Detection system and detection method for grouting quality of fabricated structure

Abstract

The invention discloses a detection system for the grouting quality of a fabricated structure. Meanwhile, the invention discloses a method for detecting the grouting quality of the fabricated structure by applying the detection system. A plurality of data can be acquired at one time; accurate and stable results are ensured by analyzing a plurality of data; the graduated scale on the device can directly record the defect position and size; a movable adjusting seat can be used for sleeves with different lengths; the position thickness and inclination angles corresponding to a plurality of measuring points are tested; through a mathematical relation, the wave velocity of each point is calculated in sequence, the wave velocities of the test signals are compared according to a wave velocity curve graph obtained by calibrating the sleeve well on site, and then whether the sleeve has defects or not or whether the defects are located at specific positions or not is judged. The on-site personnel testing is greatly facilitated through the detection system, and then the test efficiency and accuracy are improved.

Description

technical field [0001] The invention relates to the field of detection of grouting quality of prefabricated buildings, in particular to a detection system and detection method for the quality of grouting of prefabricated structures. Background technique [0002] Prefabricated structural grouting is a composite material with superior performance. During the compression process, the core concrete is in a three-dimensional compression state with the help of the sleeve’s hoop constraint on the core concrete, so that the core concrete has higher compression resistance. strength and compression deformation capacity, and at the same time, the sleeve can enhance the geometric stability of the sleeve wall and change the instability mode of the empty sleeve with the support of the inner concrete. [0003] The grouting of prefabricated structures is a concealed project. If the construction quality is not guaranteed, problems will arise in the bearing capacity, stress and strain, stiffn...

AI Technical Summary

Problems solved by technology

[0004] For the quality inspection of prefabricated structure grouting, wire drawing method, embedded strain gauge method, ray scanning method and impact echo method are mainly used for testing. In actual operation, because the project has been formed, wire drawing method and embedded strain gauge method cannot The ray scanning method is more radiant to the human body and the cost is higher. Most of the solids use the shock echo method to test and determine the quality of the sleeve grouting
