继承与【 】机制,是面向对象程序中实现重用的主要手段。
为了满足炼钢对铁水产量和质量的需要,某钢铁公司对现有1260m3高炉扩容大修至2200m3,同时对落后的系统进行改造,以使扩容改造后的高炉更加高产、优质、低耗、长寿和环保。通过投标竞争,某工程公司以工程总承包方式承接了该项目,合同范围包括工程设计、设备材料采购、工程施工、人员培训、调试、试生产、保产一揽子服务。为了尽可能减少对现有生产系统的影响,与传统高炉大修不同,本项目是在原高炉旁先建好新高炉本体,然后拆除老高炉,将新高炉整体推移到老高炉位置,高炉仅仅停炉45天便恢复生产。由于大部分工程是在边生产边施工的情况下完成的,项目的特点是场地狭窄,生产和施工交叉,立体作业交叉,旧结构、旧设备修复利用量大,与传统高炉大修相比,施工中的不安全因素更多,安全管理工作更复杂。
问题:
①对于交钥匙总承包工程,安全组织机构有无必要分层次?如有必要,分几个层次较为合理?
②施工中安全管理的六项基本原则是什么?
③施工安全是一项技术性很强的工作。本项目中,如何与安全技术统一起来?
