Mkeri hangarau
Ko te keri ā-ringa te mahi keri rauemi mai i tētahi wāhi tangohanga mā te whakamahi i tētahi mīhini keri. I te nuinga o te wā, he mīhini tūmau, e anga ana ki te peere, e keri ana i ngā rauemi e hiahiatia ana i mua i te tukunga ki te wāhi whakarōpū. Ko te keri ā-ringa te tikanga e mahia ana i te taha o te takutai moana, ā, e whakamahia ana hei tango i ngā paru i runga i te whenua, i te takutai moana rānei.
Te keri waipēhi
I te wā e keri ana i te waipēhi, ka whakamahia ngā papu(he papu pūwero te nuinga)e whakamahia ana hei tango i te paru mai i te wāhi i keria. Ka mimitihia te rauemi ki roto i te paipa mai i te raro o te awaawa. Ka konatunatua te paru ki te wai hei hanga i te ranunga paru kia māmā ake ai te tuku papu. Kāore e hiahiatia he taputapu kawe, he taputapu rānei mō te keri waipēhi nā te mea ka taea te kawe tika i te paru ki te whare i uta, ka penapena i te whakapaunga me te wā tāpiri.
Koiora-keri
Ko te keri-koiora ko te whakamahinga o ngā rauropi motuhake (pērā i ētahi moroiti iti, ngā tipu wai) hei pirau me te whakapōrearea i ngā matū rauropi me ngā onepū i roto i te wai para.Hei tauira, mā te whakamahi i tētahi pūnaha repo kua hangaia, ka taea te whakamahi i te mahi a ngā tipu repo me ngā moroiti ki te whakangaro i ngā mea rauropi me ngā mea iri i roto i te wai para. Heoi, kāore e aro ki te kohikohinga o ngā matūriki oneone kore-rauropi, koinei pea te tino take o te taumaha paru me te whakahekenga hohonu i roto i te maha o ngā roto me ngā roto. Ka taea anake te tango i ēnei momo paru mā te whakamahi i ngā taputapu keri miihini.
Ka taea te whakamahi i ngā ngongo keri CDSR ki te keri momi tapahi me te keri hopa momi muri.
Cmīhini keri momi tino
Ko te mīhini keri waipēhi tapahi (CSD) he momo mīhini keri waipēhi motuhake.Hei mīhini keri pūmau, kei te CSD tētahi pane tapahi hurihuri motuhake, e tapahi ana, e wawahi ana hoki i ngā paru mārō, kātahi ka ngotea te rauemi kua keri mā te ngongo momi i tetahi pito, ka tukuna tika atu ki te wāhi tuku para mai i te paipa tukunga.
CSDkowhai hua, ā, he iti hoki te utu,reiraka taea te mahi i roto i ngā momo hohonutanga wai whānui, ā, nā ngā mata koi niho e pai ai mō ngā momo oneone katoa, tae atu ki ngā toka me te whenua mārō. Nō reira, he whānuitia te whakamahinga i roto i ngā kaupapa keri nui pēnei i te hōhonutanga o ngā tauranga.
Tte mīhini keri mōmona reera
Te pūwero momi o muri Ko te mīhini keri wai (TSHD) he mīhini keri wai nui e neke ana i a ia anō, kāore e tū, he pane tōmuri me te taputapu momi waipēhi. He pai te mahi whakatere, ā, ka taea e ia te neke i a ia anō, te uta i a ia anō, me te tango i a ia anō. Ko teHuinga Ngongo Pupuhi Pere CDSR He wāhanga nui tēnei o te pūnaha pupuhi ihu o te Trailing Suction Hopper Dredger (TSHD). Kei roto ko tētahi huinga ngongo ngāwari e hono ana ki te pūnaha pupuhi ihu o te TSHD me te paipa mānu.
He tino ngāwari te nekeneke o te TSHD, ā, he pai rawa atu mō te keri i ngā rauemi koretake me ngā oneone ngohengohe pērā i te onepu, te kirikiri, te paru, te uku rānei. Nā te mea he tino ngāwari te TSHD, ā, he pai tana mahi ahakoa i roto i ngā wai pūkeri me ngā wāhi moana e nui ana te haere o te tangata, he maha ngā wā ka whakamahia i roto i ngā taiao wai hohonu me te tomokanga o ngā ara moana.
