Amphibious Excavator Yuav Ua Li Cas? Los ntawm River Dredging mus rau Alluvial Kub Mining, Site Configuration txiav txim qhov kev teeb tsa
Thaum cov neeg muas zaub thawj zaug saib amphibious excavator, ib qho ntawm thawj cov lus nug lawv feem ntau nug yog:"Nws ua haujlwm tob npaum li cas hauv dej?"
Tau kawg, dej qhov tob tseem ceeb heev. Tab sis thaum koj nkag mus rau hauv qhov project tiag tiag, muaj ntau lwm yam uas tseem ceeb npaum li cas.
Piv txwv li, peb tau txais cov lus nug los ntawm cov neeg muas zaub uas yooj yim hais tias: qhov project yog nyob rau hauv ib tug dej, dej yog hais txog 4 meters tob, thiab lawv xav siv ib tug amphibious excavator kom tshem tawm cov xuab zeb thiab sediment ntawm tus dej.
Thaum xub thawj siab ib muag, kev xaiv cov cuab yeej zoo li ncaj nraim. Tab sis tom qab nug ob peb nqe lus nug ntxiv, qhov xwm txheej tiag tiag yuav nyuaj dua.
Hom av twg nyob rau ntawm ntug dej? Cov txheej sediment tuab npaum li cas? Puas yog cov khoom siv excavated yuav raug thauj mus rau cov nkoj thauj khoom, thauj los ntawm cov tsheb thauj khoom, lossis siv los ntawm cov kav dej? Ntau npaum li cas cov khoom yuav tsum tau tuav ib hnub?
Rau ib qho kev ua haujlwm kub pob zeb, muaj cov lus nug ntxiv.
Nyob rau hauv rooj plaub no, amphibious excavator tsuas yog pem hauv ntej - cov khoom siv mining kawg. Kev tshuaj ntsuam, ntxuav, thiab cov khoom siv rov qab kub kuj tseem yuav tsum tau nyob hauv qab. Muaj qhov txiaj ntsig me me hauv kev khawb sai yog tias cov txheej txheem ua haujlwm tsis tuaj yeem khaws cia.
Tias yog vim li cas peb ib txwm tsis xaiv amphibious excavator tsuas yog raws li nws cov kev khiav hauj lwm tonnage.Cov xwm txheej ntawm lub xaib tuaj ua ntej.
Dej Dredging: Qhov kev sib tw tiag tiag yog feem ntau nkag mus rau hauv thaj chaw ua haujlwm
Pa excavators muaj peev xwm ua tau rau hauv av. Tab sis thaum lawv ncav cuag dej ntws, tidal flats, los yog cov av nkos, qhov kev txwv loj tshaj plaws feem ntau tsis yog lub cav fais fab. Nws yog seb lub tshuab tuaj yeem nyob ruaj khov thiab txav tau zoo.
Lub ntug dej hiav txwv yuav zoo li cov av ntub dej zoo tib yam, tab sis hauv qab yuav muaj cov av nkos sib sib zog nqus. Thaum ib tug pa tracked excavator nkag mus rau hauv cheeb tsam, cov lem yuav maj mam ntog, ua zog nce nyuaj. Hauv cov dej tidal, hloov cov qib dej ntxiv lwm qhov sib txawv.
Qhov no yog qhov chaw amphibious excavators muaj qhov zoo dua.
Lawv feem ntau siv pontoon-style undercarriages nrog cov cheeb tsam loj los txo cov av siab. Nyob ntawm qhov project, lub tshuab kuj tuaj yeem nruab nrog cov pontoons ywj siab, dav lem, thiab spud systems los txhim kho kev ruaj ntseg hauv cov dej ntiav thiab cov av mos.
Tab sis muaj ib lub ntsiab lus uas yooj yim los saib:
Muaj peev xwm ntab tsis tau txhais hais tias lub tshuab tuaj yeem khawb tau ruaj khov.
Thaum lub boom txuas mus rau sab nraud, excavation kuj tsim ib lub sij hawm tseem ceeb nyob rau hauv pem hauv ntej ntawm lub tshuab. Thaum sib sib zog nqus excavation los yog thaum ua hauj lwm nyob rau hauv compacted xuab zeb thiab gravel, lub tshuab xav tau txaus buoyancy thiab stability.
