Abstract

The invention discloses a detecting system and a detecting method for apparent defects and internal quality of a dam slab. The system comprises a mobile base station module, a defect detecting module,a wireless transmission module and a remote control module, wherein the defect detecting module and the wireless transmission module are loaded on the mobile base station module; the remote control module remotely controls the mobile base station module and the defect detecting module by the wireless transmission module. The method comprises the following steps: firstly, carrying out high-definition photographing on the dam slab by using a 3D high-definition photographing unit; carrying out preliminary estimation on defects by background analysis; selecting whether a geological radar is usedfor carrying out void detection on the dam slab or not according to an estimate result; giving out evolution prediction of the defects by combining with a high-definition image detection result. In aword, the detecting system and the detecting method disclosed by the invention have the advantages that functions are diversified, detection time is saved, and detection precision and efficiency are improved.

Description

technical field [0001] The invention belongs to the technical field of non-destructive testing of hydraulic concrete, and in particular relates to a detection system and method for appearance defects and internal quality of a dam face plate. Background technique [0002] The face rockfill dam has a history of more than 100 years. According to incomplete statistics, there are more than 600 face dams built or under construction at home and abroad, including more than 300 in China. Rockfill face dams often have large deformation of the dam body and different degrees of cracks in the face face, including longitudinal cracks, transverse cracks, and shrinkage network cracks. The causes of cracks are mainly related to the thickness of the river bed cover, dam building materials, construction factors, and the impact of reservoir water storage, etc., but the hazards of cracks are obvious. The appearance of cracks will lead to damage to the face plate and leakage of reservoir water, ...
