Hauv kev ua haujlwm hauv nroog, kev ua yeeb yam ntawm cov raj xa hluav taws xob tsis ncaj ncees, dej ib puag ncig kev tswj dej nyab xeeb, thiab ntev} kev ua haujlwm thiab tu cov nqi. Kev siv cov kav dej sib txawv, ib zaug vim lawv lub zog siab thiab tus nqi qis, tau muaj kev sib tw tsis zoo, cov pob qij txha tsis muaj zog, thiab kev tsim kho tsawg. Nrog kev sib tsoo hauv cov khoom siv science thiab siv thev naus laus zis, cov raj hluav taws xob hloov chaw ntawm Imme tau kho dua tshiab, thiab lub neej qis- lub voj voog.Yog tiasHoobkas 30+} xyoo tsim cov khoom txhawb cov xim / qhov loj me customized kev txhawb nqaCov Qauv Dawb.Welnets los sab laj rau cov catalog thiab kuaj dawb.Qhov no yog peb lub vev xaib Facebook:www.facebook.com.
I. Peb txoj kev sib tw tseem ceeb ntawm cov kav hlau ua khoom
1. Tsis txaus los tiv thaiv {{1} saib thiab corrosion Kuj: cov kev sib tw ntawm cov nyom ntawm cov av hauv av thiab kav dej
Pob zeb ua cov kav hlau txais kev sib txuas cov hau kev sib txuas, cia siab rau ntawm cov pob zeb sib khi lossis roj carkeets rau kev ua haujlwm waterproofing. Txawm li cas los xij, yam xws li cov av sib hais haum thiab cov teeb meem kev tsim kho no feem ntau ua rau kev to taub dej ntawm 15% -20%. Cov ntaub ntawv los ntawm kev kuaj xyuas cov khoom noj hauv ib lub nroog uas pom tias cov kav dej ua kom ntev dua txog li 3.2 kev pheej hmoo tsib xyoos ntau ntxiv, kev pheej hmoo ua haujlwm, kev pheej hmoo pheej hmoo ntau txog kev pheej hmoo ntawm cov av. Tsis tas li ntawd, cov kav hlau ua kom tsis muaj zog tiv thaiv kom tsis muaj cov cav dej khov kho thiab muaj kev lag luam sab hauv los ntawm 20% -30% thiab cuam tshuam ncaj qha rau kev nqus dej.
2. Cov kev tsim kho tsawg: Lub voj voog ua phem ntawm cov khoom siv hnyav ntawm cov khoom siv hnyav thiab ua haujlwm qeeb
Cov kav hlau ua kom hnyav tuaj yeem hnyav txog 1.2 tons ib chav (rau DN800 cov lus qhia hnyav heev xws li cranes thiab teeb tsa ntev ntev thiab huab cua muaj kev txwv. Piv txwv li, ib 48 - kilitus lim dej network siv cov kuab-pob zeb kaw, ua rau cov kev tsis txaus siab thiab nyob hauv kev tsis txaus siab.
3. Lub neej siab {{- tus nqi: tus nqi zais zais ntawm kev saib xyuas nquag thiab cov khoom pov tseg
Txawm hais tias cov kav dej ua ke tau thov kom muaj 50 xyoo lub neej, lawv lub voj voog hloov chaw tiag yog feem ntau luv rau 15-20 xyoo vim yog cov teeb meem thiab xau dej. Kev tshawb fawb ib rooj plaub ntawm kev kho kom huv ntawm kev ua haujlwm ntawm kev ua haujlwm thiab kev txij nkawm rau cov khoom lag luam uas tsis sib xws thiab sim ua kom lub sim.
Ii. Cov kev sib tsoo txheej thiab cov kev daws teeb meem ntawm ifan lub nplhaib pob tw hdpe pipes HDPE
1. Tshuaj lom neeg Kuj: los ntawm "passive tiv thaiv" rau "nquag tiv thaiv"
Lub tsev molecular ruaj molecular ntawm cov khoom siv HDPE muab tej yam rau cov xov xwm dolosive, zam rau pH theem kev tawm tsam, zam rau pH theem li sulfates thiab chloride ions. Nyob rau hauv ib lub irrigation qhov project ntawm ib qos cog cov qos yaj ywm cog paus hauv dingxi, gansu, ifan hansu pipes hloov chaw quav yeeb quav me hlau rau benzene thiab toluene. Tom qab ob xyoos ntawm kev ua haujlwm, sab hauv phab ntsa pom tias tsis muaj xeb, ua rau pom cov tshuaj zoo tshaj piv rau cov ntaub ntawv ib txwm muaj.
