Description

How to lay the press {METHOD OF PAVING SIDEWALK}

The present invention relates to a method for laying a sidewalk, and more particularly to a method for laying a sidewalk for walking.

In addition to the sidewalks along the roads, the city has many types of pedestrian walks, including park trails and squares. There are many types of paving stones on the sidewalk. Conventionally, sand layers were laid on the ground to a predetermined thickness, and paving stones were placed on the sand layers. Most conventional paving stones are concrete materials.

Conventionally, only sand was laid as a support layer for paving stones. For this reason, when the temperature is lowered below freezing in winter, there is a problem that the sand layer is frozen, the ground is weakened and even settled. In addition, since the sand layer is lost during rainfall, there is a problem that the lost portion is settled.

In addition, the paving stone and sand layer of the concrete material to block the inflow of surface water into the basement, there was a problem in reducing the amount of groundwater. In addition, since the pollutants in the surface to be discharged directly into the river, it has been a cause of water pollution.

In particular, the radiant heat emitted from the paving stone and sand layer of the concrete material is very large, there is also a problem that the pedestrians who walk on the paving stone in the summer feel more severe heat. Radiant heat exacerbates urban heat islands.

Therefore, the present invention was devised to solve all the problems of the conventional paving method, do not freeze in winter, the amount of radiant heat is reduced in summer, and the surface water can be introduced into the underground The purpose is to provide.

According to the present invention for achieving the above object, the sidewalk laying method is a base layer for freezing prevention consisting of crushed stone having a particle size of 40-50mm on the ground to 10-20cm thick, 19-25mm particle diameter on the lower base layer Laying a subsidiary base layer of crushed stone to a thickness of 10 to 12 cm, and laying an upper base layer consisting of crushed stone having a particle diameter of 2 to 5 mm on the auxiliary base layer to a thickness of 5 to 8 cm, while natural stone is processed into a rectangular parallelepiped shape. It is arranged in the upper base layer at regular intervals horizontally, and between each paving stone half filled with crushed stone having a particle diameter of 2-5mm, and the other half filled with stone powder.

In addition, the sidewalk laying method according to the present invention, if the place where the ground is subjected to a lot of load, it is also possible to interpose the mat between the lower base layer and the auxiliary base layer, laying the mat on the upper base layer without placing the paving stone directly on the upper base layer After the adhesive is applied to the mat, the paving stones can be glued to the mat, and instead of the adhesive method, anchors can be installed on each paving stone, and the paving stones can be installed by hanging the anchors on the mat. And L-shaped supports are provided on both sides of the sidewalk, and paving stones are placed within the supports.

And, the present invention, by laying the lower base, the auxiliary base and the upper base in sequence, and placing the paving stone in the upper base layer, the support base of the paving stone is greatly strengthened. Therefore, the phenomenon that soil sediment is lost at the time of rainfall or frozen in winter is suppressed. In addition, since the upper base layer having a very small particle diameter is installed very thinly, the surface water can easily penetrate underground.

Hereinafter, a preferred embodiment of the sidewalk laying method according to the present invention will be described in detail with reference to the accompanying drawings.

Example 1

1 is a cross-sectional view showing a sidewalk laying method according to a first embodiment of the sidewalk laying method according to the present invention. A preferred embodiment 1 of the sidewalk laying method according to the present invention, as shown in FIG. Lay various layers consisting of three layers underneath. That is, the lower base 10, the auxiliary base 20 and the upper base 30 are sequentially installed from the ground, and the paving stones 40 are disposed on the upper base 30 at regular intervals.

Subsequently, the lower base layer 10 is a layer for preventing freezing in winter, and a plurality of crushed stone having a particle diameter of 40 to 50 mm is laminated to a thickness of 10 to 20 cm to form a freeze protection layer 10. That is, since the particle size of the crushed stone used in the lower base layer 10 is large, the spaces present between each other are large, and the phenomenon of freezing of the crushed stone by winter is suppressed.

Subsequently, the auxiliary base layer 20 is laid on the lower base layer 10, and a plurality of crushed stones are also used for the auxiliary base layer 20. The crushed stone used in the auxiliary base 20 is smaller than the crushed stone particle size used in the lower base 10. That is, the crushed stone for the auxiliary base layer 20 has a particle size of 19 to 25 mm, and a plurality of such crushed stones are laminated in a thin layer having a thickness of 10 to 12 cm in thickness of the lower base layer 10, thereby laying the auxiliary base layer 20. .

The upper base 30 is then laid on the auxiliary base 20. The upper base layer 30 is a kind of sand layer conventionally used, and is formed by laying a plurality of crushed stones having a particle diameter of 2 to 5 mm in a very thin thickness of 5 to 8 cm.

Subsequently, the paving stone 40 processed to a predetermined size by natural stone, such as granite or limestone, is disposed on the upper base layer 30 at a vertical and horizontal interval therebetween, and then, between each of the paving stones 40, the finish stone 50 and the lime powder (60). Fill with). The finish stone 50 fills about half of the depth between each paving stone 40, and a crushed stone having a particle diameter of about 2 to 5 mm is used. The other half is filled with stone powder (60). Finishing stone (50) and stone powder (60) serves to prevent the flow of paving stone (40) and increase permeability.

