Water diversion and water delivery tunnels are usually designed as small-section tunnels. In the process of tunnel excavation, it usually involves the coordinated work of multiple construction equipment (such as boring machines, loaders, scrapers, slag trucks, shotcrete machines, work platforms, etc.). Due to the small cross-sectional size and long length of the small-section long tunnel (its cross-sectional width is 3~5.5m and the cross-sectional area is 10~30m 2 , length not less than 100m), cannot meet the needs of two-way traffic, various construction equipment can only pass one-way in the tunnel, resulting in traffic jams and inability to pass during the passage, which reduces the construction efficiency, seriously affects the advancement of tunnel construction, and prolongs the construction period; when traffic jams occur, not only manual command is required for evacuation, but also the vehicle avoidance path is too long, which makes this method not only time-consuming and labor-intensive, but also increases the cost of machinery use.

It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0024] refer to Figure 1 , Figure 2The traffic indication device in a small-section long tunnel of an exemplary embodiment of the utility model includes a vehicle sensing device 4 and a traffic light 3, and the traffic light 4 is arranged corresponding to the vehicle sensing device 3; the main tunnel 1 of the small-section long tunnel extends from the entrance to the tunnel construction surface or the exit, and one or more shelters 2 are arranged in the length direction of the main tunnel 1, and the shelters 2 are arranged at the side position of the main tunnel 1, and the shelters 2 are connected to the main tunnel 1, and one or more vehicle sensing devices 4 are arranged in the main tunnel 1 along the length direction of the main tunnel 1, and the traffic light 3 is arranged in the middle of the main tunnel 1.

[0025] Traffic light 3 is a two-way indicator light, and its front and back are used to display the same or different colors respectively, and the two colors are used to indicate the passage of vehicles or to stop and avoid. For example, when the front of traffic light 3 (the front direction from the main tunnel entrance to the exit, and the reverse direction is the back) is green, the back of the traffic light is red, and vehicles from the main tunnel entrance to the exit continue to drive, and vehicles from the main tunnel exit to the entrance stop and avoid. When vehicles from the entrance to the exit and vehicles from the exit to the entrance meet, traffic jams can be reduced to ensure the smooth driving of vehicles in the tunnel.

[0026] The traffic light 3 is fixed to the top of the main hole 1 by a bracket. The bracket can be a hollow rectangular bracket. The top of the bracket is fixed to the top of the main hole 1 by bolts. The front and rear sides of the bracket are both open. The traffic light 3 is fixed to the middle of the bracket. The light of the traffic light 3 can be irradiated into the main hole through the openings at the front and rear ends of the rectangular bracket to indicate the passage of vehicles. The bracket can not only support the traffic light 3 and fix the traffic light 3 on the top of the main hole 1, but also protect the traffic light 3. When the construction equipment is moving in the main hole, the rectangular bracket can prevent the items loaded in the construction equipment from scratching and damaging the traffic light.

[0027] The vehicle sensing device 4 is respectively arranged at the entrance of the main tunnel 1, both sides of the entrance of the escape tunnel 2, the exit of the main tunnel 1 or near the tunnel construction surface. The vehicle sensing device 4 can adopt a microwave detector, an ultrasonic detector or an infrared detector. In the tunnel, the microwave detector, the ultrasonic detector or the infrared detector is easy to install and maintain, and can effectively detect the vehicle information; the vehicle sensing device 4 is arranged on the side of the main tunnel 1, and its setting height is 1~3m. The vehicle sensing device 4 is fixed on the side of the main tunnel 1 through a bracket; the left and right ends of the vehicle sensing device 4 are provided with signal sensing points, and sensors (infrared sensors, ultrasonic sensors, microwave sensors, etc.) are arranged at the sensing points. The signal sensing points on the left and right ends of the vehicle sensing device 4 can sense the vehicle (construction equipment) information. According to the order of the vehicle information sensed by the signal sensing points on the left and right ends of the vehicle sensing device 4, the direction of vehicle travel can be determined, thereby changing the color of the traffic light 3.

[0028] refer to Figure 3 The traffic indication device in a long tunnel with a small cross-section also includes a power module and a signal processing module. The power module is electrically connected to the signal processing module and the vehicle sensing device respectively. The vehicle sensing device is communicatively connected or electrically connected to the signal processing module. The signal processing module is communicatively connected or electrically connected to the traffic light.

