苗族、侗族木质结构建筑物火灾调查新思路初探

Preliminary study on fire investigation of wooden buildings of Hmong and Dong ethnicity

苗族、侗族主要居住在我国贵州省的黔东南、黔南、铜仁等多个地区,其住宅多是木质结构房屋且通常建筑密度较大,由于此类建筑结构通常耐火等级低、火灾荷载高且无有效的防火分隔设施,一旦发生火灾短时间内即可导致“火烧连营”事故的发生,处置过程中稍有不慎即可引发大面积火灾事故。由于此类建筑发生火灾后通常具有过火面积大、坍塌损毁严重、引火源种类特殊等特点,给事故发生后的火灾调查工作增加了一定的难度。现对苗族、侗族木质结构建筑物火灾特点进行逐一分析,从该类火灾事故的调查难点入手,对该类火灾的调查方法进行具体优化,并结合实际提出改进该类火灾调查工作效果的新思路。

Hmong and Dong ethnicity mainly live in Qiandongnan,Qiannan,Tongren and other areas in Guizhou Province.The houses are mostly wooden structures,and they are usually densely built.Such buildings usually have low fire resistance classification,high fire load and no effective fire separation facilities.Once a fire occurs,it can lead to a series of accidents in a short time,and a small amount of carelessness in the disposal process can cause a large fire accident.Since such buildings usually have the characteristics of large fire areas,serious collapse and damage,and special types of ignition sources after fire,it adds a certain degree of difficulty to the fire investigation after the accident.Now the fire characteristics of wooden buildings of Hmong and Dong ethnicity are analyzed one by one.Starting from the difficulties in investigation of the fire accident,the investigation method of the fire is specifically optimized.Combined with the current situation,a new idea to improve the effect of fire investigation is put forward.
