である。[Detailed Description of the Invention] (Field of Industrial Application) The present invention provides a construction method for constructed soil that has water permeability as constructed soil, does not freeze up, has compressive strength and bending strength, and is suitable for various uses. This invention relates to the invention.
（従来の技術及びその問題点）
構築土壌の構築方法としては、経済的なソイル
セメント工法が一般的である。(Prior art and its problems) As a method for constructing construction soil, the economical soil cement method is generally used.

ある。 This soil-cement method has a variety of applications, including rigid and deflecting roads, streets, lower and upper bases for airports, surface treatment of slopes subject to periodic and continuous water inundation and wave action, etc. The main products are cores for earth dams and linings for water storage areas.

機械的に締固め養生して圧縮強度及び曲げ強度を
得ることのみを主眼としていた。 The conventional soil cement method has been applied to the above-mentioned sites, but until now it has been difficult to select the soil to be used.
By using extremely large amounts of cement and tamping the soil, we adjust the water content to the optimum soil moisture content.
The main focus was on mechanically compacting and curing to obtain compressive strength and bending strength.
その為、当然ソイルセメント工法によつて得ら
れる構築土壌は非透水性であり、又非透水性でな
ければならないような現場に適用されているの
で、透水性があるソイルセメント工法など今まで
考えられたことはなかつた。 Therefore, the construction soil obtained by the soil cement method is naturally non-permeable, and since it is applied to sites where it must be impermeable, the soil cement method, which is permeable, has not been considered until now. I have never been disappointed.
一方、各種の運動競技場のスポーツサーフエー

されるということで問題となつている。 On the other hand, at various sports stadiums such as sports surf aces, sidewalks, jogging courses, etc., the softening of the ground surface due to rainwater has become a problem, limiting the period and time of use.
又、最近人工芝生あるいは人工芝生に乾燥砂を
充填したものを用いて造成する運動競技場の下層

と色々試みてきた。 Therefore, the present inventor has made various attempts to apply the soil cement construction method to the above-mentioned sports surf ace, the lower roadbed of artificial grass, sidewalks, jogging courses, etc.
ところがソイルセメント工法は、上記の用途に

とから透水性に極めて乏しいこと、次に氷点下に
なるような地域にあつては凍上するということ、
さらに寒さによつて土壌表面が破壊するというこ
とであつた。 However, it has been found that the soil cement method has a fatal drawback when used for the above-mentioned purposes. Since it is originally impermeable, it has extremely poor permeability, and secondly, in areas where the temperature drops below freezing, it will freeze up.
Furthermore, the soil surface was destroyed by the cold.
ソイルセメントの特性は、透水性を上げようと
すると、圧縮強度が落ち、圧縮強度を上げようと
すると透水性が落ちるという相反する関係があ

題である。 The properties of soil cement have a contradictory relationship: if you try to increase water permeability, the compressive strength will decrease, and if you try to increase the compressive strength, the water permeability will decrease, so it is a very difficult problem to solve the above drawbacks. .

般、研究、実験を通じて新知見を得、この新知見
に基いた本発明を完成するに至つた。 The present inventor is an engineer in the field of civil engineering and sports facilities, and in order to open up the application of soil cement to sports surf ace etc., it is necessary to overcome the various drawbacks of soil cement as described above.
I am also well aware that this is an extremely difficult skill. However, the low cost of soil constructed with soil cement is a major attraction above all else, and the present inventors dared to take on the above-mentioned difficulties and have been conducting research for many years. Through research and experiments, we have now obtained new knowledge and completed the present invention based on this new knowledge.
（問題点を解決する為の手段） 本発明の構成の詳細を以下に説明する。(Means for solving problems) The details of the configuration of the present invention will be explained below.
国際法土質学会の座標による土性は、LSが砂
質砂土、SLが砂壌土、Ｌが壌土、CLが植壌土と
されているが、土性がLS、SL、Ｌ、CLの順位で
105μ以下の土粒子は多くなる。 According to the coordinates of the International Society of Soil Quality, LS is sandy soil, SL is sandy loam, L is loam, and CL is planted soil.
The number of soil particles smaller than 105μ increases.
本発明の施工方法において使用する土壌は、国
際法土質学会の座標による土性がSL〜LSの範囲
の土壌である。 The soil used in the construction method of the present invention has a soil texture in the range of SL to LS according to the coordinates of the International Society of Soil Science and Technology.
この発明の土壌は、水硬性材料と混合し易く締
固めすると圧縮強度が上り易い性質をもつてい
る。 The soil of the present invention has the property of being easily mixed with hydraulic materials and having a high compressive strength when compacted.
しかし使用土が105μ以下の土粒子が５％以上
も含まれる土壌である場合には、前処理と称し、
土壌と水硬性材料とを混合して凝結させ、土性を
SL〜LSの範囲の土壌に粒径調整して使用する。 However, if the soil used contains 5% or more of soil particles of 105μ or less, it is called pre-treatment.
Mix soil and hydraulic material and solidify it to improve the soil texture.
Adjust the particle size and use it for soil in the SL to LS range.
この場合の一例を説明すると、１m3の土性が
CL〜Ｌの土壌の含水比を15％〜40％の間にし、
セメント30〜50Kgと混合して一昼夜放置しておく
と、土性がSL〜LSの範囲付近の土壌に粒径調整
できる。 To explain an example of this case, the soil texture of 1m3 is
The moisture content of soil from CL to L is between 15% and 40%,
By mixing it with 30 to 50 kg of cement and leaving it for a day or night, you can adjust the particle size to a soil with soil texture in the SL to LS range.
尚、本発明でいう水硬性材料とはセメントの
他、石コウ、石灰等の水で硬化する材料をいう。 The term "hydraulic material" as used in the present invention refers to materials that harden with water, such as gypsum and lime, in addition to cement.
（実施例）
土性がSL〜LSの範囲にある土壌の突固め最適
土壌含水比は、LS側で約６〜15％、SL側で約15
〜25％である。(Example) The optimum soil water content ratio for compacting soil whose soil texture is in the range of SL to LS is approximately 6 to 15% on the LS side and approximately 15% on the SL side.
~25%.
土壌の突固め最適土壌含水比17％の土壌１m3に
対し、100Kgのセメントを混合し、土壌含水比が

