Definitions
- the invention relates to a method for de-icing carriageways onto which a thawing agent for lowering the freezing point is applied. Furthermore, the invention relates to a device for deicing roadways, on the course of which organs for applying a thawing agent and drainage channels for draining off the water are attached.
- a thawing agent consisting of salt is generally applied, which lowers the freezing point of the water, so that the ice is already at relatively deep Temperatures are melting.
- a disadvantage of this method is that it consumes a relatively large amount of salt that is lost after use. This not only results in cost disadvantages, but also has a damaging effect on the environment. Especially in the case of so-called whisper asphalt, the consumption of thawing agent is disproportionate due to the open-pore road surface. " T high.
- the invention is based on the object of demonstrating a method for de-icing roadways which considerably reduces the consumption of thawing agents, so that not only can the costs be reduced but also the environmental impact is noticeably reduced.
- this object is achieved according to the invention in that the thawing water running off the roadway is collected and at least partially reused for deicing.
- the running and collected defrost water generally consists of a salt solution, the concentration of which allows reuse as a thawing agent. This has the advantage that not only the pure salt consumption can be significantly reduced, but that at the same time a saving in equipment and personnel costs for winter service is made possible.
- the defrosting water is checked with regard to its defrosting agent content. If the thawing water concentration of the thawing water is very low, it can be drained into a receiving water, while if the concentration is sufficient, it is reused for deicing.
- the defrosting water is checked again in terms of its thawing agent content before it is sprayed onto the road again, so that a desired target concentration can be set.
- the invention is also intended to achieve the object of providing a device for de-icing roadways of the structure outlined at the beginning, with the aid of which the method according to the invention can be carried out. According to the invention, this object is achieved in that the run-off channels lead along the carriageway into at least one catch basin, which is connected to the organs for applying the thawing agent.
- catchment basins for waste water are being planned and installed more and more frequently, especially on motorways, in order to be able to isolate the waste water in the event of accidents, additional construction costs are limited in the implementation of the device according to the invention. It is sufficient to lead a return line from the respective collecting basin to the organs for applying the thawing agent, generally spray nozzles, via which the reused thawing agent (saline solution) is sprayed onto the road again.
- thawing agent saline solution
- a switch is provided which is connected to a first sensor for measuring the concentration of thawing agent and which, if the concentration is too low, discharges the thawing water into a receiving water and if the concentration is sufficient, it is discharged into the collecting basin.
- a switch connected to a second sensor for measuring the concentration of de-icing agent can be connected to the removal line of the collecting basin leading to the organs for applying the de-icing agent and connects the sampling line to the organs for applying the de-icing agent at the desired concentration while opening a feed line for supplying water or defrosting agent at a different concentration.
- FIG. 1 shows a cross section through a roadway, along which the device for performing the method is provided
- Figure 2 is a schematic plan view of the roadway with the device according to the invention.
- a roadway 10 is shown with edging 12 (curbs) on both sides, wherein the cross slope of the roadway 10 can be seen in FIG.
- the street wastewater runs behind the border 12 on the right in the figures into drainage ducts 14 which are connected to a common drainage channel 18 via drainage channels 16.
- the drainage channel 18 leads into a collecting basin 20;
- several dearfing basins 20 are provided at intervals, so that oil-containing water can be drained off in a controlled manner, for example in the event of accidents with tankers.
- the catch basins 20 are connected to a receiving water in a manner not shown.
- FIG. 2 shows that a first sensor 22 is installed between the collecting basin 20 and the drainage channel 18, which sensor can actuate a changeover valve. If the sensor 20 detects a too low concentration of de-icing medium, it switches the valve so that the waste water is discharged into the receiving water connected to the drainage channel 18, while at a higher concentration which allows the condensation water to be reused, the valve is switched so that the defrost water is drained into the catch basin 20. From the collecting basin 20, a removal line 26 connected to a suction pump 24 leads to a switch 28 which is controlled by a second sensor.
- the switch 28 is connected via a line 30 to a feed pipe 32 to which a plurality of organs 34 (spray nozzles) for applying the thawing agent to the roadway 10 are connected.
- the switch 28 is also connected to an intermediate container 36 which contains a highly concentrated thawing agent solution and / or water.
- the sensor connected to the switch 28 measures the thawing agent concentration of the reused thaw water before it reaches the organs 34 (spray nozzles). If the actual concentration deviates from the target concentration, highly concentrated de-icing agent solution or water is fed via the switch 28 to the defrost water before being passed on to the line 30 until the target concentration is reached. Only then is the switch 28 switched and passed on to the line 30 and from there to the organs 34.
- the device can be automated by sensors which measure the temperature and the humidity of the ambient air, so that the suction pump 24 and the switch 28 connected to the second sensor are automatically switched on when there is a risk of slippage.
