Detection method of grouting compactness for assembly-type shear wall pipeline

Abstract

The invention relates to a detection method of grouting compactness for an assembly-type shear wall pipeline, and belongs to the technical field of the quality inspection of building engineering. The method comprises the following steps: step I, wearing a combined detection apparatus; step II, detecting an impact echo; and step III, measuring the compactness. According to the detection method, elastic wave data is acquired by virtue of a sensor, an equivalent wave velocity is calculated by adopting computing software, and spectral analysis is performed on the obtained equivalent elastic wave velocity of other test points according to the calculated equivalent wave velocity and converted to a color contour map which is convenient to intuitively judge. The detection method is high in field operability, simple in data acquisition, unapparent in response to the signal of metal materials such as steel reinforcing bars and the materials such as plastic pipelines and has clear signal response to the grouting compactness of the pipeline, the analysis can be performed according to the spectral data converted from the equivalent wave velocity, the data signal can be converted to the color contour map for convenience in intuitive display, and the beneficial effect is remarkable.

Description

technical field [0001] The invention relates to a method for detecting the grouting compactness of a prefabricated shear wall pipeline, belonging to the technical field of construction engineering quality detection. Background technique [0002] Prefabricated buildings have the advantages of environmental protection, quickness, and good quality of component production, and are currently being more and more widely used in housing industrialization. For prefabricated shear walls with prefabricated structures connected by grout-anchor, the connection method mainly adopts grout-anchor connection of pipeline pressure grouting (high-strength slurry), etc. The compactness of pipeline grouting in the wall directly determines the safety of the structure and durability. Compared with the wide application of grouting technology in bridge engineering, the grouting technology of prefabricated buildings has just emerged. Since the pipelines in prefabricated buildings are smaller and sho...
