1、前言本工程是杭州市云舒大廈消防給排水設計,云舒大廈總高為73m,屬于一類高層建筑。該大廈是集賓館、餐飲中心、辦公、綜合市場等于一體的綜合性建筑。云舒大廈可分為標準層、裙房和地下室,本次設計根據(jù)要求完成云舒大廈的消防系統(tǒng)和裙房給排水設計。其中消防系統(tǒng)包括消火栓系統(tǒng)和自動噴灑系統(tǒng)。本次工程中消防系統(tǒng)和給水系統(tǒng)分開設置,消火栓系統(tǒng)與自動噴灑系統(tǒng)共同設計。根據(jù)規(guī)范要求消火栓系統(tǒng)分一個區(qū);自動噴灑系統(tǒng)分區(qū)要求不能超過50m。消火栓系統(tǒng)要保證兩股水柱能到達任何位置,整個消防系統(tǒng)要保證三個水源(消防水池、消防水箱、水泵接合器)。消火栓系統(tǒng)流量4
2、1.9L/s,選用3套水泵接合器,2臺消防泵一用一備。自動噴灑系統(tǒng)分為2個區(qū),低區(qū)(地下一層至四層)和高區(qū)(五層至十七層)。自噴系統(tǒng)流量高低區(qū)均為23.94L/s,故均設置2套是泵接合器。消火栓系統(tǒng)和自噴系統(tǒng)合用一套增壓設備,包括2臺增壓泵和一個氣壓罐。高區(qū)分4個報警閥組,低區(qū)2個報警閥組。給排水做裙房,包括了餐廳,商場等多種場合用水,選用水箱加水泵的給水方式??偨o水流量為3.97L/s,設置2臺給水泵互為備用,生活水箱大小為30m3。關(guān)鍵詞消防系統(tǒng)給水系統(tǒng)排水系統(tǒng)設計-84-PrefaceThisprojectisthedesi
