由于建筑施工高空中作业量大、作业时间长,再加上作业环境高且危险、条件恶劣,所以建筑施工高空坠落事件发生的就比较多,并且坠落死亡率和事件发生率所占的比重都较大,因此就必须彻查建筑施工产生高空坠落的原因。 Due to the large amount of work in high-altitude construction, long working hours, coupled with high and dangerous working conditions, the conditions are poor, so the construction of high altitude crashes occurred more often, and the proportion of both the death and mortality rates fall Therefore, it is necessary to thoroughly investigate the causes of the fall of buildings caused by high altitude.
