[0004] Early grouting compactness detection relies on manual sampling and physical laboratory testing, which usually has problems such as uneven sampling, large manual operation error, long time consumption, etc., and is not suitable for large-area or real-time monitoring occasions. With the development of technology, non-destructive testing technology appears, which uses ultrasonic waves or rebound instruments to test compactness. However, some compactness detection devices cannot be adjusted according to the height of grouting when in use, and when it is necessary to detect horizontally arranged prestressed ducts or curved ducts, the detection direction needs to be arranged along the extension direction of the duct axis.
