Land bridge pile foundation damage detection method
The invention discloses a land bridge pile foundation damage detection method, which belongs to the field of reinforced concrete structure flaw detection, and comprises the following steps: drilling a first soil sample and a second soil sample beside a bridge pier, measuring the content of ferric oxide in the two soil samples, and marking the pile foundation corresponding to the soil sample group in which the iron trioxide content in the first soil sample is 10% higher than that of the second soil sample as a damaged pile foundation. Compared with the defects of high construction cost and high safety risk of the existing excavation inspection mode, the detection method provided by the invention has the advantages of simplicity and convenience in operation, low detection cost and clear discrimination indexes, the engineering quantity is only drilling a soil sample on site, a foundation pit does not need to be excavated, the detection cost is greatly reduced, and the detection efficiency is improved. When the soil samples are taken back to a laboratory, whether the pile foundation is damaged and the reinforcing bars are exposed or not can be judged by only determining the iron trioxide in the soil samples and comparing the content of the iron trioxide in the two soil samples.
本发明公开了一种陆上桥梁桩基破损检测方法，属于钢筋混凝土结构探伤领域，步骤包括，在桥墩旁钻取第一土样和第二土样，第一土样的采集点距离桥墩近，第二土样的采集点距离桥墩远，测定两个土样中的三氧化二铁含量，将第一土样中三氧化二铁含量高于第二土样10%的土样组对应的桩基标记为破损桩基。相对于目前开挖检查的方式存在施工成本高、安全风险大的不足，本发明所提出的检测方法具有操作简便、检测成本低和判别指标清晰明了的优点，工程量仅为现场钻取土样，不用开挖基坑，大大降低了检测成本，土样取回实验室只需测定土样中三氧化二铁这一个项目，通过比较两个土样中三氧化二铁含量的相对高低，即可判断桩基是否存在破损露筋的问题。
