Tus nqi ntws txiav txim siab pes tsawg litres dej ib lub twj tso kua mis tuaj yeem xa tuaj rau ib ob. Qhov tsawg kawg nkaus ntsuas tus nqi yuav tsum tsis pub tsawg tshaj 10L / s, thiab qhov siab tshaj qhov ntsuas ntws yuav tsum tsis pub tshaj 320L / s.
(2) Lub taub hau (H):
Lub zog nce ib chav tsev hnyav ntawm cov kua tom qab dhau los ntawm lub twj tso kua mis, ntsuas hauv meters. Lub taub hau txiav txim siab qhov siab uas lub twj tso kua mis tuaj yeem thawb dej.
(3) Traffic kev ua tau zoo nkhaus
① Lub zog ntawm tus neeg tsav tsheb nruab nrog lub twj tso kua mis yuav tsum ua kom tau raws li lub zog yuav tsum tau ua rau kev ua haujlwm ntawm txhua qhov chaw ntawm lub taub hau kev ua haujlwm nkhaus ntawm lub twj tso kua mis xaiv.
② Lub taub hau kev ua haujlwm nkhaus yuav tsum yog qhov nkhaus du yam tsis muaj qhov cuam tshuam los yog cov ntsiab lus inflection. Lub siab ntawm xoom ndlwg yuav tsum tsis pub tshaj 140% ntawm tus qauv tsim kev ua haujlwm siab, thiab yuav tsum siab tshaj 120% ntawm tus qauv tsim ua haujlwm siab.
③ Thaum lub qhov hluav taws xob ntws tawm yog 150% ntawm tus qauv tsim tus nqi, lub qhov hluav taws xob siab yuav tsum tsis txhob qis dua 65% ntawm qhov tsim ua haujlwm siab.
④ Thaum tus nqi ntws qis qis tshaj plaws, qhov siab tshaj plaws yog qhov siab tshaj plaws, thiab cov txheej txheem sib khi thiab cov khoom siv ntawm lub twj tso kua mis yuav tsum ua kom tau raws li qhov yuav tsum tau ua rau kev ua haujlwm ntawm lub twj tso kua mis hluav taws xob ntawm qhov qis qis.
4, Qhov yuav tsum tau ua rau kev teeb tsa ntawm cov twj tua hluav taws
(1) Qhov yuav tsum tau ua rau kev teeb tsa cov twj tso kua dej tua hluav taws
① Tus naj npawb ntawm cov twj tso kua mis hauv pawg ua haujlwm Cov qauv ntawm cov twj tso kua dej hluav taws hauv tib lub twj tso kua mis rau cov dej tua hluav taws yuav tsum zoo ib yam, thiab ib pawg ntawm cov twj ua haujlwm yuav tsum tsis pub tshaj 3.
② Cov twj siv hluav taws xob rov qab yuav tsum tau nruab nrog cov twj tso kua mis rov qab, nws qhov kev ua tau zoo yuav tsum ua raws li cov twj tso kua mis ua haujlwm, tshwj tsis yog cov vaj tse hauv qab no: cov tsev nyob nrog qhov siab tsawg dua 54m thiab cov tsev uas muaj cov dej tua hluav taws sab nraum zoov tsim cov dej ntws tsawg dua. los yog sib npaug li 25L / s; Cov tsev uas muaj hluav taws kub hauv tsev tsim cov dej ntws tsawg dua lossis sib npaug li 10L / s.
(2) Kev sib txuas thiab sib txuas ntawm cov twj tua hluav taws
① Serial settingCov kev sib txuas ntawm cov twj tua hluav taws yog txuas ncaj qha rau lub qhov hluav taws xob ntawm ib lub twj tso kua mis mus rau cov yeeb nkab nqus ntawm lwm lub twj tso kua mis thiab ua haujlwm ob lub twj tso kua mis ib txhij. Cov kev sib txuas ntawm cov twj tua hluav taws tuaj yeem ua rau lub taub hau nce ntxiv thaum tus nqi ntws mus tas li.
Muaj ob qhov xwm txheej rau kev sib txuas cov twj tua hluav taws hauv series: ib qho yog txuas lub twj tua hluav taws hauv chav hluav taws nrog lub tank hloov dej, thiab lwm qhov yog txuas ncaj qha rau lub twj tso kua hluav taws hauv series.
② Parallel teeb tsa
Thaum ntau lub twj tua hluav taws txuas nrog rau qhov sib npaug, qhov sib txuas ntawm cov twj tua hluav taws yog hais txog cov khoom siv hluav taws xob ib txhij rau cov dej tua hluav taws los ntawm ob lossis ntau lub twj tua hluav taws. Lub luag haujlwm tseem ceeb ntawm kev sib txuas ntawm cov twj tua hluav taws yog txhawm rau nce tus nqi ntws, tab sis thaum cov nqi ntws tau nce siab, qhov system ntws yuav txo qis. Yog li ntawd, nws yog ib qho tsim nyog los xyuas qhov cuam tshuam ntawm kev ntws superposition ntawm qhov hluav taws xob siab ntawm cov twj tua hluav taws.
