4) And injecting micro-expansion fine stone concrete into two sides of the water stop wing ring by using the feed inlet, and inserting and welding a steel plate into the feed inlet before the initial setting of the concrete so as to seal the feed inlet.
The beneficial effect of above-mentioned scheme is:
1) According to the invention, the horn-shaped water stop wing ring of the water stop sleeve is implanted into the concrete structure to enlarge the path of water in the upstream surface of the structure and air flowing into the upstream surface;
2) According to the invention, the water-stop sleeve is used as a counter-pulling member, so that the blocking quality of concrete around the water-stop sleeve is greatly improved, and the water tightness and the air tightness of the structure are improved.
