Description

Pavement temperature control automatic spray cooling system based on rainwater collection

technical field

The utility model relates to the field of rainwater collection, in particular to a road surface temperature control automatic spray cooling system based on rainwater collection.

Background technique

With the rapid progress of urbanization, there are more and more hardened urban roads, and the corresponding urban green area is also less and less. Most of the green areas, wetlands, ditches and other areas with the function of water conservation in the natural state have evolved into hardened roads. As a result, the city can only rely on the municipal pipe network for drainage when facing heavy rainfall. On the one hand, this drainage method has a higher design standard for the municipal pipe network; Because for most cities, the groundwater is generally short of water due to the large number of people who need to be supplied; in view of the above situation, my country first proposed the concept of "sponge city" in 2012, and put forward new ideas for the construction of urban roads. Require. The so-called sponge city is a new generation of urban stormwater management concept, which means that the city has good elasticity in response to natural disasters brought by rainwater, and can have good elasticity like a sponge. Conservation of rainwater.

On the other hand, in most parts of our country, the maximum temperature in summer can reach above 35-40°C, and the maximum temperature of the general asphalt pavement is 25°C higher than the maximum temperature, and may reach above 60-65°C. The softening point of asphalt is generally between 40 and 55°C. In summer, the temperature of asphalt pavement can easily reach above the softening point. In addition, the high temperature lasts for a long time, and the asphalt pavement will be deformed and damaged rapidly under the action of heavy traffic. The work of dust prevention mainly adopts the method of artificial watering, which not only wastes water resources, but also has many negative problems such as safety and economy.
