摘 要

大型商场由于人员密集、可燃物多、电气线路庞杂，火灾危险性大且爆发火

灾后人员疏散的难度大，容易造成群死群伤的严重后果，在首倡尊重生命、以人

为本的今天，确保大型商场在火灾时人员能够安全撤离这点很重要，本设计主要从安全角度对某商场进行给水系统设计，本设计主要采用两种灭火系统——自动喷水灭火系统和室内消火栓系统。

在进行消火栓设计时，主要围绕室内消火栓的类型、组成、设置原则以及设备的布置和消防用水量的计算等展开。通过全面的思考与计算，选取适当的消火栓型号、确定系统供水管径，以及水枪、水带的型号。

在自动喷水灭火系统部分主要介绍了湿式系统的设置原则、类型、构成、设备以及布置要求和用水量等。通过查找相关文献，分析工程图纸，确定喷头的选型、支管管径的选择。自动喷水灭火系统具备结构简单、易操作、施工工艺方便、出水快、投资少、费用低、范围广、灭火效果好等优点。这种灭火系统占据整个自动喷水灭火系统的75%以上，适合用于常年温度在4—70℃范围内的能用水灭火的建筑物中。

Design of Water Extinguishing System for a Shopping Center

ABSTRACT

Large shopping malls due to staff-intensive, rich products, many electrical lines, fire risk and fireEvacuation of personnel after the difficulty of evacuation, likely to cause the serious consequences of group death,In advocating respect for life, people

Based on today, how to ensure that large-scale shopping malls when the fire evacuation of personnel in the architectural design is particularly important，This design mainly from the security point of view of a shopping mall water supply system design， this design mainly uses two kinds of fire system, sprinkler fire extinguishing system and indoor fire system.

In the design of the fire hydrant, mainly around the types of indoor fire hydrant, composition, setting principles and equipment layout and fire expanded in the calculation of the amount of water. Through comprehensive consideration and calculation, select appropriate fire hydrant types, determine the system of water supply pipe diameter, and hoses, hose model, and determine the setting of fire water tank and water tank.

In the automatic water spraying fire extinguishing system, the principle, type, structure, equipment, arrangement and water consumption of the system are introduced.reading engineering drawings, determining the nozzle selection, pipe diameter selection. Automatic water spray extinguishing system has the advantages of simple structure, convenient construction and maintenance management, timely fire extinguishing, immediate water outlet, less construction investment, low management cost and wide application range. Accounted for more than seventy-five percent of the entire automatic sprinkler system, suitable for installation in the annual temperature in the range of 70 to 4 C can be the use of water to fire buildings, buildings.
