Large-diameter PHC tubular pile with double-layer reinforcement cage and preparation method thereof
The invention discloses a large-diameter PHC tubular pile of a double-layer reinforcement cage and a preparation method thereof, and relates to the technical field of PHC tubular piles. According to the large-diameter PHC tubular pile, the PHC tubular pile is optimized in the mode that ordinary steel bars and prestressed steel bars are combined and configured, a plurality of ordinary steel bars are arranged in a high-strength concrete pile body and are close to the outer side wall, a plurality of prestressed steel bars are arranged in the high-strength concrete pile body and are close to the inner side wall, the steel bars which are enclosed into a triangle are welded to the prestressed steel bars in the corresponding positions, and the angular points of the triangular steel bars are bound and connected with the ordinary steel bars in the corresponding positions. In the mode, on one hand, the maximum bending resistance and shearing resistance of the pile body are increased, and on the other hand, the pile body has certain energy dissipation capacity, namely certain ductility performance, so that under the action of horizontal cyclic loads, the pile body can have enough deformation to consume more energy, and brittle failure is avoided. The large-diameter PHC tubular pile has the characteristics of convenience in manufacturing, economy, reliability and high practicability, and the anti-seismic performance of the high-strength prestressed tubular pile is improved.
一种双层钢筋笼的大直径PHC管桩及其制备方法，涉及PHC管桩技术领域。本发明采用普通钢筋与预应力钢筋结合配置的方式来优化PHC管桩，数根普通钢筋设置在高强混凝土桩身内靠近外侧壁处，数根预应力钢筋设置在高强混凝土桩身内靠近内侧壁处，将围成三角形的钢条焊接在对应位置的预应力钢筋上，三角形的钢条的角点与对应位置的普通钢筋绑扎连接。通过上述方式一方面提高桩身的抗弯抗剪的最大能力，另一方面使桩身具有一定的耗能能力，即具有一定的延性性能，以使得在水平循环荷载作用下，桩身可以有足够的变形来消耗更多能量，避免脆性破坏。本发明具有制作方便，经济可靠，实用性强的特点，实现了对高强预应力管桩抗震性能的提升。
