Technical Field

[0001] The utility model relates to the technical field of mileage piles, in particular to a multifunctional integrated ten-meter-level mileage pile signboard device for tunnels. Background Art

[0002] By the end of 2023, there were 27,297 highway tunnels nationwide, with a total length exceeding 30 million meters. According to relevant regulations, "regular inspections of tunnel civil structures should be conducted annually, based on the tunnel's technical condition, preferably annually, for a maximum of three years." Based on the results of regular, frequent, and emergency inspections, tunnels that have defects or defects require further investigation. Consequently, tens of thousands of kilometers of tunnels require inspection annually. However, a critical step in tunnel inspection—mileage pile number calibration—has remained stuck in the traditional model. Prior to tunnel inspection, mileage pile numbers are marked on the tunnel side walls using paint or other materials. Inspection and maintenance are then performed based on these painted pile numbers. However, this method lacks legibility and is difficult to preserve long-term. Furthermore, the pile numbering rules for each inspection are inconsistent, resulting in poor comparability of inspection results over time and a lack of clarity regarding the development of defects, which greatly inconveniences and challenges maintenance and management.

[0003] At the same time, according to the second volume of the "Highway Tunnel Design Specification JTG D70 / 2-2014" on traffic engineering and ancillary facilities, in order to improve poor visibility and enhance driving safety, tunnels need to be equipped with two-way delineators with a spacing of 6-15m.

The connecting assembly 2 is arranged on the sign assembly 1 for being pressed and connected with the sign assembly 1. The sign assembly 1 includes a bracket 101, two reflectors 102, a mounting plate 103 and a sign 104. The two reflectors 102 are fixedly mounted on the outer wall of the bracket 101. The mounting plate 103 is fixedly mounted on the bracket 101 by fasteners. The sign 104 is fixedly mounted. On the top of the mounting plate 103, a reflective film is provided on the surface of the sign 104. More specifically, the light reflected by the pair of reflectors 102 is used to guide the sight of the moving car. At the same time, when the staff are inspecting along the way, the reflected light from the two reflectors 102 is used to prompt the position of the sign 104 and the bracket 101, so that the staff can find the position of the sign 104 and the bracket 101 for inspection. It has the advantages of guiding the driving personnel to the position of the sign 104, marking the position of the sign 104, and reminding the staff of the position of the sign 104 for inspection and maintenance.

[0027] In addition, the cross section of the bracket 101 is trapezoidal.

[0028] In addition, the two reflectors 102 are made of the same material.

[0029] In addition, the mounting plate 103 is made of stainless steel.

[0032] Second embodiment

[0033] Based on the multifunctional integrated ten-meter mileage post sign device for tunnels provided in the first embodiment of the present application, the second embodiment of the present application proposes another multifunctional integrated ten-meter mileage post sign device for tunnels. The second embodiment is merely a further solution of the first embodiment as a further solution of the present invention, and the implementation of the second embodiment will not affect the independent implementation of the first embodiment.

[0034] like Figure 7-Figure 8As shown, in the second embodiment of the present utility model, a multifunctional integrated ten-meter mileage pile sign device for a tunnel includes an L-shaped plate 3 and a reflector 2 4. The L-shaped plate 3 is fixedly mounted on the outer wall of one side of the mounting plate 103 by bolts, and the reflector 2 4 is fixedly mounted on the outer wall of one side of the L-shaped plate 3. More specifically, the L-shaped plate 3 is picked up, placed vertically and close to the tunnel wall, and the L-shaped plate 3 is fixed together with the mounting plate 103 to the tunnel wall by bolts. The reflector 2 4 faces opposite to the driving direction of the lane in the tunnel, and the light reflected by the reflector 2 4 is used to guide the sight of the moving car. The mounting plate 103 and the sign 104 are fixed on the L-shaped plate 3 to mark the tunnel pile number and guide driving in the tunnel.

[0035] Working principle:

[0036] Step 1: Installation and fixation, pick up the mounting plate 103, place the mounting plate 103 between the middle plate 205 and the bracket 101 and fit it on the bracket 101, at this time pull the middle plate 205, the middle plate 205 drives the movable plate 203 to move and adjust the position, the middle plate 205 drives the movable plate 203 and the T-shaped plate 202 to move, the T-shaped plate 202 slides on the circular plate 201, and after the connection between the middle plate 205 and the mounting plate 103 is aligned, press the middle plate 205, the middle plate 205 slides in the sliding mouth 204 and approaches the mounting plate 103, the middle plate 205 drives the magnetic ring close to the mounting plate 103 and adsorbs the restricted position, at this time, the external fastener passes through the mounting plate 103 and the middle plate 205 knob on the bracket 101, fixes the mounting plate 103 and the middle plate 205, and then fixes the bracket 101 on the tunnel wall.

[0037] Step 2: Prompt and guide. When the driver is driving, the light laid in the tunnel is refracted downward by reflector 102. When the staff is inspecting along the way, the light reflected by the two reflectors 102 is used to guide the sight of the moving car. At the same time, the reflected light can also prompt the position of the sign 104 and the bracket 101, so that the driver's sight is guided and he notices the position of the sign 104 and the bracket 101.

[0038] The reflector 102 of the device serves to guide the line of sight of vehicles in the tunnel, and the mileage post sign 104 serves to locate the vehicle, so that the same "ruler" can be used for inspection and maintenance work over the years. While meeting the requirements of the contour mark function (the light reflection function of the reflector 102), it also has the tunnel mileage positioning function, accurately determining the location of the defect, thereby providing more scientific data support for tunnel maintenance.

[0039] The above is only a preferred specific implementation method of the present invention, but the protection scope of the present invention is not limited to this. Any technician familiar with the technical field within the technical scope disclosed by the present invention can make equivalent replacements or changes based on the technical solution and utility model concept of the present invention, which should be covered by the protection scope of the present invention.