[0029] When a vehicle passes through the main tunnel, the two sensing points of the vehicle sensing device detect the vehicle signal. The detection point close to the vehicle detects the signal first, and the detection point far away from the vehicle detects the signal later. The two sensing points send different signals to the signal processing module according to the order of the detected signals. After the signal processing module receives the signal, it processes the received signal to determine the direction of the vehicle. After determining the direction of the vehicle, the signal processing module sends a control signal to the traffic light, so that the front and back of the traffic light display the same or different colors respectively, to indicate the vehicle to pass or avoid; the traffic light can use an independent power supply (such as a battery or an AC power supply), or it can be electrically connected to a power supply module, and the power supply module uses a battery or an AC power supply.

[0030] At the location of the car shelter 2, the traffic light 3 is arranged between two vehicle sensing devices 4. After a vehicle drives to the location of the car shelter, it can enter the car shelter in time to avoid passing vehicles, thereby improving the traffic efficiency of vehicles.

[0031] The traffic indication device in a small-section long tunnel of the utility model is mainly suitable for a small-section tunnel with a length of not less than 100m. When the length of the small-section tunnel is less than 100m, the vehicle avoidance path is short due to the small overall length of the tunnel, and the traffic indication device may not be provided; when the length of the small-section tunnel is between 100 and 400m, a car shelter 2 may be provided in the middle of the main tunnel 1; when the length of the small-section tunnel is greater than 400m, more car shelters 2 may be provided in the length direction of the main tunnel 1, and the distance between adjacent car shelters 2 is 200 to 300m. The provision of more car shelters 2 may shorten the vehicle avoidance path and improve the vehicle traffic efficiency. The car shelter 2 may be provided on one side of the main tunnel 1 or on both sides of the main tunnel 1.

After the vehicles in the main tunnel 1 drive out of the main tunnel, the traffic indicator light 3 displays a green light on the front, indicating that the vehicles outside the main tunnel 1 can enter the main tunnel 1.

[0033] At the exit of the main tunnel 1, when there is no vehicle driving out of the main tunnel 1 from the exit, the back of the traffic indicator 3 shows a green light, and vehicles can drive into the main tunnel 1 from the exit of the main tunnel 1; when there is a vehicle driving out of the main tunnel 1 from the exit and a vehicle outside the main tunnel 1 enters the main tunnel 1, the signal sensing points at the left and right ends of the vehicle sensing device 4 in the main tunnel 1 detect the vehicle signal, and the signal sensing point on the left side of the vehicle sensing device 4 ( The signal is detected first by the signal sensing point on the right ( After the signal is detected, according to the detected signal sequence, the front of the traffic indicator 3 displays a green light and the back displays a red light, indicating that the vehicles outside the main tunnel 1 should give way. After the vehicles in the main tunnel 1 drive out of the main tunnel, the back of the traffic indicator 3 displays a green light, indicating that the vehicles outside the main tunnel 1 can enter the main tunnel 1.

[0034] At the position of the escape hole 2 (from the entrance to the exit), the front and back of the traffic light 3 are initially in green state, and the vehicle sensing devices 4 on the left and right sides of the traffic light 3 are at an equal distance from the traffic light 3; when two vehicles are traveling towards each other, the vehicle sensing devices 4 on both sides of the traffic light 3 detect vehicle signals. When the vehicle sensing device 4 on the left side of the traffic light 3 detects vehicle signals first, it indicates that the vehicle on the left side of the traffic light 3 is closer to the traffic light 3 and the escape hole 2, the front of the traffic light 3 displays a red light, and the back displays a green light, and the vehicle on the left side of the traffic light 3 enters the escape hole first. 2. After the vehicle on the right side of the traffic light 3 passes through the escape tunnel 2, the front of the traffic light 3 displays a green light, and the vehicle on the left side of the traffic light 3 enters the main tunnel 1 from the escape tunnel 2 and continues to drive; when the vehicle sensing device 4 on the left side of the traffic light 3 detects a vehicle signal and the vehicle sensing device 4 on the right side does not detect a vehicle signal, the front of the traffic light 3 displays a green light to indicate that the vehicle passes. When the vehicle drives to the position of the vehicle sensing device 4 on the right side of the traffic light 3, the vehicle sensing point on the left side of the vehicle sensing device 4 detects the vehicle signal first, and the color of the front and back of the traffic light 3 remains unchanged. The display mode of the traffic light 3 from the exit to the entrance of the escape tunnel 2 is the same as that of the traffic light 3 from the entrance to the exit.

[0035] The above is only a detailed description of the specific implementation of the utility model, rather than a limitation of the utility model. Various substitutions, modifications and improvements made by technicians in the relevant technical field without departing from the principle and scope of the utility model should be included in the protection scope of the utility model.
