Abstract
Description
Technical Field
[0001] The invention relates to the technical field of road driving safety, and in particular to an additional road surface and a construction method for improving driving safety in areas prone to waterlogging. Background Art
[0002] Highway pavement drainage mainly relies on the composite slope (the vector sum of the transverse slope and the longitudinal slope) to achieve gravity flow of water and discharge it out of the highway pavement limit. At various stages of the highway project life cycle, there are some unfavorable factors that lead to thick water film, stagnant water areas, etc. on the road surface, affecting driving safety.
[0003] For example, during the highway design stage, when the main project has superelevation, the road section with a small composite slope will lead to slow drainage and form a thick water film area; in the confluence section between the main line and the main line, and the main line and the ramp, the roadbed becomes wider and the drainage path becomes longer, and thick water film areas will also form in some areas; during the construction process, there will be a lack of quality control measures, and some sections will have small slopes and depressions, thus forming thick water films and stagnant water areas; during the operation process, vehicle loads and uneven subsidence of the foundation will cause some sections to have small slopes and depressions, resulting in the formation of thick water films and stagnant water areas. Thick water films and stagnant water areas on the road surface reduce the adhesion of vehicle tires, becoming a safety hazard for high-speed vehicles, and causing frequent traffic accidents, especially in rainy days.
[0004] Currently, the only effective measure to deal with traffic accidents on rainy days is to slow down, but sections of roads with waterlogging are still areas where traffic hazards are concentrated. Traffic control can only provide warnings by setting up road signs such as "Roads are slippery on rainy days, please be careful", but it cannot indicate the specific dangerous areas on sections of roads prone to waterlogging, and cannot effectively reduce the incidence of traffic accidents. Summary of the invention
[0005] In view of the problems existing in the prior art, the present invention provides an additional road surface and construction method for improving driving safety in areas prone to waterlogging, solving the problems of small visibility distance of flooded sections on rainy days, slippery driving tires, and difficulty in dissipating water in waterlogged areas, thereby further reducing the hidden dangers of traffic accidents on rainy days and lowering the incidence of traffic accidents.
[0006] The technical solution of the present invention is as follows: In the first aspect of the present invention, an additional road surface is provided to improve driving safety in areas prone to waterlogging.

In some embodiments of the present invention, the solid hydroplaning line and the discontinuous hydroplaning line have set colors; the thickness of the solid hydroplaning line and the discontinuous hydroplaning line is greater than the maximum water depth minus the water-breaking depth of the tire at the vehicle running speed. In a second aspect of the present invention, a method for constructing a road surface for improving driving safety in areas prone to waterlogging is provided, comprising: When the additional road surface only performs a warning function: Investigate and determine the road sections prone to waterlogging, determine the scope of waterlogging impact, delineate the scope of road reconstruction based on the scope of waterlogging impact, and conduct additional road surface design for the road reconstruction scope, design the set color, and design the set reflectivity; use spraying and painting technology to construct additional road surfaces in areas prone to waterlogging; When the additional road surface performs warning and anti-skid functions: Determine and calculate the depth and range of water accumulation in areas prone to water accumulation under rainfall intensity; calculate the thickness of the additional anti-skid pavement at the running speed on rainy days; use spraying and painting technology to construct additional pavement with a set color, set reflectivity, and set thickness in areas prone to water accumulation; When the additional road surface performs warning, anti-skid and drainage functions: The thickness of the solid hydroplaning line and the discontinuous hydroplaning line is calculated according to the depth of the accumulated water, the line width and interval width of the solid hydroplaning line and the discontinuous hydroplaning line along the vehicle travel direction are calculated according to the influence range of the accumulated water, the gap width between several line segments of the discontinuous hydroplaning line and the line segment inclination are calculated, and the use method and combination ratio of the solid hydroplaning line and the discontinuous hydroplaning line are obtained; Mill and reconstruct the longitudinal markings on both sides of the road in the area affected by waterlogging, and construct them as drainage markings; Solid hydroskiing lines, intermittent hydroskiing lines and drainage markings are constructed in water-prone areas of the road section. There are certain intervals between the solid hydroskiing lines and intermittent hydroskiing lines, and the intervals are connected to the drainage gaps of the drainage markings on both sides.
