A detection method and detection structure of grouting compactness of prefabricated components

Abstract

The invention discloses a detection method and a detection structure for grouting density of prefabricated parts. The detection method comprises the following steps: providing at least one first prefabricated part and a second prefabricated part, preserving a grouting construction gap between the first prefabricated part and the second prefabricated part, and forming opposite grouting interfaces between the first prefabricated part and the second prefabricated part; arranging prefabrication testing points on the grouting interfaces of the first prefabricated part or / and the second prefabricated part, and connecting the prefabrication testing points with a signal receiver; grouting size into the grouting construction gap; when the size in the grouting construction gap triggers the prefabrication testing points, transmitting signals to the signal receivers from the prefabrication testing points; based on the signals transmitted from the prefabrication testing points, judging the grouting density degree of the grouting construction gap. As the prefabrication testing points are arranged on the grouting interfaces, the density degree of size grouting in the grouting construction gap can be detected, the size can be completely filled without bubble, and the grouting connection quality between the prefabricated parts can be ensured.

Description

technical field [0001] The invention relates to the technical field of engineering construction, in particular to a detection method and a detection structure of the grouting compactness of prefabricated components. Background technique [0002] The current grouting technology is widely used in various sectors of the national economy such as petroleum, chemical industry, power station, metallurgy, nuclear power, and national defense. With the continuous improvement of construction technology, the need for grouting has also increased. In order to improve the quality of grouting and improve the efficiency of grouting equipment, the requirements for the density of grouting are becoming more and more stringent. [0003] The current domestic grouting technology generally has the problem that it is difficult to control the compactness of grouting materials in confined spaces and the grouting quality cannot be directly reflected in the parts at the bottom of the structure that are...
