Reinforcing structure of composite foundation and construction method of reinforcing structure

WANG XIAOLI / WEI LIQIANG / YAN HUIJIN

The invention relates to a reinforcing structure of a composite foundation and a construction method thereof, and belongs to the technical field of foundation reinforcement. The reinforcing structure of the composite foundation comprises a plurality of prefabricated reinforcing piles and a connecting plate, the connecting plate is used for connecting the prefabricated reinforcing piles, the prefabricated reinforcing piles are provided with reinforcing assemblies at intervals along the axis, and the tops of the prefabricated reinforcing piles are provided with driving assemblies for driving the reinforcing assemblies to slide or rotate; the reinforcing assembly comprises a reinforcing box body and is provided with a matched transmission part matched with the second driving part; the reinforcing box body slides out of the embedded reinforcing column through the first driving part, and then rotation of the reinforcing box body is achieved through the second driving part. The effect of improving the stability and the bearing capacity of the composite foundation is achieved.
