5. 消防水箱設置的其他要求

5.1 xiaofangyongshuiyuqitayongshuihebingdeshuixiang,yingyouxiaofangyongshuibuzuotayongdejishucuoshi。

5.2 發生火災后,由消防水泵供給的消防用水,不應進入消防水箱,應在消防水箱的出水管上設
置止回閥。

5.3 xiaofangshuixiangyiyongshenghuo、shengchangeishuiguandaochongshui。

5.4 高層建筑物內的消防水箱宜采用兩個,在一個水箱檢修時,仍可保存必要的消防應急用水,
并應在水箱的底部用聯絡管連接,聯絡管上設置閥門,此閥處于常開狀態。

5.5 消防水箱宜與其他用水的水箱合用,使水箱內的水經常處于流動更新狀態,以防水質變壞,
其他用水可采用虹吸管頂鉆眼等措施供給。

5.6 xiaofangshuixiangdefujianpeizhijixiaofangshuixianganzhuang、buzhikecanzhaoyibangeishuishuixiang,zaicibuzailiewenshuoming。

6. 消防水箱的材質選擇

目前適合做水箱的材料有許多種,最常見的材料有鋼板、不銹鋼、鋼筋混凝土、玻璃鋼、搪瓷鋼
板等材料,但它們各有優缺點。

6.1 tansugangbanhanjieerchengdegangbanshuixiang,neibiaomianxujinxingfangfuchuli,bingqiefangfucailiaobudeyouaiweishengyaoqiu。

6.2 鋼筋混凝土現場灌注的水箱,重量大,施工周期長,與配管邊接處易漏水,清洗時表面材料易
脫落。

6.3 搪瓷鋼板水箱水質不受污染,能防止鋼板銹蝕,安裝方便迅速,不受土建進度的限制,結構
合理,堅固美觀,不變形不漏水,適用性廣。

6.4 玻璃鋼水箱不受建筑空間限制,適應性強,重量輕,無銹蝕,不滲漏,外形美觀,使用壽命
短,保溫性能好,安全可靠,安裝方便,清洗維修簡單。

6.5 不銹鋼水箱堅固,不污染水質,耐腐蝕、不漏水,清洗方便,重量輕,不滋生藻類,容易保
溫,美觀,施工方便,但價格高。
