摘 要

本工程为一幢主楼为十九层的一类高层办公综合楼，地下一层为设备用房，地面一层至十九层为办公室。设计内容有给水系统、排水系统、雨水系统、消火栓和自动喷淋消防系统等。其中，室内给水系统分成三个区，地面一至五层为市政区，由市政管网直接供应，六至十二层为加压一区，十三至十九层为加压二区。分区方式采用并联分区，加压方式采用变频给水设备加压；室内排水系统采用污废合流、雨污分流排水体制；根据计算，室内消火栓系统不分区，消火栓由消防泵加压供水；根据《建筑设计防火规范》，本工程地下一层及地面十九层均应设置室内自动喷水灭火系统，办公室火灾危险等级为中危Ⅰ级，按吊顶考虑，安装下垂型喷头，地下设备用房火灾危险等级为中危Ⅱ级，按不吊顶考虑，安装直立型喷头，均采用湿式自动喷水灭火系统；在机房屋面设15T高位消防水池，供消火栓系统和自动喷水灭火系统初期火灾灭火，消火栓系统在屋面增设稳压设施，在地下室设350T消防水池，供室内消火栓系统3小时灭火用水量和室内自动喷水灭火系统1小时灭火用水量，由《建筑给水及消火栓系统技术规范》，本工程消火栓系统和自动喷水灭火系统均应设置稳压设施，本设计在屋面分别设置了消火栓系统稳压泵及自动喷水灭火系统稳压泵。

Abstract:

This project is a main building is a high-rise comprehensive building nineteen floor office, an underground equipment room, ground floor level to the nineteen office. Design contents of water supply system, drainage system, drainage system, fire hydrant and automatic fire sprinkler systems. Among them, the indoor water supply system is divided into three areas the ground, one to five for the municipal district, supplied directly by the municipal pipe network, six to twelve plus one district, thirteen to nineteen for the two pressure area. Using parallel partition partition, pressurized by pressurized water supply equipment; indoor drainage system using sewage confluence of rain sewage diversion drainage system;According to the calculation, the indoor fire hydrant system is not partitioned, and the hydrant is pressurized by a fire pump; according to the code for fire protection design of buildings ", this project underground and ground nineteen the layer should be set up indoor fire sprinkler system, office fire risk level risk grade, according to the ceiling, drooping sprinkler installation, underground equipment room fire danger level is in danger of grade II, is considered as not the ceiling, installed upright sprinkler, adopt wet sprinkler system15T high fire pool should be installed on the roof of engine room, fire hydrant system and automatic sprinkler system fire hydrant system early, additional regulated facilities on the roof, In the basement, set up 350T fire pool for indoor fire hydrant system 3 hours fire water consumption and indoor automatic sprinkler system 1 hours extinguishing water consumption,By "building water supply and fire hydrant system technical specification gt; system should be set up regulated facilities for the project of fire hydrant system and automatic sprinkler, the design of the roof were set up fire hydrant system and automatic sprinkler system pump pump.

Key words: building; water supply; drainage; fire hydrant; automatic sprinkler
