某地铁站消防给排水系统设计
某地铁站消防给排水系统设计(论文11000字)
摘要
在城市规划日渐完善，城市交通越来越拥堵的的今天，地铁成为了很多人日常出行的第一选择。地铁站内具有显著的人流量大、人均空间不足等特点，在发生火情的时候，地面消防救援力量难以进入实施救援。在这种情况下地铁站消防给排水系统以及设施就显得极为重要和珍贵。
近期以来，江苏省火灾事故频发，商场、施工建筑、化工厂等各种场所均发生过火情。国家对消防也日益重视的今天，我们把目光放在了地铁站，重点规划了地铁车站消防排水系统的设计以及各设施的选择的计算过程。设计步骤如下：首先根据地铁站的特点，按照国标要求，划分出合理的防火区，将站厅层划分为4个防火分区，站台层划分为3个防火分区；选择栓口直径65mm、喷嘴直径19mm、水带长度25m的室内消火栓，确定室内消防用水量为15L/s，选择型号为80DL50-202的水泵，计算得消防水池容积114m³，选用型号为 SS100的室外消火栓，确定室外消防用水量为30L/s，接型号为SQS150-1.6的水泵接合器，使用天正给排水和CAD软件绘制平面图和相关系统图。本设计具有一定的科学性和可行性。

Design of fire water supply and drainage system in a subway station
Abstract
With the improvement of urban planning and the increasingly congested urban traffic, subway has become the first choice for many people to travel everyday. The subway station has obvious characteristics such as large traffic and insufficient space per capita. In case of fire, it is difficult for ground fire rescue forces to enter the implementation of rescue. In that case, the fire water supply and drainage system is extremely important, and the preciousand facilities of the subway station is also important too.
Recently, fire accidents have occurred frequently in Jiangsu Province, and fires have occurred in various places such as shopping malls, construction buildings, and chemical plants. Today, the country is paying more and more attention to fire protection. We have set our sights on the subway station, focusing on the design of the fire-fighting drainage system of the subway station and the calculation process of the selection of each facility. The design steps are as follows: Firstly, according to the characteristics of the subway station, according to the requirements of the national standard, a reasonable fire zone is divided, and the station floor is divided into four fire zones. The platform is divided into three fire zones; the diameter of the plug is 65mm and the diameter of the nozzle is selected. 19mm, indoor fire hydrant with a length of 25m, determine the indoor fire water consumption is 15L / s, select the model 80DL50-202 of the pump, calculate the fire pool volume 114m3, select the outdoor fire hydrant model SS100, determine the outdoor fire water consumption is 30L / s Connect the water pump adapter of model SQS150-1.6 and draw the floor plan and related system diagram using Tianzheng Water Supply and Drainage and CAD software. This design has certain scientific and feasibility.