[0010] In some embodiments of the present invention, the physical hydroplaning tire line is arranged perpendicular to the driving direction, and the marking width of the physical hydroplaning tire line along the vehicle driving direction is calculated according to the design speed of the road section and the depth of water accumulation; There is a spacing distance between the several marking segments of the intermittent hydroplaning tire line, and the spacing distance is calculated comprehensively according to the depth of water accumulation in the road section, the design speed of the road section and the drainage distance, and the maximum width of the spacing distance is less than the minimum tire width of the vehicle passing through the road section; The physical width, spacing and inclination of several marking segments perpendicular to the direction of vehicle travel are calculated based on the composite slope of the road section, the vehicle running speed and the depth of water accumulation; The width of the intermittent hydroplaning tire line along the vehicle's driving direction is calculated based on the design speed of the road section and the depth of water accumulation. In some embodiments of the present invention, the distance between the solid hydroplaning line and the intermittent hydroplaning line along the vehicle travel direction, as well as the number and ratio of the solid hydroplaning line and the intermittent hydroplaning line are calculated based on the design speed of the road section and the depth of water accumulation; The thickness of the solid hydroplaning line and the intermittent hydroplaning line is calculated based on the longitudinal slope, transverse slope, water accumulation depth and design speed of the road section. Specifically, the thickness of the solid hydroplaning line and the intermittent hydroplaning line is greater than the maximum water accumulation depth minus the tire water breaking depth at the design speed of the road section. In some embodiments of the present invention, when the setting area of the solid hydroplaning line and the intermittent hydroplaning line contains a lane dividing line and a lane edge line, the lane dividing line and the lane edge line are constructed as drainage markings, and the drainage gap of the drainage markings is set at an acute angle to the driving direction in the extension direction away from the road surface. One or more technical solutions of the present invention have the following beneficial effects: In sections prone to waterlogging and traffic accidents, the existing reminder method is to set up an electronic screen on the waterlogged section to display a warning sign that says "The road is slippery in rainy days, pay attention to safety", but it is not possible to set up warning signs in all sections prone to waterlogging, which is insufficient to remind passing vehicles, and it is not possible to accurately remind the waterlogging situation of the section. The present invention provides a road surface and construction method for improving driving safety in areas prone to waterlogging, which can set up additional road surfaces in advance in the sections prone to waterlogging, and has the functions of warning, anti-skid, and drainage, which can accurately warn passing vehicles to pay attention to driving safety and avoid traffic accidents caused by vehicle slipping; By setting the additional road surface with a continuous and regular shape proposed by the present invention on a road surface prone to water accumulation, drivers and passengers can determine the existence and scope of the water accumulation area according to whether there is the additional road surface on the road, thereby increasing the visual recognition distance and reminding the drivers and passengers to slow down in advance to ensure driving safety; further, the additional road surface has a set thickness and a friction coefficient that is not less than the set driving road surface, which can provide support and friction for the vehicle, increase the critical speed of water sliding on the road surface in the water accumulation area, and further help the vehicle to slow down in the water accumulation area on the basis of the deceleration warning for the driver and passengers to avoid water sliding and instability; further, by setting the shape and structure of the additional road surface so that it has a certain drainage function, it can be achieved that when the vehicle passes through the additional road surface in the water accumulation area, the water is removed from the road surface to ensure driving safety.
