Cutter Suction Dredger - Wofukula Mtsinje Wamphamvu ndi Marine

A Cutter Suction Dredger(CSD) ndiyoposa ngalawa; ndi malo oyandama oyandama, ophatikizika, odziwika ngati zida zosunthika komanso zogwira ntchito bwino pakukumba pansi pamadzi, kukonzanso nthaka, ndi kuzama kwa ngalande. Kaonekedwe kake kowoneka bwino, kokhala ndi mutu wodulira wokhazikika kumapeto kwa makwerero, ndi chizindikiro cha luntha laumunthu pogwiritsa ntchito zinthu zapansi pamadzi, makamaka pamigodi ya golide ndi malata.

Mfundo yogwiritsira ntchito CSD ndi yamphamvu kwambiri. Mutu wodulira wozungulira, wokhala ndi mano olimba, umamasula ndi makina zinthu zapansi pamadzi, kaya ndi mchenga, dongo, miyala, kapena zomangira simenti. Panthawi imodzimodziyo, mapampu amphamvu a centrifugal amapanga vacuum, kuyamwa chosakaniza chosungunuka (slurry) kupyolera mu chitoliro choyamwa. Dothi lotereli limasamutsidwa mtunda wautali kudzera papaipi, kupita kumalo opangira zinthu m'mphepete mwa nyanja kapena kumalo osankhidwa kuti atayirepo kapena kukonzanso.

Thechocheka choyamwa'Nzeru zagona pakugwira ntchito mosalekeza. Mosiyana ndi grab kapena dredgers zomwe zimagwira ntchito mosadukizadukiza, CSD imadula, kuyamwa, ndikunyamula zinthu mwanjira imodzi yopanda msoko, yosayima, zomwe zimapangitsa kuti pakhale kupanga kosayerekezeka. Kuyenda kwake ndi chinthu china chofunikira. Pogwiritsa ntchito makina opangira ma spuds (milu yozikika) ndi ma winchi, chowotcha chimatha kudzigudubuza mu arc kudutsa nkhope yogwirira ntchito, ndikuchotsa malo ambiri popanda kuyikanso pafupipafupi.

Pankhani ya migodi ya golide, makamaka m'mitsinje ndi m'mphepete mwa nyanja, CSD ndiyofunikira. Imatha kulowa ndikukonza malo okhala ndi golidi wokwiriridwa pansi pazambiri zolemetsa ndi madzi, kudyetsa matopewo kumalo ochapira omwe ali pamtunda kapena pamtunda. Ma CSD amakono ndi zodabwitsa zakusintha mwamakonda. Atha kupangidwa ndi utali wosiyanasiyana wa makwerero, mapangidwe amutu ocheka azinthu zosiyanasiyana, mphamvu zamapope, komanso makina oyika bwino pamachitidwe enieni apanyanja.

Kuchokera pakusunga njira zofunika kwambiri zamalonda zapadziko lonse lapansi pokulitsa madoko ndi njira zoyendera mpaka kupanga malo atsopano kuchokera kunyanja ndikutsegula chuma chamchere pansi pamadzi,chocheka choyamwandi umboni wa luso lopangidwa. Imagwira ntchito pomwe makina osuntha amtundu wanthawi zonse sangathe, kutembenuza malo ovuta pakati pa nthaka ndi madzi kukhala madera a mwayi ndi kupita patsogolo.
