Njengoko ubukrelekrele boluntu busiya buthandwa ngakumbi, iingcingo zale mihla zifana nenkqubo yemithambo-luvo yomntu, inabela kuzo zonke iikona zesakhiwo.
Ngalo lonke ixesha wonke umntu esenza ubunjineli okanye iprojekthi, bacinga kuphela: Zingaphi iimodeli eziya kusetyenziswa kule projekthi?Zingaphi iimitha zentambo ekufuneka zisetyenziswe?
Kukho iimodeli ezininzi zeengcingo kunye neentambo, kodwa ukuxhathisa kwabo komlilo kunye neemfuneko ze-flame retardant ziye zangahoywa ngabantu, okuye kwaba yingozi enkulu efihliweyo yomlilo.
Ngoko ke ungakhetha njani ukumelana nomlilo kunye nebanga lokungatshatyalaliswa komlilo kwiingcingo kunye neentambo kuyilo lobunjineli beprojekthi?Eli nqaku libonelela ngezi ngcebiso zilandelayo kwireferensi yakho:
Indawo yokubeka ikhebula
Indawo yokubeka intambo imisela ubukhulu becala ukuba intambo iya kuhlaselwa yimithombo yomlilo yangaphandle kunye nokwenzeka kokutsha okulibazisekayo kunye nentlekele emva komlilo.
Ngokomzekelo, iintambo ezingenakunqanda zingasetyenziselwa ukungcwaba ngokuthe ngqo okanye iipayipi ezihlukeneyo (isinyithi, i-asbestos, iipayipi zesamente).
Ukuba intambo ifakwe kwibhulorho evaliweyo, i-trunking okanye umsele okhethekileyo wekhebula (enesigqubuthelo), iimfuno zokunqanda ilangatye zinokuncitshiswa ngokufanelekileyo ngamanqanaba amabini ukuya kumabini.Kucetyiswa ukuba usebenzise iKlasi C yokubuyiswa komlilo okanye iKlasi D yokuRetardant.
Ngenxa yokuba mancinci amathuba okuba uhlaselwe zizinto zangaphandle kule ndawo, nokuba ibamba umlilo ngenxa yesithuba esimxinwa kunye nesivalekile, kulula ukuzicima kwaye akunakwenzeka ukuba kubangele. a intlekele.
Ngokuchasene noko, inqanaba le-flame retardant kufuneka linyuswe ngokufanelekileyo ukuba umlilo ubonakaliswe ngaphakathi, ukuba igumbi liyenyuka ngesakhiwo, okanye kwindawo eyimfihlo, i-mezzanine, okanye i-tunnel paseji, apho umkhondo kunye nomlilo zifikeleleka ngokulula kwaye indawo inkulu kwaye umoya unokujikeleza lula.Kuyacetyiswa ukuba ukhethe udidi B olubuyiswa ngamadangatya okanye udidi A olugada amadangatye.
Xa imeko-bume ekhankanywe apha ngasentla iphambi okanye emva kweziko lobushushu obuphezulu okanye kwimichiza enokutsha okanye eqhumayo, i-petroleum, okanye indawo yasemgodini, kufuneka iphathwe ngokungqongqo, kwaye kungcono ukuba ibephezulu kunokuba ibephantsi.Kucetyiswa ukuba usebenzise isithinteli-mlilo kuKlasi A, okanye isithinteli-mlilo esinedangatye esingenayo ihalogen esinedangatye eliphantsi kunye noDidi A olukwaziyo ukumelana nomlilo.
Zingaphi iintambo ezifakelweyo?
Inani leentambo lichaphazela inqanaba le-flame retardant yentambo.Ikakhulu isixa sezinto ezingezizo zetsimbi kwindawo enye emisela inqanaba le-flame retardant.
Xa ubala umthamo wezinto ezingezona zetsimbi zeengcingo kunye neentambo, ingcamango yendawo efanayo ibhekisela kumlilo wentambo xa ibamba umlilo.Okanye isithuba apho ubushushu bunokuphuma ngaphandle kokuthintelwa kwiingcingo neentambo ezikufutshane yaye bunokubutshisa.
