地下车库及配电室上灭火设计设计.docVIP

河南理工大学本科毕业设计 PAGE LVIII 毕业设计 某地下车库及配电室灭火设计 摘要：近些年来，随着人们生活水平的提高，我国汽车使用者的数量增长迅猛。但是由于城市用地紧张，现有汽车库远远不能满足停车要求，地下汽车库成为解决这一问题的主要途径之一。地下建筑一般是半封闭或全封闭的结构，一旦发生火灾，将产生大量的热量和烟气，且很难排出，更严重的是这些烟气毒性大，对人员进行疏散非常困难，极易造成人员伤亡和财产损失，对社会造成严重的危害。因此，对其进行合理的消防设计具有重要的意义。配电室与车库同在一层，由于电气火灾的特殊性，也有必要对其进行单独的灭火设计。 本次设计针对地下车库结构的特殊性和火灾发生发展的特殊规律，借鉴国内外高层建筑地下车库的成功设计经验，结合国家颁布的各项相关消防法律法规，对地下车库进行比较全面的消防设计。此次消防设计涉及到四个方面：结构防火设计、消火栓及自动喷水灭火系统的设计、配电室灭火设计。本设计的目的是通过全面的防火设计，来提高扑救地下车库初期火灾的成功率，减少该地下车库的火灾隐患和火灾发生时造成的损失，确保人生和财产安全。 关键词：地下车库 消火栓系统 自动喷水灭火系统 配电室 The fire-extinguishing design for an underground garage and distribution room Abstract: In recent years, the number of car in China grows rapidly as peoples living standards improves.However, due to the shortage of land, the existing parking garage can not meet the requirement, the underground garage become the main way to solve this problem. Underground construction is generally semi-enclosed or fully enclosed structure, the garage will generate a lot of heat and smoke if it fires, and is difficult to discharge, more serious thing is that these toxic fumes is very difficult to evacuate person,the heat and smoke can easily result in casualties and property losses, causing serious harm to society. Therefore, it is significant to design reasonable fire safety design. The distribution room and the garage are in the same layer, and the distribution room has the particularity of electrical fire, so it is necessary to design a separate fire design. The design is aimed at doing a relatively overall fire protection design for an underground garage, according to the unique structure of the underground garage, the special development laws of fire, and the successfully designed experiences of the underground garage in home and abroad and all the relevant fire control laws and regulations. This design involves four aspects: design for fire protection of construction, hydrant system, sprinkler system and design for fire protection of distribution room. The design’s purpose is
