“真人BBwBBwBBwBBw”成达万高铁真人BBwBBwBBwBBw铜钵河特大桥连续梁顺利合龙

  中新真人BBwBBwBBwBBw网成都12月24日电 (记者真人BBwBBwBBwBBw 刘忠俊)12月24日,随着最后一方混凝土顺利浇筑完成,新建成都至达真人BBwBBwBBwBBw州至万州高速铁路(以下简称“成达万高铁”)铜钵河特大桥128米连续梁顺利合龙,标志着成达万高铁桥梁建设进入攻坚阶段。

  铜钵河特大桥位于四川省达州市高新区斌郎街道红花村,全长1495.75米,跨越铜钵河的128米连续梁是成达万高铁达州段最长桥梁。大桥最大墩高34.5米,跨越水面宽约120米的铜钵河,连续梁全长273.3米,跨度为72米+128米+72米,包含两个T构。

  铜钵河特大桥桥址为村庄、农田及河道冲积平地,地形起伏大,地质条件复杂。且与西渝高铁铜钵河特大桥并行,在桥梁110米范围内成达万高铁主线、西渝高铁主线以及2条联络线共4条线路交叉施工,作业面狭窄,群吊安全管理难度大,吊装、物体打击、设备倾覆安全风险极高。

  “为保障连续梁安全顺利合龙,项目团队实行安全网格化管理,划分责任单元和责任到人,做到‘安全有网,网中有格,格中有人,人尽其责’。”中铁十一局成达万高铁项目部李岳峰称,“双进班组人员”统筹每日施工节奏,与作业人员并肩作战,对挂篮行走、混凝土浇筑等关键工序进行跟班作业,确保了连续梁提前合龙。

  成达万高铁公司达州建设指挥部指挥长张宗伟表示,铜钵河特大桥首座连续梁顺利合龙完成,为成达万高铁达州段按期架梁创造了条件。

  成达万高铁是我国“八纵八横”高铁网沿江通道的重要组成部分,正线长477公里,设计时速350公里。建成后,将形成成都直达中原和京津冀地区的便捷客运通道,对助力成渝地区双城经济圈建设、长江经济带建设等,具有十分重要意义。(完)
