JP 2011-30674 A

The conventional weed control sheet as described above is composed of a non-woven fabric made of synthetic fibers such as polypropylene and polyester, and its thickness is about 0.5 mm at most. Therefore, although the installation work is easy, the effect of improving the sliding property on the snow mat cannot be expected.

The present invention has been made in view of such circumstances, and its main object is to provide a weed control mat that contributes to the improvement of sliding properties on a snow mat, and a method for installing the same.

In order to solve the above-mentioned problems, a weed control sheet according to one aspect of the present invention is a flat plate-shaped weed control mat, made of expandable resin, and laid on the ground of a ski slope and the ground. It is interposed between the snow mat.

It should be noted that each embodiment shown below is an example of an apparatus and method for embodying the technical idea of the present invention, and the technical idea of the present invention is not limited to the following. do not have. Various modifications can be made to the technical idea of the present invention within the technical scope described in the claims.

(Structure of weed control mat)
FIG. 1 is a perspective view showing the structure of the weed control mat of this embodiment, and FIG. 2 is a plan view showing the structure. 1 and 2, each direction of the weed control mat is indicated by an arrow. The weed control mat 1 has a flat mat body 10 that is square in plan view. The mat body 10 is a 1 m square flat plate. However, it is not limited to this size.

The mat body 10 is made of foamed resin. As this foamable resin, for example, polyethylene foamable resin can be used. The thickness of the mat body 10 is about 15 mm. Although the thickness of the mat body 10 is not limited to this, it is preferably 10 mm or more and 50 mm or less as described later.

The mat body 10 is provided with a plurality of cylindrical holes 11 penetrating in the front and back direction (vertical direction). These holes 11 are formed at predetermined intervals over the entire surface of the mat body 10 . The diameter of the hole 11 is approximately 10 mm.

FIGS. 1 and 2 show an example in which seven hole rows each including five holes 11 arranged in the left-right direction are arranged side by side in the front-rear direction. Therefore, a total of 35 holes 11 are formed in this example. In addition, the rows of holes adjacent to each other in the front-rear direction are formed with a slight deviation in the left-right direction.

As described above, in the present embodiment, a total of 35 holes 11 are formed in the mat body 10, but the number is not limited to this. determined as appropriate. Moreover, the interval between the adjacent holes 11, 11 may not be constant. Furthermore, various embodiments are conceivable, such as the holes 11 need not be formed over the entire surface of the mat body 10, and may be formed only in the central region of the mat body 10 or its peripheral region.

FIG. 3 is a perspective view showing the structure of the anti-grass mat 1 laid on the ground of a slope of a ski resort. Also, FIG. 4 is a side view showing a partially enlarged structure of the weed control mat 1. As shown in FIG. As shown in FIG. 3, a plurality of weed control mats 1 are laid on the ground 3 of the slope in a row in the front, rear, left, and right directions. FIG. 3 shows an example in which a total of nine weed control mats 1 are laid, three in the front-rear direction and three in the left-right direction, but the number and arrangement are not limited to this. is of course.

As shown in FIGS. 3 and 4 , snow mats 2 are laid on the plurality of weed control mats 1 . In FIG. 3, a part of the snow mat 2 is shown cut away. In general, the snow mat 2 has an uneven structure periodically formed on its surface in order to reduce the friction of the ski, and furthermore, a plurality of holes penetrating in the vertical direction are formed in order to obtain water permeability. However, in FIGS. 3 and 4, illustration of the concave-convex structure and holes is omitted. Similarly, in FIG. 5, which will be described later, illustration of the uneven structure and holes is omitted.

As described above, the weed control mat 1 is laid on the ground 3 of the slope, and the snow mat 2 is further laid thereon. That is, the weed control mat 1 is interposed between the ground 3 of the slope and the snow mat 2 laid on the ground 3 .

By providing the weed control mat 1 in this manner, the ground 3 is blocked from being exposed to sunlight. This suppresses the growth of weeds on the ground 3 and prevents the grown weeds from reaching the snow mat 2 . Therefore, it is possible to prevent situations such as the weeds impairing the grip of the ski and making it difficult to remove the snow mat.

Note that if the diameter of the hole 11 formed in the mat body 10 is large, there is a risk that grown weeds will reach the snow mat 2 through the hole 11 . On the other hand, if the diameter of the hole portion 11 is small, drainage performance is impaired. Therefore, the diameter of the hole 11 is preferably 5 mm or more and 50 mm or less.

