Ezingqalasizinda zasemadolobheni, ukuphepha komphakathi kanye nokuphathwa kwezimoto, indima yama-bollard ayinakunakwa. Anesibopho sokuhlukanisa izindawo, ukuvimba izimoto nokuvikela abahamba ngezinyawo. Phakathi kwezinto eziningi, ama-bollard ensimbi engagqwali kancane kancane aba ukukhetha kokuqala kwezindawo zokuvikela zasemadolobheni ngokusebenza kwawo okuhle kakhulu okuphelele.
Okokuqala, inzuzo evelele kakhuluamabhodi ensimbi engagqwaliukumelana kwazo okuhle kakhulu nokugqwala. Insimbi engagqwali ngokwayo inamandla amakhulu okulwa ne-antioxidant futhi ayigqwali kalula yizindawo zemvelo ezifana nemvula, umswakama noma i-salty spray. Ifaneleka kakhulu ezindaweni ezisogwini noma ezindaweni zasemadolobheni ezinomswakama ophezulu womoya. Uma kuqhathaniswa nama-bollards ekhonkrithi, insimbi engagqwali ayigqwali yimvula, futhi ayibi nomoya noma iqhekeke; kuyilapho ama-bollards epulasitiki ethambekele ekugugeni, ekubuneni nasekuqhekekeni ngemva kokuchayeka isikhathi eside elangeni nasemoyeni nasemvuleni.
Okwesibili,amabhodi ensimbi engagqwalibanokumelana okuqinile nesimo sezulu. Kungakhathaliseki ukuthi kubanda kakhulu noma ukushisa, noma imisebe enamandla ye-ultraviolet, ama-bollard ensimbi engagqwali angagcina isakhiwo nokubukeka kwawo ngokuzinzile. Lokhu kuqina kunzima ukukufeza ngezinye izinto, ikakhulukazi ama-bollard epulasitiki, avame ukuguquka nokuqhekeka ngaphansi kokukhanya okunamandla nezimo zokushisa okuphezulu, kuyilapho ama-bollard ekhonkrithi angaba nokuqhekeka kobuso noma imifantu yangaphakathi ngemva kokushintshana ngokushisa nokubanda.
Ngokuphathelene nokumelana nokushayisana,amabhodi ensimbi engagqwaliIsebenza kahle ngokulinganayo. Isakhiwo sayo siqinile futhi singamelana ngempumelelo nokushayisana kwezimoto ngaphandle kokulimala kalula. Ngokuphambene nalokho, nakuba ukhonkolo ubonakala uqinile, uvame ukuphuka noma ukuphuka ngisho nalapho kushayisana ngamandla, okushiya inani elikhulu lemfucumfucu. Ama-bollard epulasitiki awakwazi ukumelana nokushayisana okukhulu ngenxa yamandla awo aphansi, futhi avame ukugoba noma ukudilika ngokushesha ngemva kokushayisana.
Ngaphezu kwalokho,amabhodi ensimbi engagqwalifuthi inobuhle obuqinile bokubona. Ngokupholisha isibuko, ukucutshungulwa ngebhulashi kanye nezinye izindlela, ayigcini nje ngokuba nomuzwa wesimanje, kodwa futhi ingahlanganiswa kahle nezindawo zezentengiselwano ezisezingeni eliphezulu, izikwele zamadolobha kanye nezindawo zesimanje zokwakha. Ngokuphambene nalokho, ama-bollard ekhonkrithi akhulu futhi aqinile ngokubukeka, asetshenziswa kakhulu ezigcawini ezisebenzayo, futhi cishe awadingi ukwakheka okuhle. Nakuba ama-bollard epulasitiki angathuthukisa ukubonakala ngombala, izinga lokubonakala lilonke liphansi.
Ngokufigqiwe,amabhodi ensimbi engagqwalisezibe yisinqumo esifanele sezindawo zokuvikela zasemadolobheni ngenxa yezinzuzo zazo eziningi ezifana nokumelana nokugqwala, ukumelana nesimo sezulu, ukumelana nokushayisana, kanye nokubukeka okuhle. Nakuba izindleko zazo zokuqala ziphakeme kancane, ngokuhamba kwesikhathi, ukuqina kwazo okuphezulu kanye nezidingo zokunakekelwa okuphansi kunganciphisa ngempumelelo izindleko zokusebenza zizonke, okwenza kube utshalomali oluhlanganisa ukusebenza nobuhle.
