Kufuneka ukwazi ukuthenga ingqiqo ethileucingo olunomnatha
Baninzi abasebenzisi abasebenzisayoucingo olunomnatha wocingonjengeingcingo zodwa. I-Guardrail net luhlobo lwendlela yentsimbi yokugada. Ulwakhiwo lwalo kukwahlula ikholomu yokuqala ye-guardrail kwiindawo eziphezulu nezisezantsi. Isiphelo esisezantsi sombhobho wentsimbi wekholamu ephezulu sinemikhono kwisiphelo esiphezulu sombhobho wentsimbi wekholamu engezantsi, kwaye iibholiti zidlula kuyo ukuze zidibanise imibhobho yentsimbi ephezulu kunye nesezantsi. Isebenzisa i-casing okanye ezinye iindlela zokuthintela ukuguqulwa kwesithuba sokugada esisezantsi ngokomeleza ikholamu esezantsi ethe tye, kwaye kwangaxeshanye yenze buthathaka ngokuyinxenye okanye yenze buthathaka ikholamu ephezulu ethe tye ukulawula indawo yoguqulo lwendawo yokugada. Ngale ndlela, nangona ingalo yamandla iyancipha, icandelo lomnqamlezo liyancitshiswa.
I-modulus ye-flexural nayo iyancitshiswa ngexesha elifanayo, ukwenzela ukuba kuqinisekiswe ukuba inqanaba lokuchasana ne-collision alikho ngaphantsi koyilo oluqhelekileyo oluqhelekileyo. Isefu yocingo lukaloliwe kuqala ukukhetha ucingo olugqityiweyo olutsalwa kwintonga yocingo olukumgangatho ophezulu; ukuwelda okanye ukwaluka, ubukhulu becala kuxhomekeke kwisakhono kunye nobuchule bokusebenza phakathi kwamagcisa kunye noomatshini abalungileyo bemveliso. I-mesh elungileyo yonke i-welding Okanye iindawo zokuluka zinokudityaniswa kakuhle; kunye nokukhethwa kwesakhelo kufuneka kube yintsimbi ye-angle ephezulu kunye nentsimbi ejikelezayo, kunye nentsimbi ye-angle kunye nentsimbi ejikelezayo esetyenziselwa iminatha yocingo eyahlukileyo kufuneka ihluke. Ukutshiza ngokubanzi kufuneka kuthathelwe ingqalelo. Ukufana kwengubo kunye nomgangatho wokugquma nazo zibalulekile. Iminatha yocingo ye-Expressway isetyenziselwa ukubiya koohola bendlela, oololiwe, izikhululo zeenqwelomoya, izikhululo, iindawo zenkonzo, iindawo ezidityanisiweyo, iiyadi zokugcina ezivulekileyo, amazibuko kunye nezinye iindawo. Iimveliso zayo zineengenelo zokuhombisa okusingqongileyo, zomelele kwaye zomelele, akukho lula ukucima kunye nokonakala. Nantsi intshayelelo emfutshane kwingqiqo eqhelekileyo malunga nokuthengwa kocingo ekufuneka uyazi:
Okokuqala, ubume beucingo olunomnatha: ucingo luhlulwe lube luhlobo lwesakhelo kunye nohlobo lwesakhelo. Uhlobo lwesakhelo sisakhelo esakhiwe ngumbhobho ophezulu malunga ne-mesh yensimbi kwaye idibene nenkxaso yekholomu; uhlobo olungenasiphelo luyintsimbi yensimbi edibaniswe ngokuthe ngqo kunye nentsimbi yensimbi; ixabiso guardrail kwakhona yahlukile ixabiso izakhiwo ezibini ezahlukeneyo guardrail umgangatho.
Okwesibini, ucingo locingo luvame ukwenziwa ngeengcingo ze-welding zenkcazo eyahlukeneyo. Ububanzi kunye namandla eengcingo zichaphazela ngokuthe ngqo umgangatho wegridi. Xa ukhetha ubuninzi becingo oluhambelana nawe, okwesibini yinkqubo ye-welding okanye yokuhlanganiswa kwegridi. Ikakhulu ixhomekeke kubuchule bobugcisa kunye nokusebenza kwamagcisa kunye noomatshini abalungileyo bemveliso. Ngokubanzi, i-mesh elungileyo kukuba yonke i-welding okanye indawo yokuluka inokudityaniswa kakuhle.
Okwesithathu, kubaluleke kakhulu ukukhetha ikholomu kunye nesakhiwo sesakhelo socingo. Ukutshatisa iikholamu kunye nezakhelo kuya kuthatha ixesha elide. Ngoko ke, indlela yokukhetha i-column frame material ibaluleke kakhulu. Kukho iintlobo ezintathu ezahlukeneyo: intsimbi yesikwere, ihexagon kunye nengqukuva. Amandla ocingo lomda ahluke. Isitshixo yindlela yokukhetha i-column frame material, ebunzima bubonke bobunzima bekholamu yangaphakathi, isixa sokutyekela ngasemva, kunye nesixa se-prepreg. Zonke ezi ziqondwa.
Okwesine, unyango olungaphezulu kocingo luhluke kwi-spray forming, i-galvanizing ebandayo kunye ne-galvanizing eshushu, kunye nomgangatho wepowder yeplastiki ihambelana ngqo nobomi benkonzo.
Ngentshayelelo engentla, ndiyathemba ukuba unokuthenga ucingo ngoncedo. IBofengucingo olunomnathaI-Factory apha ikhumbuza ukuba ungathengi iimveliso eziphantsi kwexabiso eliphantsi, kodwa kwakhona ukuba ubeke ingqalelo kumgangatho wezinto eziphathekayo, kuba umgangatho wezinto eziphathekayo uchaphazela ngokuthe ngqo umgangatho kunye nobomi benkonzo yemveliso, kunye nomgangatho wemveliso.
