Ductile hlau manhole npog yog siv dav hauv kev tsim kho hauv nroog niaj hnub thiab kev lag luam vim lawv qhov kev ua tau zoo heev.
Cov hauv qab no txheeb xyuas lawv cov ntawv thov tseem ceeb ntawm ntau qhov ntev:
Kev faib tawm los ntawm Txoj Kev Hom thiab Kev Ua Haujlwm Scenarios
Txoj Kev Hauv Nroog Loj thiab Siab - Txoj Kev Tsheb:Ductile hlau manhole npog, nrog lawv lub zog siab (lub zog tensile Ntau dua lossis sib npaug ntawm 420MPa) thiab siab tawv (qhov cuam tshuam tus nqi ntau dua 10 npaug ntawm grey cam khwb cia hlau), tuaj yeem tiv taus kev sib tsoo los ntawm cov tsheb hnyav, tiv thaiv kev deformation lossis tawg. Lawv yog thawj qhov kev xaiv rau hnyav- chaw thau khoom xws li hauv nroog txoj kev loj thiab txoj kev loj nkag / tawm.
Sidewalks thiab Public Squares:Lawv zoo corrosion kuj (corrosion npaum li cas nyob rau hauv 90 hnub nyob rau hauv dej tshuaj tsuag corrosion yog tsuas yog 1/40 ntawm cov yeeb nkab steel) thiab ntev kev pab cuam lub neej (5 npaug ntawm zoo tib yam steel kav) cia lawv nyob ruaj khov txawm nyob rau hauv ib puag ncig ntub thiab los nag. Nyob rau tib lub sijhawm, qhov saum npoo feem ntau muaj kev tiv thaiv -slip tsim los txhim kho kev nyab xeeb ntawm cov neeg taug kev, ua rau lawv tsim nyog rau thaj chaw muaj neeg coob xws li chaw lag luam, chaw ua si, thiab chaw nres tsheb. Txoj kev nyob deb nroog thiab cable manholes: Hauv txoj kev nyob deb nroog nrog cov tsheb thauj mus los tsis zoo lossis hauv lub zog thiab kev sib txuas lus cable manholes, square ductile hlau manhole npog feem ntau siv. Lawv tsim tau zoo dua los tiv thaiv cov dej nag thiab cov khib nyiab los ntawm kev nkag mus rau hauv lub manhole, yog li ua tau raws li qhov yuav tsum tau ua.
Kev faib tawm los ntawm Manhole Cover Structure Design
Standard Round Manhole npog:Siv dav hauv kev tswj hwm hauv nroog, feem ntau vim lawv cov yam ntxwv geometric - puag ncig manhole npog yuav tsis poob rau hauv lub manhole tsis hais txog kev sib hloov, ua kom muaj kev nyab xeeb siab thiab sawv cev rau tus qauv tsim.
Wide-Edge Anti-Txoj Cai Manhole Npog:Hais txog qhov teeb meem ntawm cov tsoos manhole npog yooj yim daws teeb meem, cov npog no muaj qhov dav dav tsim, ua rau thaj chaw txhawb nqa thiab dispersing siab. Lawv tshwj xeeb tshaj yog tsim rau cov kev tsim tshiab tshiab, cov hauv paus hauv av, los yog cov cheeb tsam uas muaj kev sib haum xeeb tsis sib xws, ua kom txoj kev du du thiab kev nplij siab.
Kev faib tawm los ntawm Environmental thiab Durability Requirements
Corrosive Environments:Hauv thaj chaw ntug dej hiav txwv, thaj chaw muaj tshuaj lom neeg, lossis txoj kev caij ntuj no siv de- cov kab mob icing, cov hlau nplaum zoo dua corrosion thiab oxidation kuj zoo dua rau cov cam khwb cia hlau thiab cov hlau cam khwb cia, ua kom ntev -lub sij hawm tiv thaiv ntsev tsuag, kua qaub los nag, thiab lwm yam corrosive agents.
Huab cua kub ib puag ncig:Nws zoo heev thaum tshav kub kub thiab txias tsis kam ua rau nws haum rau siab -kub qhov cub pipeline qhov dej los yog cov chaw hauv nroog hauv cheeb tsam txias heev, tsis tshua muaj kev tawg vim qhov kub thiab txias hloov tam sim ntawd.
Classification los ntawm Economy thiab Substitutability
Tus nqi - Cov Haujlwm Tseem Ceeb:Cov hlau tsis tshua kim dua li cov hlau cam khwb cia, tsis tau muaj zog sib piv. Nws cov high-casting efficiency thiab tsawg machining cov nqi ua rau nws yog ib qho zoo tagnrho lwm txoj rau kim cam khwb cia hlau qhov chaw, dav siv nyob rau hauv lub nroog tej yaam num nrog tsawg nyiaj txiag tab sis muaj kev ntseeg siab yuav tsum tau.
Kev xav tau ntawm lub teeb:Muab piv rau qhov zoo li grey cam khwb cia hlau manhole npog, ductile hlau manhole npog yog kwv yees li 30% sib dua, yooj yim rau kev thauj mus los, kev teeb tsa, thiab kev saib xyuas, txo cov nqi zog, thiab ua rau lawv tsim nyog rau kev kuaj xyuas qhov dej uas yuav tsum tau qhib ntau zaus lossis hauv thaj chaw deb.
Nyob rau hauv cov ntsiab lus, ductile hlau manhole npog, nrog lawv cov txiaj ntsig zoo ntawm lub zog siab, siab tawv, corrosion kuj, lub neej ntev, thiab kev lag luam, tau hloov zuj zus los ntawm "cov npog" rau hauv cov khoom tseem ceeb kom ntseeg tau tias muaj kev nyab xeeb thiab ruaj khov hauv nroog infrastructure, nrog rau cov ntawv thov npog ntau yam kev xav tau los ntawm cov chaw hauv nroog mus rau cov chaw nyob deb nroog, los ntawm cov tsheb thauj mus los tshwj xeeb.
