Description

Grooving construction device for road surface}

The present invention relates to a technology for preventing a vehicle from slipping on an automobile road, and more particularly, a road configured to form a plurality of grooves on a road surface at once using a manual facility equipped with cutting wheels at regular intervals. It relates to surface grooving construction equipment.

In general, in the case of a sloped road or a section requiring a predetermined braking force, a function for preventing a safety accident of a running vehicle by suppressing a slip phenomenon of the road surface is required.

Considering this, anti-skid materials are installed on downhill or curved roads to increase the friction coefficient between the vehicle tires and the road surface, thereby inducing drivers passing this area to slow down and keeping the vehicle balanced. Accidents can be prevented in advance.

In general, in order to prevent slipping on the road surface, aggregates such as silica sand, quartz, glass beads, bauxite, steel slugs, etc. are mixed with flooring paint such as thermoplastic resin, and then applied to the road surface to form a concave-convex surface or grooving ) By forming grooves at regular intervals based on the construction method, the driver's safe driving is induced.

This grooving method is applied to prevent slipping or aquaplaning, suppress ice, improve drainage, and improve driving safety, and is generally divided into dry and wet grooving methods. The double dry grooving method can be performed at almost 40% of the construction cost compared to the method of applying a resin-based non-slip material, so it is economical and has a long lifespan, and as in the wet grooving method, it does not use water, so there is no contamination. It is widely used because it does not generate water and does not require equipment for water supply.

Regarding the grooving method for preventing slipping of the road surface as described above, Korean Patent Registration No. 1020485 discloses a permeable water-repellent coating composition and a road surface groove construction method using the same, and Patent Registration No. 1462203 discloses an anti-slip groove. An eco-friendly surface curing and waterproofing agent composition and a construction method using the same are disclosed.

In addition, in the case of Registered Patent No. 0910647, multi-line cutting blades are installed to allow grooving construction to be performed on roads with many lanes. However, since the cutting blades are assembled to a circular driving shaft, frictional heat is generated while sliding on the driving shaft during construction work. This occurs, and there is a risk that the cutting blade is bent or easily worn.
