Replaceable pier anti-explosion device suitable for circular-section pier and mounting method thereof
The invention discloses a replaceable pier anti-explosion device suitable for a pier with a circular section and an installation method of the replaceable pier anti-explosion device. The replaceable pier anti-explosion device is composed of a foam concrete filled honeycomb energy dissipation core layer, an explosion facing panel, connecting pieces and bolts. Wherein the core layer is composed of four quarter ring foam concrete filled honeycomb composite boards, and the core layer and the panels are connected into a closed ring whole through bolts and connecting pieces. The invention further provides a mounting method of the bridge pier anti-explosion device, the bridge pier anti-explosion device is suitable for anti-explosion protection of the bridge pier with the circular section, in theexplosion process, the panel can enable a certain number of explosion waves to be diffracted, the core layer can be evenly compressed, and energy absorption of the core layer is brought into full play. The core layer absorbs explosion energy through compression, and energy and peak load transmitted to the pier are reduced. And the damaged part of the device in explosion can be directly replaced, so that the time cost and the economic cost of pier maintenance are remarkably reduced.
本发明公开了一种适用于圆形截面桥墩的可替换桥墩抗爆装置及其安装方法，由泡沫混凝土填充蜂窝耗能芯层、迎爆面板、连接件及螺栓组成。其中芯层由四块四分之一圆环泡沫混凝土填充蜂窝组合板组成，通过螺栓及连接件将芯层和面板连接成一个封闭圆环整体。本发明还提供了上述装置的安装方法，本发明提供的桥墩抗爆装置适用于圆形截面桥墩的抗爆防护，在爆炸中，面板可使一定数量爆炸波发生绕射，且可使芯层均匀压缩，充分发挥其吸能。芯层通过压缩吸收爆炸能量，降低传递给桥墩的能量和峰值荷载。可直接对爆炸中装置损坏的部分进行替换，显著降低了桥墩维修的时间成本和经济成本。
