Kev Txhim Kho Keeb Kwm ntawm Cutter Suction Dredgers

Thaum Lub Ob Hlis 12, 1998, 1,750-cub-meter cutter suction dredger tau ua tiav thiab xa mus rau Yangtze River Waterway Bureau. Raws li thawj qhov loj -scale cutter suction dredger ntawm nws tus kheej tsim thiab tsim los ntawm kuv lub teb chaws nyob rau hauv lub xyoo pua 20th, nws tau ua tiav cov txheej txheem thoob ntiaj teb ntawm xyoo 1990 thiab tau ua tiav cov thev naus laus zis rau cov nkoj loj, automated engineering nkoj hauv kuv lub tebchaws.
Nyob rau hauv 2006, "Tianshi," kuv lub teb chaws thawj domestically tsim thiab ua loj -scale cutter suction dredger, tau ua tiav xa. Nws cov nqi tsim kho yog kwv yees li ib nrab ntawm cov nkoj xa tuaj, ua rau muaj kev cuam tshuam txawv teb chaws monopoly ntawm cov thev naus laus zis no.
Nyob rau hauv 2010, "Tianjing," kuv lub teb chaws thawj super- tus kheej loj- lub tshuab nqus tsev twj dredger, ua nws debut. Nws nthuav tawm lub zog txiav ntawm 4,200 kW, lub peev xwm ntawm 4,500 cubic meters ib teev twg, thiab qhov siab tshaj tawm qhov deb ntawm 6,000 meters, nruab nrog qhov uas yog qhov muaj zog tshaj plaws excavation system nyob rau hauv Asia.
Xyoo 2019, "Tiankun"-Asia qhov hnyav tshaj plaws -lub luag haujlwm tus kheej- lub tshuab nqus tsev twj dredger- tau ua tiav thiab muab tso rau hauv kev ua haujlwm. Ntsuas 140 meters ntev, nws khav theeb lub zog ntawm 6,600 kW, dredging peev ntawm 6,000 cubic meters ib teev twg, thiab qhov siab tshaj tawm qhov deb ntawm 15,000 meters. Nws pioneered ib tug dual - txoj hauj lwm qhov system combining ib tug steel spud carriage nrog ib tug peb -cable teeb, muab muaj zog adaptability rau hnyav hiav txwv tej yam kev mob thiab incorporating ntau tshaj ib txhiab ywj siab innovation. Tib lub xyoo, "Tianjing" series ntawm cov cuab yeej yeej qhov khoom plig tshwj xeeb ntawm National Science thiab Technology Progress Award rau nws qhov kev ua tiav hauv kev ywj pheej R & D thiab kev lag luam loj ntawm - nplai offshore cutter suction dredging khoom.
Thaum Lub Plaub Hlis 22, 2025, "Junlan"- lub ntiaj teb loj tshaj plaws hluav taws xob tag nrho-tsav, demountable, thiab eco-tus phooj ywg cutter suction dredger- tau nkag mus rau qhov kev pabcuam. Siv qhov sib txawv - zaus hluav taws xob tsav tshuab, nws muaj qhov siab tshaj plaws dredging qhov tob ntawm 25 meters thiab muaj peev xwm ntawm 2,000 cubic meters ib teev twg. Nws ua tiav xoom- carbon emissions thiab muaj peev xwm rau kev ua haujlwm ntse ua haujlwm tsis zoo thiab kev xa tawm sai.
Tsav los ntawm kev ua tiav hauv cov cuab yeej tseem ceeb no, Tuam Tshoj qhov ntim txhua xyoo dredging tau tshaj 1 billion cubic meters, ua rau nws yog lub ntiaj teb cov thawj dredging lub teb chaws.