Qhov no yog vim li cas ib qho amphibious excavator yuav tsum tsis txhob raug xaiv los ntawm kev saib nws "qhov siab tshaj plaws ua haujlwm."
Qhov project tiag tuaj yeem qhia peb ntau
Heathcote River dredging project hauv New Zealand yog ib qho piv txwv zoo.
Nyob nruab nrab ntawm xyoo 2018 thiab 2020, 30- tuj-chav Hitachi amphibious excavator tau siv rau kev tshem tawm cov dej khib nyiab. Cov ntaub ntawv muaj nyob rau pej xeem qhia tias kwv yees li70,000 tons ntawm sedimentraug tshem tawm thaum kawg.
Ib qho kev nthuav dav ntawm qhov project no tshwj xeeb yog tsim nyog sau cia.
Lub amphibious excavator yog lub luag hauj lwm rau excavating sediment los ntawm tus dej, tab sis qhov project tsis tas thaum cov khoom raug excavated. Raws li thaj chaw ua haujlwm tau txav mus rau sab saud, kev thauj mus los raws ntug dej tau hloov pauv, thiab cov nkoj tseem yuav tsum tau thauj cov khoom siv dredged.
Hauv lwm lo lus, amphibious excavator daws qhov teeb meem ntawmnkag mus rau thaj chaw ua haujlwm thiab nqa tawm excavation.
Nws tsis tuaj yeem daws qhov teeb meem ntawm qhov chaw khawb av yuav mus, nws yuav thauj mus li cas, lossis yuav ua li cas thaum kawg yuav pov tseg.
Nov yog qee yam peb feem ntau hais txog thaum tsim cov khoom siv daws teeb meem:lub excavator thiab ua tiav dredging system yog ob yam sib txawv.
Yog tias ib qhov project xav tau los daws ntau pua lossis ntau txhiab tus cubic meters ntawm cov khoom siv ib hnub, tsom mus rau lub excavator tsuas yog tuaj yeem tsim kom muaj lub tog raj kheej hauv kev thauj mus los.
Rau kev khawb tob, qhov ntev dua Boom tsis yog ib txwm zoo dua
Lwm qhov piv txwv tseem ceeb yog qhov ntiav - dej hauv Fab Kis txuas nrog tus dej Seine.
Cov ntaub ntawv pej xeem qhia tias kwv yees li 20-tuj-chav BAE200 amphibious excavator tau siv rau qhov project. Kev ua haujlwm tau siv sijhawm yim lub lis piam, nrog kwv yees li12,000 m³ ntawm cov khoom siv xuab zebtshem tawm. Qhov siab tshaj plaws ua hauj lwm qhov tob mus txog6 meters hauv qab dej.
Lub tshuab tau nruab nrog sab pontoons thiab spuds los txhim kho kev ruaj ntseg.
Muaj qhov ua tau zoo heev thaum ua haujlwm ntawm qhov tob dua: kev ua haujlwm ntev dua ua rau lub vojvoog khawb, tab sis nws kuj ua rau lub sijhawm ua haujlwm ntawm lub tshuab.
Yog li, yog tias tus neeg siv khoom qhia rau tus neeg tsim khoom:
"Kuv yuav tsum tau khawb 6 meters tob."
Cov lus teb tsis tuaj yeem tsuas yog:
"Tom qab ntawd peb yuav nruab ib lub boom ntev dua."
Lub tshuab ua haujlwm hnyav, qhov ntev pontoon, ntev spud, hydraulic system, thiab qhov tseeb excavation kuj yuav tsum tau xav txog.
Excavating soft sediment kuj txawv heev ntawm excavating ib tug dej hauv qab uas muaj ntau cov xuab zeb, gravel, los yog cobbles.
Yog li ntawd,kev ua haujlwm qhov tob yog qhov tshwm sim ntawm tag nrho cov cuab yeej teeb tsa, tsis yog qhov ntsuas uas yuav tsum tau txiav txim siab cais.
Dab tsi hloov thaum qhov project yog Alluvial Gold Mining?
