Description
本考案は土壌改質材に関し、特に窯業系製品の製造に伴う産業副産物を利用した環境負荷の少ない土壌改質材に関する。 The present invention relates to a soil reforming material, and in particular to a soil reforming material that uses industrial by-products from the manufacture of ceramic products and has a low environmental impact.
建設工事の施工に伴って発生する土砂や汚泥は、一般に建設発生土と呼ばれ、建設発生土の内、水分含有量が多く泥濘の状態になっているものは、特に建設汚泥と呼ばれる。
国土交通省によれば、建設汚泥とは、「標準仕様ダンプトラックに山積みできず、その上を人が歩けないような流動性を呈する状態のもの」を指し、コーン指数２００ｋＮ／ｍ２以下もしくは一軸圧縮強度が５０ｋＮ／ｍ２以下の建設発生土と定義される。
建設汚泥は、廃棄物処理法が定義する廃棄物となるため、再利用が認められず処分に多額の費用がかかる。
また、建設汚泥は現場に平置きすることができず、保管槽内に貯めておかなければ流出してしまうため、保管に広いスペースを要する上、ダンプトラック等で搬送する時も、荷台を防水養生しないと流出してしまうため、取り扱いが難しい。
Earth and sand and sludge generated during construction work are generally referred to as construction generated soil, and among construction generated soil, soil that has a high moisture content and is in a muddy state is particularly referred to as construction sludge.
According to the Ministry of Land, Infrastructure, Transport and Tourism, construction sludge refers to ``sludge that exhibits such fluidity that it cannot be piled up in a standard dump truck or that a person cannot walk on it,'' and has a cone index of 200 kN/ m2 or less, or It is defined as construction generated soil with an unconfined compressive strength of 50kN/ m2 or less.
Construction sludge is considered waste as defined by the Waste Management and Public Cleansing Act, so it cannot be reused and disposal costs a large amount of money.
In addition, construction sludge cannot be laid flat on the site and will flow out unless it is stored in a storage tank, so it requires a large space for storage, and when transported by dump truck, etc., the loading platform is waterproof. If it is not cured, it will flow out, making it difficult to handle.
建設汚泥を改質する従来技術として、セメント系固化材を用いる方法がある。
詳細には、建設汚泥にセメント系固化材を添加して、セメントを汚泥中の水分と反応させ、汚泥の含有水分量を低減させると共に強度発現させることで、取り扱いを容易にする。
然るに、建設汚泥を完全に固化させるためには、３０％程度の添加量が必要となるため、使用量が膨大となる上、セメント系固化材で固めた汚泥は建設廃材になるため、処分費用が嵩む。
As a conventional technique for reforming construction sludge, there is a method using a cement-based solidifying agent.
Specifically, a cement-based solidifying agent is added to construction sludge to cause the cement to react with the water in the sludge, thereby reducing the amount of water contained in the sludge and increasing its strength, thereby making it easier to handle.
However, in order to completely solidify construction sludge, approximately 30% of the additive amount is required, which results in an enormous amount of use.In addition, the sludge solidified with cement-based solidification material becomes construction waste, so disposal costs are high. increases.
本考案の土壌改質材は、窯業系製品の製造工程で生ずる窯業系製品の粉体、及び／又は窯業系製品の製造工程で生ずる窯業系製品の端材を挽砕した粉体、を主体とし、粉体は複数の多孔性の焼結粒体からなり、袋体内に充填したことを特徴とする。 The soil reforming material of the present invention is mainly composed of powder of ceramic products produced in the manufacturing process of ceramic products and/or powder obtained by grinding offcuts of ceramic products produced in the manufacturing process of ceramic products. The powder is composed of a plurality of porous sintered particles and is characterized in that it is filled into a bag.
本考案の土壌改質材は、窯業系製品が、陶器、磁器、ガラス、セメント、石膏及び石灰の内少なくとも１種類を含んでいてもよい。 In the soil reforming material of the present invention, the ceramic product may include at least one of pottery, porcelain, glass, cement, gypsum, and lime.
本考案の土壌改質材は、粉体が、長石、珪石、石灰石、陶石、珪砂、粘土、珪藻土、及びアルミナの内少なくとも１種類を含んでいてもよい。 In the soil reforming material of the present invention, the powder may contain at least one of feldspar, silica, limestone, chinastone, silica sand, clay, diatomaceous earth, and alumina.
