Pile foundation capable of controlling horizontal deformation and construction method
The invention discloses a pile foundation capable of controlling horizontal deformation and a construction method. The pile foundation capable of controlling horizontal deformation comprises an inner side pile casing, and the inner side of the inner side pile casing is used for construction; the outer side pile casing is arranged outside the inner side pile casing in a sleeving manner, and a gap is formed between the outer side pile casing and the inner side pile casing; the elastic layer is arranged in the interval, the elastic layer is fixedly connected to the inner side of the outer side pile casing, and the elastic layer can be separated from the inner side pile casing; the bottom plate is used for bearing the bottoms of the inner side pile casing and the outer side pile casing; the limiting device connects the inner side pile casing with the outer side pile casing, and the limiting device can adjust the size of the interval between the inner side pile casing and the outer side pile casing based on the flexibility of the elastic layer. The elastic layers are arranged on the inner side pile casing and the outer side pile casing, the inner side of the inner side pile casing is used for construction and can be separated, so that the pile foundation can be properly deformed, constraint to a pier column is reduced, overall stress of upper and lower structures is improved, horizontal displacement of the pile foundation is controlled through the limiting device, and the horizontal deformation requirements of different pile foundations are met; the method has good adaptability.
本发明公开了一种可控水平变形的桩基础及施工方法，可控水平变形的桩基础包括内侧护筒，内侧护筒的内侧用于施工；外侧护筒套设在内侧护筒外，外侧护筒与内侧护筒之间具有间隔；弹性层设置间隔内，弹性层固定连接于外侧护筒的内侧，且弹性层与内侧护筒可分离；底板用于承载内侧护筒和外侧护筒的底部；限位装置将内侧护筒和外侧护筒相互连接，限位装置能够基于弹性层的柔性而调节内侧护筒和外侧护筒之间的间隔大小。通过弹性层设置在内侧护筒和外侧护筒，内侧护筒内侧用于施工且可分离，使得桩基础能够适当变形减少了对墩柱的约束，改善上下部结构整体受力，通过限位装置控制桩基础的水平位移，满足不同桩基础的水平变形要求，具有良好的适应性。