Further, since the mat main body 10 of the weed control mat 1 is made of foamed resin, it has cushioning properties. Therefore, compared with the case where the snow mat is laid directly on the ground of the slope and the case where the snow mat is laid on the conventional weed control sheet laid on the ground, the snow mat is provided with cushioning properties. be able to. When cushioning properties are imparted in this manner, the ski can be flexed, making it easier to bend, thereby improving the skiing performance. In addition, the foamable resin provides an appropriate resilience, so further improvement in gliding performance can be expected. In addition, by obtaining cushioning properties, it is possible to reduce the impact when the skier falls. Therefore, it is possible to improve safety.

In the case of this embodiment, since the mat body 10 has a thickness of about 15 mm, it is possible to sufficiently maintain the above cushioning properties. If the thickness is less than 10 mm, the weed control effect can be expected to some extent, but there is a problem that the cushioning property is deteriorated. On the other hand, if the thickness exceeds 50 mm, although the cushioning property is sufficient, problems arise such as the shape of the ground not being followed and construction being difficult. Therefore, the thickness of the mat body 10 is preferably 10 mm or more and 50 mm or less.

Further, since the mat main body 10 is provided with a plurality of holes 11, the weed control mat 1 has water permeability. Therefore, it is possible to ensure drainage performance in rainy weather. When the holes 11 are provided at regular intervals as in the present embodiment, the drainage is not biased, which is preferable. Furthermore, in the case of the present embodiment, since the holes 11 are formed over the entire surface of the mat body 10, uneven drainage can be further eliminated.

Since the mat main body 10 is made of foaming resin, the weed control mat 1 has a heat insulating property. Therefore, when there is accumulated snow on the snow mat 2, the weed control mat 1 can also exhibit the effect of preventing snow melting. Moreover, since the snow-melting water is discharged from the holes 11, it is possible to prevent the snow-melting from being accelerated by the snow-melting water. Therefore, it is possible to reduce the burden of slope management.

(Weed control mat construction method)
Hereinafter, the construction method of the weed control mat 1 will be described with reference to FIGS. 5A to 5D.
First, as shown in FIG. 5A, a plurality of weed control mats 1 are laid side by side on the ground 3 of the slope. At this time, the adjacent weed control mats 1, 1 are arranged with a slight separation (for example, about 10 mm). As a result, a gap is formed between the weed control mats 1, 1 after construction, so that drainage is improved.

Next, as shown in FIG. 5B, snow mats 2 are laid on the plurality of weed control mats 1 . FIG. 5B shows an example in which three weed control mats 1 and one snow mat 2 have the same width (the width in the left-right direction in the drawing), but this is not the only option. Instead, the widths of these may be different.

Next, as shown in FIG. 5C, a driving pin 4 is driven from above the snow mat 2 in the direction of the arrow. The region where the driving pin 4 is driven may be the edge region of the snow mat 2 as shown in FIG. 5C, or may be another region. In any case, a plurality of driving pins 4 are driven. The area in which the driving pins 4 are driven and the number of driving pins 4 are appropriately determined according to the size of the snow mat 2 and the like. As the driving pin 4, various known ones can be adopted.

FIG. 5D shows a case where the tip of the driving pin 4 reaches the ground 3 through the weed control mat 1. FIG. By driving the driving pins 4 to this depth, not only the snow mat 2 but also the anti-grass mat 1 can be fixed to the ground. This facilitates construction of the weed control mat 1 .

Note that, as in the example shown in FIG. 5D, some of the plurality of weed-control mats 1 laid on the ground 3 (weed-control mats located at both left and right ends in the drawing) are snow-resistant. While the mat 2 is fixed to the ground 3 , the rest of the weed-control mat 1 (the weed-control mat located in the center in the drawing) does not have to be fixed to the ground 3 with the driving pins 4 . Driving the driving pins 4 into all the weed-control mats 1 not only increases the work load, but also all the weed-control mats 1 are pressed against the ground 3 by the snow mats 2 and fixed. It is because there is little need. In addition, if the weed control mat 1 is fixed by the driving pins 4 , the cushioning properties and the like are impaired, although only slightly.

(Other embodiments)
In the above embodiment, the mat body 10 of the weed control mat 1 is formed with the holes 11, but these holes may not be formed. Even in that case, if there is a gap between the laid weed control mats 1, 1, a certain degree of drainage can be obtained.

The shape of the mat body 10 of the weed control mat 1 is not limited to a square, and any shape such as a rectangle or a polygon can be adopted.