2. Lub nplhaib High Stiffans Tsim: "Rigidity Revolution" rau cov kav dej yooj ywm
Ifan tau ua tiav qhov nyiaj tshuav ntawm kev hloov pauv thiab nruj los ntawm cov qauv kev tsim kho tshiab:
Ob Chav -} phab ntsa coiled ntxiv cov tswv yim: Phab ntsa du sau txo cov av hauv av sab nraud, ua tiav lub nplhaib sib sib zog nqus ntawm 8 K'} me nyuam} me nyuam} me nyuam} me nyuam} me nyuam.
Hluav Taws Xob Vuam Tshuab: Koom nrog txoj kev sib koom tes ntau ntawm cov yeeb nkab lub cev, ua kom muaj xoom kov. Nyob rau hauv ib txoj haujlwm muaj cua daj cua dub ntws tawm hauv Shanghai, 48.4 mais Tom qab peb xyoos kev ua haujlwm, tus nqi dej xau poob ntawm 15% mus rau 2%, thiab cov khoom siv pov tseg kom tau nce rau 95%.
{{03. 40% txhim kho hauv kev tsim kho tau: syergy ntawm lub teeb thiab modular installation
Phaus zoo dua: Ifan Hdpe kav hlau hnyav tsuas yog ib qho -}}
Hloov cov qauv kev sib txuas: Kub -} kub taub hau vuam lub sijhawm rau 10 feeb, txhim kho cov kav hlau ua haujlwm los ntawm 60% piv rau cov kav hlau ua pob zeb.
Sib cav nrog cov thev naus laus zis trenchless: Yog tias cov kav dej HDPE tuaj yeem ua ke nrog kab rov tav dhuav thiab cov yeeb nkab jacking cov txheej txheem, zam kev khawb. Hauv cov tshuaj lag luam chaw ua si hauv Lianyungang, Ifan HDPE cov kav dej hloov pauv, txo lub sijhawm tsim kho ntawm 45 hnub thiab txiav cov nqi los ntawm 30%.
III. Lub neej {{1- Lub voj voog tus nqi sib piv: los ntawm "luv {2} {ntev}} lub peev txheej"
Rau 10-kilometer dn800 Ua Kua Hlau Network, ib tus nqi sib piv
Thawj zaug kev nqis peev: Txawm tias HDPE kav dej muaj nyiaj 15% ntau dua ib chav nqi, lawv cov nqi nruab nrab yog 20% qis dua vim muaj cov cuab yeej siv hnyav thiab kev kho mob sib koom ua ke.
Kev ua haujlwm thiab txij nkawm cov nqi: Kev Txij Nkawm - dawb Xwm ntawm hdpe pipes txo 20}}} xyoo o & m cov nuj nqis rau ib feem ntawm cov uas rau cov kav hlau ua pob.
Ib puag ncig tus nqi: Kev xau los ntawm cov kav hlau ua kom muaj kuab phom
IV. Yav Tom Ntej: Qhov "Dual Drive" ntawm kev txawj ntse thiab muaj kev ruaj khov
Ifan tau tshaj tawm cov tswv yim HDPE ua ke, muaj peev xwm ntawm cov ntaubntawv ceev ceev thaum lub sij hawm vuam thiab saib xyuas kev txaus siab, thiab lwm yam kev ntsuas ntawm sensors. Nyob rau hauv lub chaw tswj dej ntse, cov kav dej ua tiav qhov chaw xau qhov chaw yog qhov tseeb ntawm ± 0.5 metres, txo cov lus teb los ntawm plaub teev mus rau 30 feeb. Ib qho ntxiv, cov kav dej ntsuab ua los ntawm kev rov ua HDPE resin txo cov pa roj carbon}} ntawm} ntawm} ntawm cov hom phiaj ntawm carbon ncov thiab newsrality.

Los ntawm kev pab raws li lub "thauj tog rau nkoj" thaum Shanghai cov dej nag ntau heev cuam tshuam nrog cov khoom tseem ceeb ntawm cov kav dej sib txawv ntawm cov kav dej sib txawv, lub zog, thiab siv lub neej ntev. Lawv cov kev tshaj tawm kev tsim kho tsis yog tsuas yog them cov qauv kev txwv rau hauv cov chaw dej nyab loj, txhim kho kev tswj hwm dej hauv nroog, thiab txhawb nqa cov dej ntws deb. Nrog rau kev sib koom ua ke ntawm cov ntse thiab cov nyom ntsuab yog cov phiaj xwm tseem ceeb rau cov phiaj xwm yav tom ntej, kev tsav tsheb rau kev lag luam zoo dua thiab muaj kev ruaj khov.
