Nrog rau kev nce qib ntawm kev sib koom ua ke hauv nroog thiab cov dej hauv nroog, daws cov teeb meem ntawm kev ncua ntev -kev deb thiab hla- cov dej xa mus hauv cheeb tsam thiab ua kom muaj kev ruaj ntseg, kev nyab xeeb, thiab kev lag luam ntawm cov dej tau dhau los ua qhov tseem ceeb rau kev txuag dej thiab cov dej num hauv nroog. Ntawm cov khoom siv sib txuas ntawm cov kav dej, cov kav dej hlau, nrog rau lawv cov yam ntxwv ua tau zoo, tau dhau los ua cov khoom siv rau kev sib kis dej mus ntev, tsim kom muaj "lifeline" rau kev sib koom ua ke hauv nroog thiab cov dej nyob deb nroog thiab muab kev txhawb nqa tseem ceeb rau kev txo nqi, kev txhim kho kev ua haujlwm, thiab ntev - lub sijhawm ua haujlwm ntawm ntau yam dej num.
Kev ntseeg tau lav los ntawm "qhov chaw" mus rau "kev lag luam ua lag luam"
Cov kav hlau kav hlau tau raug qhuas tias muaj "qhov tseem ceeb ntawm cov hlau thiab kev ua haujlwm ntawm cov hlau." Lawv microstructure tau txais kev kho mob spheroidization, hloov cov flake graphite hauv cov tsoos grey cam khwb cia hlau rau hauv cov duab kheej kheej. Qhov no ua rau cov khoom siv lub zog tensile ntau dua 420 MPa thaum tuav lub elongation ntawm tsis pub tsawg tshaj 10%. Qhov kev sib xyaw ua ke ntawm kev nruj thiab kev hloov pauv no ua rau lawv muaj kev hloov pauv tshwj xeeb thaum raug rau cov dej sab hauv thiab cov khoom siv sab nraud- tiv thaiv dej rauj cuam tshuam thaum nqus cov kev hloov pauv los ntawm lub hauv paus kev daws teeb meem los ntawm cov pob qij txha hloov tau.
Rau kev sib koom ua ke hauv nroog thiab nyob deb nroog cov dej num, cov kav dej feem ntau hla cov chaw sib txawv ntawm thaj chaw, los ntawm thaj av mus rau toj, los ntawm thaj av mus rau cov zos, nrog rau cov xwm txheej nyuaj thiab ntau yam geological. Cov pob qij txha hloov tau yooj yim ntawm cov kav dej hlau tso cai rau qee qhov kev cuam tshuam ntawm angular deflection, ua kom pom kev hloov pauv zoo rau av qeeg, kev sib haum xeeb hauv paus, thiab kev hloov pauv ntawm cov khoom siv sab nraud, txhim kho kev nyab xeeb ntawm cov dej xa mus.
Kev tawg hauv ultra- txoj kab uas hla loj thev naus laus zis: Kev xa dej muaj peev xwm nce mus txog qib tshiab
Qhov zoo ntawm cov kav hlau kav dej tau pom zoo nyob rau hauv Zhangzhou Jiulongjiang Water Diversion Project, qhov project tseem ceeb hauv tebchaws. Qhov project no, nrog rau tag nrho cov peev ntawm 5.112 billion yuan thiab tag nrho ntev ntawm ze li ntawm 125 kilometers, ua tiav lub ntiaj teb thawj DN2800 ultra- txoj kab uas hla loj ductile hlau yeeb nkab.
Nrog ze li ntawm 20-fold nce hauv dej thauj khoom muaj peev xwm-DN2800 pipeline muaj txoj kab uas hla 1.8 meters loj dua li DN1000 cov kav dej uas nquag siv, tab sis nws lub peev xwm xa dej tau nce ntxiv, ua tau raws li qhov xav tau ntawm qhov ntev - nrug, siab - ntws dej. Thaum lub sij hawm kev xaiv cov txheej txheem, lub tsev tsim tau taw qhia tias lub ultra- txoj kab uas hla loj ductile hlau yeeb nkab muaj corrosion kuj zoo heev, zoo sib koom tes sealing, siv sij hawm luv luv, thiab tsis tshua muaj kev tsim kho thiab tu nqi, ncaj qha hais txog kev lag luam mob cov ntsiab lus ntawm ib txwm loj-inch dej conveyance tej yaam num, xws li ntev cycles, siab poob siab, thiab kim kho.
Kev txhim kho kev ua haujlwm tau zoo dua qub - cov kav hlau kav hlau siv cov qhov (socket) txuas, tshem tawm qhov xav tau ntawm - qhov chaw vuam thiab theem nrab los tiv thaiv - kev kho corrosion, uas ua rau muaj kev txhim kho siab heev.
Kev tiv thaiv corrosion thiab kev ruaj ntseg dej: lub hauv paus rau 50-xyoo lifespan
Ntev - cov kav dej nyob deb feem ntau hla ntau qhov chaw ib puag ncig, xws li cov av acidic mus rau cov dej qab ntsev heev - thaj chaw alkali, muaj ntau yam kev pheej hmoo ntawm corrosion. Cov kav dej hlau ua kom muaj kev tiv thaiv muaj zog los ntawm ntau- txheej tiv thaiv- txheej txheem corrosion: cov phab ntsa sab nrauv yog coated nrog zinc txheej (tsis pub tsawg tshaj 200g / m²) + asphalt xim, thaum lub phab ntsa sab hauv yog lined nrog cement mortar, ua ib qho kev tiv thaiv ntawm lub cev thiab kev tiv thaiv hluav taws xob.
Los ntawm kev txhawb nqa cov haujlwm ntawm Sab Qab Teb - mus rau -North Water Diversion Project mus rau Jiulong River Water Diversion Project, los ntawm kev kho dej hauv nroog thiab cov neeg nyob deb nroog mus rau kev lag luam dej xa mus rau cov kav dej, cov kav dej hlau tau sau ib tshooj tseem ceeb hauv kuv lub teb chaws txoj kev txuag dej.
Raws li cov kws tshaj lij kev tsim khoom tshwj xeeb hauv cov kav hlau kav hlau, peb muab cov kev pabcuam dav dav rau peb cov neeg siv khoom, los ntawm kev xaiv cov yeeb nkab thiab kev tsim vaj tsev rau kev tsim kho. Txawm hais tias koj tab tom npaj ib qhov ntev - txoj haujlwm xa dej nyob deb lossis ntsib kev hloov kho cov kav dej, peb zoo siab tos txais koj cov lus nug thiab kev sib tham!
