Pre-tensioning method prestressed concrete bilateral imitation wood pile
The invention relates to a pre-tensioning method prestressed concrete bilateral imitation wood pile. The pile comprises at least six prestressed steel bars and a plurality of pile bodies, wherein the prestressed steel bars are arranged along spiral stirrups at equal intervals; the spiral stirrup is arranged on the periphery of the prestressed reinforcement in a sleeving manner; the pile is hooped; the pile hoop is arranged on the periphery of the spiral stirrup, and a circular pile main body cavity is defined by the pile hoop; and the end plates are arranged at the two ends of the prestressed steel bars. The prestressed reinforcement is a steel bar for prestressed concrete, and the diameter of the steel bar is not less than 7.1 mm; an inner hole of the end plate is a round hole; wing edges are symmetrically arranged on the two sides of the end plate, and tongue-and-grooves are formed in the wing edges on the two sides; the rabbet on one side is a concave arc, and the rabbet on the other side is a convex arc. The precast pile and the end plate matched with the precast pile are reasonable in structure, attractive in appearance and large in soil retaining width; the high-strength steel bars are adopted to replace common steel bars, the steel consumption is reduced under the condition that the same stress requirement is met, and resources are further saved.
本发明涉及一种先张法预应力混凝土双边仿木桩，包括：至少6根预应力钢筋：预应力钢筋沿螺旋箍筋等距设置；螺旋箍筋：螺旋箍筋套设于预应力钢筋的外周；桩套箍；桩套箍设置于螺旋箍筋的外周，桩套箍围设形成圆桩主体腔；端板：端板设置于预应力钢筋的两端。预应力钢筋为直径不小于7.1mm的预应力混凝土用钢棒；端板的内孔为圆孔；端板两侧设有对称布置的翼边，两侧翼边均设有企口；一侧企口为内凹的圆弧，另一侧企口为外凸的圆弧。本发明预制桩和该预制桩相匹配的端板结构合理、造型美观、挡土宽度大；采用高强钢棒代替普通钢筋，达到同等受力要求的条件下，用钢数量降低，进一步节约资源。
