西康高铁全线铺轨正式启动 中新网西安10月11日电(张远 刘盼利)11日，随着首对500米长钢轨平稳铺设在西康高铁西安东站至牛背 梁站区间的道床上，由西成客专陕西公司建设、中铁一局负责铺轨施工的西康高铁全线铺轨正式启动， 西康高铁建设进入全面攻坚阶段。 西康高铁穿越秦岭山脉，地质结构十分复杂，桥隧比高达94%。全线正线铺轨341.49公里、站线铺轨 19.62公里，道岔铺设78组，道岔运输难度大，交叉施工作业多，安全风险和精准度要求非常高。 "今天西康高铁正式启动铺轨，标志着西康高铁建设进入全面攻坚阶段，是西康高铁建设的阶段性重大 成果，我们将在10月至12月间进行铺轨作业，为后续工程验收和联调联试打下坚实基础。截至目前，西 康高铁20座隧道已全部贯通，26座桥梁主体已全部完成，406孔箱梁已全部架设，新建6座站房已完成设 计总量的70%，四电集成工程整体完成超72%，无砟轨道完成设计总量的97%，西康高铁全线建设进 入'加速度'状态。"西成客专陕西公司西康指挥部指挥长李战江说。 中国铁路西安局集团有限公司作为西康高铁开通后的运营主体单位，专门成立验收开通工作组提前介 入，对西康高铁铺轨施工进行技术指导，组织 ...

"广州东环城际铁路（番禺-白云机场北）需穿越多种复杂地层及城市核心区，施工难度高，被誉为'地 下穿针'。"相关负责人介绍，面对高压线交错、建筑密集、水文复杂等多重挑战，项目建设团队积极开 展多项技术攻坚。 其中，帽峰山站是全线体量最大、结构最复杂且与220KV高压线平行重叠距离最近的地下双层明挖车 站。项目建设团队创新研制"侧墙中板一体式衬砌台车"，实现侧墙与中层板混凝土同步浇筑，将单次浇 筑周期从7天压缩至两天，效率提升3.5倍；岑村站场地极窄、交通忙，为此项目建设团队通过"半盖挖 +跳仓法"等精细化协同施工，建成324米地下车站，实现道路不断、居民不扰、管线不爆目标。 在龙大、智龙盾构区间，项目建设团队累计开仓392次零失误，突破9.6公里花岗岩区，实现建筑零沉 降、隧道零渗漏。采用自行式液压仰拱栈桥，将隧道划分为上下同步作业区间，实现运渣进料与仰拱施 工并行，成功完成断面超800平方米、深达65米的超深盾构竖井，创造了国内超深盾构竖井施工新纪 录。 此外，项目建设团队首次应用9米级双模盾构，实现软硬交替地层的高效掘进。设计团队创新提出基于 气动效应的城际铁路隧道净空断面标准，并构建"站隧一体"防灾体系， ...
