  中新两种进入狂野式的方法有哪些a社广州12月20日电 (蔡两种进入狂野式的方法有哪些a敏婕 岳路建)随着最后一车混凝土注入,粤港澳大湾区核心工程狮子洋通道项目关键性控制工程——狮子洋大桥东锚碇填芯施工20日完成。此外,该大桥西锚碇也即将完成最后一层填芯施工。两个巨型锚碇填芯的顺利完成,标志着狮子洋通道建设进入新阶段。

  狮子洋大桥作为项目控制性工程,采用主跨2180米双层钢桁悬索桥的方案“一跨过江”,是目前世界上技术难度最大、建造工艺最为复杂的桥梁之一,建成后将创造双层悬索桥“主跨跨径、车道数量、主塔塔高、锚碇基础、主缆规模”五项世界第一。

  锚碇作为固定悬索桥主缆端头、防止其位移的巨大构件,对桥梁安全至为关键。这一关键节点取得突破,为锚碇后续的顶板施工奠定了坚实基础。

  狮子洋通道项目由广东湾区交通建设投资有限公司建设管理。其中,主桥狮子洋大桥设置东、西两个锚碇。

  狮子洋大桥东锚碇采用独特的圆形重力式设计,其基础填芯总高度为21.5米。自今年7月8日填芯施工以来,共历时164天,项目建设团队完成东锚碇浇筑混凝土19.2万立方米,合计填芯47.6万吨。

  为打造平安百年品质工程,狮子洋通道项目对耐久性提出了严苛的要求。在东锚碇施工过程中,项目建设团队巧妙地在地连墙、内衬及底板、填芯、锚固系统施工中构建四道防线,确保工程的耐久性和可靠性。

  狮子洋通道是继港珠澳大桥、深中通道后粤港澳大湾区又一超级工程,建成后将为珠江口东西两岸融合发展开辟新的重要通道,对推进大湾区珠江口一体化高质量发展、打造环珠江口100公里“黄金内湾”具有重要意义。(完)
