Abstract

Disclosed is an expressway tunnel warming post device, comprising warning posts made of round galvanized tubes; the cylinder of each warning post is divided into an upper part, a middle part and a lower part; wherein red reflective membranes are inlaid on the upper part and the lower part; a white reflective membrane is inlaid on the middle part, the lower end of which is connected with a pedestal; the pedestal is fixed on a curb cover duck board through expansion bolts; a plurality of warning posts are arranged on the curbs at two sides of the road in the tunnel according to the line type of the road; and the warning posts are arranged at equal intervals and the optimal interval is 20 meters. The expressway tunnel warming post device is simple to install and easy to maintain, and can reflect the light brightly and give striking guidance, and requires no power source, thus improving the brightness contrast between the inside and the outside of the tunnel and improving the safety of the road tunnel.

Description

Freeway tunnel warning post device

Technical field

The utility model belongs to the technical field of illumination of highway tunnel security warning system, especially belongs to freeway tunnel warning post device.

Background technology

For a long time, illumination of highway tunnel and the contradiction that ensures safety and drive a vehicle and exist, perplexing freeway management personnel and human pilot always, after driving enters the tunnel, pilot's line of vision is suddenly by strong deepening, inside and outside " white hole; black hole " the obviously luminance contrast that forms in tunnel, cause driver's visual discomfort to be answered, thereby, may influence traffic safety or, cause power failure because of tunnel intraoral illumination burst accident, dark driving is by inducing faint reflective guiding of reflector in the hole in car light and the tunnel, make the driver feel that effective track guiding definition is not enough, produce depression and sense of insecurity, these factors are all very easily brought out the generation of tunnel safety accident.

At present, highway lighting adopts high pressure sodium lamp mostly, the color rendering property of its illumination than other light fixtures a little less than, again because the special construction in tunnel, flue dust in the tunnel is difficult for dissipating, and it is untimely to ventilate, and flue dust reflects and causes the brightness of light to reduce, the driver influences safety operation effectively producing the dimness of vision in the sighting distance.Therefore, strengthening brightness of illumination and look dominance energy, is to ensure tunnel safety, and comfortable driving alleviates the effective ways of nervous sense and sense of depression, and the contradiction that exists between these methods and solution lighting energy saving is again the important topic that the highway administration personnel face.In long-term groping put into practice, use for reference at the strategically located and difficult of access position of speedway the reflecting sign of warning is set, make it the strong reflective of driving at night and induce effect, playing important function aspect drive a vehicle vision, the security warning.Through repeatedly field investigation, demonstration and experiment repeatedly are with this scheme with the introducing tunnel is set.

Summary of the invention

The purpose of this utility model is to provide a kind of freeway tunnel warning post device, warning post is by high 600mm, diameter 76mm, the coating steel pipe of wall thickness 4.6mm is made, cylinder two is partly inlayed the red reflective membrane of subsides up and down, white reflection film edge is attached to the centre of cylinder, form two red one white high intensity level ULS reflective membranes, the lower end of circular warning post and the steel plate of base 150 * 150 * 10mm are welded to connect, with expansion bolt base is fixed on road crest face, reflective warning post is vertical with the road surface on both sides, the road surface curb lid ditch plate in the tunnel installs setting, reflective warning post is installed by the highway line style, begin to outlet from tunnel entrance, spaced set, every optimal spacing is 20 meters.

Adopt the beneficial effect of the technical program, simple reflective becoming clear is installed, induce eye-catching, both artistic and practical, be easy to safeguard, do not need power supply, make the contrast of the inside and outside brightness in tunnel obtain effective improvement, improve the security performance of tunnel road, reduced the road accident rate in tunnel.

Description of drawings

Fig. 1 is the structure chart of the utility model freeway tunnel warning post device;

Fig. 2 is provided with schematic diagram for the freeway tunnel warning post in the tunnel;

Among the figure: 1-the warn red reflective membrane of cylinder, 2-white reflection film, 3-, 4-base, 5-expansion bolt, 6-curb lid ditch plate.

The specific embodiment

Freeway tunnel warning post device described in the utility model, the contrast accompanying drawing is further described, the warning post device comprises that the cylinder 1 of warning made by circular galvanized pipe, divide upper, middle and lower three on the cylinder partly, wherein upper and lower two partly inlay the red reflective membrane 3 of subsides, middle partly edge pastes white reflection film 2, forms high intensity level ULS reflective membrane red and white.The warn lower end of cylinder 1 is connected with base 4, by four expansion bolts 5 its base 4 is fixed on the curb lid ditch plate 6.The cylinder 1 of warning is arranged in the whole tunnel, on the both sides curb lid ditch plate 6 on total length road surface, is provided with many by the highway line style perpendicular to the road Plane Installation, and to exporting spaced set, every optimal spacing is 20 meters from tunnel entrance.
