Description

[0001] The present invention relates to an arrangement according to the preamble of claim 1, a method for manufacturing an arrangement according to claim 9 and a method for applying a road marking according to claim 10.

[0002] Such an arrangement is known from CN107419640A, CH698270B1, DE8706254U1 or US2017 / 191233A1.

[0003] The term "roadways" refers in particular to roadways, preferably in road tunnels.

[0004] In tunnel construction, particularly for road tunnels, the tunnel wall is typically followed on the inside by a pedestrian and / or emergency exit, a drainage channel, and then the roadway. The edges of the roadway are usually marked by road markings. Since space is always a priority in tunnel construction, there is a desire to place road markings, at least in sections, alongside the roadway. This means that the road markings should be placed on top of the drainage channel.

[0005] However, the problem is that renewing the road markings requires removing the old ones, for example by milling. If these road markings are located on the drainage channel, removing them can cause significant damage to the channel.

[0006] The invention therefore aims to provide a new arrangement that largely avoids the problem of damage during the renewal of road markings. Furthermore, it aims to provide a new manufacturing process for such arrangements and a new method for applying road markings.

[0007] The problem is solved with regard to the arrangement by the subject matter of claim 1, with regard to the manufacturing method by the subject matter of claim 9, and with regard to the method for applying a road marking by the subject matter of claim 10. Advantageous embodiments and further developments are specified in the respective dependent claims 2-8, 11.

[0008] The advantage of the drainage channel according to the invention is in particular that, when the road marking is renewed, only the protective and / or sacrificial material is damaged to a large extent, whereas the drainage channel itself remains at least predominantly free from any damage, since direct contact of the channels with a removing tool or vehicle is avoided by means of the protective and / or sacrificial material in the recess.

[0009] Preferably, the receiving chamber has an oval cross-section, tapering in one direction from the channel head to the bottom of the channel body. In other words, the cross-section is egg-shaped with the point facing downwards.

[0010] It may be provided that a receiving channel for receiving cables extends longitudinally L and / or parallel to the receiving space through the channel body, in particular through one of the side walls of the channel body.

[0011] According to the invention, the recess is, in particular completely, filled with a protective and / or sacrificial material as a substrate for the road marking, wherein the protective and / or sacrificial material is preferably cast into the recess.

[0012] According to a preferred embodiment of the invention, the channel head has two opposing side sections extending in the longitudinal direction, wherein a first side section of the two side sections is arranged adjacent to the roadway in the installed state of the drainage channel, and wherein the recess is arranged in the first side section.

[0013] The term "installed state" refers in particular to a state in which the drainage channel is arranged parallel and / or adjacent to the roadway, for example, laid down. It is especially preferred that the drainage channel, in its installed state, is arranged between a roadway and a pedestrian and / or emergency access route and / or a curb, for example, laid down.

[0014] The side sections can be connected by webs, with a slot provided between each pair of longitudinally adjacent webs, preferably allowing a liquid to flow from the surface into the receiving chamber through the slots. Nubs can be provided on the upper surface of the webs.

[0015] Alternatively, the channel head can be closed. This means, in particular, that the channel head has no slots or other openings for draining water from the top of the channel body.

[0016] A second side section, positioned opposite the first, can form a cantilever. In its installed state, the second side section preferably abuts a pedestrian walkway and / or escape route and / or a curb. The cantilever extends, in particular, beyond the top surface of the walkways. Furthermore, the cantilever may be designed with an undercut on its outer side surface, especially to save material.

[0017] Preferably, the recess is formed in a stepped shape, with the recess extending into the side section from an outer side surface and from a top surface of the side section.

[0018] Preferably, the recess of the drainage channel, when installed, abuts the roadway. Furthermore, the depth of the recess may correspond to the thickness of the road surface, in particular the thickness of the asphalt.

[0019] The protective and / or sacrificial material is or preferably comprises mastic asphalt or concrete. The channel body is, for example, made of concrete, in particular polymer concrete. If the channel body is made of concrete or polymer concrete, the protective and / or sacrificial material differs from the material of the channel body, with mastic asphalt preferably forming the protective and / or sacrificial material. If the channel body is made of a material other than concrete, the protective and / or sacrificial material may be concrete.

[0020] The arrangement according to the invention comprises one or more drainage channels according to the invention and a roadway, wherein the drainage channel or the multiple drainage channels are arranged parallel and / or adjacent to the roadway, preferably laid, wherein the side section with the recess is arranged adjacent to the roadway.

[0021] If several drainage channels are provided, they are arranged in a series in such a way that a continuous channel is formed through the receiving spaces of the drainage channels.

[0022] According to the invention, a protective and / or sacrificial material is provided in the recess of the drainage channel or drainage channels, wherein the protective and / or sacrificial material borders the roadway.

[0023] Preferably, the roadway has a layered structure with at least two, preferably three, layers, the uppermost layer being the road surface, in particular asphalt. The thickness of the protective and / or sacrificial material of the drainage channel or multiple drainage channels preferably corresponds to the thickness of the road surface.

[0024] According to the inventive method for producing an arrangement according to the invention, a longitudinally extending channel body is produced, in particular cast in a mold, wherein the channel body is designed such that the channel body has a receiving space for receiving a liquid to be discharged, wherein the receiving space is limited by two oppositely arranged side walls, a bottom and a channel head, and wherein the channel head has at least one longitudinally extending side section.

[0025] Either a recess is formed on the side section during the manufacture of the channel body, for example by providing a suitable mold or insert in the mold, or the recess is introduced into the side section after the manufacture of the channel body, for example by milling.

[0026] According to the invention, a protective and / or sacrificial material is introduced into the recess, in particular cast in.

[0027] According to the inventive method for applying a road marking, an arrangement is first provided, wherein the arrangement comprises one or more drainage channels according to the invention and a roadway, wherein the drainage channel or the multiple drainage channels are arranged parallel and / or adjacent to the roadway, preferably laid, wherein the side section with the recess is arranged adjacent to the roadway, wherein a protective and / or sacrificial material is provided in the recess of the drainage channel or drainage channels, wherein the protective and / or sacrificial material is adjacent to the roadway.

[0028] Subsequently, a road marking is applied to the arrangement in such a way that the road marking is arranged section by section on the roadway and section by section on the protective and / or sacrificial material of the drainage channel.

[0029] Preferably, the road marking is renewed, in particular completely, by removing the area of ​​the roadway and the protective and / or sacrificial material bearing the road marking, in particular by milling, and then applying a second road marking in such a way that the second road marking is arranged section by section on the roadway and section by section on the protective and / or sacrificial material of the drainage channel.
