洞口防护的几种类型 | 2012-3-28 16:17:00
洞口防护的几种类型
洞口作业的防护措施,主要有设置防护栏杆、栅门、格栅、阻挡件和用遮盖物盖设,以及架设安全网等多种方式。
不同情况下的防护设施,主要有以下几类:
(1)各种板和墙的洞口,按其大小和性质分别设置牢固的盖板、防护栏杆、安全网或其它防坠落的防护设施。
(2)电梯井口,视具体情况设防护栏杆和固定栅门或工具式栅门,电梯井内每隔两层或最多隔10m就应设一道安全平网。也可以按当地习惯,设固定的格栅或砌筑矮墙等。
(3)钢管桩、钻孔桩等桩孔上口,柱型、条型等基础上口,未填土的坑、槽口,以有人孔、天窗、地板门和化粪池等处,都要作为洞口而设置稳固的盖件。
(4)施工现场与场地通道附近的各类洞口与深度在2m以上的敞口等处除设置防护设施与安全标志外,夜间还要挂灯示警。
