As shown in FIG. 9, the slip prevention road surface construction method using the road surface non-slip groove forming tool according to the present invention includes a base mold construction step S100, a construction space partition step S200, a packaging material installation step S300, The surface forming step S500, the first formwork demolishing step S600, and the second form demolishing step S700 may be performed.

First, in the basic mold construction step S100,

As shown in FIG. 10, a step of forming a construction space 11 by constructing a foundation form 10 based on a construction area of a road to be constructed, wherein the foundation form 10 is formed as an entire circumference of a construction area .

Thereafter, a construction space dividing step S200 is performed,

11, the construction space 11 formed in the above-described manner is formed in a lattice shape having a predetermined size.

At this time, the construction space 11 is divided into a plurality of rows and columns by using a lattice-shaped die 20 having a plurality of rows of horizontal bars 21 and a plurality of rows of vertical bars 22, As shown in Fig.

The lattice form 20 is preferably formed on the upper part of the foundation form 10 so as to be spaced apart from the bottom of the construction space 11 so that the construction space 11 can be divided into sections And the lower part of the partitioned space 11 is communicated with each other to form one space 11.

Thereafter, a packaging material installation step (S300) is performed,

This is because the road pavement 30 is installed in the construction space 11 partitioned as shown in Fig. 12, and the road pavement 30 is installed immediately before the top of the foundation pavement 10, The space communicated at the lower part of the upper part 11 and the space partitioned by the upper lattice type mold 20 are installed.

13, the upper surface of the road wrapping material 30 is flattened by using a normal flat roller 40, and the upper surface of the road wrapping material 30 is pressed with a predetermined pressure And pressure rolling is performed.

At this time, it is preferable to perform the planing work in a state where about 60 to 70% of the installed road wrapping material 30 is cured. If the road wrapping material 30 is cured below the reference level, 30 is too thin and partially pressed too much, the flattening operation can not be carried out. If the curing is performed in a state of being cured more than the reference value, the excessive curing proceeds and the pressing of the surface becomes impossible. Since it is performed at the reference value, a smooth pressing force is applied to the upper surface of the road wrapping material 30, so that the planarization is facilitated.

Thereafter, the surface forming step S500 is performed,

This is achieved by using the road surface non-slip groove forming tool 1 of the present invention, as shown in Fig. 14, in which the road wrapping material 30 is carried out before curing in succession to the surface planarization work, .

This replacement of the molding tube 310 can be performed by using It will be possible depending on the location and environment to be constructed.

That is, when the vehicle is installed on a relatively sloping or curved road surface, the slip during running of the vehicle is relatively increased. In this case, the molding tube 310, which forms the molding protrusions 312 and 312 ' The relatively large slip prevention grooves 50 and 50 'are formed, so that it is easy to cope with slowing down and slipping of the vehicle. On the relatively flat or straight road, relatively small shaped molding protrusions 312 The molding tube 310 constituting the sliding doors 312 and 312 'is applied to form the dense non-slippery grooves 50 and 50', thereby minimizing interference with the ride feeling when the vehicle is traveling.

In addition, the various polygonal shapes of the molding protrusions 312 and 312 'will enable the molding of the anti-slip grooves 50 and 50' in various patterns depending on the environment in which the molding is performed.

In addition, when the molding tube 310 is used as described above, when the same load is applied according to the size of the molding protrusions 312 and 312 'of the molding tube 310, When a relatively large molding protrusion 312 or 312 'is applied, a plurality of weight bodies 350 and 350' are attached to the weight body insertion grooves 326 and 326 'of the weight shaft 320 A small number of weights 350 and 350 'can be mounted and used when the small molding protrusions 312 and 312' are applied. In addition, Therefore, the weight reduction and the load are reduced, so that the pressure molding can be smoothly performed.
