本発明は、地表面の凍結及び積雪防止方法に関し、特に
寒冷地における地表面の凍結及び積雪防止方法に関する
。DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) The present invention relates to a method for preventing ground surface freezing and snow accumulation, and particularly to a method for preventing ground surface freezing and snow accumulation in cold regions.
（従来の技術）
寒冷地における地表面の凍結は植物の育成を不可能とす

場のグリーンのように、クツション性が必要な場所では
、地表面の凍結により土壌の弾性が失われるのみならず
芝の生育も著しく劣下するので遊戯性を半減させること
になる。(Prior Art) Freezing of the ground surface in cold regions is an extremely important problem as it makes it impossible to grow plants. Furthermore, in areas where cushioning properties are required, such as golf course greens, freezing of the ground surface not only causes the soil to lose its elasticity, but also significantly reduces the growth of grass, halving the playability. .
しかるに、従来から水道管その他の流体配管系の凍結防

）及び液化天然ガスなどの低温液体を貯蔵する地下タン
クの周辺の土壌に生じる凍結を電熱加熱により防止する
というような技術が散見されるに過ぎない。However, although many technologies have been developed to prevent freezing of water pipes and other fluid piping systems, there has been little development of antifreeze technology related to the ground surface. As a method of preventing freezing when supplied, there is a method of preventing freezing in the aqua regia pressure detection impulse pipe of a flow meter that measures the flow rate of tap water (Japanese Patent Application Laid-open No. 58-58414) and low-temperature liquids such as liquefied natural gas. There are only a few technologies that can be found here and there, such as using electric heating to prevent soil from freezing around underground tanks that store fuel.
しかしながら、電熱加熱等の直接的加熱手段は、地表全
面の凍結防止を一様に行うためには不適当である。However, direct heating means such as electric heating are not suitable for uniformly preventing freezing over the entire surface of the earth.
又、豪雪地帯はもとより、頻繁に積雪する地域において
は除雪して歩道を確保することが容易ではない。幹線道

るを得ない。Furthermore, in areas where snow frequently accumulates, as well as areas with heavy snowfall, it is not easy to remove snow and secure sidewalks. On main roads, water is sprinkled in the center of the road to melt snow, but this method is not only expensive, but it also makes it impossible to secure valuable water, resulting in water shortages. The locations where it can actually be used must be extremely limited.
従って、−船道路においては降雪により著しく危険性が
増大することはもとより、個人の家及びその周辺におい
ては、個々の家で除雪しなければ安全を確保することが
できないのが現実である。Therefore, not only does snowfall significantly increase the danger on shipping roads, but the reality is that safety cannot be ensured in and around private homes unless snow is removed at each individual home.
しかしながら、核家族化や老齢化の進行する中で、かか
る重労働の提供は困難となりつつあり、除雪が不十分と
なるために危険性が増大しつつあると言っても過言では
ない。However, as the number of nuclear families increases and the population ages, it is becoming difficult to provide such hard labor, and it is no exaggeration to say that the danger is increasing due to insufficient snow removal.

段も当然に含まれる。To adjust the temperature of the air to 0℃ or above, a heat insulating tank or septic tank buried underground is used as a means of regulating the air, but other methods include adding a heater to a blower to directly generate hot air, using a boiler, or using a boiler in a factory. Of course, this also includes means to utilize waste heat, etc. generated by such processes.
以下、本発明を実施例に基づいて詳しく説明する。Hereinafter, the present invention will be explained in detail based on examples.
第１図において、符号（１）は０℃以上の空気を地表面
の土壌内に放出するための排気管である。In FIG. 1, reference numeral (1) is an exhaust pipe for discharging air at a temperature of 0° C. or higher into the soil on the ground surface.
この排気管から放出された比重の軽い温かい空気は地表
面に向って自然に流れるから、排気孔は排気管の上側の
みならず、任意の箇所に設けることができる。Since warm air with a light specific gravity discharged from the exhaust pipe naturally flows toward the ground surface, the exhaust hole can be provided not only at the top of the exhaust pipe but also at any desired location.
符号（２）は、空気をＯ″Ｃ０以上節する環境を確保す
るための保温槽である。この保温槽内の空気は、地中の
温度が一部を通してほぼ一定であることから、冬場でも
外気より高い温度に保つことができる。Code (2) is a heat insulating tank to ensure an environment where the air is kept at or above O''C0.The temperature of the air in this heat insulating tank is almost constant throughout the area, so even in winter, the air inside this heat insulating tank is warm. It can maintain a higher temperature than the outside air.
保温槽としては既設の浄化槽を用いることもできる。An existing septic tank can also be used as the heat retention tank.
符号（３）は、保温槽内の空気を排気管に送風するため
の送風手段である。送風手段としては公知のものの中か
ら適宜選択して採用することができる。本実施例の場合
は送風機としている。Reference numeral (3) denotes a blowing means for blowing the air inside the heat-retaining tank to the exhaust pipe. The blowing means can be appropriately selected from known ones. In this embodiment, a blower is used.
符号（４）は、保温槽内に外気を取り入れるための吸気
口である。吸気口は保温槽の蓋又は蓋の一部に取り外し
自在の格子を設ける等、平面的に設けることもできる。Reference numeral (4) is an intake port for taking outside air into the heat-retaining tank. The intake port can also be provided in a flat manner, such as by providing a removable grid on the lid or a part of the lid of the heat-retaining tank.
又、吸気口を保温槽から離れた所に設け、地下２〜３ｍ
に埋設した導管を通して外気を温めながら保温槽に取り
入れることもできる。In addition, the air inlet should be placed away from the heat retention tank, 2 to 3 meters underground.
It is also possible to heat the outside air and introduce it into the heat storage tank through a pipe buried in the tank.
外気をＯ″Ｃ０以上熱することのできる加熱手段（５）
は、外気取り入れ口、保温槽内、送風手段等の何れの箇
所に設置しても良い。Heating means (5) capable of heating outside air at O″C0 or more
may be installed at any location such as the outside air intake, inside the heat insulating tank, or at the ventilation means.
保温槽として浄化槽を使用した場合には、汚水の浄化に
際して発熱するので他の加熱手段を用いなくても良いが
、併用しても良いことは当然である。When a septic tank is used as a heat-retaining tank, since heat is generated during purification of wastewater, other heating means may not be used, but it is natural that they may be used in combination.
（作 用）