Rau cov dej dredging, lub hom phiaj tseem ceeb yog feem ntau tshem tawm cov av.
Rau alluvial kub mining, lub hom phiaj yog txawv.
Cov lus nug tsis yog tsuas yog ntau npaum li cas cov khoom tuaj yeem khawb tau. Cov lus nug tseem ceeb dua yog qhov muaj nuj nqis npaum li cas hauv cov khoom siv ntawd thiab seb cov txheej txheem ua haujlwm hauv qab tuaj yeem rov qab tau zoo.
Alluvial kub mining yog txawv ntawm hard- pob zeb kub mining.
Tom qab ntev - huab cua huab cua thiab kev thauj mus los los ntawm cov dej ntws, cov kub tuaj yeem sib xyaw ua ke nrog cov xuab zeb, pob zeb, cobbles, thiab av nkos hauv cov dej hauv qab, dej nyab, lossis cov dej qub.
Ib qho amphibious excavator tuaj yeem siv ua pem hauv ntej- cov cuab yeej mining kawg kom nkag mus rau hauv qhov ntiav - thaj chaw dej uas cov neeg siv khoom siv niaj hnub tuaj yeem tawm tsam kom ncav cuag thiab khawb kub -cov xuab zeb thiab pob zeb.
Tab sis excavation tsuas yog thawj kauj ruam.
Cov khoom siv ib txwm xav tau los ntawm kev tshuaj ntsuam xyuas, ntxuav, thiab lub ntiajteb txawj nqus concentration.
Piv txwv li, ib qhov project tsim los ua 500 tonnes ntawm cov khoom nyob rau ib hnub yuav xav tau ib tug sib txawv pem hauv ntej-kawg thiab kev teeb tsa los ntawm ib qhov project aiming 1,500 tonnes ib hnub twg.
Qhov kub particle loj kuj tseem ceeb.
Ib qho kev tso nyiaj uas muaj cov kub ntxhib feem ntau tsis ua tiav raws nraim li ib qho uas muaj feem ntau ntawm cov kub zoo.
Yog li ntawd, thaum tsim kho cov khoom siv pob zeb kub, peb xav paub ntau ntxiv txog seb tus neeg siv khoom puas muaj cov qauv ntxhia, cov txiaj ntsig kev soj ntsuam, cov ntaub ntawv kub -cov ntaub ntawv loj, lossis kev xeem dhau los- cov txiaj ntsig ua tiav dua li tsuas yog nug seb "muaj kub" ntawm qhov chaw.
Ib txoj haujlwm Colombian qhia txog lwm yam khoom siv sib xyaw
Ib qho piv txwv ncaj qha los ntawm qhov project alluvial kub mining hauv Colombia.
Qhov project tau siv Caterpillar amphibious excavator nruab nrog DragflowHY50 hydraulic twj tso kua mis thiab DTM50 dredging taub haumounted rau ntawm tes ua haujlwm.
Txoj kev no yog qhov txawv ntawm cov khoom siv thoob dej yug ntses.
Tom qab nkag mus rau tus dej, lub excavator tsis tsuas yog rub cov khoom rau hauv lub thoob. Xwb, lub excavator hydraulic system powers cov khoom siv hauv qab dej dredging, cia xuab zeb, gravel, thiab slurry yuav tsum tau dredged thiab thauj.
Nyob rau hauv cov nqe lus ntawm cov khoom configuration, lub system yeej tseem ceeb ua ib tug me me underwater mining system:
Amphibious undercarriage + excavator hydraulic system + underwater dredging taub hau + hydraulic twj tso kua mis + tso pipeline.
Hom kev npaj no tuaj yeem pab tau rau cov dej ntiav ntiav thiab cov chaw mining nyob raws li tus ciam teb ntawm av thiab dej.
Nws tuaj yeem yog qhov txaus nyiam tshwj xeeb hauv cov chaw uas lub nkoj loj kub dredging tsis tuaj yeem nkag mus rau thaj chaw mining tau yooj yim.
Yuav tsum Amphibious Excavator siv lub thoob lossis lub twj tso kua mis Dredging?
Yog tsis muaj universal teb.
