Izinsimbi zokuqapha emgwaqeni zivame ukuhlukaniswa zibe yizinsimbi zokuqapha eziguquguqukayo, izinsimbi eziqinile eziqinile neziqinile. Ama-guardrails aguquguqukayo ngokuvamile abhekisela kuma- guardrail amakhebula, ama- guardrails aqinile ngokuvamile abhekisela kuma- guardrail osimende kasimende, kanti ama- guardrails aqinile ngokuvamile abhekisela kuma- guardrails. I-Beam fence guardrail iyisakhiwo sohlaka esihlanganiswe nezinsika, sincike ekuguquguqukeni nasekuqineni kwe-Guardrail ukuze imelane nokushayisana kwezimoto. I-Beam guardrails inokuqina nokuqina okuthile, futhi imunca amandla okushayisana ngokuguqulwa kwe-crossbeam. Izingxenye zayo ezilimele kulula ukuzishintsha, zibe nomthelela othile wokungeniswa okubukwayo, zingahlanganiswa nokuma komugqa womgwaqo, futhi zibe nokubukeka okuhle. Phakathi kwazo, uthayela wokulinda uthayela usetshenziswa kabanzi ekhaya naphesheya eminyakeni yamuva. Okwebanga elibanzi.
1. Izimiso zokubeka izinsimbi zokuqapha eceleni komgwaqo
Izinsimbi zokuqapha eziseceleni komgwaqo zihlukaniswe ngokuyinhloko zibe izinhlobo ezimbili: imisila yokuvikela kanye nezinsimbi zokuvikela izithiyo. Ubude obuncane bokumisa eceleni komgwaqo ngamamitha angama-70. Uma ibanga eliphakathi kwezingxenye ezimbili zama- guardrails lingaphansi kwamamitha angu-100, kuhle ukuthi uwasethe ngokuqhubekayo phakathi kwezigaba ezimbili. I-Guardrail yocingo ihlanganiswe phakathi kwezingxenye ezimbili zokugcwalisa. Ingxenye yokumba enobude obungaphansi kwamamitha ayi-100 kufanele iqhubeke nemivimbo yezingxenye zokugcwalisa kuzo zombili iziphetho. Ekuklanyweni kwezinsimbi zokuqapha eziseceleni komgwaqo, izinsimbi zokuqapha kufanele zisethwe uma kuhlangatshezwana nanoma yimiphi yale mibandela:
A. Izigaba lapho i-slope yomgwaqo i-i kanye nobude bodonga h kungaphakathi kwebanga elinomthunzi loMfanekiso 1.
B. Izigaba eziphambana nomzila wesitimela nothelawayeka, lapho izimoto zineZigaba lapho imoto ingase iwele kumzila wesitimela ophambanayo noma eminye imigwaqo.
C. Izigaba lapho kunemifula, amachibi, izilwandle, amaxhaphozi namanye amanzi phakathi kwamamitha angu-1.0 ukusuka phansi kombhede wemigwaqo emigwaqweni yezimoto ezihamba phambili noma ezimotweni, nalapho izimoto zingaba yingozi kakhulu uma ziwela kuzo.
D. Indawo engunxantathu yendlela yokungena nephumayo yophambano lwezindlela ezihamba phambili kanye nangaphandle kwamajika erediyasi amancane erempu.
2. Izinsimbi zokuqapha umgwaqo kufanele zifakwe kunoma yiziphi izimo ezilandelayo:
A. Izigaba lapho i-slope yomgwaqo i-i kanye nobude bodonga h kungaphezu komugqa wamachashazi kuMfanekiso 1.
B. Izigaba lapho umthambeka u-i kanye nobude bodonga h kungaphakathi kwamamitha angu-1.0 ukusuka emaphethelweni ehlombe lomhlaba emigwaqweni ehamba phambili noma emigwaqweni yezinga lokuqala yezimoto i-Shanghai epoxy floor, lapho kunezakhiwo ezifana nezakhiwo ze-gantry, izingcingo eziphuthumayo, izinsika noma ama-abutments of overpasses.
C. Ukuhambisana nomzila wesitimela nemigwaqo emikhulu, lapho izimoto zingagqekeza kojantshi abaseduze noma eminye imigwaqo emikhulu.
D. Izigaba ezihamba kancane lapho ububanzi bombhede womgwaqo bushintsha.
E. Izigaba lapho irediyasi yejika ingaphansi kwerediyasi encane.
F. Izigaba zomzila wokushintsha isivinini ezindaweni zesevisi, izindawo zokupaka noma ezitobhini zamabhasi, kanye nezigaba ezifakwe ezindaweni ezingunxantathu lapho uthango nezinsimbi zokuvikela zihlukanisa futhi zihlanganise ithrafikhi.
G. Ukuxhumana phakathi kwemikhawulo yamabhuloho amakhulu, aphakathi nendawo namancane noma iziphetho zezakhiwo eziphakeme kanye nombhede womgwaqo.
H. Lapho kuthathwa njengesidingo ukumisa ama-guardrails eziqhingini eziphambukisayo naseziqhingini ezihlukene.
