Filling pipe and anti-collision equipment
The invention provides a filling pipe and anti-collision equipment, the anti-collision equipment is formed by connecting a plurality of sections of filling pipes end to end and surrounds a bridge pier column, each filling pipe comprises a shell, a framework and energy dissipation units, the framework is covered with the shell and welded with the shell, a plurality of tubular energy dissipation units are arranged in the framework, and gaps exist between the energy dissipation units. The shell deforms to push the annular reinforcing ribs of the framework to cut the energy dissipation unit, so that the energy dissipation unit becomes a multi-section cylinder, part of impact kinetic energy is consumed in the cutting process, and the energy dissipation unit rolls, misplaces and deforms step by step after absorbing the impact kinetic energy, continues to consume the impact kinetic energy and finally absorbs all the impact kinetic energy, so that impact is stopped. Sectional type energy dissipation can be achieved, the anti-collision equipment cannot become an elastic body all the time in the collision process by setting the clearance rate of the internal energy dissipation units, the whole anti-collision equipment has the bearing capacity, an energy absorption curve is relatively stable, and a bridge and a ship can be effectively protected.
本发明提供了一种填充管及防撞设备，防撞设备由多段填充管首尾连接制成，环绕在桥墩柱周围，填充管包括外壳，骨架和消能单元，外壳覆盖在骨架上，与骨架焊接，骨架内置入多个管状消能单元，消能单元之间存在间隙，当船舶撞击发生时，外壳变形推动骨架的环向加强筋切割消能单元，使消能单元变成多段圆柱体，切割过程中消耗一部分撞击动能，消能单元吸收撞击动能后滚动错位并逐步变形，继续消耗撞击动能，最终吸收所有撞击动能，使撞击停止。本发明能够实现分段式耗能，通过设置内部的消能单元的间隙率使防撞设备在撞击过程中始终不会变成弹性体，整个防撞设备有承载能力，吸收能量的曲线相对平稳，能有效的保护桥梁和船舶。
