Abstract

The present invention provides a lifting type entry blocking device having a turning function for blocking entry to tunnels, bridges, and underpasses, which can protrude above the road surface to control vehicle entry or be inserted below the road surface to allow vehicle entry or turning. The lifting type entry blocking device comprises: a buried housing unit that is buried underground so that its upper end is exposed through the road surface and is equipped with an upper opening; a guardrail that moves to a lowered position accommodated inside the buried housing unit and a raised position in which a column and a rail protrude above the road surface through the upper opening; and a lifting mechanism that moves the guardrail up and down. Thus, when installed as an entry blocking device at the entrance of a tunnel, bridge, or underpass, it descends below the road surface during normal times so as not to obstruct the driver's forward view, thereby significantly reducing the risk of accidents caused by the entry blocking device, and in the event of an accident or disaster, it protrudes above the road surface to stably control vehicle entry.

Description

Elevating access-blocking apparatus having turning-back function for preventing entry into tunnel, bridges, and underpass The present invention relates to a lifting type entry blocking device having a turning function for blocking entry to tunnels, bridges, and underpasses, comprising a guardrail that descends below the road surface or rises above the road surface to protrude, so as to enable emergency turning of vehicles and emergency vehicle control in the event of a fire or accident in tunnels, bridges, and underpasses. While tunnels, bridges, and underpasses enhance the convenience and efficiency of vehicle traffic, they can pose a serious risk to numerous vehicles and drivers once situations such as fires, traffic accidents, or falling objects occur. In other words, due to the enclosed spatial structure of tunnels or underpasses, smoke and toxic gases spread rapidly upon the occurrence of a fire, making evacuation and firefighting difficult. Furthermore, if subsequent vehicles continue to enter the accident site, secondary and tertiary collisions may occur, potentially exacerbating casualties and property damage. Similarly, major accidents on bridges can also be challenging for rescue operations due to the isolated environment, making it crucial to promptly block vehicle entry to the accident site to prevent the accident from escalating. As such, considering the characteristics of tunnels, bridges, and underpasses, there is a growing need for entry blocking devices to prevent subsequent vehicles from entering prior to the accident site in the event of a disaster. Meanwhile, conventionally, Variable Message Signs (VMS) are installed at the entrances of tunnels, bridges, and underpasses to provide accident or disaster information to subsequent drivers, thereby blocking the entry of subsequent vehicles. For example, Registered Patent Publication No. 10-2836837 (hereinafter referred to as “Prior Art Document 1”) discloses a lifting type entry blocking device installed in front of a tunnel or underpass, etc., which controls vehicle entry by lowering a barrier to display a warning message or image to the driver indicating a ban on entry when a disaster occurs (see FIG. 1). In addition, Korean Patent Publication No. 10-2025-0060077 (hereinafter referred to as “Prior Art Document 2”) discloses a movable tunnel and underpass entry blocking device in which a truss structure equipped with a truss beam is installed at the entrance of a tunnel or underpass, a barrier housing equipped with a barrier is connected to the truss beam and installed to move left and right, and in the event of a disaster, the barrier descends from the barrier housing to control vehicle entry (see FIG. 2). In addition, Registered Patent Publication No. 10-2087553 (hereinafter referred to as “Prior Art Document 3”) discloses an automatic control tunnel entry blocking device installed at the entrance of a tunnel, which lowers a barrier to control vehicle entry when a disaster occurs inside the tunnel (see FIG. 3). As described in the aforementioned prior art documents 1 to 3, when an entry barrier that controls vehicle entry at the entrance of a tunnel, bridge, or underpass is provided to protrude above ground, it obstructs the driver's forward view, which may dampen driving psychology or cause sudden braking and sudden lane changes, and there is a problem that further increases the risk of accidents, especially during bad weather or night driving. In addition, access barriers protruding above ground limit road width and height, posing a problem that restricts road infrastructure improvements such as road expansion, securing pedestrian space, placement of guardrails, and maintenance of drainage facilities. Meanwhile, median barriers are being installed in the center of roads, including tunnels, bridges, and underpasses, to separate uphill and downhill lanes and prevent vehicles from crossing the center line and colliding with vehicles traveling in the opposite lane. The aforementioned median divider is designed to physically separate the uphill and downhill lanes by connecting multiple pillars installed at regular intervals along the length of the road via rails, thereby preventing vehicles from crossing the center line and entering the opposite lane; however, it has a limitation in that it cannot allow vehicles to cross the center line and turn around in the direction of entry in the event of an emergency in tunnels, bridges, or underpasses.

Figure 2 is a structural diagram of a movable tunnel and underpass entry blocking device according to prior art document 2. Figure 3 is a structural diagram of an automatic control type tunnel entry blocking device according to prior art document 3.
