Izithiyo zokuphahlazeka zifakwa uthango maphakathi noma ezinhlangothini zombili zomgwaqo ukuvikela izimoto ukuthi ziphumelele umgwaqo noma ziwela i-Median ukuvikela ukuphepha kwezimoto nabagibeli.
Umthetho Wezwe Wezwe Yezwe lethu unezidingo ezintathu eziphambili zokufakwa kwama-Guardrails alwa nokushayisana:
(1) Ikholomu noma i-Guardrail of the Crash GuardRail kufanele ihlangabezane nezidingo zekhwalithi. Uma usayizi wayo ungahlangabezani nezidingo, ubukhulu besendlalelo se-galvanized akwanele, futhi umbala awufani, kungenzeka ukuthi kubangele izingozi zomgwaqo.
. Uma ingaphandle lehlombe lomgwaqo lenhlabathi lisetshenziswa njengereferensi ye-Stakeout, lizothinta ukunemba kokuqondanisa kwekholomu (ngoba inhlabathi edondoyo ayikwazi ukuba umfaniswano ububanzi ngesikhathi sokwakha). Ngenxa yalokhu, ukuhambisana kwekholomu kanye nokuqondisa kwendlela akuhlanganisiwe, okuthinta ukuphepha kwezimoto.
(3) Ukufakwa kwekholomu kwe-Crash GuardRail kuzohlangabezana nezidingo zekhwalithi. Isikhundla sokufaka sekholomu kufanele sibe ngokuqinile ngokuhambisana nomdwebo wokuqamba kanye nesikhundla sokukhahlela, futhi kufanele sixhumane nokuqondanisa komgwaqo. Lapho indlela yokumbiwa isetshenziselwa ukungcwaba amakholomu, ukugcwaliswa kwe-bacleall kuzohlanganiswa ezingxenyeni ezinhle (ubukhulu besendlalelo ngasinye ngeke kudlule i-10cm), futhi izinga lokuhlangana kwe-backfulf ngeke libe ngaphansi kwenhlabathi engaphazamiseki. Ngemuva kokuthi ikholomu ifakiwe, sebenzisa i-The Theodolite ukukala bese uyilungisa ukuze uqinisekise ukuthi umugqa uqondile futhi bushelelezi. Uma ukuhambisana kungaqiniseki ukuthi kuqondile futhi bushelelezi, kuzothinta ngokungenakuphikiswa ukuphepha kwezimoto zomgwaqo.
Uma ukufakwa kwe-Crash Barrier kungajabulisa iso, kuzothuthukisa kangcono induduzo yokushayela futhi kunikeze abashayeli ngesiqondiso esihle sokubuka, ngaleyo ndlela kunciphise ukwenzeka kwezingozi nokulahleka okubangelwa yizingozi nokulahleka okubangelwa izingozi.
