2016—2020年建筑塔式起重机事故统计分析

Statistical analysis of tower crane accidents form 2016 to 2020

为探索我国建筑塔式起重机事故发生规律,采取条形图、柱状图及其他图表等方法对2016—2020年塔式起重机事故进行统计与分析,选取事故方式与原因的分布规律作为数据。通过"2-4"模型对每个事故的原因进行分析,找出近年来发生事故的规律有:塔吊作业过程中发生的事故数占事故总数一半以上;员工安全意识淡薄占70%以上;安全理念不足的越多,事故越容易发生。通过对塔式起重机事故发生规律的研究,为安全管理系统提供准确的保障。

In order to explore the law of the occurrence of construction tower crane accidents in China, methods such as bar graphs, column graphs and charts are used to conduct statistics and analysis the accidents from 2016 to 2020, and the distribution law of accident methods and causes are selected as data.The cause and mode of each accident are analyzed by "2-4" model.The law of accidents in recent years are as follows: ore than half of the accidents occurred during tower crane operation;over 70% of employees have weak safety awareness;the more the safety concept is insufficient, the easier it is for accidents to occur.Accurate guarantee can be provided for safety management system through the research of tower crane accident occurrence.
