洞口防护有几种类型？ | 2012-4-5 10:46:00

洞口防护有几种类型？

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。
