Njengoba ukuhlakanipha komphakathi kuya ngokuya kuthandwa, izintambo zesimanje zifana nesimiso sezinzwa somuntu, esidlulela kuwo wonke amagumbi esakhiwo.
Ngaso sonke isikhathi lapho wonke umuntu enza ubunjiniyela noma iphrojekthi, ucabanga kuphela: Mangaki amamodeli azosetshenziswa kule phrojekthi?Mangaki amamitha ekhebula okufanele asetshenziswe?
Kunamamodeli amaningi ocingo nekhebula, kodwa ukumelana kwawo nomlilo kanye nezidingo zokunqanda amalangabi akunakwa abantu, okube yingozi enkulu efihliwe yomlilo.
Ngakho-ke ungakhetha kanjani ukumelana nomlilo kanye nebanga lokubuyiswa komlilo lezintambo nezintambo kumklamo wobunjiniyela bephrojekthi?Lesi sihloko sinikeza iziphakamiso ezilandelayo zesithenjwa sakho:
Indawo yokubeka ikhebula
Indawo yokubeka ikhebula inquma ngokwezinga elikhulu amathuba okuba ikhebula lihlaselwe imithombo yomlilo yangaphandle kanye nethuba lokusha okulibazisekayo kanye nenhlekelele ngemva komlilo.
Isibonelo, izintambo ezingavimbeli zingasetshenziselwa ukungcwaba okuqondile noma amapayipi ahlukene (insimbi, i-asbestos, amapayipi kasimende).
Uma ikhebula libekwe ebhulohweni elivalwe kancane, i-trunking noma umsele wekhebula okhethekile (enesembozo), izidingo ze-flame retardant zingancishiswa ngokufanelekile yizinga elilodwa kuya kwamabili.Kunconywa ukusebenzisa i-Class C ye-flame retardant noma i-Flame Retardant Class D.
Ngenxa yokuthi mancane amathuba okuthi ihlaselwe yizinto zangaphandle kule ndawo, ngisho noma ibamba umlilo ngenxa yendawo encane futhi evalekile, kulula ukuzicisha futhi mancane amathuba okuba kubangele. a inhlekelele.
Ngokuphambene nalokho, izinga lokunqanda ilangabi kufanele likhuliswe ngokufanelekile uma umlilo uvezwa ngaphakathi endlini, uma igumbi likhuphuka ngesakhiwo, noma emhubheni oyimfihlo, i-mezzanine, noma umhubhe, lapho umkhondo womuntu nomlilo kutholakala kalula futhi isikhala sikhulu futhi umoya ungajikeleza kalula.Kunconywa ukuthi ukhethe isigaba B esibuyisela amalangabi ngisho nesigaba A se-flame retardant.
Uma indawo eshiwo ngenhla ingaphambili noma ngemuva kwesithando somlilo esishisa kakhulu noma isendaweni yamakhemikhali evutha umlilo noma eqhumayo, i-petroleum, noma indawo yasezimayini, kufanele isingathwe ngokuqinile, futhi kungcono ukuba ibe phezulu kunokuphansi.Kunconywa ukusebenzisa i-Class A retardant ye-flame, noma i-halogen-free-flame retardant ne-Class A ukumelana nomlilo.
Mangaki amakhebuli afakiwe?
Inani lezintambo lithinta izinga lekhebula elibushela umlilo.Ikakhulukazi inani lezinto ezingezona ezensimbi esikhaleni esifanayo elinquma izinga le-flame retardant.
Lapho kubalwa umthamo wezinto ezingezona ezensimbi zezintambo nezintambo, umqondo wesikhala esifanayo ubhekisela elangabini lekhebula lapho libamba umlilo.Noma indawo lapho ukushisa kungakhipha khona ngaphandle kwezihibe ezintanjeni nasezintanjeni eziseduze futhi kungabakhela.
Isibonelo, kuma-trusses noma amabhokisi omkhombe anamabhodi angashi aqhelelene, isiteshi esifanayo kufanele sibhekisele kubhuloho ngalinye noma ibhokisi lomkhombe.
Uma kungekho ukuhlukaniswa komlilo ngenhla, ngezansi noma kwesokunxele nakwesokudla, uma kwenzeka umlilo uthintana, amavolumu ekhebula engeyona eyensimbi kufanele afakwe ngokufanayo esibalweni.
Ukujiya kwekhebula
Ngemuva kokuthi umthamo wezinto ezingezona ezensimbi kukhebula esiteshini esifanayo kunqunywa, ubheka ububanzi obungaphandle bekhebula, uma izintambo zincane kakhulu (ububanzi obungaphansi kuka-20mm), isigaba sokubuyiswa komlilo kufanele kubhekwane naso ngokuqinile.
Ngokuphambene nalokho, uma izintambo zinkulu kakhulu (ububanzi obungu-40mm noma ngaphezulu), isigaba esibushela ilangabi kufanele siphathwe ngokuqinile.
Isizathu siwukuthi izintambo ezinobubanzi obuncane bangaphandle zimunca ukushisa okuncane futhi kulula ukuzibasela, kuyilapho izintambo ezinobubanzi obukhudlwana bangaphandle zimunca ukushisa okwengeziwe futhi azifanele ukuthungela.
Isihluthulelo sokwenza umlilo uwukubasela.Uma uvutha kodwa ungashi, umlilo uzozicima ngokwawo.Uma isha kodwa ingacimi, izodala inhlekelele.
Izintambo ezingabambezeli ilangabi nezingashisi amalangabi akufanele zixutshwe esiteshini esisodwa
Amaleveli angavimbeli ilangabi ezintambo namakhebuli abekwe esiteshini esifanayo kufanele ahambisane noma afane.Ilangabi elinwetshiwe lezintambo ezisezingeni eliphansi noma ezinganqamuki ilangabi liwumthombo womlilo wangaphandle wamakhebuli wezinga eliphezulu.Ngalesi sikhathi, ngisho noma amaCables e-Class A retardant flame nawo anamandla okubamba umlilo.
Ukujula kwengozi yomlilo kunquma izinga lokubuyiswa komlilo wekhebula
Ezintamboni ezisetshenziswa kumaphrojekthi amakhulu wobunjiniyela, njengamayunithi angaphezu kuka-30MW, amabhilidi amade kakhulu, amabhange nezikhungo zezimali, izindawo ezinkulu nezinkulu kakhulu eziminyene, njll., izinga lokubuyiswa komlilo kufanele libe phezulu futhi libe namandla ngaphansi kwezimo ezifanayo, futhi kunconywa ukuthi ukhethe ikhebula eliphansi Elingabhemi, elingenayo i-halogen, elikwazi ukumelana nomlilo kanye nekhebula elingashi.
Izintambo zikagesi nezintambo ezingezona amandla kufanele zibekwe zodwa
Uma kuqhathaniswa, izintambo zikagesi kulula ukubamba umlilo ngoba ziyashisa futhi zinethuba lokuphuka kwesiyingi esifushane, kuyilapho izintambo zokulawula kanye nezintambo zokulawula amasignali zisesimweni esibandayo ngenxa yamandla kagesi aphansi nomthwalo omncane, ngakho akulula ukuwenza. bamba umlilo.
Ngakho-ke, kunconywa ukuthi zifakwe okufanayo Izikhala ezimbili zibekwe ngokuhlukana, nekhebula lamandla phezulu kanye nekhebula lokulawula phansi.Njengoba umlilo uhambela phezulu, izindlela zokuhlukanisa umlilo zengezwa phakathi ukuze kuvinjwe izinto ezivuthayo ukuthi zingachaphazeli.
