Anti-scouring structure for bridge high pile cap foundation
The invention relates to an anti-scouring structure for a bridge high-pile bearing platform foundation. The high-pile bearing platform foundation comprises a bearing platform and a pile group connected with the bearing platform, and the pile group comprises a plurality of pile foundations; the anti-scouring structure comprises a pile front water baffle used for being connected with the bearing platform, and the pile front water baffle faces the incident flow side of the bearing platform; the pile front water collecting pipe is fixedly connected with the pile front water baffle; the pre-pile sand collecting tank is movably connected with the pre-pile water collecting pipe; and the sand collecting protection ring is used for being arranged on the pile foundation in a sleeving mode. According to the anti-scouring structure for the high-pile bearing platform foundation of the bridge, on the basis of the scouring mechanism of the high-pile bearing platform foundation, the step-by-step progressive and mutually-combined turbulent flow siltation promotion anti-scouring effect is achieved through the pile-front water baffle, the pile-front water collecting pipe, the pile-front sand collecting groove and the sand collecting protective ring. Different from a riprap protection measure which is taken only when a pier scouring pit is formed and threatens bridge safety, silt is actively supplemented and collected to ensure that the silt on the original bed surface in the pile foundation is not scoured away as far as possible, the pile body is not damaged, and regular sweeping, measuring and maintaining are not needed.
本申请涉及一种用于桥梁高桩承台基础的防冲刷结构，高桩承台基础包括承台、与承台连接的群桩，群桩包括多个桩基；防冲刷结构包括：桩前挡水板，用于与承台连接，桩前挡水板面向承台的迎流侧；桩前集水管，与桩前挡水板固定连接；桩前集沙槽，与桩前集水管活动连接；集沙护圈，用于套设在桩基上。本发明提供一种用于桥梁高桩承台基础的防冲刷结构，基于高桩承台基础的冲刷机理，通过桩前挡水板、桩前集水管、桩前集沙槽和集沙护圈发挥逐级递进且相互联合的扰流促淤防冲刷作用。不同于桥墩冲刷坑已经形成且威胁桥梁安全时才采取的抛石防护措施，本申请主动补集泥沙以保证桩基内部原床面泥沙尽可能不被冲刷带走，不会损坏桩体，也无需定期扫测维护。