[0011] Warning function: the additional road surface proposed by the present invention is regularly arranged, and the solid part has a specific color and thickness. It has the same reflected light properties under natural light and reflected light. When the additional road surface is covered by water, it will show different reflected light properties. Through the different reflected light properties in the horizontal and vertical directions, the driver can judge the rain-covered area and its boundaries, and warn the driver to pay attention to safety; Anti-skid function: the additional road surface proposed in the present invention has a set thickness, and its contact surface is located within the water-breaking depth of the tire on rainy days. The set thickness is calculated based on factors such as the depth of easy water accumulation and the vehicle's running speed, to ensure that when the moving vehicle hydroplans at the running speed, its tires can contact the tire guide line, and maintain a controllable driving trajectory through the friction force given by the tire guide line, eliminating the danger caused by vehicle posture instability.
[0012] Drainage function: in the additional road surface proposed by the present invention, the intermittent hydroplaning tire line is composed of a number of marking line segments arranged in a parallelogram and arranged at regular intervals, and the acute angles on both sides of the number of marking line segments are respectively facing the drainage marking lines on both sides of the road, and the interval distance of the number of marking line segments is at a certain angle to the driving direction. The width of the interval distance and the angle of the acute angle of the parallelogram are calculated according to the vehicle running speed, the depth of easy water accumulation, etc. When the tire of the vehicle presses over the intermittent hydroplaning tire line, the water in the interval distance will be squeezed to form a water flow at a certain angle to the driving direction, and the water flow pushes the static water to flow along the interval gap between the real hydroplaning tire line and the intermittent hydroplaning tire line to both sides of the road and be discharged into the driving lane; in addition, because the two sides of the number of marking line segments of the intermittent hydroplaning tire line form acute angles, a water accumulation breaking front will be formed. When the tire of the vehicle passes over this place, the accumulated water will form water mist through the acute angle and dissipate in the air, which also plays a drainage function; Drainage markings are used in conjunction with solid hydroskiing lines and intermittent hydroskiing lines on longitudinal markings such as lane dividing lines and lane edge lines. They also have warning, drainage and anti-skid functions. Reinforced drainage markings are used on longitudinal markings, and their drainage gaps are connected with the interval gaps between several solid hydroskiing lines and intermittent hydroskiing lines, so that accumulated water can follow the direction of the water flow, thereby enhancing the drainage function.

[0015] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.
[0016] Example 1 In a typical embodiment of the present invention, Figure 1-4 As shown, an additional road surface is proposed to improve driving safety in areas prone to waterlogging. The additional road surface is arranged on the original road surface 2. The additional road surface is transversely arranged on the driving lane road surface and the hard shoulder road surface in the area prone to waterlogging. The additional road surface has a continuous and regular shape, a set color and reflectivity, and can increase the visibility distance of the waterlogged area.
[0017] Furthermore, the additional road surface is configured as a solid line with a set width and continuously arranged laterally, or a line segment with a set shape and continuously arranged at equal intervals.
[0018] By setting the additional road surface with a continuous and regular shape proposed by the present invention on a road surface prone to water accumulation, the additional road surface has a set color and reflectivity. When covered with water, the refraction of the water layer causes the additional road surface to be lateral discontinuous. Drivers and passengers can determine the existence and scope of the water accumulation area based on whether there is an additional road surface on the road, increase the visual recognition distance, and remind drivers and passengers to slow down in advance to ensure driving safety.
[0019] In this embodiment, since the additional road surface proposed by the present invention is regularly arranged, by setting the physical part to have a specific color and thickness, it has the same reflected light properties under natural light and reflected light. When the additional road surface is covered with accumulated water, it will show different reflected light properties. The different reflected light properties in the horizontal and vertical directions can be used by the driver to judge the rain coverage area and its boundaries, and the driver is warned to pay attention to safety.
[0020] Furthermore, the additional road surface has a set thickness, which is greater than the maximum water accumulation depth minus the water breaking depth of the tire at the vehicle running speed; the additional road surface is made of durable material, and the friction coefficient of the additional road surface is not less than the friction coefficient of the original road surface 2.
