Description

DETAILED DESCRIPTION OF THE INVENTION [Purpose of the Invention] (Industrial application field) The present invention is to provide a ground, a course such as an athletic field, a stadium, a golf course, etc., regardless of seasons and weather fluctuations throughout the year. The present invention relates to an all-weather maintenance method using a composite buried pipe for maintenance so that it can be used under optimum conditions.

(Prior art) As is well known, the grounds of athletic fields and stadiums become soft and muddy when the rainfall is severe, and on the other hand, if the sunny weather continues for a long time, they will dry and dry and dust will fly up. To prevent muddy ground, most sports grounds and stadiums buried perforated pipes for drainage in the ground to improve drainage. This is handled by means of installing sprinklers and other watering equipment.

(Problems to be Solved by the Invention) However, at the grounds and courses such as athletic fields, stadiums, and golf courses in cold winter regions, a large amount of snowfall and snowfall cannot be escaped. In addition, these grounds and courses cannot be used optimally throughout the year unless the costly snow removal or snowmelt problems are solved, and therefore playgrounds and sports in snowy areas The place is completely unusable during winter,
Golf courses in mountainous hills have to be completely closed until early spring when the snow disappears.

The present invention has been developed to solve the above-mentioned problems. The purpose of the invention is to use a perforated pipe for drainage buried in the ground of a ground or a golf course, and to use the pipe very well. An object of the present invention is to establish an all-weather maintenance method in which the above-mentioned athletic field, stadium, golf course, and the like can be always used in an optimum environment all year round with simple equipment.

[Configuration of the invention]

(Means for Solving the Problems) The all-weather maintenance method for an athletic field or the like using a composite buried pipe according to the present invention includes an existing perforated pipe and a new non-perforated pipe at a position lowered by a predetermined depth from the next surface. The combination is buried in a plane direction in an evenly distributed state, and heat exchange is performed by selectively circulating water and air at an appropriate temperature in each of the pipes according to conditions such as weather.

(Example) Hereinafter, an example of a typical embodiment of the method of the present invention will be described in detail with reference to the drawings. The drawing shows an example in which the present invention is applied to the ground of a school playground in a snowy area in the back of Japan. It is about 30 to 60 from the ground surface 1 of the ground G.
a position lowered about cm, Yes in parallel buried in about 50~100cm intervals already plane direction diameter of about 150~200mm drain for perforated pipe P ₁ of the peripheral wall 2 of the perforated pipe P ₁ is , Diameter about
Small holes 3 10~15mm is bored a number, the distal end of the perforated pipe P ₁ is connected to the drainage through the water collecting pipe (not shown).

In the case of the present embodiment, the newly installed non-perforated pipe P ₂ is one diameter smaller than the existing perforated pipe P ₁ , and uses a pipe body in which the spacing piece 5 is protruded in the radial direction on the outer surface of the peripheral wall 4. This is the second
As shown in the drawing, a double-structured pipe inserted into the center of the existing perforated pipe P ₁ is a basic composite buried pipe P, and the existing perforated pipe P ₁ on the outside and the newly installed pipe P on the inside. Non-porous pipe
Tube end of the P ₂ are perforated pipe P ₁ of the composite buried pipe P at which the phase adjacent
Connecting tubes to each other and non-perforated pipe P ₂ between the U-shaped or U-shaped
P ₃ , P ₄ meanderingly connected, of which the pipe ends of the two pipes P ₁ , P _{2 at} the forefront pass through appropriate supply pipes, and switch the flow dividing valve, air supply, and water supply. It is connected to the blower 6 and the water supply pump 7 via a valve or the like, and the pipe ends of both pipes P ₁ and P _{2 at} the rear end are connected to drains via appropriate drain pipes.

Further, FIG. 3 to FIG. 6 is merely indicate typological other embodiments the composite buried pipe P to be applied to the present invention, imperforate pipe P ₂ of the newly opened, as Figure 3 illustrated or inserting the ones substantially triangular or square inside the perforated pipe P _1, a character type or human-shaped partition wall is formed integrally in the interior of the perforated pipe P ₁ as of FIG. 4 and FIG. 5 may be obtained by partitioning the internal space into two or more chambers, in some cases, perforated pipes of the existing P as in the sixth diagram separates the perforated pipe P ₂ of new ₁
May be buried in parallel.

The all-weather maintenance method for a sports ground or the like according to the present invention includes, for example, installing a pipe as shown in each of the above-described embodiments under the ground G and changing the existing ground G according to seasonal and weather fluctuations and other conditions of the ground G. always servicing the optimal state through perforated pipes P ₁ and 1 year use conditions on the ground G by which the imperforate pipe P ₂ optimum air and water newly been selectively flow heat exchange .

In other words, when the rainfall is relatively low during normal rainfall or when it is not necessary to use the ground immediately after the rain has stopped, the moisture that has soaked into the ground can be used without any special measures. through the perforated pipe P ₁ and flows out to the drain ditch. However, it can often precipitation, after the rain having stopped, immediately if you want to use the ground G, if Okurikome the air to the perforated pipe P _1, it is possible to promote the drainage of the tube, further perforated pipe and supplies the warm air to P _1, the interior of the imperforate pipe simultaneously
If flowing hot water or the like P _2, it is possible to rapidly evaporate the water content by increasing the underground temperature.

In addition, when the sunny day continues in the summer and the ground G dries dry, and when the dust rises to the ground G or when the temperature of the ground becomes abnormally high due to solar heat, cool water is circulated through the non-porous pipe P ₂ inside. lowering the underground temperature, in some cases, by supplying cold water to the outside of the perforated pipe P _1, by means of penetration into the ground from the small hole 3 of the pipe P ₁ peripheral wall, giving moisture to the ground At the same time, the temperature in the ground can be reduced.

On the other hand, in the ground G in winter cold regions, when the time or snowfall there is snow is expected, is passed through a relatively water or river water having a high temperature sewer, well water or the like to the non-perforated pipe P ₂ internal , while supplying a high sound air temperature in the perforated pipe P ₁ of the outer if necessary, melted snow by raising the ground temperature, no the snow ground G
Can be secured.

〔The invention's effect〕

As described above, if the all-weather preparation method using the composite buried pipe of the present invention is applied to a ground such as an athletic field and a stadium, or a course of a golf course, the existing perforated pipe buried underground is skillfully used. A very simple facility combining this with a newly installed non-perforated pipe has an excellent effect that the above-mentioned athletic field, stadium, golf course and the like can always be used in an optimum environment all year round.
