摘要
The invention above which the structure load operating much in the pile foundation is to improve the upper steel tube inside the cross-section resistance as composed of a high steel pipe pile (4) cross-sectional resistance, and the lower part consists of a concrete low material cost hollow peg (20) internal filling and pouring concrete for hollow concrete piles in the pile synthesis of high temperature curing;; Hollow concrete piles a small hole 41 in the in the continuous blockage steel cover plate central portion of using the stopper 40, after the first by a perforated cover plate 39 by welding, and making the hollow concrete pile small hole 41, the joint of steel pipe pile with a hollow concrete piles after film and relates to a construction method of the synthetic pile to pouring concrete therein;; While due to the continuous steel cover plate improves the economics by reducing the concrete amount to be poured on-site prevent the concentration of stress occurring in concrete and to prevent deterioration of the concrete pile member by the expansion and contraction of the internal air of the high temperature curing of the hollow concrete It may be, there is an effect such that the construction is easy to minimize the field.
