PHC tubular pile with pre-embedded steel bar-FRP double-layer reinforcement cage and preparation method of PHC tubular pile
The invention discloses a PHC tubular pile with a pre-embedded steel bar-FRP double-layer reinforcement cage and a preparation method of the PHC tubular pile, and belongs to the technical field of civil engineering. The PHC tubular pile comprises a high-strength concrete pile body with a cavity, wherein a FRP pipe is fixedly arranged on the outer surface of the high-strength concrete pile body in a sleeving mode, and the steel bar-FRP double-layer reinforcement cage is arranged in the high-strength concrete pile body. The method comprises the following steps that the FRP reinforcement cage is manufactured; a prestressed steel bar cage and the FRP reinforcement cage are bound or welded to form a steel bar-FRP double-layer reinforcement cage, the FRP pipe is positioned, and the steel bar-FRP double-layer reinforcement cage is placed in the FRP pipe; a cylindrical mold is supported on the inner side of the steel bar-FRP double-layer reinforcement cage, high-strength concrete is poured between the cylindrical mold and the FRP pipe, and a PHC pipe pile blank of the pre-embedded steel bar-FRP double-layer reinforcement cage is manufactured; and the blank is put into a standard curing room to be cured, demolding is conducted after curing is completed, and the PHC pipe pile with the pre-embedded steel bar-FRP double-layer reinforcement cage is manufactured. The PHC tubular pile has large horizontal and vertical bearing capacity, and the requirement for huge horizontal thrust generated by earthquake loads, typhoons, waves and the like is met.
一种预埋钢筋‑FRP双层筋笼的PHC管桩及其制备方法，属于土木工程技术领域。本发明的PHC管桩，包括具有空腔的高强混凝土桩身；FRP管固定套设在所述高强混凝土桩身的外表面，钢筋‑FRP双层筋笼设置在高强混凝土桩身的内部。方法是：制作FRP筋笼；将预应力钢筋笼与FRP筋笼绑扎或焊接形成钢筋‑FRP双层筋笼，定位FRP管，将钢筋‑FRP双层筋笼放置在FRP管内；在钢筋‑FRP双层筋笼内侧支圆筒状模具，在圆筒状模具与FRP管之间浇筑高强混凝土，制成预埋钢筋‑FRP双层筋笼的PHC管桩毛坯；将毛坯放入标准养护室内养护，养护完成，脱模，即制成预埋钢筋‑FRP双层筋笼的PHC管桩。本发明的PHC管桩具有较大的水平及竖向承载力，满足地震荷载、台风和波浪等产生的巨大水平推力。
