摘 要

建筑给水竖向分三个区，低区：四层及以下由市政给水管直接供水；中区：五层至十层由设于地下室的变频调速水泵一供水；高区：十一层及以上由设于地下室的变频调速水泵一供水。中区，高区共用水泵，中区管道在泵后设减压稳压设备。建筑室内排水采用生活污废合流制，通气管采用专用通气立管通气。排水横管隔层安装在吊顶之下，接至排水立管，一层污废水单独排水出户。电梯排水经排水沟汇集排至集水井，经潜污泵提升至检查井。屋面雨水排水系统则采用内排水系统，重力流排水，屋面雨水经天沟收集，通过雨水斗、雨水立管排至室外雨水检查井。

本工程为17层、建筑总高度65.40 m，高级高层商务酒店，耐火等级不低于一级。室内消防给水系统均采用临时高压系统。在地下室设置消防加压泵房、消防蓄水池，在本建筑天面设高位消防水箱。室内消火栓用水量Q=40L/s，火灾延续时间3小时，一次灭火用水量270m³。共设2台消火栓给水加压泵，一用一备，设二根出水管，接至环状给水管网。室内消防给水管道布置成环状，按消防规范的要求设置室内消火栓，保证同层任何部位有两个消火栓的水枪充实水柱同时到达。平时由高位消防水箱和气压设备保证系统水压，消火栓给水加压泵由设在各个消火栓箱内的消防泵启泵按钮或消防控制中心直接开启。室外设置两套消防水泵接合器，供消防车向室内消火栓给水管网补水。

自动喷水系统平时由高位消防水箱保证系统水压。火灾发生后，喷头动作后水流指示器的信号及湿式报警阀的压力开关信号传至消防控制中心，消防控制中心自动开启自动喷水灭火系统给水加压泵向管网供水。室外设置两套消防水泵接合器，供消防车向室内自动喷水灭火系统管网补水。

Design of water supply and drainage engineering for Hui Tong Mansion

ABSTRACT

The design of Hui tong building water supply and drainage design, including the living water system, fire hydrant system, automatic sprinkler system, drainage system and roof rainwater drainage system of five systems

Building the vertical water supply is divided into three areas, low area: four and below by the municipal water supply water supply; central: five to ten layers by variable speed pump in the basement of a water supply; high: level eleven and above by variable speed pump in the basement of a water supply.The central area, common water pump, central pipeline equipment in the pump after decompression.The indoor drainage of the building is made of living sewage and waste combined system, and the ventilation pipe is ventilated by special ventilating standpipe. The drainage horizontal pipe is installed below the suspended ceiling and connected to the drainage standpipe, and a layer of waste water is drained out of the drain separately. The elevator is drained and discharged to the collecting well through the drainage ditch, and is raised to the inspection well by submersible sewage pump. Roof rainwater drainage system adopts internal drainage system, gravity drainage, roof rainwater collected by gutters, through the rain, rain water pipe line to outdoor rainwater inspection wells.

This project is 17 floors, with a total height of 65.40 m, and the highest level of Traders Hotel is not less than one grade. The indoor fire water supply system adopts temporary high voltage system. A fire pressure pump house and a fire protection reservoir are arranged in the basement, and a high fire water tank is arranged on the day surface of the building. Indoor fire hydrant water Q=40L/s, fire duration 3 hours, a fire with water 270m. A total of 2 fire hydrant feed water pressure pump, one with a standby, set up two outlet pipe, and then connected to the ring water supply network. The indoor fire water supply pipe is arranged in a circle, and the hydrant is set up according to the requirements of the fire code, and the water gun with two fire hydrants at any part of the same layer is guaranteed to reach the water column at the same time. Usually by the high fire water tank and air pressure equipment to ensure system water pressure, fire hydrant feed water pressure pump from the fire hydrant pump in each box, pump button or fire control center directly open. The outdoor set up two sets of fire pump adapter for fire engines to the indoor fire hydrant water supply.

Automatic sprinkler system usually by high fire water tank to ensure system water pressure. After the fire, after the nozzle moves signal and wet flow indicator alarm pressure switch valve signal to the fire control center, automatic opening pressure pump to the water supply pipe network automatic sprinkler system water fire control center. The outdoor set up two sets of fire pump adapter for fire trucks to indoor fire sprinkler system water supply pipe network.

Keywords:Water supply systems; drainage systems; fire hydrant systems;sprinkler systems storm water systems.