Ngokomzekelo, kwii-trusses okanye iibhokisi zomkhombe ezineebhodi ezingenakuvutha umlilo ezizimeleyo enye kwenye, umjelo ofanayo kufuneka ubhekiselele kwibhulorho nganye okanye kwibhokisi yomkhombe.
Ukuba akukho nto yodwa yomlilo apha ngasentla, ngaphantsi okanye ngasekhohlo nasekunene, xa umlilo uchaphazela omnye nomnye, imiqulu yentambo yentsimbi engeyiyo eyentsimbi kufuneka ifakwe ngokufanayo ekubaleni.
Ubukhulu bekhebula
Emva kokuba umthamo wezinto ezingezizo zetsimbi kwintambo kwitshaneli efanayo inqunywe, ijonge ububanzi obungaphandle bekhebula, ukuba iintambo zincinci (ububanzi obungaphantsi kwe-20mm), udidi lwe-flame retardant kufuneka lujongwe ngokungqongqo.
Ngokuchasene noko, ukuba iintambo ubukhulu becala (ububanzi be-40mm okanye ngaphezulu), udidi lwe-flame retardant kufuneka luphathwe ngokungqongqo.
Isizathu sesokuba iintambo ezineedamitha zangaphandle ezincinci zifunxa ubushushu obuncinci kwaye kulula ukuzitshisa, ngelixa iintambo ezinobubanzi obukhulu bangaphandle zifunxa ubushushu obuninzi kwaye azifanelekanga ukuvutha.
Undoqo ekwenzeni umlilo kukuphemba.Ukuba uthe wabaswe kodwa akavuthi, umlilo uya kuwucima ngokwawo.Ukuba iyatsha kodwa ayicimi, iya kubangela intlekele.
Iintambo ezinqanda amadangatya kunye nezingenawo amadangatye akufuneki zixutywe kumjelo omnye
Amanqanaba okubuyiswa komlilo weingcingo kunye neentambo ezibekwe kumjelo ofanayo kufuneka zihambelane okanye zifane.Ilangatye elongeziweyo lezinga eliphantsi okanye elingenamlilo-intambo ezivuthayo ngumthombo womlilo wangaphandle kwiintambo eziphezulu.Ngeli xesha, nokuba iClass A retardant Cables nazo zinako ukubamba umlilo.
Ubunzulu bengozi yomlilo bumisela inqanaba lokubuyiswa komlilo wentambo
Kwiintambo ezisetyenziswa kwiiprojekthi ezinkulu zobunjineli, ezinjengeeyunithi ezingaphezulu kwe-30MW, izakhiwo ezinde kakhulu, iibhanki kunye namaziko emali, iindawo ezinkulu nezininzi ezixineneyo, njl. njl., inqanaba lokubuyiswa komlilo kufuneka libe phezulu kwaye libe ngqongqo phantsi kweemeko ezifanayo, kwaye kucetyiswa ukuba ukhethe intambo ephantsi yoMsi, i-halogen-free, ukumelana nomlilo kunye ne-flame-retardant cable.
Iintambo zombane kunye neentambo ezingengawo amandla kufuneka zibekwe zodwa enye kwenye
Ngokwentelekiso, iintambo zamandla kulula ukubamba umlilo kuba zishushu kwaye zinethuba lokuqhekeka kwesekethe emfutshane, ngelixa iintambo zolawulo kunye neentambo zolawulo lomqondiso zikwimo ebandayo ngenxa yombane ophantsi kunye nomthwalo omncinci, ngoko akukho lula ukuwenza. bamba umlilo.
Ngoko ke, kucetyiswa ukuba zifakwe ngokufanayo Izithuba ezimbini zibekwe ngokwahlukileyo, kunye nekhebula lamandla phezulu kunye nekhebula lokulawula phantsi.Ekubeni umlilo uhambela phezulu, iindlela zokwahlula umlilo zongezwa embindini ukuze kuthintelwe izinto ezitshisayo ukuba zingavuthuzi.
