CDSR dredging hoses zivame ukusetshenziselwa ukuthutha isihlabathi, udaka nezinye izinto kumaphrojekthi okumba asogwini, axhunywe kumkhumbi wokudonsa noma izinto zokusebenza ukuze kudluliselwe inhlabathi endaweni eqokiwe ngokumunca noma ukukhipha.Amapayipi okudonsa amanzi adlala indima ebalulekile ekunakekeleni amachweba, ekwakhiweni kobunjiniyela basolwandle, ukugwetshwa kwemifula neminye imikhakha, okuhlinzeka ngokusekelwa okuqinile kokugcina imigudu yamanzi ebushelelezi kanye nokuvikelwa kwemvelo kwamanzi.
Ukubalwa kwemvamisa
Umjikelezo wokudonsa: Umjikelezo wokudonsa ubhekisa esikhawuni sesikhathi esidingekayo ukwenza umsebenzi wokudonsa.Ngokwezici zechweba noma umzila wamanzi kanye nezinguquko ekujuleni kwamanzi, umjikelezo wokudonsa ohambisanayo ngokuvamile uzokwakhiwa.
Ukuhlaziywa kwedatha: Hlaziya izitayela namazinga okwehla kwenhlabathi emachwebeni noma emigwaqweni yamanzi ngokusekelwe kumarekhodi omlando wokuqothuka, idatha ye-hydrological, ukunyakaza kwenhlabathi kanye neminye imininingwane.
Indlela yokudonsa: Ngokuya ngezimpawu zezinto ezibonakalayo kanye nekhono lobuchwepheshe lemishini yokudonsa, khetha indlela efanele yokudonsa kanye nenqubo yokunquma umthamo wephrojekthi nokusebenza kahle kokusebenza.
Umphumela wokubala we-dredging frequency uyinani elilinganiselwe, futhi inani elithile lidinga ukulungiswa ngokusekelwe ezimweni zangempela kanye nezidingo zobunjiniyela.Ngesikhathi esifanayo, ukubalwa kwe-dredging frequency nakho kudinga ukuqapha nokubuyekezwa ngokuqhubekayo ukuze kuqinisekiswe ukuthi izimo zokuzulazula zechweba noma umzila wamanzi ziyahlangabezana nezidingo.
Imvamisa yokudonsa enconyiwe
Iziteshi ezisalungiswa ezingajulile (ezingaphansi kwamafidi angama-20) zingase zilungiswe njalo eminyakeni emibili kuya kwemithathu
Iziteshi ezisalungiswa ezijulile (hhayi ngaphansi kwamafidi angama-20) zingase zilungiswe njalo eminyakeni emihlanu kuya kweyisikhombisa
Izinto ezithinta imvamisa yokudonsa
Imvelo yendawo:Ukuguquguquka kokuma komhlaba olwandle kanye noshintsho ekujuleni kwamanzi kuzodala ukunqwabelana kwezinsalela, ukwakha udaka, izihlabathi zesihlabathi, njll. Isibonelo, izindawo zasolwandle eziseduze nemilomo yemifula zijwayele ukuba nezindawo ezinodaka ngenxa yenani elikhulu lenhlabathi ethuthwa imifula..Ngenkathi ama-sandbar akhiwa kalula olwandle eduze neziqhingi ezisogwini.Lezi zimo zendawo zizoholela ekugcwaleni komgwaqo wamanzi, okudinga ukugujwa njalo ukuze kugcinwe umzila wamanzi ucwebile.
Ukujula okuncane:Ukujula okuncane kubhekisela ekujuleni kwamanzi okuncane okufanele kugcinwe esiteshini noma echwebeni, okuvame ukunqunywa uhlaka lomkhumbi kanye nezimfuneko zokuphepha komkhumbi.Uma ukushona kolwandle kubangela ukujula kwamanzi ukuba kwehle ngaphansi kokujula okuncane, kungase kwandise ubungozi nobunzima bokudlula komkhumbi.Ukuze uqinisekise ukuzulazula nokuphepha kwesiteshi, imvamisa yokudonsa idinga ukuvama ngokwanele ukuze kugcinwe ukujula kwamanzi ngaphezu kokujula okuncane.
Ukujula okungavezwa:Ukujula okungadonswa ukujula okuphezulu kwenhlabathi okungasuswa ngempumelelo ngemishini yokudonsa.Lokhu kuncike emandleni obuchwepheshe bemishini yokudonsa, njengomkhawulo wokujula wokumba we-dredge.Uma ukujiya kwenhlabathi kungaphakathi kwebanga lokujula okwesabekayo, imisebenzi yokudonsa ingenziwa ukuze kubuyiselwe ukujula kwamanzi okufanele.
I-sediment igcwala ngokushesha kangakanani indawo:Izinga inzika egcwala ngalo indawo izinga inzika enqwabelana ngayo endaweni ethile.Lokhu kuncike emaphethini okugeleza kwamanzi kanye nesivinini sokuthutha intlenga.Uma inzika igcwala ngokushesha, ingase ibangele ukuthi isiteshi noma imbobo ingahambeki ngesikhathi esifushane.Ngakho-ke, imvamisa yokudonsa efanele idinga ukunqunywa ngokususelwa kuzinga lokugcwaliswa kwenhlabathi ukuze kugcinwe ukujula kwamanzi okudingekayo.
