Bangladesh iri kupfuura makumi mashanu emakore.Gore rega rega musi wa16 Zvita, Bangladesh inopemberera kusununguka kwayo.Hurumende inoisa mari yakawanda mukukura kwenyika kuitira kuti ivhare gaka rehupfumi nekukasika.Kuvakwa kwezviteshi zvegungwa isarudzo yakajeka.
Padivi pezviteshi zviviri zviripo Mongla neChittagong, yave nguva yekuvaka chiteshi chengarava chechitatu: Payra, chiteshi chengarava chakavakwa kubva pakutanga kuti chiwedzere chinodiwa chiteshi chengarava pamwe nekubvumira ngarava hombe kufona panzvimbo, zvichiramba kudiwa kwekutakurwa kuenda. zvimwe zviteshi zvakaita seSingapore neColombo.
Bhangari remugungwa riri kuvaka mugwagwa wekupinda kune ichi chiteshi chengarava kubva panyika, Jan De Nul nzira yekupinda kubva kugungwa.
"Isu tinosunga chikamu chezvakacheneswa pavhu kuitira kuvandudzwa kwezviteshi zvenguva yemberi.Nezveizvi, tinounganidza ngarava sere dzekuchera, makiromita mazhinji epasi-, kunyura- uye mapaipi anoyangarara uye boka rezvikepe zvidiki kutsigira mabasa, "Jan De Nul akadaro.
Nzvimbo yechiteshi chengarava yakazadzwa nejecha apo panozovakwa materminal.Nzvimbo yacho ine 110 ha.
Nzira yekupinda nayo yakareba makiromita makumi manomwe neshanu uye inomhanya kusvika makiromita makumi mashanu neshanu mugungwa, zvichienderana nenzvimbo chaiyo, yakadzamiswa ingave nekucheka suction dredgers (CSDs) kana trailing suction hopper dredgers (TSHDs).
Iwo ma hopper anorasa jecha mberi kunze kwegungwa kana kuribatanidza pavhu mune dredge dumpsite.
Iwo akachekwa ese akabatana kune mutsara unoyangarara unosvika 2.5 makiromita kureba, kuburikidza iyo dredged zvinhu zvinotakurwa kuenda kunzvimbo chaiyo yekurasa pagungwa.
CSDs midziyo yakamira yekudhonza.Pane imwe nzvimbo yekuchera chaiyo, zvibatiso zviviri zvinodzikiswa, uye spud inopinda pasi pegungwa kuti ichengetedze nzvimbo chaiyo.
Munguva yezviitwa zvekuchera, iyo cutterhead inotenderera pasi pegungwa kubva kune imwe anchore kuenda kune imwe.
Kana mamiriro ekunze asingachabvumiri kuchengetedza spud yakadzikiswa, uye nekudaro dredging haichagone kuenderera mberi, spud inosimudzwa, uye anchor yechitatu inoderedzwa - iyo inonzi dutu-anchor - kuchengetedza chikepe munzvimbo chaiyo. .
