Xyoo 2002, Txoj Kev Sab Hnub Tuaj ntawm South-rau-North Water Diversion Project tau pib ua haujlwm, thiab nws tau npaj yuav hloov 14.8 billion cubic meters dej hauv ib xyoos tom qab ua tiav.Raws li tag nrho cov phiaj xwm, qhov kawg ntawm kev hloov dej ntawm qhov dej ntws ntawm South-rau-North Water Diversion Project yog 44.8 billion cubic meters, nrog rau 14.8 billion cubic meters rau sab hnub tuaj kab, 13 billion cubic meters ntawm nruab nrab kab, thiab 17 billion cubic meters. meters nyob rau sab hnub poob kab.Lub sijhawm tsim kho yuav siv li 40 txog 50 xyoo.Tom qab qhov project tiav lawm, Nws yuav tsim cov chaw nres tsheb loj tshaj plaws hauv lub ntiaj teb.
Txoj Haujlwm Kev Hloov Dej Sab Qab Teb mus rau Sab Qab Teb yog hloov dej los ntawm sab qab teb mus rau sab qaum teb.Nws hloov dej los ntawm qhov siab qis mus rau qhov siab siab.Yuav kom kov yeej lub zog ntawm lub ntiajteb txawj nqus, nws yog ib qho tsim nyog yuav tau siv ib yam dab tsi zoo li lub twj tso kua mis dej.Yuav kom ua tiav cov dej hloov ntim ntawm kaum tawm lab lab cubic meters, nws yuav siv pes tsawg lub twj tso kua mis?
Txoj Haujlwm Kev Hloov Dej Sab Qab Teb mus rau Sab Qab Teb yog muab faib ua peb kab, sab hnub tuaj thiab sab hnub poob.Txoj haujlwm sab hnub tuaj yog kos los ntawm qhov qis dua ntawm tus Dej Yangtze thiab thauj los ntawm Beijing-Hangzhou Grand Canal.Tag nrho cov chaw nres tsheb dej hauv txoj kab no tau mus txog 51: thawj theem ntawm txoj haujlwm hauv xyoo 2014. Muaj 21 lub chaw nres tsheb, 13 qhov chaw nres tsheb ntxiv yuav tsim nyob rau theem ob, thiab 17 qhov chaw ntxiv yuav tsim nyob rau theem peb.
Cov twj no loj npaum li cas?
Nws tau tshaj tawm tias lub twj tso kua dej me tshaj plaws yog li ib meter siab, thaum lub twj tso kua mis loj tshaj plaws yog 5.2 meters siab, thiab cov twj tso kua mis tau mus txog 13,000 cubic meters, uas yog qhov zoo heev, uas tseem txhais tau hais tias kev ua haujlwm cuam tshuam yog qhov nyuaj heev. .
Rau txoj kab nruab nrab, qhov pib ntawm txoj kab nruab nrab yog Danjiangkou Reservoir, uas yog li 100 meters siab tshaj Beijing, thiab cov dej tuaj yeem ntws los ntawm nws tus kheej los ntawm lub ntiajteb txawj nqus.
Qhov nyuaj tshaj plaws ntawm peb txoj kab yog txoj haujlwm sab hnub poob, uas yog txhawm rau tso dej rau thaj chaw qhuav nyob rau sab hnub poob thiab sab hnub poob los ntawm kev hloov dej los ntawm Dadu River.Cov xwm txheej hauv thaj av sab hnub poob yog qhov hnyav, thiab nws nyuaj heev rau kev ua haujlwm.Hmoov zoo, qhov siab ntawm sab hnub poob pem hauv ntej yog qhov siab, yog li nws yooj yim rau kev tso dej, tab sis nws nyuaj dua los tso dej.
Kev xaiv twj tso kua mis yog qhov tseem ceeb tshaj plaws thiab lub luag haujlwm tseem ceeb hauv "txoj kev kawm ua tau zoo" ntawm kev tsim cov chaw nres tsheb.Txawm hais tias qhov kev xaiv ntawm cov twj tso kua dej yog tsim nyog los yog tsis muaj feem xyuam rau tag nrho cov kev khiav hauj lwm lub taub hau, tshwj xeeb tshaj yog cov kev lag luam nyob rau hauv lub tsim lub taub hau mob, muaj feem xyuam rau cov kev nyab xeeb thiab kev cia siab ntawm tag nrho cov kev khiav hauj lwm lub taub hau, thiab kuj muaj feem xyuam rau installation, txij nkawm, thiab project peev. .
Kev xaiv cov twj tso kua dej muaj xws li kev xav txog kev tsim qauv, tab sis qhov tseem ceeb ntawm kev sib piv thiab xaiv cov yam ntxwv hydraulic.Los ntawm kev sib raug zoo ntawm lej, tuav cov yam ntxwv ntawm lub twj tso kua mis thiab twj tso kua mis kev ua haujlwm, qhov tseem ceeb NPSH, thiab lwm yam, thiab xaiv lub twj tso kua mis tsim nyog tshaj plaws ntawm cov twj tso kua mis uas twb muaj lawm, uas yog qhov tsim nyog rau kev siv nyiaj ntau tshaj plaws.Rau cov chaw nres tsheb, cov dej ntws thiab cov twj tso kua mis kuj tseem ceeb heev.Lub twj tso kua mis yog qhov txuas ntxiv ntawm lub twj tso kua dej, thiab nws yog "dej twj tso kua mis".Nws yog ib qho tsim nyog yuav tsum tuav cov yam ntxwv ntawm cov dej ntws thiab cov twj tso kua mis los ntawm kev sib raug zoo ntawm kev ua lej, thiab xaiv qhov tsim nyog.
Ruite twj tso kua mis muaj pab pawg kws tshaj lij los pab koj xaiv lub twj tso kua mis zoo rau koj qhov chaw thov.
