Ulwakhiwo lweProjekthi yeSithuba seSithuba seSithuba seemitha ezili-126 seSiziko soMbane seSithuba seSithuba seNsimbi
Le projekthi yindawo yesakhelo sesetyhula yemizi-mveliso / ubude beemitha ezingama-55 / ubude bubonke buziimitha ezingama-900 / ubude bubonke bungama-65 eemitha.
1. Zombini iziphelo zazo zonke iipayipi zetsimbi kufuneka zivaliwe, kwaye iipleyiti zokutywina kufuneka zifakwe ngaphambi kokuba zivaliwe ukukhusela ukubola kwimibhobho.
2. Amacandelo agqityiweyo kufuneka anikwe amandla ngokususa i-rust, ukwenzela ukuba ubuso bentsimbi buveze umbala wensimbi, ibakala lokususa i-rust alikho ngaphantsi kwe-Sa2.5, kwaye umgangatho wokususa umhlwa kufuneka uhlangabezane neemfuno ezifanelekileyo ze-GB8923.
3. Emva kokuba intsimbi ichithekile, iingubo ezimbini ze-80μm epoxy zinc-rich primer, enye i-70μm epoxy micaceous iron intermediate paint, kunye nepeyinti yomlilo ifakwe.Umgangatho wokumelana nomlilo wale projekthi mbini, i-coat non-intumescent fireproof yi-25mm, kwaye ixesha lokumelana nomlilo liyi-1.5h.Iingubo ezivuthayo zomlilo kufuneka zibe nengxelo yokuvavanya kunye nelayisenisi yokuvelisa evunyiweyo yi-arhente yelizwe lokuvavanya ukuchasana nomlilo.Umgangatho kunye nokwakhiwa kweengubo zokucima umlilo ezisetyenzisiweyo ziya kuhlangabezana neemfuno ze "IiNkcazo zezoBugcisa zoKhuseleko loMlilo lweZakhiwo zeSimbi" (CECS200: 2006) kunye ne "Fireproof Coatings for Steel Structures" (GB14907-2002).
4. Amalungu esakhiwo kufuneka agcinwe rhoqo.Ngaphakathi kobomi benkonzo yoyilo lwesakhiwo esiphambili, umjikelo wokugcinwa kwengubo yomgangatho wezinto zentsimbi ezichongiweyo ngobuchule kwaye zivunyiwe ukuba zisetyenziswe akufanele zibe zide kunobomi benkonzo yegama leemveliso ezisetyenzisiweyo;Iifilimu zepeyinti ezonakalisiweyo zamacandelo esakhiwo kufuneka zipeyintwe kwakhona ngexesha.
5. Xa isakhelo segridi sigcinwe ngeenxa zonke, kufuneka sidibaniswe nesakhiwo sokuqala ukulinganisa amandla anqamlekileyo.
