DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Referring to the drawings, an embodiment of the present invention will be described in detail. FIG. 1 and FIG. 2 show an artificial ski slope sliding mat 10 according to the present invention.
Is composed of a mat body 14 formed by combining a plurality of plastic pipes 12 in a mat shape, and these plastic pipes 14 have irregularities 16 on the surface. The plastic pipe 12 is preferably made of polyethylene which is excellent in elasticity, impact resistance and abrasion resistance, and is also slippery.

The plastic pipe 12 is shown in FIGS.
Has a trapezoidal cross section, a circular cross section as shown in FIG. 4, a semicircular cross section as shown in FIG.
May have an arbitrary cross-sectional shape such as a triangular cross-section shown in FIG. Further, as shown in FIG. 4, a cross-shaped thin reinforcing rib 18 that is continuous in the longitudinal direction or provided at intervals in the longitudinal direction may be provided on the inner peripheral surface.

In the illustrated embodiment, as shown in FIGS. 1 and 3, a plurality of elastic rubber or plastic spacers 20 are interposed between the plurality of plastic pipes 12 at longitudinal intervals. Further, these plastic pipes 12 are combined in a mat shape by a connecting member 22 such as a wire. This connecting member 22 is used to fix the sliding mat 10 by fixing it to a pile driven into the ground when the mat is later laid on an artificial ski resort. The diameter of the plastic pipe 12 and the distance between adjacent plastic pipes can be set as appropriate according to the purpose of use. In particular, where there is a lot of snow, it is preferable to increase the interval between the plastic pipes 12 so that the snow does not slide down.

The irregularities 16 on the surface of the plastic pipe 12
As shown in FIG. 2, a plurality of ring-shaped protrusions 24 formed at intervals in the longitudinal direction of the plastic pipe 12 are provided.
And the depressions 26 between the adjacent projections 24, but the irregularities 16 can be formed in other appropriate forms. The unevenness 16 has a function of adjusting the coefficient of friction of the mat.

8 Therefore, after laying the sliding mat 10 on the artificial ski resort, each plastic pipe 12 can be connected to a water pressure feed source, and the sliding mat itself can also serve as a water spray device.

As shown in FIG. 3, when the plastic pipe 12 has a water puddle 30 formed around the sprinkling hole 28, the water puddle 30 can improve the sliding of the sliding mat 10.

Since the sliding mat 10 of the present invention is in the form of a blind, it can be rolled and transported to a laying site, but can be spread and laid at the laying site. This run mat is used to form a runway for a normal artificial ski resort by laying it on a sloped mountainous area, but it is installed as a lifter road instead of a lifter beside the landing path of the jumping area or the runway. May be. The lifter path is used by skiers to climb up the runway by the endless belt, which is installed beside it and is always driven.

Each plastic pipe 12 is shown in FIG.
As shown in FIG.
It is connected to the. The water supply tank 34 is located at a position higher than the plastic pipe 12, and the water in the water supply tank 34 is fed to the plastic pipe 12 using a head. Therefore, plastic pipe 1
The water supplied to 2 can be spouted from the sprinkling holes 28 to improve the sliding of the sliding mat 10.
