土方开挖有哪些安全措施？ | 2012-4-9 9:50:00

土方开挖有哪些安全措施？

（1）在施工组织设计中，要有单项土方工程施工方案，对施工准备、开挖方法、放坡、排水、边坡支护应根据有关规范要求进行设计，边坡支护要有设计计算书。
（2）人工挖基坑时，操作人员之间要保持安全距离，一般大于2．5M；多台机械开挖，挖土机间距离应大于10m，挖土要自上而下，逐层进行，严禁先挖坡脚的危险作业。
（3）挖土方前对周围环境要认真检查，不能在危险岩石或建筑物下面进行作业。
（4）基坑开挖应严格按要求放坡，操作时应随坡的稳定情况，发现问题及时加固处理。
（5）机械挖土，多台阶同时开挖土方时，应验算边坡的稳定。根据规定和验算确定挖土机高边坡的安全距离。
（6）深基坑四周设防护栏杆，人员上下要有专用爬梯。
（7）运土道路的坡度、转弯半径要符合有关安全规定。
（8）爆破土方要遵守爆破作业安全有关规定。
