试论桥梁深水桩基础钻孔灌注桩施工

On bored pile of bridge deep water pile foundation

介绍了桥梁深水桩基础钻孔桩的工作平台,从护筒埋设、泥浆制备、钻进成孔、灌注水下混凝土等方面,探讨了钻孔灌注桩的关键施工技术,并提出了施工中防塌孔及防缩径措施,保证了桥梁桩基础的施工质量。

The paper introduces the working platforms of the bored piles of bridge deep water piles foundation, explores the key construction tech- nique for the bored piles from the casing burial, mud manufacturing, drilling holes, and grouted underwater concrete, and points out the anti-col- lapse holes and anti-shrinkage holes, so as to ensure the construction quality of the bridge pile foundation.