[0021] The additional road surface has a set thickness and a friction coefficient that is not less than that of the set driving road surface. It can provide support and friction to the vehicle, increase the critical speed of hydroplaning on the road surface in the flooded area, and further help the vehicle slow down in the flooded area on the basis of the deceleration warning for the driver and passengers, to avoid hydroplaning and instability.
[0022] Since the additional road surface proposed in the present invention has a set thickness, its contact surface is located within the water-breaking depth of the tire on rainy days. The set thickness is calculated based on factors such as the depth of easy water accumulation and the vehicle's running speed. This ensures that when the moving vehicle hydroplans at the running speed, its tires can contact the tire guide line, and maintain a controllable driving trajectory through the friction force provided by the tire guide line, thereby eliminating the danger caused by vehicle posture instability.
[0023] Further, the additional road surface includes a solid hydroskiing tire line 4, an intermittent hydroskiing tire line 3 and a drainage line 1, and the drainage line 1 has a plurality of drainage gaps; a plurality of solid hydroskiing tire lines 4 and a plurality of intermittent hydroskiing tire lines 3 are arranged in intervals in the drainage line 1, and both ends of the plurality of intermittent hydroskiing tire lines 3 and the solid hydroskiing tire line 4 are connected to the drainage line 1 and arranged perpendicularly to the driving direction, and the intermittent hydroskiing tire lines 3 are formed by a plurality of independent additional road surfaces arranged at a certain distance; There is a certain spacing between the plurality of solid water skiing front lines 4 and the discontinuous water skiing front lines 3, and the spacing is connected to the drainage gaps of the drainage marking lines 1 on both sides. Furthermore, the drainage gap of the drainage marking line 1 is arranged at an acute angle to the driving direction in the direction of the composite slope of the road surface; The solid water skiing tire line 4 is arranged in a rectangular shape; The several marking segments of the intermittent hydroplaning line 3 are arranged in a parallelogram shape, and the acute angles on both sides of the several marking segments are respectively oriented towards the composite slope directions on both sides of the road; the maximum width of the spacing distance between the several marking segments of the intermittent hydroplaning line 3 is less than the minimum tire width of the vehicle passing through the road section. Furthermore, the solid hydroplaning line 4 and the intermittent hydroplaning line 3 have set colors; the thickness of the solid hydroplaning line 4 and the intermittent hydroplaning line 3 is greater than the maximum water depth minus the water-breaking depth of the tire at the vehicle running speed. In the additional road surface proposed in this embodiment, the intermittent hydroplaning line 3 is composed of a number of line segments arranged in a parallelogram and arranged at regular intervals. The acute angles on both sides of the line segments face the drainage lines 1 on both sides of the road respectively. The interval between the line segments forms a certain angle with the driving direction. The width of the interval and the angle of the acute angle of the parallelogram are calculated according to the vehicle running speed, the depth of water accumulation, etc. When the tire of the vehicle presses over the intermittent hydroplaning line 3, the water in the interval will be squeezed to form a water flow at a certain angle to the driving direction. The water flow pushes the static water to flow along the interval gap between the solid hydroplaning line 4 and the intermittent hydroplaning line 3 to both sides of the road and discharged into the driving lane. In addition, since the two sides of the line segments of the intermittent hydroplaning line 3 form acute angles, a water accumulation front will be formed. When the tire of the vehicle passes over this place, the accumulated water will form water mist through the acute angle and dissipate in the air, which also plays a drainage function.
[0024] The drainage marking line 1 is used in conjunction with the solid hydroskiing tire line 4 and the intermittent hydroskiing tire line 3, and is used for longitudinal markings such as lane dividing lines and lane edge lines. It also has warning, drainage and anti-skid functions. The reinforced drainage marking line 1 is used on the longitudinal marking line, and its drainage gap is connected with the interval gaps between several solid hydroskiing tire lines 4 and the intermittent hydroskiing tire lines 3, so that the accumulated water can follow the direction of the water flow, thereby enhancing the drainage function.
