Guardrail Height Specifications rau Sidewalks thiab Cov xwm txheej tshwj xeeb
Sab nrauv guardrails: Qhov siab ntawm tus choj guardrails nyob rau sab nrauv ntawm txoj kev taug kev los yog txoj siv sia yuav tsum tsis pub tsawg tshaj 1.10 meters. Qhov siab tshaj plaws qhov sib nrug ntawm cov khoom tiv thaiv yuav tsum tsis pub tshaj 140 hli, thiab kab rov tav bar guardrails tsis pom zoo.
Guardrails hla cov kev tsheb tseem ceeb: Thaum cov choj hla txoj kev tseem ceeb xws li kev nthuav dav, kev tsheb ciav hlau hauv nroog, txoj kev loj, thiab cov kab tsheb ciav hlau, cov kab thaiv kev tiv thaiv yuav tsum tau ntxiv rau txoj kev taug kev guardrails ntawm tus choj lawj. Qhov siab ntawm lub netting yuav tsum tsis pub tsawg tshaj 2 meters, thiab qhov ntev ntawm lub netting yuav tsum zoo dua yog qhov dav ntawm lub underpass thiab ncua mus txog 10 meters tawm ntawm txoj kev ntawm txhua sab.
Kev tsim thiab kev tsim kho kev txiav txim siab
1. Kev Tiv Thaiv Qib Xaiv: Cov qib kev tiv thaiv ntawm cov choj railings yuav tsum tau txiav txim siab raws li cov xwm txheej xws li kev khiav tsheb khiav, hom tsheb, thiab kev tsim ceev.
2. Kev sib txuam nrog kev nthuav dav: Kev sib txuam tsim ntawm railings nrog expansion pob qij txha thiab lwm qhov chaw ntxiv yuav tsum ua raws li cov kev cai ntawm "Tsim Specifications for Highway Traffic Safety Facilities".
3. Toj roob hauv pes Harmony: Cov duab thiab xim ntawm cov choj railings yuav tsum sib haum xeeb nrog ib puag ncig ib puag ncig. Kev tsim toj roob hauv pes yog pom zoo rau cov choj tseem ceeb.
4. Kev Tswj Xyuas Kev Ua Haujlwm Zoo: Thaum lub sijhawm tsim kho, kev txhim kho qhov tseeb ntawm cov railings yuav tsum tau ua kom ntseeg tau, tshwj xeeb tshaj yog qhov verticality ntawm cov ncej thiab kab rov tav ntawm kab teeb, kom lav tag nrho kev ruaj ntseg thiab kev tiv thaiv kev ua haujlwm ntawm cov railings.
Hauv cov ntsiab lus, qhov siab specifications rau choj railings yog tsim raws li qib kev tiv thaiv, kev siv ib puag ncig, thiab kev tsim qauv. Lawv lub hom phiaj yog ua kom tau raws li kev tiv thaiv kev nyab xeeb thaum tseem xav txog kev lag luam thiab kev zoo nkauj. Raws li ib tug neeg muag khoom, koj yuav tsum nruj me ntsis ua raws li lub teb chaws cov qauv hauv cov khoom tsim thiab kev tsim khoom los xyuas kom meej tias tus choj railings koj muab tau raws li qhov xav tau kev nyab xeeb ntawm cov xwm txheej sib txawv.
