Prestressed concrete pipe pile
The invention relates to a prestressed concrete pipe pile which comprises concrete and a reinforcement cage, the reinforcement cage is fixed in the concrete, and the reinforcement cage comprises longitudinal prestressed reinforcements, supporting reinforcements, first spiral stirrups and second spiral stirrups; the supporting reinforcing steel bars are of a closed annular structure, the longitudinal prestressed reinforcing steel bars are fixed in the circumferential direction of the supporting reinforcing steel bars, the prestressed reinforcing steel bars are located in the supporting reinforcing steel bars, and the longitudinal prestressed reinforcing steel bars and the supporting reinforcing steel bars form a foundation reinforcing steel bar cage. The first spiral stirrup is fixed to the foundation reinforcement cage in a surrounding mode downwards from the highest point of the back face of the foundation reinforcement cage in the first hour hand direction, the second spiral stirrup is fixed to the foundation reinforcement cage in a surrounding mode downwards from the highest point of the front face of the foundation reinforcement cage in the first hour hand direction, and the first hour hand direction is opposite to the second hour hand direction. Compared with the prior art, the invention has the advantages of high bearing capacity, wide application range and the like.
本发明涉及一种预应力混凝土管桩，包括混凝土和钢筋笼，所述钢筋笼固定在混凝土的内部，所述钢筋笼包括纵向预应力钢筋、支撑钢筋、第一螺旋箍筋和第二螺旋箍筋；所述支撑钢筋为封闭环状结构，所述纵向预应力钢筋沿支撑钢筋周向固定，所述预应力钢筋位于支撑钢筋的内部，所述纵向预应力钢筋和支撑钢筋构成基础钢筋笼；所述第一螺旋箍筋由基础钢筋笼背面的最高点向下沿第一时针方向环绕固定在基础钢筋笼上，所述第二螺旋箍筋由基础钢筋笼正面的最高点向下沿第一时针方向环绕固定在基础钢筋笼上，所述第一时针方向与第二时针方向相反。与现有技术相比，本发明具有承载能力强、适用范围广等优点。
