摘要：【中文】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。 【EN】The invention discloses a mountainous bridge water curtain debris flow anti-collision device and method, which can deflect the movement direction of debris flow, avoid the direct impact damage of the debris flow to a bridge abutment and ensure the safety of the bridge abutment structure. Including the bridge pier, the upper reaches side of bridge pier is equipped with crashproof mound immediately, and isosceles triangle is personally submitted in crashproof mound's transversal, and isosceles triangle's base is parallel with the bridge, and isosceles triangle's apex angle is the bridge dorsad, all is equipped with the water curtain shower nozzle on the apex angle edge of crashproof mound and on the both sides face. After the debris flow is burst, the mud level is gradually increased to a water curtain starting mud level, a mud level sensor transmits mud level 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 curtain is formed, reverse load is applied to the coming debris flow, the debris flow is forced to flow to the two sides to deflect, and the bridge abutments are not impacted and damaged by the debris flow through the bridge.
