Pakuisa marata ekurinda mumigwagwa mikuru, akati wandei maficha anoda kunyatsotariswa:
(1) Post-Impact Deformation
Iyo yakanyanya dynamic deformation yeguardrail mushure mekukanganisa haifanirwe kudarika inobvumirwa clearance pakati peguardrail uye chinhu chakadzivirirwa.
(2) Kuenderana Kwezvinhu
Iyo guardrail, materminals ayo ekupedzisira, uye shanduko kune mamwe marudzi egadhirail anofanirwa kushandisa zvakamisikidzwa zvinhu kuti zvive nyore kuisa uye kugadzirisa.
(3) Site Conditions
Zvinhu zvakadai semapfudzi uye upamhi hwepakati, pamwe nemateru emumugwagwa, zvinogona kukanganisa kukodzera kwemamwe marudzi evarindi kune imwe nzvimbo.
(4) Hupenyu-Kutenderera Mutengo
Kupfuura mari yekutanga kuvaka, funga nezvenguva refu yekugadzirisa mari. Dzivisa kukanganisa kunaka kwemitengo yakaderera yekumusoro, sezvo substandard garairi dzinowanzoita ngura nguva isati yakwana uye dzinogona kutadza kuongororwa.
(5) Kuparara
Iyo guardrail yakasarudzwa inofanirwa kunyatso tora simba rekuita, kudzivirira mota dzakarasika kubva munzira kana kuyambuka munzira dziri kuuya, uye dzodzoreredza dzakachengeteka. Matanho akasiyana ekuputsika anodiwa pamhando dzemigwagwa dzakasiyana. Semuenzaniso, migwagwa yekumaruwa inogona kushandisa B kana C class corrugated guardrails, nepo migwagwa mikuru ichida A kana SB makirasi ekurinda ane yakanyanya kupikisa.
(6) Kuchengeta Zvinodiwa
Funga nezvekureruka uye kuwanda kwekugadzirisa, kuisa mukuchengetedza kwenguva dzose, kugadzirisa tsaona, kuwanikwa kwezvinhu, uye kuwanikwa kwevashandi vekugadzirisa.
(7) Kuitwa Kwenharaunda
Dzidza kubva kune iripo guardrail kumisikidzwa munzvimbo uye dzivirira kudzokorora dhizaini yakapfuura kana sarudzo dzezvinhu dzakaratidza kusashanda.
(8) Aesthetics uye Environmental Factors
Funga nezvemaonerwo anoitwa guardrail panzvimbo yakapoteredza. Account yezvakatipoteredza zvakaita se corrosion potential, mamiriro ekunze, uye gadhirail kukanganisa pakuona kwevatyairi.
Nekunyatsogadzirisa zvinhu izvi panguva yekuronga uye yekuisa matanho, unogona kuve nechokwadi chekusarudzwa uye kuitiswa kwemarara ekuchengetedza marara anosimbisa kuchengetedzeka kwemigwagwa uye kusangana nezvinodiwa zvenzvimbo yemugwagwa mukuru.
