筑岛平台在桥梁大直径群桩基础施工中的应用

Application of Island Building Platform in Bridge Large-Diameter Pile Group Foundation Construction

水中基础筑岛技术是桥梁施工中常用的施工技术,具有成本低、经济可行、安全度高等特点,其在适应多种地形及复杂地质条件方面具有独特的优势。本文结合102省道颍泉周棚至李长营段改建工程颍河特大桥施工案例,围绕筑岛平台方案设计及具体施工工序,详细阐述了筑岛平台技术在公路桥梁大直径群桩基础施工中的应用,可以在类似工程中推广使用。

Underwater foundation island building technology is a commonly used construction technology in bridge construction,which has the characteristics of low cost,economic feasibility and high safety,and has unique advantages in adapting to a variety of terrains and complex geological conditions.Combined with the construction case of Yinghe Grand Bridge of the Yingquan Zhoupeng to Lichangying section of Provincial Highway 102,this paper introduces the scheme design and specific construction process of the island building platform,and elaborates the application of island building platform technology in the construction of large-diameter pile group foundation of highway bridges,which can be popularized and used in similar projects.
