Embodiment Construction

[0031] Pores or voids that occur during production in the base region of the seal in the prior art are well visible in FIG. 1 . The defect impairs the leak-tightness in the transition joints between the individual channel bodies.

[0032] figure 2 An example according to the invention for a drainage channel with a guide section 10 and a functional area 11 is shown. in accordance with figure 2 In the preferred embodiment, the guide section 10 is a channel body through which liquid, especially water, flows in use. The functional section 11 is at the end of the drainage channel and acts as a seal. Such gutters are used, for example, for surface drainage of streets.

[0033] The invention is not restricted to drainage channels, but can also be used for other liquid-conducting devices, in which local functional areas, ie, for example well-tight sealing areas, should be formed with optimized properties.

[0034] according to figure 2 The guide section 10 is formed from polymer...

Abstract

The invention relates to a device for guiding liquid, in particular a drainage channel, comprising a guiding section (10) and at least one functional region (11), wherein the guiding section (10) is formed of concrete, which has a binder and a filler having a first grain size K1, wherein the functional region (10) is formed at least partially of a filled reaction resin, which has a filler having asecond grain size K2, wherein K2<K1.

Description

technical field [0001] The invention relates to a device for conducting liquid, in particular a drainage channel, having the features stated in the preamble of claim 1 , and to a method for producing such a device. Background technique [0002] A device of this type is known from EP 0 556 533 A1. [0003] In order to also form a fluid-tight channel branch line in the passage region between the channels, which is formed from a plurality of drainage channels arranged one behind the other, a sealing medium can be introduced between two channels in this region . For this purpose, the transition joints can be filled with sealing material at the construction site in order to create a fluid-tight connection between the drainage channels. However, it is also possible to use prefabricated seals which are arranged on the groove body. For this purpose, special geometries for receiving the seal are generally required on the groove body. [0004] It has been shown that a specific geo...
