Description
Technical Principle:
The reinforced sleeve grouting is connected with a metal sleeve inserted into the steel bar, and is poured with high-strength, early-strength, and micro-expandable cement-based grouting material. The rigid sleeve restrains the micro-expandable grouting material on the surface of the steel bar. A positive force is generated between the inner sides of the cylinder, and the steel bars generate friction on the rough, ribbed surface with the help of the positive force, so as to realize the stress transfer between the stressed steel bars.
