However, if, as this is often used to improve hydraulic properties, the cross-sectional profile is V-shaped rather than semi-circular, the seal is bent to a greater extent, which leads to poor performance over longer periods of use. Sealing and breaking

Embodiment Construction

[0024] In the following description, the same reference numerals are used for identical and identically acting components.

[0025] from according to Figures 1 to 3 The perspective view of the exemplary embodiment shown here shows that the drainage channel 10 has side walls 11 , 12 and a bottom 13 as well as end walls 14 and 15 . The interior or the bottom of the drainage channel 10 is denoted by reference number 16 . At the first end 17 , the seal 30 is connected to the drain channel 10 , more precisely via fastening legs 31 which lie in corresponding slots in the drain channel 10 , which will be described in more detail below. The seal 30 has an outer sealing lip 32 and an inner sealing lip 33 . It is also possible to dispense with the sealing lip 32 so that the base body of the seal is in contact with the bearing surface 41 .

[0026] A sealing strip 40 is provided on the second end 18 , said sealing strip having an inwardly directed bearing surface 41 . If two gutters...

Abstract

The invention relates to a gutter element for draining, for example, road surfaces, which can be joined together to form a line of guttering. In order to seal off the connection, an elastic seal (30)is provided in the abutment region. In order to improve the hydraulic properties of the gutter, the cross-sectional profile of the invert (16) of the gutter (10) is substantially V-shaped. To improvesealing, the profile following the seal (30) in cross-section should be formed differently to that of the invert (16) in such a way that it has a constant maximum radius of curvature in the region ofthe gutter invert.

Description

technical field [0001] The invention relates to a drainage channel according to the preamble of claim 1 for eg drainage of road surfaces. Background technique [0002] Increasing demands are placed on such gutters that the gutter line itself is generally sealed. This means that the connections between the individual gutter elements must be airtight. For this purpose, as is shown, for example, in DE 41 28 068 A1 or DE 20 2009 017 312 U1, seals are inserted or injected between mutually adjoining gutter elements. The seal requires that the end faces of the gutters adjoining each other be secured together. [0003] When the seal is inserted, then in known gutters the protective groove for the seal follows the cross-sectional profile of the gutter interior. In the case of the aforementioned gutter, this is not a major problem, since a relatively large radius of curvature is provided according to the interior space profile. However, if, as this is often used to improve hydraul...
