Ultrasonic three-dimensional detecting device for surface crack of concrete and detecting method thereof

Abstract

The invention relates to an ultrasonic three-dimensional detecting device for a surface crack of concrete and a detecting method thereof, wherein the supersonic three-dimensional detecting device and the detecting method belong to the technical field of engineering ultrasonic nondestructive testing. The ultrasonic three-dimensional detecting device is composed of a bracket (1), bracket supporting legs (2), fixed armrests (3), a leveling instrument (4), a slide block (5), an ultrasonic planar probe (6), a wheel type encoder (7), a slidable power-assisting armrest (8), a slide block center marking point (9), data transmission wires (10) and an ultrasonic instrument (11). The detecting method comprises the steps of preparing equipment, debugging the equipment, arranging field detecting wires, acquiring data, and analyzing and processing the data. The ultrasonic three-dimensional detecting device and the detecting method are advantageous in that small detection error for depth of a shallow crack is realized; large amount of acquired data is realized, acoustic parameters and distance parameters which are acquired are simultaneously recorded through the encoder and the ultrasonic planar probe; and through the acquired data, a three-dimensional coordinate distribution map is drawn on a three-dimensional coordinate system, and objective data can be supplied for scientifically analyzing the forming reason of the shallow crack.

Description

Technical field: [0001] The invention relates to an ultrasonic three-dimensional detection device for shallow cracks on the concrete surface and a detection method thereof, which belongs to the technical field of engineering ultrasonic nondestructive testing equipment and is suitable for detection of shallow cracks on the concrete surface whose depth does not exceed 50 cm. Background technique: [0002] The application field of this technology is mainly aimed at the following three types of concrete components: 1. Cracked concrete components in construction projects; 2. Cracked concrete components due to natural disasters (earthquakes, floods, mudslides) or traffic accidents (vehicle and ship collisions, etc.); 3. Some For special cracked concrete members that require long-term monitoring, especially some stressed cracked concrete members, according to the relevant regulations of the Ministry of Transport, the cracked concrete members must be tested to ensure that the concret...

Problems solved by technology

However, there are still three problems in the existing device in the actual detection work: 1. The measured shallow crack depth and the actual depth have a large error; 2. The internal direction of the shallow crack cannot be measured; 3. The accuracy of data collection is poor. less data collection
