Mountainous area bridge water curtain debris flow anti-collision device and method
The invention discloses a mountainous area bridge water curtain debris flow anti-collision device and method, which can deflect the movement direction of debris flow, prevent the debris flow from directly impacting and damaging a bridge abutment, and ensure the structural safety of the bridge abutment. The device comprises bridge abutments, an anti-collision pier is vertically arranged on the upstream side of the bridge abutments, the cross section of the anti-collision pier is in an isosceles triangle shape, the bottom edge of the isosceles triangle is parallel to a bridge, the vertex angle of the isosceles triangle is opposite to the bridge, and water curtain spray heads are arranged on the vertex angle edge and the two side faces of the anti-collision pier. After debris flow outbreaks,the mud position is gradually increased to the water curtain starting mud position, a mud position sensor transmits mud position information to an intelligent starting and stopping device, the intelligent starting and stopping device is automatically started, and a water curtain is formed at each water curtain spray head. After the water curtains are formed, a reverse load is applied to an incoming debris flow body, the debris flow is forced to deflect towards the two sides and pass through the bridge from the position between the bridge abutments, and the bridge abutments are prevented from being impacted and damaged by the debris flow.
本发明公开了一种山区桥梁水幕泥石流防撞装置及方法，本发明能够使泥石流运动方向偏转，避免泥石流对桥梁墩台的直接冲击破坏，确保桥梁墩台结构安全。包括桥梁墩台，桥梁墩台的上游侧立设有防撞墩，防撞墩的横截面呈等腰三角形，等腰三角形的底边与桥梁平行，等腰三角形的顶角背向桥梁，防撞墩的顶角棱边上以及两侧面上均设有水幕喷头。泥石流爆发后，泥位逐渐提高至水幕启动泥位，泥位传感器将泥位信息传递到智能启停装置，智能启停装置自动开启，在各水幕喷头处形成水幕；水幕形成后，对到来的泥石流体施加反向荷载，迫使泥石流流向两侧发生偏转，并从桥梁墩台之间通过桥梁，使桥梁墩台不被泥石流冲击破坏。
