Cutter Suction Dredger - Iyo Yakasimba Riverine uye Marine Excavator

A Cutter Suction Dredger(CSD) inopfuura ngarava chete; Icho chirimwa chinoyangarara, chakasanganiswa chekuchera chirimwa, chine mukurumbira sechimwe chezvishandiso zvakasiyana-siyana uye zvinoshanda zvemigodhi yepasi pemvura, kugadzirisazve ivhu, uye kudzika kwegwara. Silhouette yayo inoyevedza, ine musoro wakasimba unotenderera wekucheka pamagumo emanera, chiratidzo chehungwaru hwevanhu mukushandisa zviwanikwa zvemvura, kunyanya mukucherwa kwegoridhe nemarata.

Iyo misimboti yekushanda yeCSD ine simba zvinoyevedza. Musoro wekucheka unotenderera, une mazino akaomarara, unosunungura zvinhu zviri pasi pemvura—ringava jecha, ivhu, matombo, kana simende. Panguva imwe chete, pombi dzecentrifugal dzine simba dzinogadzira vacuum, dzichisveta musanganiswa wakasunungurwa (slurry) kuburikidza nepombi yekusveta. Iyi slurry inozotakurwa pamusoro pezvinhambwe zvakati wandei kuburikidza nepombi, kungave kune inogadzirwa chirimwa pamahombekombe kana kunzvimbo yakatarwa yekurasa kana nzvimbo yekudzorera.

Thecutter suction dredger's genius iri mukushanda kwayo nguva dzose. Kusiyana nekubata kana mabucket dredger anoshanda nguva nenguva, iyo CSD inocheka, inosveta, uye inotakura zvinhu mune imwe isina musono, isina-kumira maitiro, zvichikonzera kusingaenzaniswi kugadzirwa kwakanaka. Kufamba kwayo ndechimwe chinhu chakakosha. Uchishandisa sisitimu ye spuds (anchoring piles) uye mawinji, iyo dredger inogona kuzvizunza yega muarc pakatarisana nebasa, nenzira yekujekesa nzvimbo yakafara pasina kudzokororwa.

Muchirevo chekucherwa kwegoridhe, kunyanya murwizi uye offshore placer deposits, iyo CSD inokosha. Inokwanisa kuwana uye kugadzira matara ane goridhe akavigwa pasi pematanho ekuremerwa nemvura, achidyisa slurry kune chirimwa chemuboard kana pasi-based washing plant. MaCSD emazuva ano zvinoshamisa zvekugadzirisa. Iwo anogona kugadzirwa nehurefu hwakasiyana-siyana hwemanera, dhizaini yekucheka misoro yezvinhu zvakasiyana, masimba epombi, uye kunyangwe masisitimu ekumisa masisitimu ekuita chaiko kwemugungwa.

Kubva pakuchengetedza tsinga dzakakosha dzekutengeserana kwepasirese nekudzika zviteshi uye nzira dzekufamba kusvika pakugadzira nyika nyowani kubva kugungwa nekuvhura hupfumi hwezvicherwa zvepasi pemvura,cutter suction dredgerchiratidzo chehunyanzvi hwekugadzira. Inoshanda uko michina yechinyakare inofamba-famba haigone, ichishandura nzvimbo dzakaoma pakati penyika nemvura kuita nzvimbo dzemukana nekufambira mberi.
