【正文】 I 摘 要 根據題目要求 設計 了 17 層高層綜合 樓 的 建筑給水系統(tǒng)、 建筑 排水系統(tǒng)、 建筑 消防系統(tǒng)（消火栓給水系統(tǒng)及自動噴 水滅火 系統(tǒng)）、 建筑屋面 雨水排 水 系統(tǒng)設計。 給水系統(tǒng)采用分區(qū)供水，低區(qū) 負 一到三層，由市政管網直接供水 ；中區(qū) 四到十 一 層 ；高區(qū)十二到十七層。中區(qū)和高區(qū) 采用無負壓變頻供水 。 排水系統(tǒng)采用污、廢 水 合流制，底層單獨排 放 ，排水立管設伸頂通氣管，污水經化糞池處理后排向市政污水管網 。 消防系統(tǒng)分消火栓 給水 系統(tǒng)和自動噴水滅火系統(tǒng) 。屋面雨水排水系統(tǒng)采用檐溝內排水。 關鍵詞 ： 高層建筑 ； 給水系統(tǒng)；排水系統(tǒng)；消防系統(tǒng) II ABSTRACT Baised on the synthesis analysis, the water supply system, the drainage system, fire system(fire hydrant system and automatic sprinkler system) and roof drainage system for the level 17th high plex building are designed. The water supply system is applied by vertical division block. The floors from the negative to the third are the low areas, water of which is supplied directly by the municipal pipe work. The floors from the 4th to the 11th are the middle areas and the floors from the 12th to the 17th are the high areas,water of which are all supplied with the frequency conversion pump group. The drainage system is an interflow system of sewerage and waste water. Water of the first floor drains separately, the upright draining pipes are equipped with the ventilating pipes, and then the sewerage is disposed by the septic tanks and drains to the municipal waste pipe work. The fire system includes the fire hydrant system and automatic sprinkler system. The roof drainage system is an outside drainage system. Key Words: high building； water supply system； wastewater system； fire system III 目 錄 第一章 引言 .....................................................................................1 第二章 工程概況 及設計任務 ..........................................................2 設計題目 ..............................................................................................................................2 目的和作用 ..........................................................................................................................2 設計原始資料 ......................................................................................................................2 工程概述 ..............................................................................................................................3 第三章 建筑給水系統(tǒng) ......................................................................4 給水系統(tǒng)方案的確定 ..........................................................................................................4 水源情況 .......................................................................................................................4 用水量 ...........................................................................................................................4 分區(qū)和供水方式 ...........................................................................................................4 給水管材 .......................................................................................................................5 管網形式及敷設 ...........................................................................................................5 管道的水力計算 ..................................................................................................................6 生活貯水量計算 ................................................................................................................16 水表選型及水表水頭損失計算 ........................................................................................16 對室內管網所需水壓進行校核 ........................................................................................17 生活水泵的選擇 ................................................................................................................17 中區(qū)水泵的確定：（ 4~11 層） ..................................................................................18 高區(qū)水泵的選擇：（ 12~17 層） ................................................................................18 實驗室部分水泵選擇：（ 4~16 層） ..........................................................................19 生活水箱有效容積可按下式計算 ....................................................................................19 第四章 生活排水系統(tǒng)的有關計算 .................................................20 室內排水系統(tǒng)說明 ............................................................................................................20 排水體制 ............................................................................................................................20 管材及連接方式 ................................................................................................................21 IV 建筑排水水力計算 ............................................................................................................21 按經驗及有關規(guī)定確定某些排水管徑 ...................................................................21 按公式計算各污水管的管徑 ...................................................................................21 主通氣立管及結合通氣管管徑的確定 .....................................................................28 化糞池的設計 .............................................................................................................28 第五章 消火栓消防給水系統(tǒng)的計算 .............................................30 消防給水系統(tǒng)方案的確定 ................................................................................................30 室內消火栓給水系統(tǒng) ........................................................................................................30 消火栓的布置 .............................................................................................................30 消火栓口所需的水壓 .................................................................................................31 校核 .............................................................................................................................32 水力計算 .....................................................................................................................33 其他設施的設計 ................................
