Combined flexible extension energy dissipation pier protection structure
The invention provides a combined flexible extension energy dissipation pier protection structure. The invention belongs to the field of road-bridge traffic safety facilities. The structure comprisesa bridge pier body, an external anti-collision outer wrapping cushion structure, an upper connecting sealing plate, a lower connecting sealing plate, an outer wrapping large-caliber fixed connecting steel cylinder, an internal small-caliber fixed connecting steel cylinder, a ring fixed connecting steel rib plate, a flexible extension energy dissipation connecting lead ring and a lead ring tightening ring fixed connecting piece. The built-in small-caliber fixedly-connected steel cylinder is arranged on the outer ring of the pier. And the outer layer of the built-in small-caliber fixedly-connected steel cylinder is provided with the outer wrapping large-caliber fixed connecting steel cylinder. The pier protection structure has the beneficial effects that a large amount of low-yield-point steel and the flexible extension energy dissipation connecting lead ring are adopted, the energy dissipation capacity, the damping effect and the ductility of the anti-collision system can be improved, the cost is low, manufacturing is easy, and good economic benefits are achieved.
本发明提供一种组合式柔性延展耗能桥墩保护结构，属于路桥交通安全设施领域，包括桥墩、外置防撞外包垫结构、上连接封板、下连接封板、外包大口径固定连接钢筒、内置小口径固定连接钢筒、环圈固定连接钢肋骨板、柔性延展耗能连接铅环、铅环紧箍固定连接件，桥墩的外圈设置内置小口径固定连接钢筒，内置小口径固定连接钢筒的外层设置外包大口径固定连接钢筒，本发明的有益效果是采用大量低屈服点钢材和柔性延展耗能连接铅环能增大防撞体系耗能能力、阻尼效果和延性能力，成本低，制作简单，具有良好的经济效益。