[0025] In a second aspect of the present invention, a method for constructing a road surface for improving driving safety in areas prone to waterlogging is provided, comprising: When the additional road surface only performs a warning function: Investigate and determine the road sections prone to waterlogging, determine the scope of waterlogging impact, delineate the scope of road reconstruction based on the scope of waterlogging impact, and conduct additional road surface design for the road reconstruction scope, design the set color, and design the set reflectivity; construct additional road surface by spraying and painting in the areas prone to waterlogging; When the additional road surface performs both warning and anti-skid functions: Determine and calculate the depth and range of water accumulation in areas prone to water accumulation under rainfall intensity; calculate the thickness of additional anti-skid pavement at rainy day running speed; construct additional pavement with set color, set reflectivity and set thickness by spraying, painting and other processes in areas prone to water accumulation; When the additional road surface performs the three functions of warning, anti-skid and drainage: The thickness of the solid hydroskiing front line 4 and the intermittent hydroskiing front line 3 is calculated according to the depth of the accumulated water, the marking width and interval width of the solid hydroskiing front line 4 and the intermittent hydroskiing front line 3 along the vehicle driving direction are calculated according to the influence range of the accumulated water, the gap width and the marking segment inclination angle between several marking segments of the intermittent hydroskiing front line 3 are calculated, and the use mode and combination ratio of the solid hydroskiing front line 4 and the intermittent hydroskiing front line 3 are obtained; Mill and reconstruct the longitudinal markings on both sides of the road in the area affected by waterlogging, and construct drainage marking line 1; The solid hydroskiing front tyre line 4, the intermittent hydroskiing front tyre line 3 and the drainage marking line 1 are constructed in the water-prone area of the road section, and there are certain intervals between the solid hydroskiing front tyre lines 4 and the intermittent hydroskiing front tyre lines 3, and the intervals are connected with the drainage gaps of the drainage marking lines 1 on both sides.
[0026] Furthermore, the physical hydroplaning tire line 4 is arranged perpendicular to the driving direction, and the marking width of the physical hydroplaning tire line 4 along the vehicle driving direction is calculated according to the design speed of the road section and the depth of water accumulation; There is a spacing distance between the several marking sections of the intermittent hydroplaning tire line 3, and the spacing distance is calculated comprehensively according to the depth of water accumulation in the road section, the design speed of the road section and the drainage distance, and the maximum width of the spacing distance is less than the minimum tire width of the vehicle passing through the road section; The physical width, spacing and inclination of several marking segments perpendicular to the direction of vehicle travel are calculated based on the composite slope of the road section, the vehicle running speed and the depth of water accumulation; The width of the discontinuous hydroplaning line 3 along the vehicle's driving direction is calculated based on the road section design speed and the depth of water accumulation. Furthermore, the distance between the solid hydroplaning line 4 and the intermittent hydroplaning line 3 along the vehicle travel direction, as well as the number and ratio of the solid hydroplaning line 4 and the intermittent hydroplaning line 3, are calculated based on the design speed of the road section and the depth of water accumulation; The thickness of the solid hydroplaning line 4 and the intermittent hydroplaning line 3 are calculated based on the longitudinal slope, transverse slope, water depth and design speed of the road section. Specifically, the thickness of the solid hydroplaning line 4 and the intermittent hydroplaning line 3 is greater than the maximum water depth minus the tire water breaking depth at the design speed of the road section. Furthermore, when the setting area of the solid hydroplaning line 4 and the intermittent hydroplaning line 3 contains a lane dividing line and a lane edge line, the lane dividing line and the lane edge line are constructed as the drainage marking line 1, and the drainage gap of the drainage marking line 1 is set at an acute angle to the driving direction in the extension direction away from the road surface.
[0027] Although the above describes the specific implementation mode of the present invention in conjunction with the accompanying drawings, it is not intended to limit the scope of protection of the present invention. Those skilled in the art should understand that various modifications or variations that can be made by those skilled in the art on the basis of the technical solution of the present invention without creative work are still within the scope of protection of the present invention.
