机械开挖泥浆池
Mechanical excavation
1、机械伤人
Mechanical Injury
1、挖机进场工作前必须经OPMT,HSE验收合格后方可使用,土方开挖前施工区域搭设防护栏杆,每隔7M设置梯子,土方开挖按照1:1放,开挖遇到不明物体时,报告OPMT、HSE,经确认后方可开挖,采用人工开挖。
陈珉
2、泥浆池边人员坠落造成伤害
Injury from fell objected from border of excavation pit
设置临边围护,临边不许堆放材料。
Handrail shall be set around foundation pit
No piling at the border area of excavated pit
陈珉
3、土方塌方伤人
Injury from soil collapse
设警界区,无关人员严禁入内,挖机派专人指挥,到车转向,夜间没有红色警示灯
Safety lookout area shall be set around the excavating area, No permission no entering. Professorial director shall stand by during excavation
王文才
4、车辆伤人
Injury by vehicle
车辆行驶按OT现场行驶路线行驶,限速5公里/小时,
The routing & speed of Vehicle shall follow PMT HSE requirement, the maxim speed within 10KM per hour
张可同
5、土方乱堆造成伤人
Injury from unordered piling soil
土方按指定区域堆放、覆盖
Piling on marked area and covered during transporting
张可同
6.挖到电缆造成触电
Injury cause from touch up the U/G power cable during excavating
标示电缆位置,选择适当开挖方法,
Mark the location of U/G cable, select suitable excavation method
张可同
7 夜间开挖照明不足造成伤害
Not enough illumination during night excavation cause injury
在开挖区提供足够照明
Supply enough illumination on the excavation area

钻机钻孔施工
钻机进场安装调试,可能造成起重和电器事故
严格按钻机操作规程操作,防止钢丝绳过度弯曲磨损。
张可同
场地不平整,钻机行走中歪倒
对施工场地进行平整和压实
张可同

1、做好接零接地
2、有轮必有罩,有轴必有套
刘学斌
5
钢筋笼转运、接长等起重吊装作业
吊车选型错误,地基地耐力不够,没有安装力矩限位器造成吊车倾覆
1、吊车选型安全系数要足够
2、地基要进行压实,吊车支腿要有枕木等装置
3、吊车安装有吊重性能曲线表和安装力矩限位器
陈珉
吊车司机和起重工沟通不畅
吊车司机和起重工之间信号明确,并经过IET专门培训
陈珉
钢筋笼接长时起重伤害,插杠断裂
插杠选用安全系数足够,吊装时吊车随时待机。
陈珉
钢丝绳和卸扣等吊索具断裂
钢丝绳和卸扣安全系数足够,经常检查达不到要求及时更换。
陈珉
6
混凝土浇注