本考案の土壌改質材は、袋体が、重機にて吊り上げ可能な把手を備えるフレコンバッグであってもよい。 The soil reforming material of the present invention may be a flexible container bag in which the bag body is provided with a handle that can be lifted by heavy machinery.
本考案の土壌改質材は、窯業系製品の製造に伴う産業副産物を利用した１００％リサイクル製品であるため、環境負荷が少ない。
また、セメント系固化材と異なり、土壌を完全に硬化させないため、建設発生土として盛土や埋戻に再利用可能である。
さらに、本来費用をかけて処分していた産業副産物をリサイクルした製品であるため、マイナス原価である上、セメント系固化材のように産業廃棄物処理費用がかからない。
The soil reforming material of the present invention is a 100% recycled product that uses industrial by-products from the manufacture of ceramic products, so it has less environmental impact.
Also, unlike cement-based solidifying materials, it does not completely harden the soil, so it can be reused as construction soil for embankments and backfilling.
Furthermore, since it is a product made by recycling industrial by-products that would otherwise be disposed of at a high cost, it has a negative cost and does not require the cost of industrial waste disposal, unlike cement-based solidifying materials.
以下、図面を参照しながら本考案の土壌改質材について詳細に説明する。
なお、本考案において土壌の「改質」とは、少なくとも土壌の含有水分量の低減と強度発現を含む。
Hereinafter, the soil reforming material of the present invention will be described in detail with reference to the drawings.
Note that in the present invention, "improving" soil includes at least reducing the moisture content of soil and developing strength.

[Soil improvement material]
<1> Overall configuration (Figure 1)
The soil modification material 1 of the present invention is a modification material (agent) derived from ceramic product A.
Soil modification material 1 is mainly effective as a modification material for muddy soil B. However, it is applicable not only to mud B but to any soil that has room for improvement. Further, in this example, an example in which the mud B is construction sludge will be described, but the mud B is not limited to construction sludge.
The soil reforming material 1 is mainly composed of powder 10 generated during the manufacturing process of the ceramic product A.
In detail, the powder 10 produced in the manufacturing process of the ceramic product A and the powder 10 obtained by grinding the scraps of the ceramic product A are mainly used.
The powder 10 is filled into a bag 20 having an appropriate capacity for convenience of storage and transportation.
＜１．１＞窯業系製品
本考案において「窯業系製品」とは、無機化合物を高熱処理し焼き固めて製造した製品全般を意味する。
本例では、窯業系製品Ａが窯業系サイディングである例について説明する。
窯業系サイディングは、繊維質を混和したセメントを薄板状に加工した外壁材である。
窯業系サイディングは、低廉でデザインが豊富であり、耐候性と耐火性に優れ、かつ施工が容易であるため、国内の新築住宅に設けるサイディングでは最も多く採用されている。
窯業系サイディングの製造工程では、板状材料のロール成型、焼結、オートクレープ養生の後、既定のサイズに裁断し、断面を研磨する。この材料の裁断・研磨の際にダストとして多量の粉体１０が発生する。また、裁断時の端材を挽砕処理することによって多量の粉体１０が発生する。
これらの粉体１０を集塵機で回収し、袋体２０内に充填することで土壌改質材１を製造する。
なお、窯業系製品Ａは、窯業系サイディングに限らず、陶器、磁器、ガラス、セメント、石膏、石灰等、広義のセラミック製品全般を含む。
<1.1> Ceramic products In the present invention, "ceramic products" refers to all products manufactured by high heat treatment and baking of inorganic compounds.
In this example, an example will be described in which the ceramic product A is ceramic siding.
Ceramic siding is an exterior wall material made of cement mixed with fibers processed into thin sheets.
Ceramic siding is inexpensive, comes in a wide variety of designs, has excellent weather and fire resistance, and is easy to install, so it is the most commonly used siding for new homes in Japan.
In the manufacturing process for ceramic siding, plate-shaped materials are roll-formed, sintered, and autoclaved, then cut to a predetermined size and polished in cross section. When cutting and polishing this material, a large amount of powder 10 is generated as dust. Moreover, a large amount of powder 10 is generated by grinding the scraps during cutting.
These powders 10 are collected by a dust collector and filled into a bag 20 to produce the soil reforming material 1.
Note that the ceramic products A include not only ceramic siding but also ceramic products in a broad sense such as pottery, porcelain, glass, cement, plaster, and lime.
