Ukuhamba kwezithuthi ngendlela ehlelekileyo kwiindawo ezidibana kuzo iidolophu kuxhomekeke kwinkxaso ezinzileyo yezibane zendlela. Ke ngoko, ukukhetha indlela efanelekileyoiipali zemiqondiso yendlelalinyathelo elibalulekileyo kumanqanaba okuqala okwakhiwa kwendlela. Ukukhethwa kweepali akufuneki kusekelwe kuphela kwinkangeleko; kufuna ukuqwalaselwa ngokupheleleyo kobukhulu bendawo edibana kuyo, indlela yokufakela, iimeko zomthwalo, kunye nokusingqongileyo kwendawo.
Xa kufikwa ekukhetheni okulungileyoiipali zemiqondiso yendlelaKukho iintlobo ezimbalwa ekufuneka uziqwalasele. Unayo eyakhoiipali zezibane zethrafikhi ezimacala mathandathu, iipali zezibane zendlela ezijijekileyokunyeiipali zezibane zethrafikhi ezizinxantathu, nganye inamandla ayo.Izibonda zesignali zendlela ezi-octagonalziyindlela ethandwayo yokukhetha iindlela eziqhelekileyo zokudibana kuba ziyakwazi ukumelana noxinzelelo ngokulinganayo kwaye zinemilo ecocekileyo nelinganayo.Izibonda zeempawu zendlela ezijijekileyoKwelinye icala, zibukeka zintle kwaye zihlala zisetyenziswa kwiindlela ezintle okanye ezitalatweni ezinkulu ezidolophini.Iipali ezizinxantathuZinamandla kakhulu kwaye ziyakwazi ukusingatha imithwalo enzima, nto leyo ezenza zilungele iindawo ezinkulu ezidibana kuzo ezinezibane zendlela ezininzi kunye nezixhobo. Emva koko kukho ezi freyimu ze-gantry ezidityanisiweyo, ezifana nesisombululo esiphezulu kwiindawo ezinkulu ezidibana kuzo iindlela ezininzi - zinokubamba iiseti ezininzi zezibane zendlela kunye nezixhobo zokubeka esweni ngaxeshanye. Ngoko ke, ukuze ufumane uhlobo lwepali olufunayo, kufuneka uqale umisele uhlobo lwayo lolwakhiwo. Oku kuya kukunceda ukhethe ukuba yeyiphi efanelekileyo kwimeko yakho ethile. Nokuba ujongene nendawo exakekileyo okanye indlela entle, ukukhetha iipali zezibane zendlela ezifanelekileyo kubalulekile kukhuseleko nokusebenza kakuhle. Ngokuqwalasela iintlobo ezahlukeneyo zeepali kunye neempawu zazo, ungenza isigqibo esinolwazi kwaye ufumane izixhobo ezifanelekileyo zomsebenzi.
Xa kufikwa ekukhetheni okulungileyoubude be-cantilever, yinxalenye ebalulekileyo yenkqubo. Inani leendlela endleleni lidlala indima enkulu ekugqibeni ukuba i-cantilever kufuneka ibe mide kangakanani. Umzekelo, ukuba ujongene ne-indlela eneendlela ezimbini, aubude be-cantilever yeemitha ezi-3-5lukhetho olufanelekileyo. Kwelinye icala, ukuba usebenza ne-indlela eneendlela ezine, uya kufuna ukuhamba neubude be-cantilever yeemitha ezi-6-8Kwaye kwiindlela eziphambili ezineiindlela ezintandathu nangaphezulu, aubude beemitha ezili-9-12Kuhlala kucetyiswa. Kodwa nantsi into: ukuba wenza i-cantilever ibe nde kakhulu, inokubangela iingxaki. Umzuzu wokugoba kwepali uyanda, oko kuthetha ukuba kuya kufuneka uqinise udonga lombhobho ukuze uthintele ukuba lungagobi kwaye luguquguquke ngokuhamba kwexesha. Kubalulekile ukuqinisekisa ukuba kukho umgama owaneleyo wokhuseleko ukugcina izibane zendlela zingaphezulu komgaqo, ngaphandle kwemiqobo efana nemithi okanye ii-overpasses eziphazamisayo. Oku kubalulekile ekuqinisekiseni ukuba yonke into ihamba kakuhle nangokukhuselekileyo. Ngoko ke, xa ubala ubude be-cantilever, kufuneka uzithathele ingqalelo zonke ezi zinto. Akupheleli nje ekubetheni ezinye izibane zendlela uze uzibize ngosuku - kufuneka ucinge ngononophelo malunga neenkcukacha zendlela kunye nezithuthi eziza kuyisebenzisa. Ngokwenza njalo, ungenza inkqubo ekhuselekileyo nesebenzayo esebenza kakuhle kuwo wonke umntu.
