Description

Precast concrete module for road paving and road paving method using same {PRECAST CONCRETE MODULE FOR PAVING OF ROAD AND METHOD OF PAVING ROAD USING THE SAME}

In Korea, where there are four distinct seasons and many mountainous terrains, traffic is disrupted in mountainous areas and uphill roads due to heavy snowfall in winter, cold freezing due to cold weather, or partial freezing of road surface due to lack of sunshine on roads in shaded areas. Events and accidents are frequently occurring. However, as a method of removing snow and freezing on the road, a large amount of calcium chloride spraying, road snow removal or freezing using expensive imported machinery is generally used, but these methods are used for ex post measures, not for precautions. Because it is a corresponding method, it causes only a huge increase in socio / economic costs and is not an efficient method of removing snow or ice. Moreover, in the case of the method of spraying large amounts of calcium chloride, it is known that calcium chloride remaining on the road after work has a serious adverse effect on the natural environment located along the road. It is not a desirable method.

As a method of constructing a building structure, the application field is being attempted from various angles.

Accordingly, the present invention is to reduce the road paving period by applying the above-described precast concrete method to the road paving field, as well as technical background to efficiently remove or prevent snow and frost on the road surface in winter. To be released under

The technical problem to be achieved by the present invention is a prefabricated road paving, can be a tensile coupling to withstand the shear stress generated at the top according to the use of the road, in winter to remove snow and ice on the road surface Another object is to provide a precast concrete module having a means for preventing it.

Another technical problem to be achieved by the present invention is to provide a road paving method using the precast concrete module.
