PVC pipe wrapped inner supporting cross prestress recycled concrete tubular pile
2015
The invention discloses a PVC pipe wrapped inner supporting cross prestress recycled concrete tubular pile mainly formed by a PVC pipe, a round reinforcement cage framework, cross steel ribs and recycled concrete. The round reinforcement cage framework and the cross steel ribs are arranged in the PVC pipe, and a round inner cavity is formed in the PVC pipe by the recycled concrete. The round reinforcement cage framework is formed by welding longitudinal prestressed tendons and spiral stirrups. A PVC pipe wrapped pile body resistant to corrosion, light and high in strength can be effectively prevented from being corroded, the corrosion problem of the tubular pile is solved, and the durability of a pile foundation is improved. The inner supporting cross steel ribs can fully achieve the respective advantages of steel, prestressed reinforcement and concrete, the stress performance of the recycled concrete is improved, the bearing capacity and stability of the single pile are improved, the lateral rigidity of the pile body is increased, and transverse deformation is reduced. Waste concrete is fully utilized as recycled aggregate, and application and popularization of the recycled concrete in building foundation engineering are facilitated.
