Expressway tunnel portal water column grating interception system
The invention discloses an expressway tunnel portal water column grating interception system which is arranged at an expressway tunnel portal and comprises a bayonet area and a warning area, the bayonet area is located in front of the expressway tunnel portal, and the warning area is located in front of the bayonet area. The tail end of the warning area and the front end of the bayonet area are each provided with a water column intercepting device and a grating intercepting device, and a blocking barrier gate is arranged at the position, close to an expressway tunnel portal, behind the bayonet area. The water column intercepting device and the grating intercepting device are arranged at the tunnel portal, water columns and laser cause visual perception to generate flexible intercepting of a blocking effect, a non-violent collision intercepting method is adopted, vehicles running at a high speed are effectively prevented from decelerating and buffering, the vehicles are effectively stopped in a short time, and the safety of the vehicles is improved. The defect that medium and long tunnel unattended stations cannot stop vehicles from entering dangerous road sections in the first time is overcome, and personal safety risks caused by direct manual on-site vehicle stopping are also avoided.
本发明公开了一种高速公路隧道口水柱光栅拦截系统，拦截系统设于高速公路隧道入口处，包括卡口区域和警示区域，卡口区域位于高速公路隧道口的前方，警示区域位于卡口区域的前方，警示区域的尾端和卡口区域的前端均设有水柱拦截装置和光栅拦截装置，卡口区域的后方靠近高速公路隧道口处设有阻拦道闸。本发明在隧道口设置水柱拦截装置和光栅拦截装置，通过水柱和激光引起视觉感观产生阻挡作用的柔性拦截，采用非剧烈硬性碰撞的拦截方法，有效阻止高速行驶的车辆实现减速、缓冲，在较短时间内有效拦停车辆，解决了中、长隧道无人值守站无法第一时间阻拦车辆进入危险路段的不足，也避免了人工直接现场拦截车辆带来的人身安全风险。
