Deepwater pile group foundation reinforcement cage and design method thereof
The invention relates to the technical field of bridge engineering, in particular to a deepwater pile group foundation reinforcement cage and a design method thereof.The deepwater pile group foundation reinforcement cage comprises a plurality of vertical main reinforcements, a plurality of horizontal main reinforcements and a plurality of horizontal main reinforcements, the standard sections of the multiple vertical main reinforcements are used for being annularly and evenly arranged at intervals with the center of the section of the pile foundation as the circle center, and the anchoring sections corresponding to the standard sections are located above the top face of the pile foundation and used for being arranged in the nearest gap in a plurality of gaps defined by longitudinal horizontal reinforcements and transverse horizontal reinforcements which are evenly arranged at set intervals at the bottom face of a bearing platform in a penetrating mode. The transition section is located between the corresponding standard section and the anchoring section and is bent by a set angle relative to the standard section and the anchoring section. The problems that in the prior art, the construction difficulty is large when horizontal steel bars on the bottom face of a bearing platform penetrate through the range of a pile foundation steel reinforcement cage, the spacing density of the horizontal steel bars is uneven, and concrete is difficult to pour densely due to the fact that vibration cannot be conducted on the area with dense spacing are solved.
本发明涉及桥梁工程技术领域，具体涉及一种深水群桩基础钢筋笼及其设计方法，该深水群桩基础钢筋笼包括：多根竖向主筋，每一竖向钢筋均包括标准段、渐变段和锚固段，多根竖向主筋的标准段用于以桩基截面中心为圆心环向均匀间隔设置，标准段对应的锚固段位于桩基顶面以上，用于穿设在由按设定间距均匀间隔设置的承台底面纵向水平钢筋和横向水平钢筋围成的多个空隙中最近的空隙内，渐变段位于对应标准段和锚固段之间，并相对于标准段和锚固段弯折设定角度。能够解决现有技术中承台底面水平钢筋穿过桩基钢筋笼范围施工难度大，以及水平钢筋的间距疏密不均，间距较密的区域由于无法振捣，混凝土很难浇筑密实的问题。
