问题 问答题

某机电公司承接一地铁机电工程(4站4区间),该工程位于市中心繁华区,施工周期共16个月,工程范围包括通风与空调,给排水及消防水,动力照明,环境与设备监控系统等。工程各站设置3台制冷机组,单台机组重量为5.5t,位于地下站台层。各站两端的新风及排风竖井共安装6台大型风机。空调冷冻,冷却水管采用镀锌钢管焊接法兰连接,法兰焊接处内外焊口做防腐处理。其中某站的3台冷却塔按设计要求设置在地铁入口外的建筑区围挡内,冷却塔并排安装且与围挡建筑物距离为2.0m。 机电工程工期紧,作业区域分散,项目部编制了施工组织设计,对工程进度,质量和安全管理进行重点控制。在安全管理方面,项目部根据现场作业特点,对重点风险作业进行分析识别,制定了相应的安全管理措施和应急预案。 在车站出入口未完成结构施工时,全部机电设备,材料均需进行吊装作业,其中制冷机组和大型风机的吊装运输分包给专业施工队伍。分包单位编制了吊装运输专项方案后即组织实施,被监理工程师制止,后经审批,才组织实施。 在公共区及设备区走廊上方的管线密集区,采用“管线综合布置”的机电安装新技术,由成品镀锌型钢和专用配件组成的综合支吊架系统。机电管线深化设计后,解决了以下问题:避免了设计图纸中一根600*400mm风管与400*200mm电缆桥架安装位置的碰撞;确定了各机电管线安装位置;断面尺寸最大的风管最高,电缆桥架居中,水管最低;确定管线间的位置和标高,满足施工及维修操作面的要求。机电公司根据优化方案组织施工,按合同要求一次完成。

分包单位选择的吊装运输专项方案应如何进行审批?

答案

参考答案:

分包单位选择的吊装运输专项方案审批:

专项方案应由施工单位技术部门组织本大为施工技术、安全、质量等部门的专业技术人员件审核。经审核合格,分包单位技术负责人签字。交总承包单位,总承包单位技术负责人签字。然后报监理单位,由项目总监理工程师审核签字后实施。

专项方案经论证后,专家组应当提交论证报告,对论证的内容提出明确的意见。施工单位应当根据论证报告修改完善专项方案,并经施工单位技术负责人、项目总监理工程师、建设单位项目负责人签字后,方可组织实施。实行施工总承包的,应当由施工总承包单位、相关专业承包单位技术负责人签字。

Yang Yunjing is a tour guide volunteer in Tibet.(西藏) She went there five times as tour guide(导游). Her parents and friends couldn’t understand why she chose the hard work. But facing all the confusion(困惑 ), Yang just smiled and said, “Tibet is full of charm(魅力).”
