问题 问答题 案例分析题

某城市跨线立交桥工程,桥梁全长811m,共计24跨,桥梁下部结构有220根1.5m的钻孔灌注桩,采用反循环钻机成孔。项目部针对钻孔桩数量多,经招标程序将钻孔作业分项工程分包给甲机械施工公司,由甲公司负责组织钻孔机械进行钻孔作业。施工过程中现场发生如下事件:

事件1:因地下管线改移困难,经设计单位现场决定10、11、12轴原桩位移动并增加钻孔桩数量,立即办理了洽商变更手续。项目部及时复印后,直接交给测量员和负责本段施工的工长。

事件2:项目部在现场文明施工检查中发现原有泥浆沉淀池已淤积,正在进行钻孔施工的泥浆水沿排水沟流到工地附近的河道里,现场土堆旁有未燃尽的油毡碎片。

事件3:甲公司液压起重机起吊钢筋笼时,因钢筋笼的U形吊环与主筋焊接不牢,起吊过程中钢筋笼倾倒,作业人员及时避开,但将泥浆搅拌棚砸坏。项目经理组织人员清理现场,并开展事故调查分析,对分包方进行罚款处理,调查报告完成后,经项目经理签字,上报了企业负责安全的部门。

事件4:受钻孔机械故障影响,项目部要求甲公司增加钻孔机械,以保障钻孔作业计划进度。因甲公司钻机在其他工地,需等5d后才能运到现场,等到该桥全部钻孔桩完成时已拖延工期13d。

事件3的事故处理程序是否妥当?如果不妥当,写出正确做法。

答案

参考答案:

事件3中,事故处理程序不妥。

(1)事故处理正确做法:事故发生后,应排除险情,做好标志,保护好现场。

(2)事故调查正确做法:项目经理应指定技术、安全、质量等部门人员,会同企业工会代表组成调查组,开展事故调查。

(3)调查报告正确做法:调查组应把事故经过、原因、损失、责任、处理意见、纠正和预防措施写成调查报告,并经调查组全体人员签字确认后报企业安全主管部门。安全事故调查报告不能只有项目经理一人的签字。
