Grouting connecting structure of prefabricated part and construction method thereof
The invention discloses a grouting connecting structure of a prefabricated part and a construction method thereof. The grouting connecting structure comprises grouting sleeves and an observation pipe, wherein the grouting sleeves are arranged at the bottom of the prefabricated part in an embedded mode and serve for insertion of butt-joint reinforcing steel bars, a grouting port is formed in the lower portion of the sleeve wall of each grouting sleeve, a grout discharge port is formed in the upper portion of the sleeve wall of each grouting sleeve, and grouting holes and grout discharge holes corresponding to the grouting ports and the grout discharge ports are formed in the prefabricated part; the observation pipe is arranged at the bottom of the prefabricated part in an embedded mode, a pipe port at a first end of the observation pipe is formed in the end face of the bottom of the prefabricated part, a pipe port at a second end of the observation pipe is formed in the surface of the side wall of the prefabricated part, and the arrangement location of the pipe port located at the second end of the observation pipe is higher than the top positions of the grouting sleeves. According to the grouting connecting structure of the prefabricated part and the construction method thereof, by pre-embedding the observation pipe at the lower end of the prefabricated part, the grouting sleeves and the observation pipe are filled with grout, by means of the intrinsic pressure of the filling grout, automatic grout replenishment is completed when the liquid level at the tops of the grouting sleeves declines, and the observation pipe is utilized for raising the grout liquid level, so that it is convenient for workers to make observation, the grout is replenished in time, and the grout compactness is guaranteed.
