UHPC (Ultra High Performance Concrete) reinforced pile foundation and reinforcing method thereof
The invention discloses a UHPC (Ultra High Performance Concrete) reinforced pile foundation and a reinforcing method thereof. The reinforcing method comprises the following steps: S1, manufacturing a circular steel casing; s2, the first pile casing and the second pile casing are assembled into a circular steel pile casing, and the circular steel pile casing is statically pressed outside the pile foundation; s3, the area between the pile foundation and the circular steel casing is washed, so that a cavity is formed between the pile foundation and the circular steel casing, and the concrete aggregate is exposed out of the pile foundation; s4, a circular reinforcement cage is manufactured, and the circular reinforcement cage is placed in a cavity between the pile foundation and the circular steel casing; and S5, pouring UHPC (Ultra High Performance Concrete) by taking the circular steel casing as a template. The circular steel casing is arranged outside the pile foundation, flushing and desilting are carried out between the pile foundation and the circular steel casing to form the cavity, the circular reinforcement cage is placed in the cavity, and the UHPC is poured to serve as the added structural section of the pile foundation, so that the construction method has the advantages of being large in bending and shearing resistance rigidity, high in bearing capacity, good in durability and the like, and is short in construction period and good in reinforcement effect.
本发明公开了一种UHPC加固桩基及其加固方法，包括：步骤S1：制作圆形钢护筒；步骤S2：将第一护筒和第二护筒拼装成圆形钢护筒，将圆形钢护筒静压在桩基外；步骤S3：对桩基与圆形钢护筒之间的区域进行冲洗，使桩基与圆形钢护筒之间形成空腔，桩基露出混凝土骨料；步骤S4：制作圆形钢筋笼，将圆形钢筋笼放置到桩基与圆形钢护筒之间的空腔内；步骤S5：以圆形钢护筒为模板浇筑UHPC超高性能混凝土。通过将圆形钢护筒设置在桩基外，对桩基与圆形钢护筒之间进行冲洗除泥形成空腔，将圆形钢筋笼放置在空腔内，浇筑UHPC超高性能混凝土作为桩基增加的结构截面，具有抗弯剪刚度大、承载能力强、耐久性好等优点，施工周期短，加固效果好。
