在混凝土结构施工过程中,由于质量管理或施工技术等原因,造成的混凝土内部缺陷,如内部孔洞、疏松或分层等,往往因混凝土表面尚好的假象而难以发现,更不能得到及时补强处理,形成了建筑结构的隐息,影响着整个建筑物的安全度。近年来,全国各地在超声波测缺检测技术的研究和应用上有了很大的发展,可以在不损伤建筑结构的前提下探测混凝土的内部缺陷。我所自引进英制“PUNDIT”超声仪以来,在混凝土内部缺陷探测方法的研究方面做了一些工
During the construction of concrete structures, due to quality management or construction techniques, the internal defects of concrete, such as internal holes, looseness, or delamination, are often difficult to find because of the illusion that the concrete surface is still good, and it cannot be reinforced in time. The formation of a hidden structure structure, affecting the safety of the entire building. In recent years, great progress has been made in the research and application of ultrasonic flaw detection technology throughout the country, and the internal defects of concrete can be detected without damaging the building structure. Since I introduced the British “PUNDIT” ultrasound system, I have done some research on the detection methods of concrete internal defects.
