Description

Isolation protective guard capable of automatically warning under pressure

Technical Field

The utility model relates to a road traffic facility technical field especially relates to an isolation rail guard of automatic warning of pressurized.

Background

The existing urban road isolation guardrail separates motor vehicles, non-motor vehicles and pedestrian traffic, and longitudinally separates roads on a cross section, so that the motor vehicles, the non-motor vehicles and the pedestrians can drive in different lanes, the safety of the road traffic is improved, and the traffic order is improved. On a city road, a driver is warned to pay attention to the existence of the isolation fence, pedestrians, non-motor vehicles and the like by installing the isolation fence with a concise and clear outline, so that the traffic accidents are prevented. The urban traffic guardrail is not only simple isolation of roads, but also aims to clearly show traffic flow and transmit urban traffic information, establish a traffic rule and maintain traffic order, so that the urban traffic achieves the effects of safety, rapidness, order, smoothness and convenience. The isolation fence can also be used as a safety fence for blocking pedestrians from crossing the road, which is important for road safety. After the existing urban road isolation fence is transported to a project site, steel lining parts of all stand columns are firstly inserted into a stable base and fixed on the ground by using internal expansion bolts, layout is carried out according to the route of a road, and after all basic layout is finished, each section of isolation fence is connected by using special bolts so as to separate the road and stabilize the traffic order.

Although the existing urban road isolation fence can play a role in separating roads, the pedestrian illegal crossing over the isolation fence is rare, and the pedestrian illegal crossing over the isolation fence often has a lucky psychology, can cause safety accidents in order to copy roads to enter a motor lane, and is also not responsible for the lives of the pedestrians; the existing urban road isolation fence can not effectively prevent pedestrians from crossing, and meanwhile, pedestrians in front of a motor vehicle driver can not be warned to cross the fence in an illegal way, so that traffic accidents can be caused in sight blind areas, and life safety is threatened. When a motor vehicle driver drives on an urban road, the attention of the motor vehicle driver is dispersed due to various traffic signs on the road, the motor vehicle driver generally cannot pay attention to the situation of one place of an isolated fence, and when a pedestrian illegal traffic rule crosses the isolated fence, the driver has no way to reflect the situation in time.
