Nyob rau hauv lub ntiaj teb no ntawm infrastructure thiab kev loj hlob hauv nroog, qhov tseem ceeb ntawm high-zoo manhole npog tsis tuaj yeem overstated.Cov khoom tseem ceeb no ua lub luag haujlwm tseem ceeb hauv kev ua kom muaj kev nyab xeeb thiab ua haujlwm ntawm txoj kev, kev taug kev, thiab kev siv hluav taws xob hauv av.Yog li ntawd, nws yog ib qho tseem ceeb rau kev nqis peev hauv manhole npog uas tsis yog tsuas yog ruaj khov thiab muaj zog, tab sis kuj ua tau raws li cov qauv kev lag luam siab tshaj plaws.Qhov ntawd yog qhov uas peb lub tuam txhab tuaj.
Peb lub tuam txhab yog ib tug ua lag luam ntawm cov kws tshaj lij, zoo ductile hlau manhole npog, tsim kom tau raws li EN124 cov qauv.Peb txaus siab los muab cov khoom lag luam uas tsis yog tsuas yog txhim khu kev qha thiab ruaj khov, tab sis kuj tseem pab txhim kho kev ua tau zoo thiab kev nyab xeeb ntawm nroog infrastructure.
Peb cov ductile hlau manhole npog yog tsim los ntawm cov ntaub ntawv zoo tshaj plaws, kom ntseeg tau tias lawv muaj lub zog tsim nyog thiab elasticity los tiv thaiv cov kev xav tau ntawm cov tsheb hnyav thiab hnyav ib puag ncig.Peb qhov kev cog lus rau kev siv cov khoom siv raw khoom zoo yog qhov ua pov thawj rau peb txoj kev cog lus rau kev xa cov khoom tsim los mus ntev.
Ib qho ntawm cov yam ntxwv tseem ceeb ntawm peb cov hlua hlau manhole npog yog lawv lub zog tshwj xeeb thiab ua haujlwm ntev.Cov npog no yog tsim los tiv thaiv qhov hnyav ntawm lub tsheb thiab cov tshuab hnyav yam tsis muaj kev cuam tshuam rau lawv txoj kev ncaj ncees.Qhov no ua kom lawv muab kev tiv thaiv mus ntev rau kev siv hluav taws xob hauv av thaum txo qis qhov xav tau kev saib xyuas thiab hloov pauv.
Ntxiv nrog rau lub zog, peb lub manhole npog yog tsim los ua haujlwm ntsiag to, tshem tawm cov suab nrov nrov uas feem ntau tsim los ntawm cov npog manhole.Qhov tshwj xeeb no tsis tsuas yog pab tsim kom muaj kev thaj yeeb nyab xeeb hauv nroog, tab sis kuj qhia peb txoj kev mob siab rau kev xa cov khoom lag luam tseem ceeb rau cov neeg siv kev paub thiab kev yooj yim.
Tsis tas li ntawd, peb cov ntaub npog manhole muaj cov yam ntxwv tiv thaiv tub sab, ua rau lawv muaj kev xaiv zoo rau thaj chaw ruaj ntseg.Cov npog no tau tsim thiab tsim los tiv thaiv kev nkag mus tsis tau thiab tiv thaiv kev ua tub sab nyiag thiab kev tsim txom thaum tiv thaiv kev nkag mus rau cov khoom siv tseem ceeb.
Lwm qhov tseem ceeb ntawm peb lub manhole npog yog lawv cov khoom tiv thaiv kev daws teeb meem.Cov npog no yog tsim los tiv thaiv kev nyob thiab txav mus los, ua kom lawv nyob ruaj ntseg hauv qhov chaw dhau sijhawm.Tsis tsuas yog qhov no txo qis kev pheej hmoo ntawm kev raug xwm txheej thiab kev puas tsuaj, nws tseem txo qhov kev xav tau ntawm kev hloov kho thiab kev saib xyuas, ua rau cov nqi txuag rau cov nroog thiab cov neeg ua haujlwm hauv vaj tse.
Hauv luv luv, peb lub tuam txhab tau cog lus los muab cov kws tshaj lij, cov khoom zoo tshaj plaws ntawm cov hlau manhole npog uas ua tau raws li thiab tshaj EN124 cov qauv.Kev tsom mus rau kev siv cov khoom siv raw khoom zoo, peb cov khoom muaj lub zog zoo dua, ua haujlwm ntev thiab ntau yam ntawm cov yam ntxwv uas pab txhim kho tag nrho kev nyab xeeb thiab kev ua haujlwm ntawm nroog infrastructure.Los ntawm kev xaiv peb cov manhole npog, cov neeg siv khoom tuaj yeem xav tias muaj kev ntseeg siab hauv lawv cov peev hauv kev txhim khu kev qha, kev daws teeb meem ntev uas ua haujlwm tseem ceeb thiab cov neeg siv kev txaus siab.
