1984年5月3日,杭州望湖饭店工地的一排高21米、长23米的十四层脚手架从上而下坍塌,造成十几名工人高空坠落,其中二人死亡,多人受伤。产生事故的主要原因是,随意在脚手架上堆放建筑材料、预制构件,随意拆除、更改或减少脚手架的支撑,擅自调换或超期使用绑扎材料等。 On May 3, 1984, a row of 21-meter-long, 23-meter-long 14-story scaffolding collapsed from the top down at the site of the Wang Hu Hotel in Hangzhou, causing more than a dozen workers to fall from a height. Two of them died and many were injured. The main cause of accidents is the random stacking of building materials and prefabricated components on scaffolds, and the dismantling, changing or reducing of scaffolding support, unauthorized use of lashing materials, etc.
