Description

The invention relates to a drainage channel for surface drainage of roadways and an arrangement comprising one or more such drainage channels and a roadway. The invention further relates to a method for producing such a drainage channel and a method for applying a road marking.

Such drainage channels for surface drainage of roadways, in particular roadways in tunnel structures, the drainage channel being designed and/or provided at least in sections as a base for a roadway marking, have a longitudinally extending channel body with a receiving space for receiving a liquid to be discharged, the receiving space is delimited by two oppositely arranged side walls, a base and a gutter head, the gutter head having at least one, preferably two, side sections extending in the longitudinal direction.

Roadways are understood to mean, in particular, roadways, preferably in road tunnels.

In tunnel construction, especially in tunnel construction for road tunnels, the inside of the tunnel wall is usually followed by a walkway and/or escape route, a drainage channel and then the roadway. The edges of the road are usually marked by road markings. Since there is always a desire to save space in tunnel construction, there is a desire to arrange road markings next to the road, at least in sections. This means that the road marking should be placed on the drainage channel.

However, the problem is that when the road marking is renewed, the old road marking has to be removed, for example by milling. If this road marking is now on the drainage channel, removing the old road marking can lead to significant damage to the drainage channel.

The invention is therefore based on the object of providing a new drainage channel, in particular a drainage channel in which the problem of damage when renewing the road marking is at least largely avoided. Furthermore, it is the object of the invention to provide an arrangement comprising one or more such drainage channels and a roadway which avoids the aforementioned problem. In addition, a new manufacturing process for such drainage channels as well as a new process for applying road markings should be specified.

The task is solved with regard to the drainage channel by the subject matter of claim 1, with regard to the arrangement by the subject matter of claim 10, with regard to the manufacturing process by the subject matter of claim 12 and with regard to the method for applying a road marking by the subject matter of claim 14.
