Description
technical field [0001] The invention relates to the technical field of non-destructive testing of existing buildings, in particular to a ground-penetrating radar testing device and method for an external thermal insulation system. Background technique [0002] Under the guidance of the national strategy of energy saving and emission reduction, the external wall insulation system is not only suitable for new construction projects, but also for the renovation of old buildings because of its advantages of protecting the main structure, obvious thermal insulation effect, and wide application range. The most widely used form of external wall insulation. However, due to the variety of building structures, complex construction techniques, chaotic construction management, and uneven insulation materials, the external insulation system has quality problems such as hollowing, cracking, and falling off, which has led to many accidents. For example, Shanghai Pudong Shengshi The Nanyuan...
