The invention provides a protection device for a highway tunnel and a highway tunnel structure. The protection device comprises a fixing part, a baffle structure and a driving mechanism. The fixing part is embedded in the tunnel, and a movable groove is formed in the fixing part; the baffle structure is movably contained in the movable groove. The driving mechanism is connected to the baffle structure and used for driving the baffle structure to stretch into or retract into the movable groove. According to the protection device, the driving mechanism is arranged to be matched with the baffle structure, the position of the baffle structure can be adjusted according to the actual protection requirement, and therefore the effect of reducing the traffic accident risk of the vehicle is achieved. According to the highway tunnel structure, by arranging the protection device, when a vehicle passes through the junction of the tunnel and the bridge, the protection device can protect the vehicle, so that the vehicle is prevented from breaking through the bridge guardrail and falling off, and the use safety is improved.
Description
technical field [0001] The invention relates to the technical field of road tunnels, in particular to a protective device for road tunnels and a road tunnel structure. Background technique [0002] Tunnels refer to engineering buildings formed in the ground, which is a form of human use of underground space. Tunnels can be divided into traffic tunnels, hydraulic tunnels, municipal tunnels, mine tunnels, military tunnels, etc., anchorages and highways of suspension bridge tunnels The horizontal, vertical and transverse intersections between tunnels will overlap, connect and interfere with each other. Tunnel excavation has a great impact on the strength of the tunnel anchor rock mass and the reliability of the tunnel anchor. Highway tunnels belong to traffic tunnels, while highway tunnels are A channel dedicated to vehicle transport. Along with the development of social economy and production, a large number of highways have appeared, which put forward higher standards for hi...
