Description

Road structure to prevent fine dust and its construction method

According to the present invention, it is possible to more easily prevent the generation of fine dust in the air without the operation of a car or train having a separate fine dust collecting plate installed, and also to prevent the black ice phenomenon, and furthermore, it is possible to prevent 2 It is possible to prevent a car accident, and also relates to a fine dust prevention road structure that is easy to replace and repair, and a construction method thereof.

In general, there is a lot of fine dust on the road on which a car travels or a railroad on which the subway runs, and this is emerging as a major problem in modern times because there is a component harmful to the car or train and the human body.

In other words, fine dust is one of numerous air pollutants along with sulfur dioxide, nitrogen oxide, lead, ozone, carbon monoxide, etc. Fine dust with a particle diameter of 10 μm or less that floats for a long time is called PM10, and when the particle size is 2.5 μm or less, it is called 'fine dust (PM 2.5).

Fine particles are also called suspended particles, particulate matter, or aerosol, and have slightly different meanings depending on their names.

Particulate matter has a particle diameter (diameter) of about 10 nm to 100 μm, and when the particle diameter is larger than this, the residence time in the atmosphere is very short due to the sedimentation effect by gravity.

In addition, the fine dust penetrates deeply into the human alveoli, and the fine dust accumulated in the bronchial tubes and lungs directly causes various respiratory diseases, lowers the body's immune function, causes asthma and breathing difficulties, and causes long-distance movement in rain or snow. It also increases the concentration of heavy metals.

In order to remove such fine dust, recently, a method and device for removing fine dust from a road or railroad that can remove fine dust from a road or railroad, thereby reducing environmental pollution caused by fine dust, and the device are disclosed in Korean Patent Laid-Open No. It has been proposed as No. 10-2013-0107783.

However, in the Korean Patent Laid-Open Publication No. 10-2013-0107783, a separate fine dust collecting plate is installed and operated in a car or train to remove fine dust from a road or railroad, so a separate fine dust There are problems in that it is cumbersome to install a collection plate on a car or train, and when a car or train with a separate fine dust collection plate installed does not operate a road or railroad, it is impossible to remove fine dust from the road or railroad.