Izinto ezenziwe ngazo iipali kunye nendlela ezikhuselwe ngayo kumhlwa zibalulekile xa kufikwa ekubeni zihlala ixesha elingakanani. Ngokwesiqhelo, iipali zesignali zendlela zenziwa ngohlobo lwentsimbi ebizwa ngokuba yiQ235, kwaye bakhuselwe ngenkqubo ebizwa ngokubaukuntywila okushushu, okanye ngamanye amaxesha oko kulandelwa lolunye ungqimba lokhuseleko olubizwa ngokubai-electrostatic powder coatingKodwa kwiindawo ezikufutshane nolwandle okanye imilambo, apho umoya unetyuwa kwaye unokugqwala iipali, kungcono ukusebenzisa iileya ezimbini zokukhusela –ukuntywila okushushukwayeumgubo wokugquma– ukuze zingagqwali. Kwizixeko ezikude kakhulu, umaleko omnye we-hot-dip galvanizing udla ngokwanela. Into kukuba, izithuba zemiqondiso yendlela ezihlala ngaphandle ngalo lonke ixesha, ziniwa kwaye zihleli elangeni, ziya kuqala ukugqwala ukuba azikhuselekanga kakuhle ngokwaneleyo, kwaye oko kunokuba yingxaki yokhuseleko. Ngoko ke, kubaluleke kakhulu ukusebenzisa izixhobo ezifanelekileyo kunye neendlela zokukhusela ukuqinisekisa ukuba iipali zihlala ixesha elide kwaye zihlala zikhuselekile.
Iimeko zomthwalo wendalo azinakungahoywa. Iingingqi ezahlukeneyo zineemfuno ezithileukumelana nomoyaIindawo ezisemathafeni zihlala zihlangabezana nomgangatho wokuxhathisa umoya27 m/s, ngelixa iindawo ezithandwa zizivuthuvuthu zifuna umgangatho36 m/sokanye ngaphezulu. Xa ufaka izixhobo ezininzi, ubunzima obupheleleyo bezibane zendlela, iikhamera, kunye neendawo zokuhlala kufuneka bubalwe ukuze kuthintelwe ukugqithisa kakhulu. Isiseko kufuneka sihambelane neepali; iipali eziphakamileyo ze-cantilever zifuna iibholithi ezinkulu ze-ankile kunye neziseko zekhonkrithi.
Xa kufikwa ekumiseni izibane zendlela, zininzi izinto ekufuneka uzicinge. Akupheleli nje kwimithetho, kodwa nakwindlela ezibonakala ngayo. Umzekelo, kwiidolophu ezincinci, ungazixhoma nje eludongeni. Kodwa kwizixeko ezikhulu, izithuba zemiqondiso yendlela kufuneka zihambelane nesitayile kunye nombala wesixeko. Yonke inkqubo ilandela izikhokelo ezingqongqo ukuqinisekisa ukuba yonke into ikhuselekile kwaye isebenza kakuhle. Azisebenzisi iipali ezibhityileyo kakhulu okanye ezingahlangabezani nemigangatho. Injongo kukukhetha iipali zezibane zendlela ezenza umsebenzi wazo kwaye zihlala ixesha elide, ukuze ungachithi mali eninzi uzilungisa kamva. Ngale ndlela, izithuthi zihlala zihamba kakuhle nangokukhuselekileyo.
Qixiangyenza zonke iintlobo zeiipali zezibane zendlela, njengeentlobo ezi-octagonal, ezo zi-conical, kunye nezinkuluiipali ze-gantryIzithuba zethu zemiqondiso yendlela zenziwe ngezixhobo eziqinileyoIntsimbi ye-Q235kwaye sizikhusela kumhlwa ngesixhobo esikhethekileyoukuntywila okushushukunye nenkqubo yokugquma umgubo. Ukuba ufuna ipali yesignali yendlela enobude obuthile bengalo okanye ufuna ikwazi ukumelana nemimoya enamandla, singakwenza oko. Sinobukhulu neentlobo ezahlukeneyo, kwaye iipali zethu zakhiwe ukuze zihlale ixesha elide. Ungazifumana neebholithi zeankile ukuze ukhuseleke ngakumbi. Ukuba ufuna iipali zesignali yendlela ezilungileyo, sazise nje into oyifunayo kwaye siya kukunyamekela - sijolise ekuboneleleni ngezisombululo ezilungileyo zeendlela.
