Ihamba nama-spuds ngenkathi intanta phezulu. Lokhu kumisa kuvumela umsiki ukuthi aye phambili ekusikeni okulandelayo ngaphandle kokulahlekelwa isikhundla. Lobu buchwepheshe obufanayo futhi buvumela i-dredge ukuthi ihlehle iye emuva ukuze icoshe izinto ezingcolile okungenzeka ukuthi i-dredging iphuthelwe kodwa isalokhu isesimweni esifanayo sokuqhubeka nokudonsa phambili.

Lapho imingcele ejwayelekile isengozini yokulahlekelwa isikhundla sayo ngenxa yemijikelezo, lena ayikho. Azikho izintambo zokusebenzisa ukwakhiwa komzimba futhi ngenxa yalokho azikho izintambo zokufaka izidakamizwa ezingcolile ezibangela ukungasebenzi okungafuneki.

Ezimweni eziningi, ikakhulukazi ezindaweni zemifula, ukungcola akukhona nje kuphela ezinsikeni kodwa futhi nangokufuduka ezindaweni ezinesihlabathi noma zobumba zangempela. Umsiki we-dredge unamandla anele okususa lokhu kungcoliswa kungqimba oluncane. Iyunithi ingasusa izidalwa ekujuleni kwamamitha ayi-22 (7 m) ngaphansi kwamanzi.

Iyunithi inokulawula okutshela opharetha we-dredge kahle ukuthi iyiphi isendlalelo esikuyo. Isisuli singakwazi ukungena ekuvumeleni kwe-inch noma i-intshi eyodwa (25 mm) esibucayi, ikakhulukazi ezincekelweni ezingcolile. Izilawuli zomsebenzisi zigcina ukumiswa kabusha kokudonsela emuva kukholamu yamanzi kube ubuncane ngokuphelele. Yonke imisebenzi ye-dredge ixhumene nezinhlelo zokuma komhlaba jikelele.

Le dredge dredge dredge yemvelo ingukuthuthuka kokuqala okukhulu kusetshenziswa lolu hlobo lobuchwepheshe eminyakeni eminingi. Lawa ama-Ellicott® Ama-Brand Swinging Ladder dredges angasetshenziswa emachibini nasemiseleni emincane njengezinkulungwane zamamayela emisele eFlorida ezodinga ukumbiwa.

Ngenxa yokuthi inqama ephakamisa futhi yehlise isitebhisi ingafaka amandla asezansi kumsiki, iqinisekisa ukuthi umsiki uthintana ngokugcwele nenhlabathi engcolisiwe ngaso sonke isikhathi futhi ayishayisani, okungadala ukungqubuzana okungathandeki.

I-dredge itholakala kokugeleza kokukhipha kwe-1,500 kuya kumalitha we-6,000 / umzuzu (i-5,700 kuya kumalitha / umzuzu we-22,700). Isebenzisana kakhulu nezinqubo zokwelapha udoti ezingcolile ngenxa yamaphesenti anembile okufiphala ohlelweni lwamapayipi ngokufana.

I-dredge iyasebenza kakhulu ukuthi ingenza ukujika kwesobunxele nangakwesobunxele, ibuyise emuva, futhi ipaki elihambisana nayo ngokwayo kufana nokupaka imoto. I-dredge ingaba idizili noma igesi kagesi.
