Steel pipe concrete pile
The invention provides a steel pipe concrete pile. The steel pipe concrete pile comprises an outer-layer steel pipe; a spiral rib is fixed on the inner wall of the outer-layer steel pipe; a plurality of circles of rivets are fixed at the circumference of the inner wall of the outer-layer steel pipe; the outer-layer steel pipe is lined with a concrete inner layer, and an end plate is arranged at the end portion of the outer-layer steel pipe; according to the structural design, the biting force of the steel pipe and the concrete comprises three parts, namely the biting force of the spiral rib and the concrete, the anchoring force of the rivet and the concrete and the binding force of the inner wall of the steel pipe and the concrete; the added spiral rib rivet is capable of improving the binding of the concrete and the steel pipe to a large extent, so that the concrete and the steel pipe can be bound firmly and the impact resistance can be enhanced, and in the striking process, the concrete and the steel pipe are not separated from each other. According to experimental verification, after the spiral rib is added and the rivet is arranged, the bending resistance and the shear-bearing capacity of the novel pipe pile are improved by 50%.
