Setting type bridge deepwater foundation and construction method thereof
The invention relates to a set-type bridge deepwater foundation and a construction method thereof, and belongs to the technical field of bridge foundation engineering. The set-type bridge deepwater foundation comprises an open caisson, and the open caisson is arranged in an underwater foundation soil layer; the foundation is arranged on the bottom surface of the foundation pit in the open caisson, and a pier column used for supporting a bridge is connected to the foundation; the energy dissipation pool is a space defined by the inner wall of the open caisson, the top face of the foundation and the outer wall of the pier column. The open caisson plays a supporting role in the excavation process of the foundation pit, the feasible excavation depth of the foundation pit is increased, and therefore the burial depth of the foundation can be increased, the bearing capacity of the foundation is improved, the settlement amount of the foundation after construction is reduced, and the risk that foundation soil is scoured and elutriated by water flow is reduced. The energy dissipation pool is used for weakening the scouring effect of water flow on the peripheral foundation of the foundation, can prevent horseshoe-shaped vortexes at the bottom of the pier from diffusing to the peripheral soil body of the foundation, effectively protects the peripheral soil body of the foundation from being scoured by horseshoe-shaped vortex water flow, and indirectly further enhances the anti-scouring performance of the foundation.
本申请涉及一种设置式桥梁深水基础及其施工方法，属于桥梁基础工程技术领域，包括沉井，所述沉井设置在水下的地基土层内；基础，所述基础设置所述沉井内的基坑底面上，所述基础上连接有用于支撑桥梁的墩柱；消能池，所述消能池为沉井内壁、基础顶面和墩柱外壁围成的空间。所述沉井在基坑开挖过程中起支护作用，使可行的基坑开挖深度增加，因此可以增大设置基础的埋深，从而使地基承载力提高、基础工后沉降量减小、地基土被水流冲刷淘蚀的风险降低。所述消能池用于削弱水流对基础周边地基的冲刷作用，能阻止墩底马蹄形漩涡向基础周边土体扩散，有效保护基础周边土体免遭马蹄形漩涡水流的冲刷作用，间接地进一步增强基础抗冲刷性能。
