Underwater pile foundation for bridge
The invention discloses an underwater pile foundation for a bridge. The underwater pile foundation comprises a pile foundation body, and the pile foundation body is configured to be of a structure with a polygonal section; the pile foundation base is located at the lower end of the pile foundation body, and at least part of the pile foundation base is buried under the water ground; the pile foundation base is provided with a pre-embedded assembly, and the pile foundation base is connected with a ground base layer through the pre-embedded assembly; the section size of the pile foundation base is larger than that of the pile foundation body. A reinforcement cage structure is arranged in the pile foundation body and is divided into a plurality of reinforcement layers, and each reinforcement layer is of a double-layer structure in the circumferential direction of the pile foundation body. The internal reinforcement cage of the underwater pile foundation is of a double-layer structure, the structural strength of the reinforcement cage is improved through the reinforcement layer of the double-layer structure and the inner-layer reinforcement and the outer-layer reinforcement of the double-layer structure, corners are eliminated through the outer-layer reinforcement layer of the inequilateral octagon to form an inclined plane, and it is guaranteed that the reinforcement cage is of an approximately cuboid structure; and the impact resistance of the corner is improved through the inclined plane.
本发明公开了一种桥梁用水下桩基，包括桩基本体，桩基本体被配置为截面为多边形的结构；位于桩基本体下端的桩基底座，桩基底座至少部分埋设于水下地面以下；桩基底座具有预埋组件，桩基底座通过预埋组件形成于地面基层的连接；桩基底座的截面尺寸大于桩基本体的截面尺寸；桩基本体内部具有钢筋笼结构，钢筋笼结构分为多层钢筋层，且每层钢筋层沿桩基本体的周向方向均设置为双层结构。本发明的水下桩基内部钢筋笼为双层结构，以双层结构的钢筋层和双层结构的内层钢筋和外层钢筋提高钢筋笼的结构强度，并通过不等边的八边形外层钢筋层消除了转角以形成斜面，保证了大体为长方体结构的同时，通过斜面提高转角的抗冲击能力。
