Abstract

PURPOSE:To permit golf playing even in the snowfall period by a method in which the tee is covered with a vinyl house and an underground heating facility is provided in a given size of area and green area and its neighbor in the direction of playing at each striking point of fairway. CONSTITUTION:In case of middle hole, an underground heating facility in fairway is provided in the area of 40m widths 120-180m before tee and before and back the dropping point of tee shot. In case of long hole, the heating facility is provided in the area of about 40m widths 240-300m from tee in the second striking point. The underground heating facility is provided by forming a porous material heat insulator layer 2 of a thickness of 5-10cm in the ground 10 of 40-60cm depth from the ground's surface. Plying golf can thus be made even in the cold snowfall area in the winter season while keeping turf fresh green.

Description

DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) The present invention relates to golf course equipment that allows golf course equipment to be played even under snowfall or snow cover.

(Prior art) In conventional golf courses, golf play becomes difficult when it snows, so the golf course is temporarily closed and waiting for the snow to melt, or the snow is removed mechanically, so that the game can be resumed somehow. However, in areas with heavy snowfall, they were forced to close for months, which not only led to a loss of players, but also meant that expensive equipment was out of commission during the shutdown.

(Problem to be solved by the invention) The present invention is intended to solve the above-mentioned conventional problems.
The objective is to provide a golf course that can be played in the winter even in areas with heavy snowfall by installing large vinyl greenhouses and underground heating equipment at places essential for playing the golf course.

(Means for Solving the Problems) The golf course of the present invention covers the tee with a large vinyl house at a golf course in a cold region or a region with heavy snowfall, and places the golf course at a place corresponding to the breaking point of the fairway in the direction of play. The area is approximately 60 to 120 meters in length, and is characterized by the fact that underground heating equipment is installed for snow melting in an area of approximately 40 meters in length, as well as in Clean and surrounding areas, and the snow is compacted around these areas. do.

The vinyl house installed on the tee according to the present invention can be assembled and
It is meant to be a simple building that can be easily removed, and any structure that can be used for similar purposes in addition to conventional greenhouses is fine.

In the present invention, the underground heating equipment area installed in the fairway is more specifically the area before and after the landing point of the tee shot (120 to 180 m in front of the tee, width of about 40 m) in the case of middle holes, and the area of long holes. In this case, in addition to the area mentioned above, the second hitting point (240 ~
The area at 360m is approximately 40m wide.

Underground heating equipment for snow melting to be installed in the above areas, clean areas, and surrounding areas can be similar to those conventionally installed on pavements in snowy regions for the purpose of snow melting. For example, you can install hot water pipes, or use heat-generating sheets such as rubber sheets or plastic sheets with built-in nichrome wires. These heating devices are buried at an appropriate depth in the area to be heated. When burying, a suitable insulation material is placed on the bottom surface, a heat insulating material is placed on the top surface, and culture soil is layered on top, so that the appearance is the same as a normal fairway or clean.

In areas other than the above-mentioned areas where underground heating equipment has been installed, areas where golf balls are likely to fall, such as the areas mentioned above and around the green, should be compacted to prevent falling balls from becoming deeply embedded in the snow. Make it.

(Example) An embodiment of the present invention will be described below with reference to the drawings.

Figure 1 shows a large plastic greenhouse installed on the tee.

Usually, there are 3 to 4 tees per hole, with an area of 300 mm.
Set up a ~500rn' tee and hit the first shot of play. There is no need to use the entire surface, so 1~
Two sides, 100 to 300 rn', with a height of 5 to 10 cm, with the frontage facing the clean room as wide as possible.
rn', cover it with a large plastic greenhouse with a depth of 10 to 15 m. The materials used should be those that can withstand snowfall, and the roof should have a slope sufficient to allow snow to fall from side to side.

FIG. 2 is a schematic diagram showing underground heating equipment installed in a clean area. Even in areas other than the green, basically,
Either use the same equipment as shown in this figure, or use simpler equipment such as making the top soil roughly thinner.

The underground heating equipment shall be constructed as follows.

Land 1 at a depth of 40 to 60 cm below the ground surface in the area where the equipment will be installed
A heat insulating layer 2 made of a porous material such as pumice gravel and having a thickness of 5 to 10 cm is formed at the point 0 to reduce the loss of heating heat. A wire mesh 3 for fixing hot water pipes is laid on top of the wire mesh 3 with openings of 25 to 40 cm, and a synthetic resin hot water pipe 4 with a diameter of 20 to 30 mm is arranged on the upper surface to serve as an underground heating source. On top of that, a gravel layer 5 with a thickness of 15 to 20 cm is placed as a layer for diffusion of heat rise and underground water permeability, and on top of that, a sand layer 6 made of sand or sandy soil as a rhizosphere is placed 15 to 20 cm thick.
Backfill to a thickness of 20 cm and cover with turfgrass culture soil. In order to hold the ball and obtain a denser turf on the top layer of the green, top soil with a thickness of 3 to 10 cm is evenly spread along with base fertilizer to form the turfgrass planting bed 7. Note that a net 8 may be placed between the gravel layer 5 and the sand layer 6 if necessary. In the figure, 9 indicates turfgrass.

In this example, the heat source used was hot water, electricity,
Gas is very effective. Furthermore, in addition to synthetic resin tubes with low specific conductivity as a heat medium, heating can also be done by passing through steel tubes whose surface is coated with synthetic resin, and even ceramic acid tubes that emit infrared and far-infrared radiation.

As a heat supply source, it is recommended to install a boiler as close as possible to each facility location, install insulated piping in the vicinity of the boiler using a main pipe, and use a circulating hot water supply system.

The golf course constructed as described above was playable even during the winter snowy period as well as during the normal season, and the golf course was in good condition.

(Effects of the Invention) According to the present invention, it becomes possible to play golf in cold and snowy regions, where golf play has been forced to be interrupted, closed, or closed under snowfall or snowfall. In addition, the fresh greenness of the turf grass is not affected even in the winter, making it possible to operate throughout the year and play on a high-quality turf field.
