本発明は古い地層の山地に河川水、汚水等を土壌で浄化
しながら貯溜し、濯慨用水、水産用水、上水等に再利用
するための方法に関するものである。[Detailed Description of the Invention] The present invention relates to a method for storing river water, sewage, etc. in a mountainous area with old strata while purifying it with soil, and reusing it as irrigation water, fisheries water, clean water, etc. .
扇状地など平地の地下水量に河川水、雨水、汚水等を地
表面の土壌で浄化しながら浸透させ、地下水量を人工的
に増加させ、それを必要な時に揚水して利用することは
従来から行なわれているが、この方法は平地に限定され
、山地の多い我国では実用的でない。It has been conventional practice to artificially increase the amount of groundwater by allowing river water, rainwater, sewage, etc. to infiltrate the groundwater in flat areas such as alluvial fans while being purified by the soil on the ground's surface, and then pump and use the water when needed. However, this method is limited to flat areas and is not practical in Japan, which has many mountains.
それに実際に水資源が不足する所は意外に山地やそれに
近い所に多いのが現実である。Moreover, the reality is that surprisingly many places that lack water resources are in or near mountains.
ところで、一般に山地には第１図ＡＭ示すような新しい
地層から成るものと、第１図Ｂに示す様な古い地層から
戒るものがある。By the way, in general, there are mountain areas that are made up of new strata, as shown in Figure 1 AM, and those that are made up of old strata, as shown in Figure 1 B.
前者は第１図Ａから明らかなように、母岩１の表面に通
常厚さが５０ｃｒｎ程度の表面土壌２が堆積したもので
、この様な地層では山に降った雨水は表面土壌２０表面
及びその中を矢印ａの如く流下し、母岩１内には浸透し
ない。As is clear from Figure 1A, in the former case, surface soil 2 with a thickness of about 50 crn is deposited on the surface of host rock 1, and in such a stratum, rainwater that falls on the mountain is deposited on the surface soil 20 and on the surface of the surface soil 20. It flows down through it as shown by arrow a and does not penetrate into the host rock 1.
これに対して、後者の古い地層は第１図Ｂから明らかな
様に山地を形成する母岩の殆んどは風化が進行して、い
わゆる風化母岩３となっているため、雨水はこの風化母
岩３中にも浸透し、保水されて一時的に貯溜され、矢印
すの如く少しずつ流出されることになる。On the other hand, in the latter older strata, as is clear from Figure 1B, most of the host rocks that form the mountains have progressed to weathering and become what is called weathered host rock 3, so rainwater flows into this layer. It also penetrates into the weathered host rock 3, retains water and is temporarily stored, and is gradually drained out as shown by the arrow.
本発明は山地に於ける常習水不足に鑑み、上記風化母岩
から成る山地の特質に着目してなされたもので、その目
的とするところは、山地を流れる渓流や山間部に発生す
る汚水等を極めて簡単かつ安価な方法にて浄化貯溜せし
め、水資源不足対策に応えんとするものである。The present invention was made in view of the chronic water shortage in mountainous regions, focusing on the characteristics of mountainous regions made of weathered host rocks. The aim is to purify and store water using an extremely simple and inexpensive method, in response to water resource shortages.
以下、本発明方法の一実施例を図面を参照しながら説明
する。An embodiment of the method of the present invention will be described below with reference to the drawings.
第２図に於て、母岩１、表面土壌２及び風化母岩３は上
記第１図と同様である。In FIG. 2, host rock 1, surface soil 2, and weathered host rock 3 are the same as in FIG. 1 above.
４は渓流であって揚水ポンプ５、バイブロにより山頂附
近に揚水する。4 is a mountain stream, and water is pumped up near the mountain top by a water pump 5 and a vibro.
バイブロの上端部にはスプリンクラ７や地下トレンチ溝
８を配して、表面土壌２中に潅水する。A sprinkler 7 and an underground trench groove 8 are arranged at the upper end of the vibro to irrigate the surface soil 2.
山頂部に潅水された渓流等の河川水は風化母岩３中に浸
透し、貯溜せしめられる。River water such as a mountain stream irrigating the mountain top permeates into the weathered host rock 3 and is stored.
また、汚水を直接或いは渓流中に混入して揚水し潅水す
れば風化母岩３中を浸透する際浄化され、同時に貯溜さ
れる。Furthermore, if wastewater is pumped directly or mixed into a mountain stream for irrigation, it will be purified as it permeates through the weathered host rock 3 and will be stored at the same time.
貯溜された水は長時間かげて浸出Ｃされ、再利用される
。The stored water is leached for a long time and reused.
本発明は以上の様に、風化母岩を利用しているので、そ
の地層は数百メートルにも達し、地層が深いと月単位で
貯溜が可能であり、梅雨期の雨水を夏の渇水期に利用し
たり、雪融期の水を水稲の濯概期に利用する等の水量調
節が可能となる。As described above, the present invention utilizes weathered host rock, so the strata are several hundred meters long, and if the strata are deep, it can be stored for months, and rainwater during the rainy season can be stored during the summer dry season. This makes it possible to adjust the amount of water, such as by using water during the snow melting season for the rice rinsing season.
特に我国での降雨条件は渇水期と豊水期とは２〜３ケ月
の差があり本発明方式が最適である。In particular, the rainfall conditions in Japan are such that there is a difference of 2 to 3 months between the dry season and the high water season, making the method of the present invention optimal.
また河川を堰止めてダムを作って貯溜する方式よりも、
建設費や地域補償を必要とせず、豊水時の水力発電によ
る電力を活用して揚水すれば非常に安価に実施し得る利
点がある。Also, rather than blocking rivers and building dams to store water,
It has the advantage that it does not require construction costs or local compensation, and can be implemented at a very low cost if the water is pumped using electricity generated from hydroelectric power generation during times of high water.
上記風化母岩層は一般に平地の礫層や堆積土壌層に比較
して浄化力に富み、更に山地の植物や土壌動物等も汚水
浄化に参加させ得る利点もある。The above-mentioned weathered host rock layer generally has a richer purifying power than the gravel layer or sedimentary soil layer on the plains, and also has the advantage that plants and soil animals in the mountains can participate in wastewater purification.
