Izibane zendlela ezisebenza ngombanezingaphandle ixesha elide. Abalawuli besignali kunye neepaneli zokukhanya zinokonakala ngokulula ngenxa yokubetha kombane kunye nemisinga ebangelwayo. Ukhuseleko lombane kwiindawo ezidibana kuzo luxhomekeke kumhlaba ofanelekileyo wokukhusela umbane.
I. Yenza itshaneli yokukhupha umbane ethembekileyo emhlabeni
Izixhobo zokumisa umhlaba zifakelwe kunye nolwakhiwo lwesiseko sezibane ze-AC traffic signal, kwaye ii-electrode zokumisa umhlaba ziyintsimbi ye-galvanized angle kunye nentsimbi ye-galvanized flat. Ipali nganye iqhutyelwa emhlabeni ngeentsimbi ezimbini ze-galvanized angle ezinobude obuyi-2.5 m, ubuncinane ubude obuyi-5 m. Emva koko zidityaniswa ngokuthe tye ngentsimbi ye-galvanized flat eshushu ediphiweyo eyi-40 × 4 mm ukwenza igridi yokumisa umhlaba enemilo esangqa. Iindawo ezidibeneyo zentsimbi ye-flat steel zidityaniswa kwaye zigqunywe nge-asphalt ukuthintela ukugqwala. Ubunzulu bokungcwaba bulawulwa ngaphantsi kwe-0.7 m, kuthintelwa ukuba umhlaba ungahambi kakuhle njengegrabile kunye nesanti eyomileyo. Ukuzalisa i-backfill nge-arhente yokunciphisa ukuxhathisa kwiindawo zomhlaba owomileyo kuya kunciphisa ukuxhathisa komhlaba. Ikhonkrithi eqinisiweyo ayinakusetyenziswa njengendawo enye ye-electrode zokumisa umhlaba ezizinikeleyo. Ukuqhutywa kwekhonkrithi akuzinzanga kwaye akunakukhupha i-voltage ephezulu ngokukhawuleza ngexesha lokubetha kombane.
II. Ukubopha Izixhobo Zonke Ukuze Kuthintelwe Umngcipheko Wokungaphumeleli Komahluko Onokubakho
Emva kokuba igridi yokumisa umhlaba yakhiwe, iipali, iibhokisi zemiqondiso, izindlu zezibane zemiqondiso, kunye neepayipi zesinyithi kufuneka zibotshelelwe kwi-equipotential bonding efanayo. Iziseko zeepali zesinyithi kufuneka zifakwe ngokuthembekileyo ngqo kwintsimbi ethe tyaba yokumisa umhlaba. Iibhokisi zokusasaza kunye neepayipi zemiqondiso kufuneka ziqhagamshelwe kwiipayipi ezinkulu zokumisa umhlaba kusetyenziswa iingcingo zokumisa umhlaba ezimthubi-luhlaza. Iingcingo zokumisa umhlaba zethusi maziqhagamshelwe kuzo zombini iziphelo zeepayipi zesinyithi ukuthintela ukuba iipayipi zingaxhonywa ekubangeleni i-voltage. Zonke iigridi zokumisa umhlaba kwindawo yokumisa umhlaba kufuneka ziqhagamshelwe ukwenza umzimba omnye onokubakho kuyo yonke indawo yokumisa umhlaba. Oku kuthintela ukugoba ngenxa yomahluko we-voltage phakathi kwezixhobo ezahlukeneyo nomhlaba ngexesha leemvula kwaye kuthintela umonakalo kwiiphaneli zezibane ze-LED kunye neebhodi zomama ezilawulayo. Izibane zesignali ezineeplastiki nazo zifuna ukuba izibiyeli zentsimbi zangaphakathi zixhonywe; intambo yangaphakathi yeeterminal zokumisa umhlaba ayinakushiywa.
