Indlela yokwenza iipali zesignali zendlela zangaphandle zihlale ixesha elide

Izibonda zeempawu zendlela zangaphandleZichatshazelwa zizinto ezibangela imozulu ixesha elide kwaye zichatshazelwa ngumoya, imvula, ilanga, iqabaka, kunye nezivuthuvuthu zesanti. Ekuhambeni kwexesha, oku kunokukhokelela ekugqwaleni nasekuguquguqukeni. Ukhuseleko olufanelekileyo lwemihla ngemihla kunye nokugcinwa kwazo kunokwandisa ubomi bezi zibonda zezibane zendlela, ukuqinisekisa ukhuseleko lwendlela kunye nokunciphisa iindleko zokutshintshwa. Nazi ezinye iingcebiso ezisebenzayo zokulungisa ngaphandle malunga nezibonda zezibonakaliso ze-galvanized.

I. Ufakelo oluQhelekileyo lweSiseko Esihlala Sihleli

Umgangatho wofakelo yimfuneko yokusetyenziswa ixesha elide kweepali zokukhanyisa zemiqondiso yendlela. Okokuqala, qinisekisa ukuba isiseko sigalelwe kwimigangatho eqhelekileyo, kunye nemilinganiselo yesiseko kunye nobunzulu benxalenye efakwe ngaphakathi ihlangabezana nemigangatho yesizwe ukuthintela ukukhululeka okanye ukuthambeka kwesiseko okunokubangela ukuguquka kweepali. Okwesibini, ipali kufuneka ithe tye kwaye i-cantilever iqine ngexesha lokufakwa. Zonke izikrufu kunye neebholithi kwi-flange kufuneka zifakwe ngokuqinileyo ukuze kuthintelwe uqhagamshelo olukhululekileyo. Okokugqibela, ngexesha lokwakhiwa, lumka ungakrweli i-powder coating. I-powder coating eyonakeleyo ngumthombo omkhulu wokugqwala. Ulwazi olufanelekileyo lofakelo lunokunciphisa kakhulu ukusilela kwixesha elizayo.

II. Ukucoca rhoqo ukuze kuncitshiswe ukugqwala kwindalo esingqongileyo

Ngaphezu koko, uthuli, ioyile, amagqabi awileyo, kunye nokungcola okune-asidi/i-alkaline kuqokelelana ngokulula phezu kweepali zangaphandle, kwaye ukunamathela ixesha elide kunokonakalisa uqweqwe lomphezulu. Sula ipali yokukhanyisa yesignali yendlela rhoqo ngamanzi acocekileyo kunye nelaphu elithambileyo ukususa ukungcola komphezulu kunye nenkunkuma. Iipali ezikufutshane neendawo zokwakha, iindawo ezikunxweme, okanye kwiindawo zoshishino, apho ungcoliseko kunye nokugqwala kukhulu khona, kuya kufuneka zicocwe rhoqo. Musa ukusebenzisa izicoci ze-asidi enamandla okanye i-alkali, njengoko zinokukonakalisa uqweqwe lomgubo kwaye zonakalise isakhiwo sokulwa nokugqwala kwepali yomqondiso we-galvanized.

III. Ukuhlolwa Kwamaxesha Ngamaxesha kunye Nokulungiswa Kwangoko Kweziphene

Yenza uhlolo nolondolozo rhoqo, ugxile kwiindawo ezintathu eziphambili: Okokuqala, umphezulu wepali yesignali yendlela: Jonga ukuba akukho mgubo oxobukayo, imikrwelo, kunye namabala okugqwala. Ncamathelisa umonakalo omncinci ngokukhawuleza ngepeyinti ekhethekileyo yokuchukumisa yangaphandle ukuze uthintele ukusasazeka komhlwa. Okwesibini, ezantsi kweeflanges kunye namalungu adibeneyo: ezi ziindawo apho amanzi kunye nomhlwa kunokwenzeka ukuba ziqokelelene khona, kwaye kufuneka zihlolwe ngononophelo. Okwesithathu, ukulungisa izikrufu kunye nezibiyeli: jonga ukuba zikhululekile na kwaye zinomhlwa, kwaye uqinise ngokukhawuleza okanye utshintshe iindawo ukuze uthintele ukushukuma kunye nomonakalo wepali.

IV. Ukhuseleko Olukhethekileyo Ngaphambi Nasemva Kwemozulu Embi

Imozulu embi kakhulu efana nemvula enkulu, iinkanyamba, kunye neqabaka ibangela umonakalo omkhulu kwiipali. Ngaphambi kwenkanyamba, jonga ukuqina kweepali kwaye uqinise naziphi na iindawo ezikhululekileyo. Jonga isiseko samanzi kunye nomhlwa emva kwemvula enkulu, kwaye ususe nawaphi na amanzi kunye nedaka eliqokelelweyo. Ebusika, kumaqondo obushushu aphantsi kunye neqabaka, musa ukuvumela iipali ukuba ziqine kwaye zande, nto leyo enokonakalisa uphahla. Ukususwa kwekhephu ngexesha elifanelekileyo kunokuthintela ngempumelelo ukubanda, ukuqhekeka, ukubola, kunye nokuguquka kwaye kwandise kakhulu ubomi benkonzo yeepali zesignali ze-galvanized.

I-Qixiang ibisebenza kwishishini lezixhobo zendlela kangangeminyaka emininzi kwaye igxile ekuveliseni zonke iintlobo zeepali zemiqondiso yendlela zangaphandle.iipali zesignali ze-galvanizedZenziwe ngeetyhubhu ezisemgangathweni kazwelonke ezijiyileyo, ezenza ziqine kwaye zizinzile. Ziphathwa kabini ukuze zingagqwali: i-hot-dip galvanizing kunye ne-outdoor electrostatic powder coating, ngoko ke ziyamelana nelanga, imvula, kunye nemimoya enamandla ngaphandle kokuguquka. Imveliso ihambelana ngokungqongqo nemigangatho yobunjineli bemasipala; ii-welds ziqinile, imilo iqhelekile, kwaye iinkcukacha ziphelele kwaye zinokwenziwa ngokwezifiso. Zihlala ixesha elide kwaye zinobomi obude benkonzo kwaye zizinto ezikhethwayo zokwakha iziseko zendlela.
