The invention belongs to the technical field of engineering construction, and particularly relates to a corrosion-resistant pre-stressed concrete tubular pile. The corrosion-resistant pre-stressed concrete tubular pile comprises a pile body, wherein a blind hole is formed in the pile body; a group of grouting holes is uniformly formed in the periphery in the vertical direction of the side wall ofthe pile body, and a steel rope is arranged in the grouting holes; a circular disc is arranged on the bottom of the pile body, and a transverse slide slot is formed in the circular disc; one end of the slide slot communicates with the outside; an anchor rod is connected in the slide slot in a sliding mode; and the lower end of the steel rope is fixedly connected to the tail part of the anchor rod.According to the corrosion-resistant pre-stressed concrete tubular pile disclosed by the invention, a piling machine punches the pile body into sludge on the bottom of seawater; while the pile body reaches a predetermined position, the steel rope is stretched and drawn by hydraulic equipment; after the steel rope is tightened, the anchor rod is driven to extend out towards the outer side of the pile body; under driving of tensile force of the steel rope, the anchor rod is inserted into a soil layer near the pile body to increase friction force between a vertical stress area of the pile body and the soil layer, so that bearing ability of the pile body is increased; and then, high-pressure concrete is filled into the grouting holes, so that the steel rope is fixed, and therefore, strength of the pile body is further strengthened.
本发明属于工程建设技术领域，具体的说是一种耐腐蚀的预应力混凝土管桩，包括桩身；桩身内设有盲孔，桩身侧壁竖直方向圆周均布一组灌浆孔，灌浆孔中设有钢索；桩身底部设有圆盘，圆盘中开设有横向布置的滑槽，滑槽一端与外界连通，滑槽中滑动连接有锚杆；钢索下端与锚杆尾部固连；本发明通过打桩机将桩身打入海水底部的淤泥中，当桩身到达预定位置后，通过液压设备对钢索进行张拉，钢索收紧后带动锚杆向桩身外侧伸出，锚杆在钢索的拉力带动下插入桩身附近的土层中，增大桩身的竖向受力面积和与土层的摩擦力，进而增加桩身的承载能力，之后向灌浆孔中灌注高压混凝土，进而对钢索进行固定，进一步增加桩身的强度。
