Manhole npog,Raws li cov khoom tseem ceeb ntawm cov kav dej hauv nroog hauv nroog, ris lub luag haujlwm rau kev nyab xeeb hauv nroog, ecology, thiab kev tswj hwm. Nrog rau kev hloov pauv hauv nroog mus rau kev ua kom zoo dua qub, kev txawj ntse, thiab kev cog qoob loo, kev txawj ntse, kev tiv thaiv ib puag ncig, thiab kev nyab xeeb tau dhau los ua qhov tseem ceeb ntawm kev hloov pauv hauv kev lag luam, tsav tsheb manhole npog kom dhia los ntawm cov khoom siv tseem ceeb mus rau cov kev pabcuam dav dav.
I. Intelligent Upgrade: Los ntawm Kev Tswj Tus Kheej mus rau Kev Tiv Thaiv Proactive
Ib txwm manhole npog raug kev txom nyem los ntawm kev ua haujlwm qis thiab qeeb teb rau cov kev phom sij zais vim yog kev tshuaj xyuas phau ntawv. Kev txawj ntse hloov kho dua tshiab, los ntawm Is Taws Nem ntawm Yam thiab cov thev naus laus zis sensor, ua tiav kev hloov pauv ntawm kev tswj hwm mus rau kev tiv thaiv kev tiv thaiv. Tam sim no, ntse manhole npog tau dav siv. Piv txwv li, tus neeg tsav dav hlau npog ntawm txoj kev Yangqiao hauv Fuzhou tuaj yeem saib xyuas qhov tsis sib xws ntawm lub sijhawm tiag tiag thiab muab qhov thib ob - theem ceeb toom ntxov [4]. Lawv kev koom ua ke nrog cov nroog ntse ua tiav "ib lub npog, siv ntau yam," thiab los ntawm qhov kawg ntawm 2023, tus naj npawb ntawm cov ntsia hlau npog thoob tebchaws tau tshaj 850,000 teeb tsa, tsim kom muaj kev tswj hwm kev txawj ntse yav tom ntej.
II. Kev Txhim Kho Ib puag ncig: Los ntawm kev siv siab thiab muaj kuab paug siab rau ntsuab thiab qis-Carbon
Ib txwm cam khwb cia hlau thiab pob zeb manhole npog yog siab -siv thiab siab - pa phem. Raws li "dual carbon" lub hom phiaj, kev hloov kho ib puag ncig tsom mus rau cov khoom siv tshiab thiab kev rov ua dua tshiab. Cov ntaub ntawv tshiab ib puag ncig zoo xws li fiberglass yog maj mam hloov cov ntaub ntawv tsoos. Recycled ductile hlau account rau 22% ntawm tag nrho, thiab cov pa roj carbon hneev taw ntawm kev tsim cov khib nyiab tag nrho cov manhole npog tau raug txo los ntawm 35%. Cov txheej txheem tsis siv neeg txo cov pa phem, thiab ib puag ncig tus phooj ywg manhole npog tuaj yeem pab tsim cov sponge nroog. Nyob rau hauv lub neej yav tom ntej, ib tug ntsuab industrial saw nrog ib tug tag nrho lub neej voj voog yuav tsim.
III. Kev Txhim Kho Kev Nyab Xeeb: Los ntawm Kev Tiv Thaiv Yooj Yim rau Tag Nrho -Scenario Guarantee
Hauv kev teb rau cov kev phom sij zais ntawm tub sab nyiag thiab qhov tsis muaj zog ntawm cov tsoos manhole npog, kev txhim kho kev nyab xeeb tau tsim muaj ntau qhov kev tiv thaiv ntau yam. Fiberglass manhole npog muaj qhov cuam tshuam zoo tiv thaiv thiab ua kom tsis muaj zog, thiab muaj kev tsim kho kom zoo rau cov xwm txheej sib txawv. Tus qauv tshiab hauv lub tebchaws ntxiv dag zog rau qhov yuav tsum tau muaj rau kev tiv thaiv - tub sab nyiag thiab tiv thaiv - kev daws teeb meem, thiab kev ua lag luam sampling pass tus nqi nce mus txog 94.7%. Ntau thaj chaw tau tsim "ib daim npog, ib daim ntawv" los siv lub luag haujlwm, thiab qhov xwm txheej-raws li kev daws teeb meem tau txhim kho kev ruaj ntseg ntxiv.
IV. Kev Lag Luam Summary thiab Yav Tom Ntej Outlook
Kev txawj ntse, ib puag ncig tus phooj ywg, thiab kev nyab xeeb thev naus laus zis tau txhawb nqa hauv kev sib koom ua ke, ua rau kev lag luam hloov pauv los ntawm kev tsim khoom loj mus rau hauv nruab nrab thiab tsim qauv [3]. Nyob rau hauv lub neej yav tom ntej, nrog rau kev nrawm ntawm kev rov ua dua tshiab hauv nroog, lub davhlau ya nyob twg ntse yuav ua tiav tag nrho kev nkag siab thiab kev sib txuas, qhov feem ntawm cov khoom siv rov ua dua tshiab hauv thaj chaw tiv thaiv ib puag ncig yuav ncav cuag ntau dua 35%, thiab cov qauv kev nyab xeeb ntawm lub davhlau ya nyob twg yuav txuas ntxiv mus ntxiv [3]. Kev lag luam yuav tsum tau tsom mus rau kev tsim kho thev naus laus zis los pab cov nroog kom ua tiav qib siab - kev txhim kho zoo.