III. Ukufakwa kweZikhuseli zokuHamba ukuze kunqunyulwe umbane obangelwa kukubethwa ngumbane
Izixhobo zokukhusela ukuvuza kufuneka zibonelelwe kuzo zombini iziphelo zokungena kwamandla ombane kunye neentambo zonxibelelwano zesignali. Isixhobo sokukhusela ukuvuza esiphambili siqhagamshelwe ngokwahlukeneyo kwiintambo eziphilayo, ezingathathi cala, kunye neziphantsi komhlaba kwi-220V mains power inlet kwibhokisi yokusasazwa kwesignali yethrafikhi. Kwintambo yenethiwekhi kunye nomgca wolawulo lonxibelelwano lwe-485, faka isikhuseli sokuvuza kwesignali kwaye uqhagamshele isheya yesinyithi yentambo yenethiwekhi ekhuselweyo emhlabeni kuzo zombini iziphelo. Zonke iintambo zomhlaba zesikhuseli sokuvuza ziqhagamshelwe ngqo kwiintambo zomhlaba, kwaye ubude be-lead bunqunyelwe ngaphakathi kwe-0.5 yeemitha ukunciphisa i-voltage eseleyo. Okuphambili kufuneka kunikwe ukuguqula iintambo ezingaphezulu zibe ziintambo ze-conduit ezingaphantsi komhlaba. Imigca engaphezulu ichaphazeleka kukubetha kombane okubangelwa yi-high-voltage. Iintambo ezingaphantsi komhlaba zinciphisa kakhulu amathuba okungena kombane. Iintambo zokungena kunye neendawo zokuphuma kwentambo kufuneka zithintelwe ngamanzi kwaye zivalwe ngokufanelekileyo ukuthintela amanzi emvula ukuba angangcolisi ii-terminals zesikhuseli sokuvuza.
IV. Ukulinganisa Ukumelana Nomhlaba Ophantsi Kwamaxesha Ngamaxesha kunye Nokugcinwa Emva Kokwakha
Xa ulwakhiwo lugqityiwe, ukumelana nokuma komhlaba kuvavanywa ngomatshini wokuvavanya ukumelana nokuma komhlaba.Izibane zendlela zikamasipalaKwiindawo zokunqumlana komhlaba zine-standard sustainment ≤4Ω. Ukuba i-resistance iphezulu kune-standard, kufuneka kongezwe ii-electrode ezongezelelweyo zokumisa umhlaba okanye izinto ezinciphisa i-resistance. Ngaphambi kwexesha ngalinye lemvula, yenza uhlolo lokujonga ukuba akukho mhlwa kwiindawo zokuwelda zentsimbi ezithe tyaba, iingcingo zokumisa umhlaba ezikhululekileyo okanye ezihlukanisiweyo, kunye nokuba mnyama okanye ukungasebenzi kakuhle kwezikhuseli zokuntywila. Imisele yokumisa umhlaba ingaqokelela amanzi ngexesha lemvula. Yisuse kwangoko emva kwexesha lemvula ukuze ii-electrode zokumisa umhlaba zingahlali emanzini ixesha elide kwaye zibole. Kwiindawo zokunqumlana ezindala ezilungiswayo, iigridi zokumisa umhlaba ezirhabaxa kufuneka zihlaziywe, kwaye iingcingo zokumisa umhlaba ezidala kufuneka zitshintshwe ukuthintela ukutsha kwezixhobo kunye neengozi zombane ezibangelwa kukusilela kwe-grounding.
I-Qixiang igxile ekwenzeniIzibane zesignali zetrafikhi ze-ACngokhuseleko lombane kunye noyilo lomhlaba. Siyakwamkela ukwenziwa ngokwezifiso, kwaye iipali zethu zifakwe i-hot-dip galvanized ukuze zikwazi ukumelana nokugqwala. Sinesibonelelo esizinzileyo, isisombululo esipheleleyo sokwakha nokulungisa, kunye namava amaninzi kwiiprojekthi zikamasipala.
