摘要
结合国道316线安全隐患整治一期工程石潭溪大桥主桥墩深水桩基施工全过程中所遇到的多种难题,简要介绍水下桩基础在复杂工程地质施工中,通过水上作业平台设计、辅助机械选择、桩基成孔清孔工艺改进、长距离泵送水下混凝土灌注等关键施工技术对桩基施工质量及进度的积极影响。
Combining with various difficulties encountered in the construction of deep-water pile foundation of main pier of Shitanxi Bridge in the first phase of the safety hidden danger regulation project of National Highway 316,this paper briefly introduces the underwater pile foundation in complex engineering geological construction through the design of water operation platform,the selection of auxiliary machinery,the improvement of pile foundation hole-forming and hole-clearing technology,and long distance pumping underwater. Concrete grouting and other key construction technologies have a positive impact on the quality and progress of pile foundation construction.
