　　5月7日，笔者从邱家嘴立交桥建设现场了解到，为保障邱家嘴立交桥的桩基质量，我市采取超声波透射法对已经完成的桩基进行检测。
　　笔者在现场看到，一名检测工作人员操作着超声波透射仪器，正在查看相关的数值，另外的检测工作人员正与现场的施工人员一道，将检测的线路放入已经完工的桩基当中。
　　据施工监理方介绍，采取超声波检测主要是针对设计深度、桩的完整性以及密实度进行检查，防止在混凝土浇筑中可能存在泥浆上浮或者桩基中混凝土不均匀的情况，从而影响桩的质量。检测等级分为4类，一类便是桩身完整，二类是有轻微缺陷但不影响桩基的使用，三、四类则是桩基有明显缺陷，是废桩，必须拆除重做。
　　“目前，我们已经对73根桩基进行了超声波检测，检测结果全是一类桩。”现场的施工监理人员告诉笔者，除桩基之外，监理方还将对机械连接、承台结构、钢筋梁等一系列涉及邱家嘴立交桥建设质量的作业进行现场督查及检测，保障邱家嘴立交桥工程质量过关。
