Apparent defect determination device for structural concrete, and detection method implemented by device

Abstract

The invention belongs to the technical field of road and bridge construction, and particularly relates to an apparent defect determination device for structural concrete, and a detection method implemented by the device. The apparent defect determination device for the structural concrete comprises magnetic devices and a magnetic powder filling device, and is electrically connected with a power supply in a cabinet, wherein the magnetic powder filling device is arranged on the side of a concrete component where an apparent defect is located; and the magnetic devices are arranged on the side opposite to the apparent defect, and the positions of the magnetic devices correspond to the position of the magnetic powder filling device for measurement. The invention further provides the detection method adopting the apparent defect determination device for the structural concrete. The device and the method provided by the invention have the advantages that magnetically conductive ferrous fillers sprayed by the magnetic powder filling device can be sucked into holes and cracks through the magnetic devices, and the magnetically conductive ferrous materials in irregularly shaped holes, cracksor honeycombs on the surface of the structural concrete can be quantitatively measured, so that the measurement equipment and method with high accuracy, simplicity and visualization can be provided for detection of the surface defect of the structural concrete.

Description

technical field [0001] The invention belongs to the technical field of road and bridge construction, and in particular relates to a device for measuring apparent defects of structural concrete and a detection method thereof. Background technique [0002] Concrete, referred to as "concrete (tóng)": refers to the general designation of engineering composite materials in which aggregates are cemented into a whole by cementitious materials. Generally speaking, the term concrete refers to the cement concrete obtained by using cement as the cementitious material, sand and stone as the aggregate; mixed with water (may contain admixtures and admixtures) in a certain proportion, and stirred. Concrete, which is widely used in civil engineering. The appearance defects of concrete components can be divided into honeycomb, pitted surface, holes, slag inclusions, exposed bars, cracks, and the quality of concrete joint surfaces poured at different times. It includes exposed reinforcement...

AI Technical Summary

Problems solved by technology

However, in the prior art such as figure 1 and figure 2 The defects shown include honeycomb, pitted surface, and hole. When measuring honeycomb, pitted surface, and hole, there are still problems that the defect cannot be accurately measured, or the measured data cannot be quantified and refined. Even if it can be quantified, There is also the problem of poor accuracy, which causes the detected results to not be expressed in the form of specific numbers
