PVC pipe and thick wall steel tube composite hollow recycled concrete pile
The invention discloses a PVC pipe and thick wall steel tube composite hollow recycled concrete pile, which is mainly prepared from PVC pipes, a round reinforcement cage framework, thick wall steel tubes and recycled concrete, wherein the round reinforcement cage framework and the thick wall steel tubes are arranged in PVC pipes, and the three are concentrically arranged; recycled concrete is poured into the PVC pipes and the thick wall steel tubes; the built-in thick wall steel tubes are capable of improving single-pile bearing capacity and non-deformability by a large margin; the externally covered PVC pipes are capable of effectively preventing pile bodies from being corroded and improving pipe body durability; at the same time, the recycled concrete inside can be jointed restrained by the PVC pipes and spiral stirrups, thus further enhancing composite pile bearing capacity; and waste concrete can be used as recycled aggregate, thus being favor of popularization and application of recycled concrete in building foundation engineering. In short, the PVC pipe and thick wall steel tube composite hollow recycled concrete pile has the advantages of good pile formation quality, high bearing capability, good non-deformability, good durability, small environment influence, quick construction speed and the like.
