　　11月16日，中铁四局潮漳高速TJ4标桂坑特大桥首墩成功浇筑。中铁四局潮漳高速TJ4标正线全长8.11公里，此次浇筑为桂坑特大桥左幅14#墩，该桥地形复杂，场地狭小，施工难度大，为本标段控制性工程。

　　为确保首墩成功浇筑，该部提前谋划、科学组织，合理制定施工方案，钢筋安装、模板安装、混凝土浇筑等工序严格把关。一方面钢筋统一加工制作，模板安装完毕校正垂直度，采用全站仪定出墩身控制点，并用垂球法调整模板的竖直度；另一方面对现场施工人员进行技术交底及安全质量交底，浇筑过程中严格执行报检、旁站制度，合理组织安排砼罐车运输时间顺序，做好工序衔接，对混凝土振捣的监督和指导，确保墩身质量。

　　此外，针对墩身施工中高空作业，不断强化对安全知识的培训，对起重作业、模板拼装等施工环节，还派专人现场盯控，确保施工现场安全受控。同时该部组织召开首墩总结会，认真查找浇筑过程中存在的问题，为其它墩身施工积累经验。
