Embodiment Construction
[0032] In order to better clearly express the technical solution of the present invention, the present invention will be further described below in conjunction with the accompanying drawings.
[0033] The assembly method of the existing prefabricated components is that after the grouting is completed, it is necessary to detect the degree to which the grouting material fills the steel bar accommodation hole, and whether the grouting material is completely filled in the horizontal splicing joint between the upper component and the lower component. This test is called Grout filling test.
[0034] figure 1 It shows a schematic flow chart of a method for detecting the filling degree of a grouting material according to a specific embodiment of the present invention. Those skilled in the art understand that in such an embodiment, in the actual construction process, it is necessary to assemble the upper and lower two The lower end of the upper member has a steel bar accommodation hol...

Abstract
The invention provides a detection method of the filling degree of a grouting material. The detection method comprises the steps as follows: a, an ultrasonic transmitting point is set on the front side of a component of a to-be-detected part; b, a plurality of ultrasonic receiving points are set on the back side of the component of the to-be-detected part, and the plurality of ultrasonic receiving points are circularly symmetrically distributed with the projection of the ultrasonic transmitting point on the back side of the component as the circle center; c, an ultrasonic transmitting transducer is placed at the ultrasonic transmitting point to transmit ultrasonic waves, ultrasonic receiving transducers are sequentially placed at the plurality of ultrasonic receiving points to receive ultrasonic waves, and the ultrasonic detection acoustic parameter corresponding to each ultrasonic receiving point is acquired; d, the filling degree of the grouting material of the to-be-detected part is judged according to the plurality of ultrasonic detection acoustic parameters corresponding to the plurality of ultrasonic receiving points. The method is simple, practical and convenient to operate and calculate and has extremely high commercial value.
Description
technical field [0001] The invention relates to the field of detection of concrete products, in particular to a detection method for filling degree of grouting material. Background technique [0002] The assembly method of the existing prefabricated components is that the lower end of the upper component has a steel bar accommodation hole, the upper end of the lower component extends out of the steel bar, and the steel bar extends into the steel bar accommodation hole when the upper component and the lower component are spliced together. At the same time, the upper member is provided with a grouting port and a grouting port communicating with the steel bar receiving hole, and the mortar is continuously injected through the grouting port, and when excess mortar flows out through the grouting port, the grouting step is completed. After the grouting is completed, it is necessary to detect the filling degree of the grouting material injected into the steel bar accommodation ho...
