1. Qhov zoo ntawm cov pawg prefabricated, pawg rods thiab lwm yam khoom los ntawm Shandong expressway guardrail mus rau qhov chaw tsim kho yuav tsum tau xyuas thiab txais nyob rau hauv nruj raws li cov qauv kev lees paub (xyuas cov ntaub ntawv ntawm prefabricated pawg, Hoobkas daim ntawv pov thawj, pawg foundation zoo soj ntsuam cov ntaub ntawv, lwm yam).
Kev tso cai ntau yam ntawm cov kab nrib pleb hauv pawg: qhov tob tob yog tsawg dua 5 hli, qhov ntev ntawm txhua qhov xau tsis ntau tshaj 100 hli, thiab qhov sib txuam tsis ntau tshaj 5% ntawm pawg ntev yuav tsum tau kho;qhov tob tob yog tsawg dua 10 hli, qhov ntev ntawm txhua qhov xau tsis ntau tshaj 300 hli, thiab tsis muaj ntau pawg ntev.Qhov sib txuam ntawm 10% ntawm qhov ntev, lossis qhov ntev ntawm lub puab tsaig tsis pub tshaj 100 hli, thiab cov kab nrib pleb tsis raug tso cai kho.kawg phaj dav hlau
2. Cov txheej txheem tuav ntawm pawg yuav tsum tau muab tso rau hauv txoj haujlwm uas tau teev tseg.
3. Lub chaw tsim kho yuav tsum tau soj ntsuam nruj me ntsis ua ntej rov xyuas dua.
Tom qab cov txheej txheem ntuj tsim, cov av nyob ib ncig ntawm pawg yuav raug compressed, thiab yog tias qhov kev ncua deb ntawm cov pawg tsawg dua li qhov ntau, cov pawg yuav offset los yog ntab cov pawg uas nyob ib sab.Txoj kev no tuaj yeem tshem tawm cov av extruded tshem tawm ntawm pawg thiab cov av extruded tshwm sim los ntawm cov av extruded mus rau ib qho twg, tab sis qhov kev tshem tawm ntawm pawg nruab nrab tsis tuaj yeem kov yeej, thiab siv tau los ntawm nruab nrab mus rau plaub kawg.Ob lub voj voog txoj kev piling (hauv qab no yog txoj hauv kev piling thiab pes tsawg pawg hauv pawg kev tsim kho).Txoj kev no siv ib pawg dhia thiab tso ntau sab pawg rau hauv lub voj voog thib ob li sai tau.Nws tuaj yeem tshem tawm feem ntau ntawm cov pawg sab hauv thiab txo cov av-squeezing nyhuv ntawm pawg.Qhov tsis zoo yog tias nws ua rau kom muaj kev hloov pauv ntawm pawg neeg tsav tsheb, uas tej zaum yuav yog vim tsis muaj cov txheej txheem tawg raws sij hawm, thiab cov neeg tsav tsheb pawg tsis tuaj yeem taug kev raws li tau npaj tseg, yog li txo cov haujlwm ua haujlwm.mus rau qhov txuas ntxiv.Yog li ntawd, kev xaiv ntawm kev tsim ua ntu zus, chav saib xyuas thiab chav tsim kho yuav tsum ua tib zoo xav txog ntau yam xws li qhov chaw, hom pawg, qhov xwm txheej thiab kev ua tiav ntawm qhov project, thiab lwm yam.
Hauv Shandong yoj guardrail manufacturers, nws yuav tsum tau ua raws li geometric linearity
Wave beam guardrails tsis yog tsim los txo qhov tshwm sim ntawm cov xwm txheej me.Lub guardrail tiv thaiv kev sib tsoo mechanism yog nqus cov kev sib tsoo lub zog ntawm lub tsheb, elastic-yas deformation ntawm lub tsheb lub cev, kev sib txhuam thiab txav ntawm lub tsheb lub cev los ntawm cov phaj guardrail, thiaj li tiv thaiv kev nyab xeeb ntawm cov neeg nyob.Lub yoj guardrail yog qhov sib txawv ntawm lwm yam kev nyab xeeb, nws yog los tiv thaiv kev puas tsuaj (deformation) ntawm lub rooj tsavxwm thiab lub tsheb nws tus kheej, tiv thaiv kev puas tsuaj loj dua.Teeb tsa lub rooj tiv thaiv kom tsis txhob muaj kev sib tsoo nrog lwm yam khoom txaus ntshai, thiab cov guardrails yuav tsum suav tias yog cov khoom txaus ntshai.Ntawd yog, yog tias, nyob rau hauv tib lub sijhawm, kev sib tsoo hnyav ntawm lub tsheb sib tsoo nrog qee yam khoom txaus ntshai qis dua li ntawm lub tsheb, lub guardrail yuav siv tsis tau los tiv thaiv cov khoom txaus ntshai.Piv txwv li, ntawm txoj kev tiaj tus, qis-cocoon txoj kev, qhov hnyav ntawm lub tsheb hla kev sib tsoo ntawm lub embankment yog tsawg dua li kev sib tsoo ntawm lub tsheb thiab tus neeg saib xyuas, txawm tias muaj ntau lub tsheb sib tsoo hauv qhov no, txoj kev. Kev tiv thaiv kev tiv thaiv, thiab lwm yam kev ntsuas kev nyab xeeb tsis tuaj yeem siv, piv txwv li, txoj kev geometry tau txhim kho, cov chaw taw qhia pom kev, teeb tsa kev txwv ceev, thiab kev tiv thaiv kev ua haujlwm ntawm txoj kev ntog tau zoo dua.
Tam sim no, ntau tus ncej barrier siv zinc steel guardrails, uas yog dav siv nyob rau hauv txoj kev loj thiab txoj kev loj guardrails.Galvanized guardrails account rau 69% ntawm tag nrho cov saum npoo-kho hlau.Vim qhov zoo corrosion kuj thiab cov khoom zoo nkauj ntawm cov ntawv galvanized, piv nrog rau lwm cov ntawv galvanized, nws cov nqi qis, thiab nws tau siv dav hauv kev tsim kho.
