在渡槽工程的混凝土施工中不可避免的会产生裂缝,对于出现在混凝土表面的裂缝,一般采用在表面涂覆有机涂层、表面贴补或裂缝灌浆等方式来处理,为了验证裂缝处理方法的有效性,采用单面平测法测得裂缝处理前后的波速变化。结合某渡槽工程实例,介绍了单面平测法在混凝土裂缝检查中的应用。
Cracks will inevitably occur in concrete construction of aqueduct. Cracks appearing on the concrete surface are generally treated with organic coating, surface coating or crack grouting. In order to verify the effectiveness of the fracture treatment method The change of wave velocity before and after the crack treatment was measured by the single plane test. Combined with a aqueduct project example, the application of single surface flatness test in concrete crack detection is introduced.
