The invention relates to a pre-stressed concrete pipe pile. The pre-stressed concrete pipe pile is composed of a pile body. Convex rib grains or convex movable expanding fins are arranged on the outercircumferential wall of the pile body. The rib grains are rectangular strip-shaped bodies which are spirally distributed in a spaced mode. The ribs are equal-height ribs which are arranged in a spaced mode. The rib grains are crescent ribs which are obliquely arranged in a spaced mode, and the crescent ribs are mutually independent. Pre-stressed steel formworks are arranged in the pile body in aspaced mode, and the pile body is cylindrical or square. The friction coefficient between the pre-stressed concrete pipe pile and a foundation soil layer can be greatly increased; and the pre-stressedconcrete pipe pile has the advantages of being simple in structure, high in bearing capacity, free of settlement, capable of saving labor and time, and capable of guaranteeing a long service life ofbuildings.
本发明属于一种预应力混凝土管桩，由桩体所组成，桩体的外周壁上设有凸出的肋纹或凸出的活动外胀翅。所述的肋纹为呈间隔距离螺旋状分布的矩形条状体。所述的肋纹为呈间隔距离设置的等高肋体。所述的肋纹为呈间隔距离设置的月牙肋体，月牙肋体斜向设置，月牙肋体彼此独立设置。所述的桩体内呈间隔距离设有预应力钢筋骨架，桩体呈圆形体，或呈方形体。本发明能大幅度地提高混凝土管桩与地基土层的磨擦系数，具有结构简单，管桩承托力强，无沉降，施工省工省力，建筑物使用寿命长的优点。
