Description

Technical Field

[0001] The utility model belongs to the technical field of concrete pipe piles, and particularly relates to a skeleton-reinforced concrete pipe pile. Background Art

[0002] Concrete pipe piles are generally composed of a steel cage and concrete that wraps the steel cage. The steel cage is generally made of steel bars, and together with the concrete, it forms a reinforced concrete structure to form a concrete pipe pile with high structural strength and long service life. The existing steel cage includes main bars arranged in an annular shape and spiral bars wound around the main bars. The main bars are made of large-diameter deformed bars, and the spiral bars are made of ordinary bars with smaller diameters. The spiral bars and the main bars are also tied or welded together by wires or the like to maintain the shape of the steel cage. The inside of the existing steel cage is hollow and generally filled with concrete directly. Such pipe piles can only meet the structural strength requirements of general pipe piles. For high-strength large-diameter and large-length pipe piles, this type of steel cage structure is difficult to meet the performance requirements. By sleeving a small steel cage inside the steel cage or other methods, the structural strength of the steel cage can be enhanced, but the cost of the pipe pile will increase significantly. Therefore, it is necessary to design a new type of concrete pipe pile that can enhance the structural strength of the pipe pile without significantly increasing the material cost.
