建设工地沥青拌和站遭受雷击的影响因素分析

The impact factor analysis on construction site asphalt mixing stations was analyzed

建设工程施工现场,布置着大量的临时生产设备,因为其使用时间短,防雷安全往往不被人们所重视,因此经常导致雷击事故的发生,造成人民生命财产的损失。以漳州滨海大通道某建设工地临时沥青拌和站遭受雷击损失惨重为例,通过现场勘测,找出其遭雷击原因,结合其所处地理环境、土壤结构、气候特点,提出其经济合理的防雷整改设计方案:直击雷防护(接闪器、引下线、接地装置)、闪电感应防护、接触电压防护、跨步电压防护等设计。通过一系列防雷工程整改后,防雷工程运行良好,周边再发生雷暴,沥青拌和站都完好无损。

Construction engineering construction size,place a large number of temporary production equipment,just because of the using time iso short,while the project ends,then its mission end too. Lightning projection safety are often not taken seriously by many people,so often lead to lightning accident happen,taking people＇s life and property losses accordingly. This paper,taking a construction site temporary Zhangzhou Costal thoroughfare asphalt mixing station lightning strike heavy loss,for example,Through the field survey,and find out the lightning strike reason,combined with its geographical enviroment,climate,soil structure characteristics,puts forward the econimic and reasonable rectification of lightning protection design scheme： Such as lightning protection（ Air-termination system,Down-conductor system,Earth-termination system）,Lightning induction Protection. Touch Voltage Protection. Step Voltage Protection. etc. Lightning strike,asphalt mixing station running well.
