某桥邻桩施工临界时间控制

在影响群桩基础施工质量的因素中,相邻桩施工时间间隔是一个关键性因素。它不仅仅影响桩基础的施工质量,而且影响桩基础的施工进度,进而影响工程项目的整体进度。作者通过分析某桥相邻桩施工临界时间间隔,通过声波检测方法验证了相邻桩基在临界时间间隔施工情况下桩基混凝土质量,并分析了影响临界时间相关因素。达到了尽量缩短桩基础施工工期、提高整体工程进度的目的。

The Control on the Critical Time Interval between Two Neighbor Piles Construction of A Bridge

The time interval between two neighbor piles construction is a key factor which influences the whole pile foundation progress. The author calculates the critical time interval between two neighbor piles of a bridge, adopts the sonic testing method to verify the concrete quality under the circumstance of critical time and analyses the influencing factor of the critical time in order to shorten the time of constructing the pile foundation and accelerate the progress of the whole engineering.
