Description

Technical Field

[0001] The present invention relates to the technical field of prefabricated building detection, and in particular to a prefabricated building sleeve grouting quality detection device and detection method. Background Art

[0002] Prefabricated concrete structures are connected by various prefabricated components. As an important connection technology in the construction process of prefabricated building structures, sleeve grouting is used to connect vertical or horizontal structures. Due to its technical advantages such as wide application range, short anchoring length, high reliability, and high positioning accuracy requirements, high grouting difficulty, and difficult quality detection, it has become a hot issue in the construction process. The density of the slurry in the grouting sleeve directly affects the connection quality between the components. The impact echo method is a commonly used detection method for building components. It uses a short mechanical impact (such as tapping the concrete surface with a small hammer) to generate low-frequency stress waves. The stress waves propagate into the interior of the building component and are reflected back by defects and the other plane of the component. These reflected waves are received by the sensor, and the reflected wave signal is analyzed to determine whether the grouting sleeve is filled densely.

[0003] At present, when the impact echo method is used to detect the quality of precast concrete shear wall sleeve grouting, it is necessary to first clean the shear wall surface, remove the raised mortar and impurities at the shear wall detection position, and avoid affecting the transmission and reception of stress waves. Then, the detection points are measured and marked on the shear wall. After marking, the staff needs to attach the sensor to the detection position, and then knock on the corresponding points to complete the detection of each detection point one by one. This detection method is not only cumbersome to operate, but also difficult to control the sensor and the knocking point accurately during the detection, and it is difficult to keep the manual knocking force uniform, which affects the accuracy of the detection. Therefore, a prefabricated building sleeve grouting quality detection device and detection method are needed to solve the above problems. Summary of the invention
