Test device and test method for concrete test piece damage crack detection

Abstract

The invention discloses a test device and a test method for concrete test piece damage crack detection. The test device comprises a support, a loading device, a controller and an information collection device used for collecting the surface image of a concrete test piece; the support is provided with an installation base and a counter-force device used for installing the loading device; the installation base is provided with a rotation device; one end of the concreate test piece is fixedly arranged on the rotation device; the loading device is arranged on the other end of the concreate test piece; the central axis of the loading device for loading loads is collinear with the central axis of the concrete test piece; the loading device is provided with a pressure sensor; the outer surface of the concrete test piece is provided with a measurement device used for measuring the surface displacement of the concrete test piece; and the loading device, the information collection device, the rotation device, the measurement device and the pressure sensor are all connected with the controller. The test device has the advantages of high test accuracy, high test efficiency, high result reliability and simple structure.

Description

technical field [0001] The invention belongs to the technical field of building construction detection and testing, and in particular relates to a concrete test piece damage crack detection testing device and testing method. Background technique [0002] Concrete pipe piles are more and more used in offshore projects such as seaport terminals and cross-sea bridges due to their low cost, environmental protection, high strength and stable quality. However, the cracks in the pile body of concrete pipe piles will gradually deteriorate during work, and penetration will occur on the surface and inside, resulting in a decrease in the strength and bearing capacity of the pipe piles. Therefore, it is necessary to focus on the generation, development and Its impact on experimental research and protocol design. Existing concrete material performance tests are often different from actual engineering construction conditions, and cannot fully reflect the degree of concrete performance st...
