When being in the milk not full, the grouting material in grouting material and sleeve in pulp duct be it is discontinuous, in the transmission path of impact force
There is cavity zone in range, demoulding sliding can occur between the grouting material in pulp duct and pulp duct inner wall；
Whether position of the record impulse detection face in pulp duct again, generate in pulp duct bright according to impulse detection face
Aobvious displacement judges full weight of being in the milk, if impulse detection face generates obvious displacement, determines that grouting is not full in sleeve, it is on the contrary then
Determine that grouting is full in sleeve.
10. the wall as claimed in claim 8 convenient for grouting full weight detection, which is characterized in that further include pre- for judging
The method of sleeve grouting full weight is connected in component processed:
Grouting material end face in pulp duct close to prefabricated components surface side is arranged to ultrasound detection face, the ultrasound detection
Face has even curface, and the pulp duct is vertically arranged with ultrasound detection face；
Arrange ultrasonic transducer on ultrasound detection face, the ultrasonic transducer being capable of excitation ultrasound simultaneously on ultrasound detection face
Wave and reception ultrasonic wave；
After ultrasonic transducer excitation ultrasound wave, ultrasonic wave is propagated along pulp duct to the prefabricated components back side, when sleeve grouting is full
Man Shi, without cavity zone within the scope of the propagation path of ultrasonic wave, ultrasonic wave reflects at the prefabricated components back side, when sleeve is in the milk
When not full, there is cavity zone within the scope of the propagation path of ultrasonic wave, ultrasonic wave is in pulp duct close to the filling of sleeve side
Slurry defect end scatters；The ultrasonic transducer receives the echo-signal of ultrasonic wave；
Full weight of being in the milk is judged according to whether having apparent echo-signal in the corresponding regional scope in pulp duct.
