Iukunwetshwai-joint iyingxenye ebalulekile ku-dredger exhuma iphampu yokudonsa namapayipi futhi ixhuma amapayipi kudekhi.Inemisebenzi yokuhlinzeka ngokunwetshwa nokufinyela, ukumunca ukushaqeka kanye nokuvikelang kweimishini.Ukukhetha okulungileukunwetshwaokuhlangene kuyisihluthulelo sokuqinisekisa ukusebenza okuvamile kwesistimu kanye nokwenza ngcono ukusebenza kahle komsebenzi.
Izinto okufanele uzicabangele lapho ukhethaukunwetshwa amalunga
Eukunwetshwaamalungazivame ukusetshenziswa ekufuneni izinqubo eziyisisekelo njengalezo ezisezimbonini zensimbi, amandla, i-pulp nephepha, izimayini namakhemikhali.Ukukhetha okufanele, ukufakwa kanye nokugcinwa kweukunwetshwaamajoyinti abalulekile ekuqinisekiseni ukwethembeka kwesistimu yakho yamapayipi kanye nokwandisa ukusebenza ngenkathiukuzuza aimpilo ende yesevisi.
Funda mayelana nesicelo
Isinyathelo sokuqala ekukhetheni ijoyinti elifanele lokunweba ukuthola ukuqonda okuphelele kwezidingo zohlelo lwakho lokusebenza, ucabangela indawo yokusebenza ye-dredger, ingcindezi kanye nebanga lokushisa, kanye nendawo nezidingo zokuxhunywa kwamapayipi, lokhu kuzokusiza ukuthi unqume usayizi. , uhlobo kanye nempahla yejoyinti yokwandisa oyidingayo.
Ukukhetha okubalulekile
Ukukhetha into efanele kuyisihluthulelo sokuqinisekisa ukusebenza nokuhlala isikhathi eside kwejoyinti lokunweba.Izinto ezijwayelekile zifaka irabha, insimbi, ne-polymer.Izinto zenjoloba zinokunwebeka okuhle kakhulu nokumelana nokugqoka, okuyenza ifanelekele izinhlelo eziningi ze-dredger.Izinto zensimbi zinamandla amakhulu nokumelana nokucindezela, futhi zifanele izindawo zokusebenza ezinezidingo zokucindezela okukhulu.
Ukuklama nokumisa
Kubalulekile ukucabangela ukuklama nokucushwa kwejoyinti lokunweba ukuze kube lula ukufakwa nokugcinwa, ukuqinisekisa ukuthi ubude bejoyinti lokunweba elikhethiwe lifanele indawo yokufaka.Ngaphansi kwezimo ezijwayelekile, ubude bejoyinti lesandiso ngokuvamile bufushane ngo-0~5mm kunendawo yokufaka,kanye nokungadingeki kwesikhala sokufakwa kwejoyinti elide lokunwetshwa akudluli ku-10mm.Ukwengeza, uhlobo lwesixhumi esibonakalayo kanye nendlela yokuxhuma yejoyinti lesandiso kufanele futhi kucatshangelwe.Idizayini enhle inganikeza umphumela ongcono wokumunca ukushaqeka futhi ivikele okokusebenza ukuze kuqinisekiswe ukuzinza nokuphepha kohlelo lokusebenza.
Ikhwalithi kanye nokulinganisa
Ukuhlanganiswa kwesandisokufanele ihambisane nezindinganiso zekhwalithi ezifanele kanye nemithetho yemboni futhi yenziwe ngaphansi kwesistimu yokuphatha ikhwalithi ethobela izindinganiso zamazwe ngamazwe ukuze kuqinisekiswe ukusebenza kwazo nokwethembeka.
Khetha umkhiqizi onokwethenjelwa
AnUmkhiqizi onolwazi nochwephesheisisiqinisekiso sekhwalithi engokwezifiso zokwandisa amalunga.I-CDSR inesipiliyoni seminyaka engaphezu kwengama-50 ekwakhiweni nasekukhiqizeni imikhiqizo yenjoloba.Sisesimweni sokuhlinzeka ngekhwalithi ephezulu, imikhiqizo eyenziwe ngezifiso nezixazululo zezidingo zakho zohlelo lokusebenza.