Yog tias daim ntawv thov tseem ceeb yog dej dredging, xuab zeb excavation, los yog earthmoving raws ntug dej, ib lub thoob feem ntau yog qhov yooj yim tshaj kev xaiv.
Yog hais tias cov slurry excavated yuav tsum tau thauj mus tas li mus rau ntug dej, los yog nquag thauj khoom thiab unloading yog tsis yooj yim, ib tug hydraulic dredging twj yuav tsim nyog xav txog.
Rau alluvial kub mining, downstream processing system kuj yuav tsum tau xav txog.
Ib qho txheej txheem sib xws yog:
Amphibious excavator → Excavation ntawm kub - bearing xuab zeb thiab gravel → Pub → Trommel los yog vibrating screen → Ntxuav → Lub ntiajteb txawj nqus concentration → Kub concentrate rov qab
Lwm qhov kev npaj ua tau yog:
Amphibious excavator → Underwater dredging taub hau → Hydraulic slurry twj tso kua mis → Discharge pipeline → Tshuaj ntsuam xyuas thiab ntxuav → Gravity concentration
Tsis yog qhov system yuav zoo dua.
Thawj txoj hauv kev yog ze dua rau kev khawb cov pa, thaum qhov thib ob yog qhov tsim nyog rau cov haujlwm uas xav tau kev thauj mus los txuas ntxiv slurry.
Qee qhov project yeej tsis haum rau Amphibious Excavators
Qhov no yog ib yam uas feem ntau saib tsis taus.
Yog tias thaj chaw mining yog qhov sib sib zog nqus thiab xav tau ntev -lub sijhawm, txuas ntxiv, siab - ntim ntau lawm, amphibious excavator yuav tsis yog qhov tsim nyog tshaj plaws.
Piv txwv li, nyob rau hauv lub pas dej loj lossis dej tob uas cov cuab yeej yuav tsum nyob twj ywm rau lub sijhawm ntev thaum ua haujlwm txuas ntxiv loj - nplai dredging lossis mining, tus kws tshaj lij dredger, kub mining nkoj, lossis lub nkoj nqus dej yuav yog qhov kev xaiv zoo dua.
Ntawm qhov tod tes, yog tias thaj chaw mining muaj feem ntau ntawm cov dej ntiav, tej zaum nyob ib ncig ntawm 1-3 meters tob, tsis muaj ciam teb meej ntawm tus dej thiab thaj av ib puag ncig, amphibious excavator yuav hloov tau ntau dua.
Qhov no yog vim li cas peb ib txwm tsis txiav txim siab ua ntej ntawd"tus neeg siv khoom yuav tsum siv amphibious excavator."
Peb thawj zaug yuav tsum nkag siab txog cov xwm txheej ntawm qhov chaw thiab tom qab ntawd txiav txim siab seb puas yog amphibious excavator yog qhov kev daws teeb meem tiag tiag.
Cov ntaub ntawv uas tus neeg tsim khoom xav tau tiag tiag yog ntau dua li dej tob
Yog tias koj tab tom npaj yuav los yog kho lub amphibious excavator, nws yog qhov zoo tshaj los muab cov ntaub ntawv ntau npaum li qhov ua tau.
Piv txwv li:
Qhov dej siab tshaj plaws
Dej dav
Yuav tsum tau khawb qhov tob
Thickness ntawm sediment los yog ore txheej
Riverbed av tej yam kev mob
Approximate xuab zeb, gravel, thiab cobble loj
Cia siab tias txhua hnub ua ntim
Cov sijhawm ua haujlwm txhua hnub
Kev thauj mus los deb rau cov khoom siv excavated
Seb puas yuav tsum tau muaj lub raj xa dej tawm
Seb yuav tsum muaj hydraulic dredging twj tso kua mis
Seb cov khoom siv ntxhua khaub ncaws thiab cov ntxhia ua haujlwm twb muaj lawm
Rau qhov kev ua haujlwm ntawm cov pob zeb kub pob zeb, kev txheeb xyuas cov pob zeb hauv av, qhov loj me me, thiab kev sim ua dhau los- cov txiaj ntsig ua tau zoo heev.
Cov ntsiab lus no yuav zoo li me me, tab sis lawv tuaj yeem cuam tshuam ncaj qha rau cov khoom siv.
