CDSR dredging hoses zidla ngokusetyenziselwa ukuthutha isanti, udaka kunye nezinye izinto kwiiprojekthi zokugrumba elunxwemeni, eziqhagamshelwe kwinqanawa yokutsala okanye izixhobo zokuhambisa intlenga kwindawo echongiweyo ngokufunxa okanye ukukhupha.Imibhobho yokukhupha amanzi idlala indima ebalulekileyo kugcino lwezibuko, ulwakhiwo lobunjineli baselwandle, ukudilizwa kwemilambo kunye namanye amabala, ukubonelela ngenkxaso eyomeleleyo yokugcina iindlela zamanzi ezigudileyo kunye nokhuseleko lokusingqongileyo lwamanzi.
Ukubala rhoqo
Umjikelo wokutsala: Umjikelo wokutsala ubhekisa kwixesha lekhefu elifunekayo ukwenza umsebenzi wokutsala.Ngokweempawu zezibuko okanye umzila wamanzi kunye notshintsho kubunzulu bamanzi, umjikelo ohambelanayo wokutsala uya kwenziwa ngokubanzi.
Uhlalutyo lwedatha: Hlalutya iintsingiselo kunye namazinga e-sedimentation kumazibuko okanye kwimizila yamanzi ngokusekwe kwiirekhodi zembali zokugrumba, idatha ye-hydrological, intshukumo yentlenga kunye nezinye iinkcukacha.
Indlela yokucoca: Ngokweempawu zezinto eziphathekayo kunye nobuchule bobugcisa besixhobo sokutsala, khetha indlela efanelekileyo yokumisa kunye nenkqubo yokumisela umthamo weprojekthi kunye nokusebenza kakuhle.
Isiphumo sokubala sokutsalwa rhoqo lixabiso eliqikelelweyo, kwaye ixabiso elithile lifuna ukulungiswa ngokusekwe kwiimeko zokwenyani kunye neemfuno zobunjineli.Kwangaxeshanye, ukubalwa kwe-dredging frequency kukwafuneka ukuba kubekwe iliso rhoqo kwaye kuhlaziywe ukuze kuqinisekiswe ukuba iimeko zokukhangela kwizibuko okanye kwindlela yamanzi ziyahlangabezana neemfuno.
Kucetyiswa ukubaleka rhoqo
Imijelo eyilwayo enganzulwanga (ngaphantsi kweenyawo ezingama-20) inokwenza ulungiso rhoqo emva kweminyaka emibini ukuya kwemithathu
Imijelo eyilwayo enzulu (engekho ngaphantsi kweenyawo ezingama-20) inokungena kulondolozo rhoqo emva kweminyaka emihlanu ukuya kwesixhenxe
Izinto ezichaphazela i-dredging frequency
Ubume bejografi:Ukudityaniswa komgangatho wolwandle kunye notshintsho kubunzulu bamanzi kuya kubangela ukufumba kwentlenga, ukwenza intlenga, iintlabathi, njl..Ngelixa imivalo yesanti yenziwa lula elwandle kufutshane neziqithi eziselunxwemeni.Ezi meko zejografi ziyakukhokelela ekudibaneni komgaqo wamanzi, oko kufuna ukugruthwa rhoqo ukuze kugcinwe umgaqo wamanzi ucocekile.
Ubunzulu obuncinane:Ubunzulu obuncinane bubhekiselele kubunzulu obuncinane bamanzi ekufuneka bugcinwe kumjelo okanye izibuko, obudla ngokumiselwa yidrafti yenqanawa kunye neemfuno zokhuseleko lokuhamba.Ukuba intlenge yolwandle ibangela ukuba ubunzulu bamanzi buwele ngaphantsi kobunzulu obuncinane, kunokunyusa imingcipheko kunye nobunzima bokuhamba kwenqanawa.Ukuze kuqinisekiswe ukuhambahamba kunye nokhuseleko lomjelo, ukuphindaphinda kwe-dredging kufuneka kube rhoqo ngokwaneleyo ukugcina ubunzulu bamanzi ngaphezu kobunzulu obuncinci.
Ubunzulu obunokukhutshwa:Ubunzulu obunokukhutshwa bubunzulu obukhulu bentlenga obunokususwa ngokufanelekileyo ngezixhobo zokucoca.Oku kuxhomekeke kubuchule bobugcisa besixhobo sokutsala, njengokumba ubunzulu bomda we-dredge.Ukuba ubungqingqwa bentlenga bungaphakathi koluhlu lobunzulu obunobunzima, imisebenzi yokwehliswa inokwenziwa ukubuyisela ubunzulu bamanzi obufanelekileyo.
Intlenga iyizalisa ngokukhawuleza kangakanani indawo:Umlinganiselo wentlenga ewuzalisa ngayo ummandla liqondo apho intlenga iqokelelana kwindawo ethile.Oku kuxhomekeke kwindlela yokuhamba kwamanzi kunye nesantya sothutho lwentlenga.Ukuba intlenga igcwala ngokukhawuleza, inokubangela ukuba umjelo okanye isibuko singahambeki ngexeshana elifutshane.Ke ngoko, i-frequency dredging frequency ifuna ukumiselwa ngokusekwe kwireyithi yokuzaliswa kwentlenga ukugcina ubunzulu bamanzi obufunekayo.
