文章介绍了在桥头搭板注浆检测中引用地质雷达的背景、地质雷达应用原理,并以实例说明桥台搭板检测中引进这一技术对公路病害治理的现实意义;通过在桥头搭板压浆处理中引进地质雷达检测技术,施工前对桥头搭板下的病害情况进行检测,根据检测情况确定处置方案以及费用预测,施工完成后对处理情况再次进行检测和对比分析,确保达到处理效果;为进行现场实时质量监控寻找有效的无损检测手段,经具体实施和验证,取得了比较满意的效果,为以后同类工程的施工提供参考。
This paper introduces the background of using geologic radar in the test of the bridge head grouting and the application principle of the geologic radar, and illustrates the practical significance of introducing this technology to the treatment of the road disease in the boarding test of the abutment. In the process of slurry treatment, the technology of detecting geologic radar is introduced. Before the construction, the disease conditions of the bridge head slab are detected, and the disposal plan and cost forecast are determined according to the detection conditions. After the completion of the construction, the treatment conditions are again tested and compared to ensure the treatment effect. In order to search for effective non-destructive testing methods for on-site real-time quality monitoring, the concrete implementation and verification have achieved satisfactory results and provided references for the construction of similar projects in the future.
