Multi-bridge shared pier with intelligent prestress system
The invention relates to the technical field of roads and bridges, and discloses a multi-bridge shared pier with an intelligent prestress system, which comprises a variable cross-section stepped pier stud vertically and fixedly connected with a foundation, capping beam components are respectively arranged at the top and the cross section change position of the pier stud, and the intelligent prestress system extending along the axial direction is arranged in the pier stud, the upper end penetrates out of the top face of the pier stud and is arranged in a bent cap assembly at the top of the pier stud, the lower end penetrates out of the bottom face of the pier stud and is arranged in a foundation, and sensing assemblies in signal connection with an intelligent prestress system are arranged at the bottom and section changing positions of the pier stud. The multiple bent cap assemblies are arranged, multiple purposes are achieved through one pier, and therefore the occupied space is reduced, the construction cost is reduced, and crowding caused by too many piers is avoided; an intelligent prestress system is arranged in the pier column, the internal stress state of the pier can be optimized when the pier bears eccentric loads, it is guaranteed that the pier is always in a small eccentric compression state, powerful guarantee is provided for structural safety, and the pier has great popularization value and wide application prospects.
本发明涉及道路桥梁技术领域，公开了一种设有智能预应力系统的多桥共用桥墩，包括与基础竖直固接的变截面阶梯形的墩柱，墩柱顶部和截面变化位置分别设有盖梁组件，墩柱中设有沿轴向延伸的智能预应力系统，且上端穿出墩柱顶面并置于墩柱顶部的盖梁组件中，下端穿出墩柱底面并置于基础中，墩柱底部和截面变化位置设有与智能预应力系统信号连接的传感组件。设置多个盖梁组件，实现“一墩多用”，从而缩小占地空间、缩减建设成本，避免因桥墩过多造成的拥挤；墩柱中设置智能预应力系统，还能优化桥墩在承受偏心载荷时内部的受力状态，保证桥墩始终处于小偏心受压的状态，为结构安全提供强有力的保障，具有极大的推广价值和广阔的应用前景。
