step four: concrete is injected into the lower connecting piece (4) through the grouting hole II (34) until the second concrete cavity (35), the side channel II (36), the side channel III (37), the communication hole II (38) and the flow guide channel (19) are filled with the concrete, and gaps between the threaded hole (17) and the screw groove (15) are filled with the concrete;
step five: clamping and embedding a first protruding part (101) of a first prefabricated wall body (10) between limiting blocks (6) of a first prefabricated part (1) to provide support;
step six: placing a first longitudinal groove (26) of the third prefabricated wall body (20) to be aligned with a first reinforcing rib (28) on the second prefabricated part (2) to provide support;
step seven: concrete is injected into the upper connecting piece (3) through the grouting hole I (21), on one hand, the first concrete cavity (22), the side channel I (23), the communication hole I (24), the grouting channel II (9) and a gap between the first prefabricated part (1) and the first prefabricated wall body (10) are filled with the concrete, so that redundant concrete overflows from the grouting channel I (8), on the other hand, the concrete in the first concrete cavity (22) flows to and fills the main channel (25), the longitudinal groove I (26), the upper groove (27), the drainage channel (31), the lower groove (29) and the longitudinal groove II (33), and the redundant concrete overflows from the grouting hole I (21).