ローラーで４〜５回転圧をかけた場合、その透水
係数は４×10-4cm／secで圧縮強度は17Kg／cm2で
あつた。 Soil compaction: 1 m3 of soil with an optimum soil moisture content of 17% is mixed with 100 kg of cement, and the soil moisture content is 1.28 times the optimum soil moisture content for soil compaction (21.7).
4t after watering and adjusting and stirring to a soil moisture content of %
When pressure was applied 4 to 5 times with a roller, the water permeability coefficient was 4 x 10 -4 cm/sec and the compressive strength was 17 Kg/cm 2 .
尚、土壌含水比を調整する為に散水するのは水
のみでよいが、合成樹脂エマルジヨンを１m3の土
に10〜20Kg加えると圧縮強度はより増す。この点
で重要なことは、水硬性材料と土壌を土壌突固め
最適土壌含水比で締固めると、圧縮強度はでない
が、透水性があるということであり、土壌の突固
め最適土壌含水比以下で締固めると、透水性は良
好であるが、圧縮強度が著しく落ちるということ
である。 In addition, only water can be sprinkled to adjust the soil water content ratio, but if 10 to 20 kg of synthetic resin emulsion is added to 1 m 3 of soil, the compressive strength will further increase. What is important in this regard is that when hydraulic materials and soil are compacted at the optimum soil moisture content for soil compaction, they do not have compressive strength but have water permeability; When compacted, water permeability is good, but compressive strength is significantly reduced.
又、土壌の突固め最適土壌含水比の1.2倍以下
の土壌含水比で締め固めると透水性は良好である
が圧縮強度は必要とされる強度がでず、一方土壌
の突固め最適土壌含水比の1.5倍以上の土壌含水
比で締固めると、透水性も圧縮強度も共に落ち
る。 Also, if the soil is compacted at a soil water content ratio that is 1.2 times or less than the optimum soil water content ratio, the water permeability will be good, but the compressive strength will not be as high as required; When compacted with a soil moisture content of 1.5 times or more, both water permeability and compressive strength decrease.
従つて土壌の突固め最適土壌含水比の1.2〜1.5
倍の土壌含水比で締固めると、透水性を良好に保
つたままで、圧縮強度を満足する強度にすること
が可能である。 Therefore soil compaction with optimum soil water content ratio of 1.2 to 1.5
By compacting the soil at twice the water content, it is possible to achieve a satisfactory compressive strength while maintaining good water permeability.
次に、土壌表面の曲げ強度を上げ、寒さによる

When watering at a rate of 1 to 2/m 2 during sheet curing for ~5 days, the bending strength of the soil surface was 3.4 kg/cm 2 compared to 2.7 kg/cm 2 in the plot without watering at 28 days old.
It was possible to significantly increase the intensity by cm 2 .

水が発生しない為、効果がより顕著である。 In addition, if water is sprinkled within 1 to 5 days after completion of construction, the soil and cement may not have solidified strongly, so if you sprinkle a 0.05 to 0.03% aqueous solution of polyethylene oxide, which is a polymeric soil aggregation agent, it will cause muddy water. The effect is more pronounced because no
次に凍上防止方法について説明すると、一般的
に圧縮強度が、20Kg／cm2以上であれば土は凍上抑
制効果があるといわれている。 Next, to explain how to prevent frost heaving, it is generally said that if the compressive strength of the soil is 20 kg/cm 2 or more, the soil has an effect of inhibiting frost heaving.

You only need to sprinkle water at a rate of about 28.0 kg/cm 2 after 28 days, and the water permeability will not change .
can be significantly increased.
従つて透水性があり、かつ凍上せず、寒さによ

ローラーで転圧する。 Next, I will explain the on-site construction method for the sub-base course for tennis clay courts and sports stadiums made of artificial grass.First, it is decided whether the site will be filled with a bed or a bed excavated, and both the bed heap and the bed excavation are carried out by approximately 30 cm.
To explain about the site where the floor is piled up, there is a

調整する。 Next, either bring good quality soil with a soil quality in the range of SL to LS to the site, or if local soil is used, investigate whether it contains 5% or more of soil particles with a size of 105μ or less, and check if soil contains 5% or more. If so, adjust the particle size with cement.

Sprinkle water with 15 kg of ethylene vinegar beer emulsion and stir the soil again with a tractor. After this, temporary rolling is done two to three times with a 4t roller, then unevenness is corrected, and then the final rolling is completed.
