柴米河特大桥全桥共10联36跨，总跨径达1154米，需架设预制箱梁306片。本次架设作业面临挑战众多，除涉及梁型多、斜交角度多、同角度梁长不同等 情况外，还有涉路涉河技术复杂等诸多不利因素。 为确保工程顺利完成，参建单位经过多轮技术研讨，最终施工采用施工效率高、安全性高、场地占用小的架桥机架梁方法。在箱梁架设前，参建单位多次 完善架设方案，并对现场施工人员进行详细的技术交底和安全培训，确保每个环节都严格按照规范执行。架设过程中，参建单位施工人员紧密配合，严格 落实技术交底与隐患排查机制，有效防控各类施工风险，确保了每一片箱梁就位精准稳固。 扬子晚报网1月17日讯(通讯员鲍恩山记者高峰)继1月9日连宿高速公路灌云至沭阳段(宿迁段)跨X101大桥实现贯通后，近日，该项目再次迎来重大捷讯 ——柴米河特大桥实现全幅贯通，这标志着项目建设进程中的又一关键节点顺利完成。 ...

（来源：工人日报） 2025年12月23日凌晨1时58分，北天山隧道正式贯通。精伊高速公路G577项目最后一个控制性工程完 工。这条打通北天山的高速公路，将成为联通伊犁河谷最便捷的通道——此前，从乌鲁木齐到伊犁，走 连霍高速翻山越岭，最快要7个小时，还时常因暴雪封路。精伊高速另辟蹊径，修建长大隧道、高墩大 桥，将通行时间压缩了1个多小时。 关键技术挑战是建设者必须啃下的"硬骨头"。博尔博松特大桥最高墩144米，混凝土高扬程泵送及大体 积混凝土浇筑和养护质量控制等难度较大。而且，其最大跨度为160米，对挂篮施工线型控制、合拢高 差控制等要求高，所有工装抗风载要求高。而承台均位于陡峭山腰，便道施工难度大，且存在边坡下滑 风险。 "塔吊及电梯倾覆风险、高空作业风险、起重吊装风险、0号块模板安拆风险、挂篮行走倾覆风险、便道 行车安全风险等，这些都是主要风险控制点，时时刻刻揪着心。"石文科说。 压力与成就感某种程度上成正比。身为指挥长，项目建设过程中自然也有令他非常兴奋的时刻。比如博 尔博松特大桥合龙。"4年前从下面开始打桩，我一直是站在桥底往上看，今年6月30日合龙后能站在桥 上往下看，很有成就感。" 如今，北天隧道 ...
