Hybrid grooving head, and grinding method monitoring system for noise reduction and road driving improvement using the same}

The present invention relates to a hybrid grooving head, and a grinding method monitoring system for reducing noise and improving road drivability using the same. It is a hybrid grooving head that not only reduces the temporal and material cost, but also contributes to the safety part, compared to grinding construction by manpower by introducing and applying the 4th industrial revolution technology artificial intelligence and hyper-connected system. , It relates to a grinding method monitoring system for noise reduction and road driving performance improvement using the same.

In general, highways or automobile-only roads are divided into asphalt paved roads and concrete paved roads. Asphalt pavement has a disadvantage of having a low construction cost and good ride comfort, but due to its weak strength, there are many road damages during use, and accordingly, frequent repair work is required. In addition, concrete pavement has the advantage that construction costs are high and ride comfort is low, while its strength is strong, so that road damage is less when used, and thus maintenance costs are low.

These concrete pavements have made continuous efforts to reduce noise and improve ride comfort in order to improve the driving comfort of highway users, but they still generate relatively high driving noise compared to asphalt pavements, so various types of surface treatment are being performed.

Accordingly, in the surface treatment of concrete pavement, it solves environmental noise pollution by reducing tire-road friction noise, improves flatness, improves driving comfort, increases slip resistance, secures safety, and extends the common life of concrete pavement. There is a need for technology development to be effective in reducing maintenance costs.

Meanwhile, in order to improve the noise and ride comfort of conventional concrete pavement, grooving and diamond grinding are performed, and in the case of grooving, higher noise is still generated than asphalt pavement. It shows a marked difference from the low-noise asphalt pavement.

For example, FIG. 1 is a view for explaining a transverse and longitudinal grooving method according to the prior art, and FIG. 1A shows transverse grooving, and FIG. 1B shows longitudinal grooving. 1A and 1B, grooving refers to making a groove by cutting the surface of a concrete pavement or asphalt concrete pavement using cutting equipment.

This grooving method is a method of forming grooves of a certain standard on the pavement surface of roads and runways, and according to the definition of the International Grooving and Grinding Association (IGGA), pavement texture ), it is divided into texture and groove according to the width of the unit pattern. That is, the case where the width (space) of the unit pattern is 1/2 inch (12.7 mm) or more is defined as a groove, and the case where the unit pattern is less than 1/2 inch is classified as a texture.

This grooving method is classified into Longitudinal Grooving, which cuts the groove horizontally with the vehicle driving direction, and Transverse Grooving, which cuts vertically to the vehicle driving direction according to the classification by pattern.

In the case of Korea, as shown in FIG. 1A, only the transverse grooving 30 has been applied until now, but in recent years, the longitudinal grooving 40 as shown in FIG. 1B is effective in reducing the accident rate and reducing noise.

Fins and lands are formed on the concrete pavement by the conventional diamond grinding (CDG) method, and the noise between the concrete pavement road surface and the tire according to this is as shown in FIG. 2A.
