Kev xaiv cov khoom txiav txim siab Manhole npog Lifespan
Manhole npog zoo li cov nyees khawm ntawm lub nroog; xaiv cov khoom tsis raug tuaj yeem ua rau muaj qhov tshwm sim loj. Ntawm cov khoom siv, cov hlau nplaum muaj zog compressive zoo heev thiab tsim nyog rau thaj chaw uas muaj tsheb loj; Cov ntaub ntawv sib xyaw yog lub teeb yuag thiab haum rau kev taug kev; thiab steel fiber reinforced qhob sib npaug kev lag luam thiab thauj khoom -cov kev cai. Qhov tseem ceeb yog xav txog qhov kev siv scenario: cov cheeb tsam uas muaj tsheb thauj mus los hnyav yuav tsum muaj cov khoom siv uas tuaj yeem tiv taus ntau dua 30 tons, thaum thaj chaw nyob tsuas yog xav tau 15-tuj peev txheej.
Anti-Fall Design muaj nws txoj kev dag
Tiv thaiv kev ntog tsis yog ib qho teeb meem ntawm kev ntxiv ib lub hau npog:
- Muab ob npaug rau- txheej txheej: Ib qho kev thauj khoom sab saud- txheej txheej kabmob + qis dua los tiv thaiv- qhov poob qis, tiv thaiv kev tsim ntawm lub qhov txawm tias lub hau npog puas lawm.
- Cov cuab yeej ntsuas phoo: Tiv thaiv kev ua tub sab nyiag thiab tshem tawm, txo qhov kev pheej hmoo ntawm tib neeg -kev puas tsuaj.
- Optimized kua: tsim tshwj xeeb lub qhov ua kom cov kua dej du thiab tiv thaiv cov dej tsub zuj zuj thiab corrosion.
- Cov cim ceeb toom: cov kab teeb ci ntsa iab lossis cov qauv tsa tau ceeb toom cov neeg taug kev kom ceev faj.
Kev saib xyuas niaj hnub feem ntau tsis saib xyuas
90% ntawm manhole npog xwm txheej tshwm sim los ntawm kev saib xyuas tsis saib xyuas:
- Tshawb xyuas lub hau kom xoob lossis tshem tawm txhua hli.
- Ntxuav cov qhov dej ua ntej thiab tom qab lub caij ntuj nag los tiv thaiv kev thaiv.
- Hloov npog tam sim ntawd thaum pom cov kab nrib pleb; Cov kab nrib pleb me me tuaj yeem nthuav dav sai.
- Yog hais tias ib puag ncig ntawm txoj kev ntog los ntawm ntau tshaj 2 centimeters, yuav tsum muaj kev tshuaj xyuas zoo.
- De-icing ntsev nyob rau hauv lub caij ntuj no accelerates corrosion thiab yuav tsum tau tshwj xeeb kev tiv thaiv.