Then, the stone powder 60 on the surface of the paving stone 40 is finally combed so as to enter between each paving stone 40, and the stone powder 60 protruding above the surface of the paving stone 40 is removed. If the surface of the paving stone (40) is dirty, clean it with water.

Example 2

Figure 2 is a cross-sectional view showing a sidewalk laying method according to a second embodiment of the present invention. As a sidewalk laying method according to a second embodiment of the present invention, as is different from the first embodiment, the lower base layer 10 The first mat 70 is interposed between the auxiliary base layer 20 and the auxiliary base layer 20.

That is, the first mat 70, which is made of synthetic resin such as polyester or wire mesh, is laid on the lower base layer 10, and the auxiliary base layer 20 is laid on the first mat 70. The thickness of the fiber yarn used for the first mat 70 is about 3 to 5 mm, and the interval is about 25 mm.

This installation method can be applied to a place that receives more load than the place where the first embodiment is constructed, for example, a plaza, playground or parking lot.

Example 3

3 is a cross-sectional view showing a sidewalk laying method according to a third embodiment of the present invention. A method for preventing the flow of the sidewalk laying method press according to the third embodiment of the present invention and a method for shortening the construction cost are provided.

That is, the first mat 80 made of polyester is laid on the surface of the upper base layer 30, and the adhesive 90 is applied to the second mat 80. Then, the paving stones 40 are adhered to the second mat 80 through the adhesive 90. With this progress, the paving stones 40 are not simply located on the upper base layer 30, but the second mat. Since it is adhesively arrange | positioned at 80, the flow of each paving stone 40 can be prevented more firmly. On the other hand, it is more preferable to fill between the finishing stones 50 and the stone powder 60 between each paving stone 40.

In particular, in Example 1, since a large number of paving stones 40 are to be arranged by the operator at the top and bottom substrates 30 one by one, the labor cost is high, and thus, the construction cost burden is a concern. After manufacturing the second mat 80 of a predetermined size, and after adhering the paving stones 40 to the second mat 80, the second mat 80 is simply laid on the upper base 30 in the field Therefore, there is an effect that can reduce the construction cost.

Example 4

4 is a cross-sectional view showing a sidewalk installation method according to a fourth embodiment of the present invention. In the fourth embodiment, a wire anchor 100 is used instead of the adhesive used in the third embodiment. The upper end of the anchor 100 is fixed to the bottom surface of the paving stone 40, and is wound one time at the lower end to form a circle. The lower end of the anchor 100 is sandwiched between the second mat 80. When the fiber yarn of the second mat 80 passes between the circles formed at the lower end of the anchor 100, the paving stone 40 is firmly supported by the second mat 80. Between each paving stone 40 is also filled with a finish stone (50) and stone powder (60).

Example 5

5 is a cross-sectional view showing a sidewalk installation method according to a fifth embodiment of the present invention, Figure 6 is a perspective view showing a support used in the fifth embodiment.

The press installation method according to the fifth embodiment of the present invention is different from the first embodiment of the present invention in that the support 110 is used, as shown in FIG. 5. The support 110 is applied to a park walkway with many curved parts.

That is, the support 110 is made of an L-shaped metal plate, such as aluminum. Supports 110 having such a shape are disposed on both sides of the upper base layer 30, and are fixed to the pins 120. Therefore, the park walkway and the grass formed in the park are distinguished by both support members 110. The paving stones 40 are arranged at regular intervals inside the support 110. Then, each paving stone 40 is supported by both support bases 110, so that the paving stones 40 can be more firmly held in place than the first embodiment. have. Of course, if the same method as in Embodiments 3 and 4 is used, it is not necessary to use the support 110. Subsequent installation methods are the same as those in Example 1, and the description thereof will be omitted.

However, the support 110 should be disposed along the curved surface as described above, and since its material is a metal such as aluminum, a structure that enables bending can be formed in the support 110. That is, if the L-shaped support 110 is divided into a side plate portion and a bottom plate portion, a substantially triangular bent groove 111 is continuously formed in the bottom plate portion. Each of the bending grooves 111 supports the support 110 in various curvatures. It can be arranged along the curved surface having a. Of course, the bending groove 111 may be formed in a different shape, such as a semi-circular shape.

On the other hand, in order to strengthen the strength of the support 110, it is preferable to form a bead 112 in each of the side plate and the bottom plate.

As described above, in the sidewalk laying method according to the present invention, since the base layer is composed of three layers composed of crushed stone having different particle diameters, the ground of the paving stone is strengthened. Therefore, ground subsidence is suppressed. In particular, since the lower base layer is composed of crushed stone having the largest particle size, the space is large between each other, and freezing is suppressed.

In addition, since each of the paving stones is filled with a finish stone and stone powder, the situation that the soil of the upper base layer is lost by the rainfall is also prevented. In particular, since the upper base layer has a very thin thickness, surface water can be easily absorbed underground. That is, the installation method according to the present invention has the advantage of very excellent water permeability.

In addition, since the natural stone is used as the paving stone, radiant heat is smaller than that of the conventional concrete paving stone, so that the heat felt by the pedestrian is reduced and the urban heat island phenomenon is also suppressed.

On the other hand, the present invention is not limited to the above-described specific preferred embodiments, and various changes can be made by those skilled in the art without departing from the gist of the invention claimed in the claims. will be.
