Description

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

The present invention relates to an automatic control type cooling clean rod system and method, and more particularly, to an automatic control type cooling clean rod system and method that is installed on the road and automatically removes fine dust or harmful substances by spraying water onto the road surface. 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 surface of the particles, and by depositing in the alveoli or bronchi, it causes serious harm to human health.

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

However, the road sprinkling method using a vehicle has a vulnerability that requires frequent visits to the water source during cleaning to secure water. In addition, since the water cleaning vehicle must operate at a low speed during cleaning, there is a concern that it may interfere with the operation of other vehicles, and since it is difficult to clean the lower part of the vehicle parked on the road using a vehicle, there is a disadvantage that an additional manpower must be added. .

As a technology proposed to solve the above problems, Patent Document 1 includes a storage tank that is stored and installed underground, and one end is connected to the storage tank, and the other end is upper side down to the center of the pavement surface. The water supply pipe extended to and connected to the water supply pipe and extended along the direction of the vehicle under the central part of the pavement, one end connected to the water supply pipe, and the other end extended to the upper side of the central part of the pavement, and the longitudinal direction of the water supply pipe A plurality of branch pipes spaced apart from each other, a plurality of sprinkling nozzles connected to the branch pipes and spraying cleaning water perpendicular to the traveling direction of the vehicle, and a storage tank are connected to control the fluid pressure of the cleaning water and the sprinkling pressure of the sprinkling nozzle. An automatic water cleaning device is disclosed on a pavement provided with a pressure pump provided.

However, the conventional automatic water cleaning device for paved roads has a problem that it is inconvenient to use in the field because the spray nozzle is clogged or the spray pressure decreases due to the inability to collect foreign substances or air contained in heavy water. Since the nozzle must be fastened with a tool one by one, fastening time takes a long time to increase fastening cost, and there is a problem that it is inconvenient to use in the field because the person in charge must go to the site to check the spraying one by one and then operate it to spray the road.

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 liquid or calcium chloride solution using a spray nozzle fused to a road marking bottle installed on the road surface has been proposed. A road sign is a safety device that is installed at the center of the road, at the boundary of a lane, or around a crossing, and induces traffic safety and smooth flow of vehicles by identifying the lane to the driver at night or on a cloudy day.

The spray nozzle or the like fixedly installed on the road surface may 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 for each area is installed on the road or around the road. In the inside of the valve box, a communication card for connecting each injection nozzle to the control panel, including a control valve connected to the injection pipe, is installed.

However, in the conventional communication card installed in the valve box, the circuit board is exposed to moisture due to the environment installed in the valve box, so that there is a problem that a short circuit, short circuit, noise, etc. or communication error occurs, and thus a countermeasure is required.

The automatic control cooling clean rod system according to the present invention is operated as a clean rod spraying system that uses water from groundwater or rainwater storage tanks in summer, and in winter, snow that accumulates on the road in winter because a snow removal agent such as calcium chloride is contained in the clean road water. It can be operated as a salt water spray system for preventing road icing that melts.

The water supply pump 104 is connected to the discharge part of the storage tank 100 through a predetermined pipe to pump the liquid discharged from the storage tank 100 at a predetermined flow rate and pressure. It is preferable that the feed water pump 104 is provided with at least two and one of the two serves as an auxiliary pump.
