Spraying system capable of regulating temperature and melting ice and snow based on permeable pavement

Abstract

The invention relates to the technical field of municipal engineering, and discloses a permeable pavement-based temperature regulating and ice and snow melting spraying system, which comprises a deceleration strip pressurizing device, a temperature sensing valve I, a waterproof thin layer, a nozzle, a pressure storage device, a temperature sensing valve II, a snow melting agent box, a triplet floating ball valve, a water storage tank, a filter bag, a water collecting and shunting pipeline and a waterproof bonding layer, the speed bump pressurizing device extrudes air to pressurize the pressure storage device through the pressure of a vehicle on the speed bump, then the pressure is released to the water storage tank to extrude water into the pipeline to be sprayed to the road surface, water is sprayed in summer and snow melting agents are sprayed in winter, and spraying is not conducted at the normal temperature. The self-temperature-sensing, self-spraying, self-collecting and self-draining road surface cooling and ice and snow melting device has the characteristics of self-temperature sensing, self-spraying, self-collecting and self-draining, and can flexibly cool the road surface and melt ice and snow with less manpower.

Problems solved by technology

[0002] At present, with the construction of sponge cities, municipal roads mostly use permeable asphalt pavement to prevent urban waterlogging, and set up purification and collection devices under the road surface or change the structure under the road surface to initially filter and then collect and discharge rainwater. However, these methods have not The collected water is used and the surface structure of the driveway is changed, which will affect the performance of the road surface. The road surface needs to be dug in the later maintenance, which has a great impact on vehicle traffic

[0003] The asphalt pavement needs to be sprayed with water to cool down in summer. At present, the sprinkler is generally sprayed along the road by manually driving the sprinkler, which cannot cool down the whole road section in time. After the permeable asphalt pavement is sprayed, the water will penetrate the pavement, making the water on the pavement evaporate faster. The cooling time is short, and it is necessary to drive the sprinkler several times to spray. There are also roads where motor pumping and spraying are installed under the road surface. However, this method is expensive and cannot be used on a large scale. The nozzles installed on the road surface are easy to be damaged. Maintenance and replacement of equipment need to destroy the road surface and interrupt traffic.

[0004] In winter, snow and ice will appear on the road, which will reduce the friction of the road surface. At this time, the road needs to be cleaned of ice and snow to prevent slipping. The current methods are mostly manual or mechanical deicing and snow removal, but such methods are inefficient and time-consuming. , another commonly used method is to spray deicing agent, but the same method can not spray deicing agent on the whole road section at the same time, and because the deicing agent will melt the ice and snow on the road surface and bring the deicing agent to penetrate the road surface, resulting in the concentration of deicing agent on the road surface reduce the effect, and there are also a small number of roads where motors are installed to spray deicing agent under the road surface, but the same method is costly and inconvenient to maintain
