Outdoor pipe network pressure can not take into account the form of a regional water supply water pressure requirements, domestic water supply system to meet the most negative point. 16 layer directly by the municipal pipe network water supply 612 layer by the pool pumps tank joint water supply, unified by the residential property construction. Both to ensure the highwater supply security, and of using the external network owned pressure, operating cost savings.Fire water system partition, unified by the district water supply. Hydrant arranged to ensure that the two jets of water to reach room.The drainage system uses the sewage waste diversion system, in order to facilitate the running of the subsequent water reuse facilities. Dedicated ventilation system settings riser and stretch top snorkel, to guarantee the balance of air pressure in the tube, to prevent the water seal damage. On the first floor, the second floor is a separate drainage effectively prevent the 312 floor drainage on the first floor, households.Key words: Building water supply and sewage project sewerage systemsthe drinking water supply system fire water supply system目 錄第一章 概述 1 設(shè)計任務(wù) 1 1 1 1 2第二章 方案比選及說明 3 3 3 5 5 6 6 6 6 7 7 7 7 7 管道布置 8第三章 設(shè)計計算 9 9 9 9 9 11 11 低區(qū)(16層)水力計算 12(612層)水力計算 16: 17 18 18 19 20 22 22 23 23 23 24第四章 經(jīng)濟(jì)分析 28參考資料 30致謝 32第一章 概述 設(shè)計任務(wù)根據(jù)城市花園6樓建筑、結(jié)構(gòu)條件圖,進(jìn)行該建筑室內(nèi)給排水工程設(shè)計。消防給水系統(tǒng)不分區(qū),由小區(qū)統(tǒng)一供水。第二章 方案比選及說明給水方式是建筑內(nèi)部給水系統(tǒng)的供水方案,合理的供水方案應(yīng)綜合考慮技術(shù)因素和經(jīng)濟(jì)因素兩個方面。建筑生活給水系統(tǒng)由引入管、給水管道、給水附件、給水設(shè)備、配水設(shè)施和計量儀表組成。根據(jù)高層民用建筑設(shè)計防火規(guī)范(GB50045952001年修訂版)要求,超過七層的單元式住宅應(yīng)設(shè)置消火栓給水系統(tǒng)。室內(nèi)消防設(shè)置兩條引入管,立管設(shè)置于電梯間內(nèi),豎向成環(huán),橫干管分別設(shè)置在屋頂和地下。 管道布置排水管道的布置敷設(shè)在保證排水暢通安全可靠的前提下,還應(yīng)兼顧經(jīng)濟(jì)、施工、管理、美觀等因素。,其沿程水頭損hy==。本設(shè)計中,19mm的水槍配65mm的襯膠水帶。冷凝管采用經(jīng)驗(yàn)法,管徑為75.第四章 經(jīng)濟(jì)分析為有計劃地使用資金,本節(jié)作簡要的經(jīng)濟(jì)分析,根據(jù)設(shè)計圖紙計算工程量,套用《全國統(tǒng)一安裝工程預(yù)算定額》第八冊給排水、采暖、燃?xì)夤こ?(GYD2082000),單位工程費(fèi)詳見表442。=+=,查水塑料管水力計算表,且連有大便器,選用DN為110的塑料排水管。=25+=23 m(單排雙股)采用下式計算:S 37式中 S —— 消火栓間距,m; R —— 消火栓保護(hù)半徑,m; b —— 消火栓最大保護(hù)寬度,m。 時變化系數(shù)。為保
