Description

Double structure lane and construction method thereof

The present invention relates to a lane and a construction method thereof, and more particularly, to a double-structured lane and a construction method thereof, which allow a driver to easily identify an area with a lane even if a painted lane on a road is damaged.

In general, lanes for guiding the driving of the vehicle are formed by painting on the road surface of the road on which the vehicle travels. Among these lanes, a center line or an edge lane is formed as a continuous line (straight line), and a lane between them is formed as a dividing line (dotted line).

The lanes formed by painting are worn out due to weather, the passage of time, friction with the tires of a driving vehicle, etc., resulting in lane damage such as finally peeling off the road.

It would be desirable if the lane repair work was carried out quickly when the lane damage occurred, but in reality, the repair work is performed after a certain period of time has elapsed after the lane damage has occurred. Due to this, since lane identification is not easy on a road section in which lane damage has occurred, the probability of occurrence of a traffic accident due to lane damage may increase.

Registered Patent Publication No. 10-0832110 (2008.05.27. Announcement)

Accordingly, it is an object of the present invention to provide a double-structured lane and a construction method thereof, so that a driver can easily identify an area with a lane even if the painted lane is damaged.

Another object of the present invention is to provide a dual structure lane and a construction method thereof, which can easily perform the construction work of the lane.

In order to achieve the above object, the present invention provides a lane area in which a plurality of grooves are formed in a longitudinal direction in which lanes are to be formed on the surface of a road; a plurality of safety lines formed by inserting resin wires into the plurality of grooves, respectively; and lanes formed in the lane area with paint to cover the plurality of safety lines.

The safety line is inserted into the groove, the resin wire positioned below the surface of the road; a primer applied on the resin wire; and a glass grain applied on the primer.

The primer is filled between the resin wire and the groove to fix the resin wire in the groove.

At least one of the plurality of grooves is formed as a discontinuous groove in the longitudinal direction in which the lane is to be formed, and the resin wire is inserted into each of the discontinuous grooves.

At least one of the plurality of grooves is formed as a continuous groove in the longitudinal direction in which the lane is to be formed, and the resin wire is inserted into the continuous groove in the longitudinal direction.

The present invention also includes the steps of forming a plurality of grooves in a longitudinal direction in which lanes are to be formed in a lane area of a road surface; forming a plurality of safety lines by inserting a resin wire into each of the plurality of grooves; and forming lanes with paint in the lane areas to cover the plurality of safety lines.

The forming of the plurality of grooves may include: forming a base line with paint in the lane area in a longitudinal direction in which the lane is to be formed; and forming the plurality of grooves along the base line.

The forming of the plurality of safety lines may include: inserting the resin wire into the plurality of grooves to be positioned below the surface of the road, respectively; applying a primer on the resin wire inserted into the groove; and applying glass grains on the primer.

The inserting may include: mounting the resin wire having a diameter corresponding to the width of the groove on the groove; pushing the resin wire into the groove with a cylindrical roller with a smooth rotating surface; and pressing the resin wire inserted into the groove with a compaction roller having a plurality of protrusions corresponding to the plurality of grooves on the rotating surface to be positioned below the surface of the road and into the groove.

The forming of the plurality of safety lines may include: inserting the resin wire having a cross-sectional size smaller than that of the groove into the groove, and inserting the resin wire to be positioned below the surface of the road; fixing the resin wire in the groove by applying a primer to the groove into which the resin wire is inserted; and applying glass grains on the primer.

According to the present invention, after forming a plurality of grooves in the lane area, forming a plurality of safety lines to be filled in the plurality of grooves, respectively, and then forming the lanes covering the plurality of safety lines with paint, even if the painted lanes are damaged The plurality of safety lines may allow a driver to easily identify a lane area.

When constructing the double structure lane according to the present invention, the safety line can be easily performed because the safety line is installed in a way that is inserted or inserted into the groove formed in the lane area.

The safety line inserts a resin wire into the groove, applies a primer on the resin wire inserted into the groove, and applies a glass grain on the applied primer, so that even if the painted lane is peeled off and the safety line is exposed on the surface of the road, Through the retroreflection through the applied glass grain and the color (fluorescence) of the resin wire, the driver can more easily identify the lane area.

By applying a primer to the resin wire inserted into the groove after inserting the resin wire into the groove, the primer fills the space that may be formed between the groove and the resin wire, so that the resin wire inserted into the groove is stably fixed in the groove can do it

Since the safety wire is based on the resin wire, the resin wire inserted into the groove can be easily separated, thereby making it easy to replace the safety wire without damaging the road base material.

Since the safety line is formed with a narrow width below the lane, the safety line minimizes road damage and does not affect the road aesthetic at all.

Since the safety line is formed under the lane, the dual structure lane according to the present invention is the same as the existing lane in appearance, so that it is possible to provide the driver with the same riding comfort as the existing one.

Since the groove forming the safety line is formed narrowly, when it is necessary to change the lane of the road and construct it, it can be done through a simple measure of filling the groove with the road base material, and the cost of restoration is small.

And even if the safety line is exposed to the outside due to damage to the lane among the double structure lanes, the groove in which the safety line is formed is formed narrowly. also rarely occurs.
