-ke, isetshenziswa kabanzi kumaphrojekthi amakhulu ohlwitha afana namachweba okujula.
TI-Countur Suction Hopper Dredger
I-trailing suction hopper UDredger (THSD) ungumbhishobhi omkhulu ozenzela u-Dredger onamakhanda ahambisana nekhanda le-trailing kanye ne-hydraulic suction device. Inokusebenza okuhle kwemikhumbi futhi ingazihlola, ukuzilibazisa nokuzilulazela. Le khasiI-CDSR Bow Blowing Hose Set iyingxenye ebalulekile yohlelo lokushaya ngomnsalo ku-trailing suction hopper dredger (THSD). Kubandakanya iqoqo lama-hoses aguqukayo axhumeke ngohlelo lokushaya ngomnsalo ku-TSHD nepayipi elintantayo.
I-TSHD inekhono kakhulu futhi ilungele kahle ukwehla kwezinto zokwakha kanye nenhlabathi ethambile efana nesihlabathi, i-gravel, i-sludge noma ubumba. Ngoba i-TSHD ivumelana nezimo futhi isebenza kahle ngisho nasemanzini anolaka nasezindaweni eziphakeme zasemanzini, ivame ukusetshenziswa ezindaweni ezijulile nasemkhathini wezindinyana zasolwandle.
