Description

Automatic control type cooling clean road system and method {COOLING CLEAN ROAD SYSTEM AND CONSTRUCTION METHOD THEREOF}

The present invention relates to an automatically controlled cooling clean road system and method, and more particularly, to an automatically controlled cooling clean road system and method that is installed on a road and automatically removes fine dust or harmful substances by spraying water onto the road surface. it's about

In general, fine dust is one of the major air pollutants, and harmful substances such as sulfur oxides, nitrogen oxides, volatile organic compounds, and heavy metals are attached to the particle surface, and by depositing in the alveoli or bronchi, it seriously harms human health.

Among the fine dust, the dust accumulated on the pavement is re-scattered due to the operation of the vehicle is called "road re-scattering dust". Road ash scattering dust is deposited and accumulated on the road surface due to various causes such as direct emission from vehicle exhaust gas, wear of automobile tires and road surfaces, automobile brake pad wear dust, falling dust, garbage, mud and dust, etc. It is caused by re-scattering due to the movement of the vehicle. In order to reduce such road material scattering dust, conventionally, a method of spraying water on the road surface while operating a dedicated water cleaning vehicle has been widely used.

However, the road surface sprinkling method using a vehicle has a weakness in that it is necessary to visit a water source frequently during cleaning to secure water. In addition, since the water cleaning vehicle has to operate at a low speed during cleaning, there is a risk of interfering with the operation of other vehicles. .

As a technique proposed to solve the above problems, in Patent Document 1, cleaning water containing heavy water and/or groundwater is stored and installed underground, and one end is connected to the storage tank and the other end is above the center of the pavement surface. A water pipe connected to the water pipe and extending along the traveling direction of the vehicle under the central part of the pavement surface, one end connected to the water supply pipe and the other end extending above the central part of the pavement surface, in the longitudinal direction of the water supply pipe A plurality of branch pipes spaced apart from each other, a plurality of spray nozzles connected to the branch pipes to spray cleaning water perpendicular to the traveling direction of the vehicle, and a storage tank to control the flow pressure of cleaning water and the spray pressure of the spray nozzles There is disclosed an automatic water cleaning device for paved roads having a pressure pump to provide.

However, the conventional automatic water cleaning device on paved roads did not collect foreign substances or air contained in heavy water, so that the injection nozzle was clogged or the injection pressure was lowered, which made it inconvenient to use in the field. Since the nozzles have to be fastened using tools one by one, the fastening time takes a long time, which increases the fastening cost, and in order to water the road, the person in charge has to go to the site to check the watering and then operate it, which is inconvenient to use at the site.

As an alternative, as disclosed in Patent Document 2, a technique for removing dust or foreign substances from the road surface by spraying a washing solution or calcium chloride solution using a spray nozzle fused to a road sign installed on the road surface has been proposed. Road signage is a safety device that is installed on the median dividing line, lane boundary, or around a crossing, and identifies the lane to the driver at night or on cloudy days, thereby inducing traffic safety and smooth flow of vehicles.

The injection nozzle, etc., which is fixedly installed on the road surface, can be remotely controlled by communicating with a remote control device of a central control room at a remote location through a predetermined control panel installed at a predetermined location. To this end, a valve box for controlling the injection nozzles individually or by zone is installed on the road or around the road. A communication card for connecting each injection nozzle to the control panel, including a control valve connected to the injection pipe, is installed inside the valve box.

However, the conventional communication card installed in the valve box has a problem in that the circuit board is exposed to moisture in the environment installed in the valve box, so that an electric leakage, short circuit, noise, or the like occurs easily, or a communication error occurs.
