補水,貯存 10min的消防用水量,火災(zāi)發(fā)生時先由水箱供水滅火。 ④ 消防立管的直徑應(yīng)按室內(nèi)消防用水量由計算決定。同時建筑內(nèi)應(yīng)選用同一規(guī)格的消火栓、水帶和水槍,以方便使用。 ④ 水泵結(jié)合器應(yīng)設(shè)在消防車易于到達(dá)的地方,同時還應(yīng)考慮在其附近 15~40m范圍內(nèi)有供消防車取水的室外消火栓或貯水池。 消火栓口直徑 65mm,水帶 20m,水槍噴嘴口徑 19mm。加熱器采用導(dǎo)流型容積式加熱器。 ( 5)下列情況下應(yīng)設(shè)止回閥:水加熱器的冷水進(jìn)水管上、機械循環(huán)的回水管上、混合器的冷熱水供水管等處。 ( 6)膨脹管和膨脹罐 在開式熱水供應(yīng)系統(tǒng)應(yīng)設(shè)膨脹管。長期以來,我國采用的間接加熱設(shè)備主要是傳統(tǒng)的容積式加熱器。 熱媒與冷水不直接接觸,不污染加熱水質(zhì),冷凝水可重復(fù)利用,設(shè)備運行噪聲小。 商務(wù)大廈熱水用量大,對熱水供應(yīng)要求高, 客房要求 24 小時熱水供應(yīng),并要求熱水使用舒適方便,故 采用集中供熱的方式 。一般在建筑內(nèi)設(shè)專用鍋爐房或熱交換間,由加熱設(shè)備將水加熱后,供一幢或幾幢建筑使用。由于大廈六層最不利用水點到生活水箱最高水位為 。高區(qū) 6 層到 18 層,由地下室的生活水泵和屋頂?shù)纳钏渎?lián)合供水。 ( 7) 在技術(shù)層、吊頂層中給水管道、熱水管道、排水管道及電纜等交叉時,一般是電纜在上面,其次是給水管、熱水管、排水管。 給水埋地管道應(yīng)避免布置在可能受重物壓壞處。 ( 2) 引入管至少兩條,宜從建筑物不同側(cè)的兩條城市管道上接入,在室內(nèi) 將管道連成環(huán)狀或貫通狀雙向供水。我國設(shè)計規(guī)范推薦,分區(qū)最大靜壓值為 4~。 關(guān)鍵詞: 高層建筑, 綜合樓,給水排水,工程設(shè)計 ABSTRACT This engineering is about water and wastewater a high rise and multipleuse building, which lying on xi’an city. If presses its high demarcation, this building belong to high building , which meters. In the building, the 1st floor to the 5th floor are emporia, the 6th floor to the 11th floor are guesthouses and the 12th floor to the 18th floor are office. In the design, the main contents include the water supply system, hot water system, and the firefight system design with drain system which include the domestic waste water and the rainwater. In addition, the domestic water supply system is pumped by auto rhythm pump in vertical division block: It adopt in the hot water system concentration heat the way, machine circulating, the hydrant system and automatic fire extinguishing system are both secondary pressure boosting. Rainwater adoption the way that gravity inside drain ejects the house rainwater in time. Besides, the engineering includes district water and wastewater. For example, the designs for pump building and so on.
