Prestressed concrete cast-in-place pile with high bearing capacity
The invention discloses a prestressed concrete cast-in-place pile with high bearing capacity, which is vertically put in a drill hole and comprises two annular steel plates which are vertically distributed, a plurality of rubber sleeves which are connected between the two steel plates, a plurality of rubber sleeves which are annularly distributed, and prestressed tendons which penetrate through the rubber sleeves and the steel plates at the two ends, the top of the rubber sleeve is further connected with a prestressed grouting pipe extending upwards, and the prestressed tendons and the steel plate are fixed through anchoring clamping pieces. Stirrups are fixedly wound on the outer sides of the multiple rubber sleeves, a plurality of stiffening hoops are fixedly installed on the inner sides of the multiple rubber sleeves in the length direction of the isolation pipe, concrete is poured between the two steel plates, and when the concrete reaches the design strength, the prestressed tendons are tensioned, and grouting is conducted in the rubber sleeves through the prestressed grouting pipe. Prestress is evenly applied to the steel plates at the two ends, the structure is simplified, cost is reduced, and the prestress effect is improved.
本发明公开了一种高承载力的预应力混凝土灌注桩，垂直投放于钻孔中，包括：垂直分布的两个呈环状的钢板，连接于两个钢板间的若干橡胶套管，若干橡胶套管呈环状分布，穿设于橡胶套管以及两端钢板的预应力筋，橡胶套管顶部还连接有向上延伸的预应力注浆管，预应力筋与钢板间通过锚固夹片固定；若干橡胶套管外侧固定绕设有箍筋以及内侧沿隔离管长度方向固定安装有多个加劲箍，两个钢板间灌注混凝土，混凝土达到设计强度时，对预应力筋张拉并经预应力注浆管向橡胶套管内注浆，本发明将预应力筋替代传统钢筋笼内的纵筋，预应力均匀的施加在两端钢板上，简化了结构，降低了成本，提高了预应力效果。
