Device for guiding liquid and production method
View Patent ↗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 K 1 , wherein the functional region ( 11 ) is formed at least partially of a filled reaction resin, which has a filler having a second grain size K 2 , wherein K 2 <K 1 .
1. A drainage channel for guiding liquid, the drainage channel comprising a guiding section ( 10 ) for guiding the liquid and functional region ( 11 ), the functional region ( 11 ) bonded on an end of the guiding section ( 10 ), wherein the guiding section ( 10 ) is made from concrete that contains a binding agent and a filler with a first grain size K 1 , and wherein the functional region ( 11 ) is made at least partially from a reactive resin with a filler with a second grain size K 2 , wherein K 2 <K 1 .
2. The drainage channel according to claim 1 , wherein the second grain size K 2 is at most 1 mm, wherein grain size is determined by a test following standard EN ISO 1524.
3. The drainage channel according to claim 1 , wherein the functional region ( 11 ) has a surface roughness k [mm] of 0.02 to 0.05.
4. The drainage channel according to claim 1 , wherein the concrete is a polymer concrete.
5. The drainage channel according to claim 4 , wherein the binding agent of the concrete and the reactive resin consist of the same thermoset resin.
6. The drainage channel according to claim 4 , wherein the concrete is provided with a binding agent proportion H 1 and the reactive resin is provided with a binding agent proportion H 2 , wherein H 2 >H 1 .
7. The drainage channel according to claim 6 , wherein the binding agent proportion H 2 is greater than 20% by weight.
8. The drainage channel according to claim 4 , wherein the guiding section ( 10 ) and the functional region ( 11 ) are firmly bonded.
9. The drainage channel according to claim 8 , wherein the functional region ( 11 ) forms a layer of the reactive resin with filler, disposed on the guiding section ( 10 ) made from concrete.
10. The drainage channel according to claim 9 , wherein the thickness of the layer of the reactive resin with filler is less than 2 mm.
11. The drainage channel according to claim 8 , wherein the functional region ( 11 ) is a molded part ( 12 ) made from the reactive resin with filler, the cross-sectional shape of the molded part ( 12 ) conforms to the cross-sectional shape of the guiding section ( 10 ) made from concrete, wherein the molded part ( 12 ) and the guiding section ( 10 ) are in alignment.
12. The drainage channel according to claim 1 , wherein the functional region ( 11 ) forms a seal for joining the guiding section ( 10 ) to further channel element.
13. A method for the production of the drainage channel for guiding liquid according to claim 1 , in which the reactive resin with filler in the form of a paste is applied to the guiding section ( 10 ) made from concrete to form the functional region ( 11 ) and then the paste is cured.
