Ekuphathweni kwethrafikhi, enye yezinto ezibaluleke kakhulu yi-isigxobo serobhothi. Lezi zakhiwo zigcina ngokuqinile amarobhothi, ziqinisekisa ukubonakala kwawo nokusebenza emgwaqeni. Kodwa uke wazibuza ukuthi zenziwa ngani izigxobo zamarobhothi? Kulesi sihloko, sibheka ngokujulile izinto ezisetshenziselwa ukwakha lezi zingxenye ezibalulekile zezinhlelo zokulawula umgwaqo.
Kunezinhlobo eziningi zezigxobo zesignali yomgwaqo, okuhlanganisa:
Izigxobo Ezijwayelekile:
Lezi yizinhlobo ezivame kakhulu zezigxobo zesignali yethrafikhi, ngokuvamile ezenziwe ngensimbi noma i-aluminium, futhi zenzelwe ukuhlalisa amakhanda esignali yomgwaqo nezinye izinto zokusebenza.
Izigxobo zokuhlobisa:
Lezi izigxobo eziklanywe ngobuhle, ezivame ukusetshenziswa ezindaweni zasemadolobheni noma izifunda ezinomlando ukuze zihlangane nezakhiwo ezizungezile noma ukwakheka kwezwe.
Izigxobo zeCantilever:
Lezi zigxobo zisetshenziselwa ukusekela izimpawu noma amasiginali aphezulu futhi zinwebe ngokuvundlile zisuka esakhiweni sosekelo esisodwa kunokuba zigxunyekwe ziqonde phezulu.
Izinduku Ezihlanganisiwe:
Lezi zinduku ziklanyelwe ukugoba noma ukudilika kumthelela, ukunciphisa amathuba okulimala okubi kakhulu noma ukulimala engozini.
I-Middle Mast:
Lezi zigxobo ezinde zisetshenziswa emigwaqweni emikhulu noma emigwaqweni ebanzi edinga ukuphakama okuphezulu ukuze kuthuthukiswe ukubonakala komshayeli.
Izigxobo ze-Jumper:
Lezi zigxobo zisetshenziselwa ukuvikela impahla yesignali yethrafikhi lapho isikhala noma izithiyo zikhawulelwe, njengasezimpambanweni zomgwaqo ezicijile noma ukufakwa phezulu. Lezi izibonelo ezimbalwa nje futhi nenani eliqondile lezinhlobo zezigxobo zethrafikhi lingahluka kuye ngemithetho yendawo kanye nezidingo ezithile zephrojekthi.
Izigxobo zokukhanya kwethrafikhi ngokuyinhloko zenziwe ngezinto ezimbili: insimbi ne-aluminium. Impahla ngayinye inezindawo ezihlukile futhi ifanele izindawo ezihlukene zasemadolobheni nezasemaphandleni.
Insimbi yinto evame ukusetshenziswa ngamandla ayo kanye nokuqina. Insimbi evame ukusetshenziselwa izigxobo zokukhanya kwethrafikhi ivamise ukuba namandla aphezulu e-carbon steel njenge-Q235/Q345. Lezi zinsimbi zaziwa ngokuhlala kwazo isikhathi eside, amandla aphakeme okudonsa kanzima, nokumelana nesimo sezulu. Ukwengeza, izinsimbi ezithathiwe zivame ukusetshenziswa ezigxotsheni zokukhanya kwethrafikhi ukuze zinikeze ukumelana nokugqwala futhi andise ukuphila kwazo. Iyakwazi ukumelana nesimo sezulu esibi futhi imelana kakhulu nokugqwala. Izigxobo zamarobhothi ensimbi ngokuvamile zipendwe ngothayela noma zipendwe ukuze kuvinjelwe ukugqwala emvuleni, eqhweni, noma ekukhanyeni kwelanga. Ngaphezu kwalokho, insimbi iwumsebenzi oguquguqukayo oguquguqukayo ekwakhiweni, okwenza kube lula ukuzivumelanisa nezakhiwo zemigwaqo ehlukahlukene.
I-Aluminium ingenye into evame ukukhethwa ezigxotsheni zamarobhothi. Inezinye zezimfanelo zensimbi, njengokuqina nokumelana nokugqwala. Nokho, i-aluminium ilula futhi ithambile, okwenza kube lula ukuyifaka nokuyihambisa. Ngaphezu kwalokho, izigxobo ze-aluminium zibukeka kahle futhi zanamuhla ezithuthukisa ubuhle be-cityscape. Kodwa-ke, ngenxa yesisindo se-aluminium esilula, kungenzeka ingazifanele izindawo ezinomoya omkhulu noma isiminyaminya.
Ngombono wami
Umkhiqizi wezigxobo zethrafikhi u-Qixiang ukholelwa ukuthi ukukhethwa kwezinto zesigxobo sethrafikhi kufanele kusekelwe ezidingweni ezithile kanye nezimo zendawo. Ezindaweni zasemadolobheni kakhulu lapho ubuhle bubaluleke kakhulu, izigxobo ze-aluminium zingase zibe yinketho yokuqala ngenxa yokubukeka kwazo kwesimanje. Ngakolunye uhlangothi, ezindaweni ezivame ukuba nesimo sezulu esibi kakhulu noma isiminyaminya, izigxobo zensimbi zinganikeza amandla adingekayo nokuhlala isikhathi eside.
Ekuphetheni
Izigxobo zezibani zethrafikhi ziyingxenye ebalulekile yohlelo lokulawulwa kwethrafikhi, oluqinisekisa ukuphepha nokusebenza kahle kwabasebenzisi bomgwaqo. Izinto ezisetshenziselwa ukwakha izigxobo, okuhlanganisa insimbi ne-aluminium, zikhethwe ngokucophelela ngenxa yezakhiwo zazo eziyingqayizivele nokufaneleka kwezindawo ezahlukene. Ukunquma ukuthi iyiphi into ezosetshenziswa kufanele icabangele izici ezifana namandla, ukuqina, ubuhle, kanye nokusebenza kahle kwezindleko. Ngokukhetha izinto ezifanele kakhulu, singaqinisekisa ukuthi izigxobo zamarobhothi zifeza indima yazo ngempumelelo ezimpilweni zethu zansuku zonke.
Uma unentshisekelo ezigxotsheni zethrafikhi, wamukelekile ukuthintana nomkhiqizi wezigxobo zethrafikhi u-Qixiang ukuzeFunda kabanzi.
