挖土方作业安全须知 | 2011-7-27 14:08:00

1、挖掘土方时，两人操作间距不少于3m，应由上而下逐层挖掘，禁止采用掏洞或边脚掏挖上部崩塌的方法操作。

2、在较深的地坑、地槽及井内工作时，应经常进行有毒气体的测定，发现有毒气体应立即停止作业，采取可靠的措施后，方可恢复工作。

3、在建筑物、电杆、铁塔、铁路、架空管道支架等附近挖土时，应根据作业方案进行加固或采取防护措施，否则不准挖土。

4、在公路或公共场所附近挖土，应在施工区域四周设置围栏和警告标志，晚间应有灯光信号。

5、离地坑、地槽边缘0.8m以内，不得放置土方及材料，沟槽边0.5m以外，土方堆置高度不得超过1.5m。

6、挖土前必须排除积水，和检查槽帮有无裂缝，防止塌陷。

7、发现土方边坡有裂缝，有垮塌危险时，必须暂停施工。