Piv txwv li, ob txoj haujlwm yuav tsum tau ua 1,000 tonnes ntawm cov khoom ib hnub. Yog tias ib qho kev tso nyiaj feem ntau muaj cov xuab zeb zoo thaum lwm qhov muaj ntau cov pob zeb ntxhib thiab cobbles, pem hauv ntej - cov khoom siv kawg, kev tshuaj ntsuam xyuas, thiab cov nroj tsuag ntxhua yuav xav tau kev teeb tsa sib txawv kiag li.
Tus nqi tiag tiag ntawm Amphibious Excavator tsis yog "ua haujlwm ntawm av thiab dej"
Yog tias koj tsuas saib cov khoom lag luam, "amphibious" suab yooj yim.
Tab sis hauv qhov project tiag tiag, cov cuab yeej siv daws teeb meem ntau dua:
Nws tso cai rau cov khoom siv excavation nkag mus rau thaj chaw uas cov khoom siv tsis tuaj yeem ua haujlwm tau zoo.
Rau cov dej dredging, nws tuaj yeem nkag mus rau hauv dej ntiav thiab cov av nkos.
Rau tidal- kev tsim vaj tsev tiaj tus, nws tuaj yeem txo qhov kev xav tau ntawm kev nkag mus dav dav - txoj kev thiab hauv av npaj.
Rau kev ua haujlwm ntub dej, nws tuaj yeem nruab nrog cov ntawv txuas xws li rub lossis cov nroj tsuag hauv dej.
Rau qhov ntiav - dej xuab zeb mining, nws tuaj yeem ua rau pem hauv ntej - cov khoom siv khawb av kawg.
Rau alluvial kub mining, nws tuaj yeem ua ke nrog hydraulic dredging twj, tshuaj ntsuam xyuas, thiab cov khoom siv lub ntiajteb txawj nqus los tsim kom muaj kev ua tiav ntau dua thiab rov ua haujlwm.
Tab sis cov haujlwm sib txawv tsis xav tau tib yam "tus qauv amphibious excavator."
Ib qhov project dredging tej zaum yuav tsom ntau dua rau excavation efficiency thiab cov khoom thauj.
Ib qhov dej tidal- qhov project ca yuav ua rau muaj kev cuam tshuam ntau dua rau hauv av siab thiab kev txav mus los.
Ib txoj haujlwm khawb tob yuav tsum tau ua tib zoo saib xyuas kom ruaj khov thiab ua haujlwm tob.
Ib txoj haujlwm kub alluvial yuav tsum xav txog ob qho tib si pem hauv ntej - kawg mining peev thiab downstream mineral processing peev.
Yog li, yog tias ib tug neeg tsuas qhia rau tus neeg tsim khoom:
"Kuv xav tau amphibious excavator."
Cov ntaub ntawv ntawd tsis txaus.
Cov ntaub ntawv tseem ceeb tshaj yog:
Nws yuav ua haujlwm qhov twg? Nws yuav excavate dab tsi? Qhov tob npaum li cas? Cov khoom siv ntau npaum li cas yuav tsum tau ua txhua hnub? Thiab yuav ua li cas rau cov khoom tom qab khawb?
Thaum cov lus nug no meej meej, cov chaw tsim khoom tuaj yeem txiav txim siab qhov tsim nyog excavator tonnage, pontoon qhov ntev, cov khoom siv ua haujlwm, kev ruaj khov, lub thoob lossis lub twj tso kua mis dredging, thiab kev tshuaj ntsuam qis qis lossis cov khoom siv ntxhia.
Rau dej dredging, tidal- kev tsim vaj tsev tiaj tus, thiab ntiav - dej alluvial kub mining, amphibious excavator tsis yog ib qho excavator uas "mus rau hauv dej."
Ntau qhov tseeb, nws yog aav-thiab-dej engineering platform uas tuaj yeem teeb tsa raws li qhov chaw tiag tiag.
Thiab thaum xaiv cov khoom siv, cov txheej txheem yuav tsum ib txwm pib nrog covqhov project site thiab tej yam kev mob ua hauj lwm -tsis nrog lub tshuab qauv.
