我用自己的亲身经历想对大家说:空顶作业险!记得8年前的一个早班,我作为一个班长,带着三个大工在上山开门。开门处有底板,抬开门栌时,已打好了三个支柱,撑筒也打好了三个,第四个支柱是其中一个大工黄师傅打的,因为有底板,支柱又有点弯,这个支柱他没打紧,我说不行,但他说可以。 I use my own personal experience to say to everyone: Topped Insurance! Remember an early morning 8 years ago, I as a squad leader, with three great work in the mountains to open the door. Open the door at the bottom plate, lift the door 栌, the three pillars have been laid, the cylinder also lay three, the fourth pillar is one of the Big Yellow master play, because the floor, the pillars have a little bend, this He did not tighten the pillars, I said no, but he said yes.