＜２＞粉体（図２）
粉体１０は、吸水性を備える粉末の集合体である。
粉体１０は、複数の焼結粒体１１からなる。
粉体１０の組成は、窯業系製品Ａの種類によって異なるが、少なくとも、長石、珪石、石灰石、陶石、珪砂、粘土、珪藻土、アルミナ等の無機物質のうち一種類、又はこれらの混合物を含む。
焼結粒体１１は、表面に多数の細孔１１ａを備える。すなわち、窯業系製品Ａは、原料の焼結プロセスにおいて多孔質となるため、これを挽砕処理して製造する焼結粒体１１も粒体レベルにおいて多孔質構造となる。
<2> Powder (Figure 2)
The powder 10 is an aggregate of powder having water absorption properties.
The powder 10 consists of a plurality of sintered granules 11.
The composition of the powder 10 varies depending on the type of ceramic product A, but it contains at least one type of inorganic substance such as feldspar, silica, limestone, pottery stone, silica sand, clay, diatomaceous earth, alumina, etc., or a mixture thereof. .
The sintered granules 11 have a large number of pores 11a on the surface. That is, since the ceramic product A becomes porous during the sintering process of the raw material, the sintered granules 11 produced by grinding this product also have a porous structure at the granule level.
＜３＞袋体
袋体２０は、粉体１０を充填するための容器である。
本例では袋体２０として、重機にて吊り上げ可能な把手２１を備えるフレコンバッグを採用する。
フレコンバッグは、ポリプロピレン（ＰＰ）等の合成樹脂製のフラットヤーンを編成してなるバッグである。
フレコンバッグは、折り畳み可能であるため嵩張らず、軽量、かつ安価であるため粉体１０を充填する袋体２０として好適である。また、粉体１０を取り出すために袋表面を破いて使用することもできる。
<3> Bag The bag 20 is a container for filling the powder 10.
In this example, a flexible container bag equipped with a handle 21 that can be lifted by heavy equipment is used as the bag body 20.
A flexible container bag is a bag made by knitting flat yarns made of synthetic resin such as polypropylene (PP).
The flexible container bag is suitable as the bag body 20 for filling the powder 10 because it is foldable and therefore not bulky, lightweight, and inexpensive. Alternatively, the bag surface can be torn to remove the powder 10.
＜４＞土壌改質材の使用方法（図３）
土壌改質材１によって、例えば以下の手順で泥土Ｂを改質する。
処理槽に泥土Ｂを投入する。
泥土Ｂ上に袋体２０内の粉体１０を投入する。粉体１０の添加量は、泥土Ｂの含水率によるが、概ね１～１５％程度である。
バックホウのバケットで、泥土Ｂと粉体１０を攪拌する。
泥土Ｂと粉体１０の混合によって、泥土Ｂ内の含有水分が焼結粒体１１の細孔１１ａ内に吸着され、泥土Ｂの含有水分量が低減すると共に、泥土Ｂの一軸圧縮強が向上する。
本考案の土壌改質材１は、攪拌混合後の養生が必要ないため、仮置き場を必要とせず即時搬出することができる。
土壌改質材１によって泥土Ｂを改質することで、搬送・保管等における泥土Ｂの取り扱いが容易になると共に、所定の品質基準（コーン指数２００ｋＮ／ｍ２超かつ一軸圧縮強度が５０ｋＮ／ｍ２超）を満たすことで、建設発生土として盛土や路床などに再利用することが可能となる。
<4> How to use soil reforming material (Figure 3)
Mud soil B is modified using the soil modification material 1, for example, in the following procedure.
Pour mud B into the treatment tank.
The powder 10 in the bag 20 is thrown onto the mud B. The amount of powder 10 added depends on the moisture content of mud B, but is approximately 1 to 15%.
Mud B and powder 10 are stirred with a backhoe bucket.
By mixing the mud B and the powder 10, the moisture contained in the mud B is adsorbed into the pores 11a of the sintered granules 11, the water content of the mud B is reduced, and the uniaxial compressive strength of the mud B is improved. do.
Since the soil reforming material 1 of the present invention does not require curing after stirring and mixing, it can be immediately transported without requiring a temporary storage area.
By modifying mud B with soil modification material 1, handling of mud B during transportation, storage, etc. becomes easier, and it also meets the prescribed quality standards (cone index exceeding 200 kN/m 2 and unconfined compressive strength of 50 kN/m 2 ), it becomes possible to reuse construction soil for embankments, roadbeds, etc.
