8月7日,由中铁十六局承建的平塘江口至六景航道碍航设施改造工程——黎钦铁路飞龙郁江特大桥主桥正式启动主塔水中钢管桩围堰施工,标志着该桥正式进入水下主体结构施工攻坚期,为平陆运河通航能力提升筑牢坚实基础。

据了解,项目位于横州市新福镇,紧邻南宁港六景港区郁江航道,距平陆运河平塘江口上游约14公里,是平陆运河连通西江水系与北部湾海域的核心衔接枢纽。新建主桥全长582.65米,采用混合梁斜拉桥结构。此前,原黎钦铁路飞龙郁江特大桥通航净空高度仅10米,无法满足5000吨级江海直达船舶经平陆运河驶入郁江、直达南宁港的通航需求。为适配平陆运河5000吨级通航标准,项目将桥面轨面整体抬高8米,改造后通航净空提升至18米,彻底破除原有航道通航瓶颈。
据介绍,项目创新采用锁扣钢管桩施工与收尾桩基施工同步作业的方案,预计缩短关键线路工期20天,大幅提升施工效率。截至目前,主桥已完成桩基76根、承台2个、墩身1个,施工进度稳步可控。此次钢管桩围堰施工的顺利启动,成功打通了大桥水下主体施工的关键通道,攻克了下部结构建设的核心难关,为后续主体工程快速施工奠定坚实基础。
