钻孔桩水下混凝土施工质量控制

在高速公路工程建设中,各类桥梁项目在所有建筑工程项目中所占的比例越来越大,桩基础也随之被大规模应用。水下混凝土浇筑是桥梁桩基础施工中应用普遍的施工工序,其质量的好坏,是桥梁能否正常发挥功能的关键。文章以某项目特大桥钻孔桩水下混凝土施工为例,总结和论述了在桩基础水下混凝土浇筑过程中需注意的事项及常见问题,并提出了常见问题的预防措施。

Quality Control in Constructing Bored Pile Underwater Concrete

In expressway engineering works,pile foundation is widely applied,for bridge engineering accounts for a large proportion of the whole construction works.Underwater concrete pouring is a process in the building of bridge pile foundation and the quality will impact the performance of the bridge.Taking some underwater concrete construction of a huge bridge bored pile as an example,the paper summarizes and elaborates some problems deserve attention in the course of building and puts forward some prevention measures.
