桥涵施工中的钻孔桩施工技术控制对策分析——以念喀大桥桥涵施工为例

Analysis on Control Countermeasures of Bored Pile Construction Technology in Bridge and Culvert Construction——Taking Niangka Bridge and Culvert Construction as an Example

以西藏S5线拉萨至泽当快速通道为例,由于受到特殊地质的影响,该工程中念喀大桥基础采用钻孔灌注桩,论文主要分析该项目施工中的钻孔桩施工准备工作,并提出了针对性的施工技术控制对策,以保证钻孔桩的施工质量。

Taking the expressway from Lhasa to Zedang of Tibet S5 line as an example,due to the special geological influence,the foundation of Niangka Bridge in this project adopts cast-in-situ bored piles.This paper mainly analyzes the preparation work of bored pile construction in the construction of the project,and puts forward the corresponding construction technology control countermeasures to ensure the construction quality of bored pile.
