The present invention is performed at a place where there is waste, specifically, at a place where the waste is illegally dumped, a waste disposal site, a building demolition site, or the like. In the specification of the present application, “on-site with waste” refers to a place where there is waste as described above or the vicinity thereof. These places may be places where there is no water supply and it is difficult to obtain water necessary for hardening the hydraulic material. The method of the present invention is suitable for the construction of structures that do not require much strength, but can also be applied to the construction of civil engineering structures that are allowed to exhibit strength over a long period of time.
本発明の方法は、水硬性材料の硬化が現地でなされるので、土木構造物を施工するべき現場またはその周辺で実施可能である。従って、例えばコンクリートブロックのようなすでに硬化した部材を現地に運搬し、組み立てる必要はない。本発明の方法で使用される廃棄物はまた、現地での調達が可能である。 The method of the present invention can be performed at or near the site where a civil engineering structure is to be constructed because the hydraulic material is cured on site. Thus, it is not necessary to transport and assemble already hardened components such as concrete blocks to the site. The waste used in the method of the invention can also be procured locally.
本発明の１つの実施形態において、水硬性材料の硬化は、水硬性材料および骨材として使用される廃棄物を混ぜたものを充填した袋体を設置し、水分が袋体内に侵入することによって行われる。例えば、水硬性材料の硬化は、土壌および大気中の水分または雨水が袋体内に侵入することによって行われる。 In one embodiment of the present invention, the hydraulic material is cured by installing a bag filled with a mixture of hydraulic material and waste used as an aggregate, and moisture entering the bag.

本発明の１つの実施形態において、水硬性材料の硬化のために水が添加されてもよい。例えば、水硬性材料の硬化のために、散水により水分を追加しても良い。また、水分を含む土壌を、水硬性材料および骨材と混合しても良い。水硬性材料の硬化は、袋体を積み重ねる毎に行っても良いし、全て積み重ねた後に行っても良い。 In one embodiment of the invention, water may be added for curing the hydraulic material. For example, moisture may be added by watering in order to cure the hydraulic material. In addition, soil containing moisture may be mixed with hydraulic material and aggregate. The hydraulic material may be cured every time the bags are stacked or after all the bags are stacked.
本発明の土木構造物の施工方法は、未硬化の水硬性材料を含む袋体を、お互いに接触するように、並べて配置することを特徴とする。並べて配置するのは、横に並べても良いし縦に積み重ねても良い。袋体中の水硬性物質が硬化した後に、新たな未硬化の水硬性材料を含む袋体をさらに積み重ねてもよい。未硬化の水硬性材料を含む袋体を積み重ねる工程は、必要に応じて繰り返され得る。 The construction method for a civil engineering structure according to the present invention is characterized in that bags containing uncured hydraulic materials are arranged side by side so as to contact each other. They can be arranged side by side or stacked vertically. After the hydraulic substance in the bag is hardened, the bag containing a new uncured hydraulic material may be further stacked. The process of stacking bags containing uncured hydraulic material can be repeated as needed.
本発明の土木構造物の施工方法は、未硬化の状態の水硬性材料と廃棄物と必要に応じて水との混合物を袋体に充填して設置することを特徴とする。 The construction method of the civil engineering structure of the present invention is characterized in that a bag is filled with a mixture of an uncured hydraulic material, waste, and water as required.
本発明において使用される水硬性材料としては、セメントが挙げられるがこれに限定されない。このセメントはドライであるので、セメントの硬化には、土壌および空気中の水分並びに雨水が使用される。または、必要に応じて、水が添加される。 The hydraulic material used in the present invention includes, but is not limited to, cement. Since this cement is dry, moisture in the soil and air and rainwater are used to harden the cement. Alternatively, water is added as necessary.
本発明において、骨材として廃棄物が使用される。本発明において、骨材として、廃プラスチック、廃木材、がれき類、紙くず、繊維くず、またはこれらの混合物等の産業廃棄物も同様に使用されるが、これらに限定されない。本発明において使用される廃棄物は、好ましくは、破砕機によって破砕され、所定のサイズ以下のものが使用される。所定のサイズを超える場合には、さらに破砕して小さくした後、骨材として使用される。 In the present invention, waste is used as the aggregate. In the present invention, industrial waste such as waste plastic, waste wood, debris, paper waste, fiber waste, or a mixture thereof is also used as the aggregate, but is not limited thereto. The waste used in the present invention is preferably crushed by a crusher, and those having a predetermined size or less are used. When it exceeds a predetermined size, it is further crushed and reduced in size, and then used as an aggregate.
本発明において、袋体中で硬化した水硬性材料と廃棄物の混合物は、好ましくは、セメントと廃棄物の混合物であり、袋体中に充填される廃棄物の組成を変えることによって、コンクリートの比重を調節することが可能である。 In the present invention, the hydraulic material and waste mixture hardened in the bag is preferably a cement and waste mixture, and the concrete composition is changed by changing the composition of the waste filled in the bag. It is possible to adjust the specific gravity.
本発明の土木構造物の施工方法は、変形自在な袋体を使用することを特徴とする。本発明の袋体は、変形自在であり、すなわち、柔軟性を有する。また、本発明の袋体は、型枠自体のように硬すぎるものでもない。本発明において使用される変形自在な袋体としては、フレコンバッグが挙げられるがこれに限定されない。このフレコンバックの形状は、１ｍ×１ｍ×１ｍの立方体形状を始めとして、約０．０５ｍ３〜約２．０ｍ３の丸形、角形、ブロック形、平板形等の形状である（図６および７を参照のこと）。フレコンバックの容量としては、例えば、０．１ｍ３、０．５ｍ３、０．８ｍ３、１．５ｍ３、または２．０ｍ３が市販されているが、これらに限定されない。好ましい一辺の大きさとしては、約０．０５ｍ〜約２ｍである。本発明において使用される変形自在な袋体は、好ましくは、小さい孔を有する。必要に応じて水を添加した場合には、小さい孔から水硬性物質が浸み出し、袋体同士の接着性を高め、袋体間の空間を減少させることができる。本発明において使用される変形自在な袋体は、好ましくは、クレーンによって吊ることを可能にするように、上部にひもがついている（図２を参照のこと）。 The construction method of the civil engineering structure of the present invention is characterized by using a deformable bag. The bag of the present invention is deformable, that is, has flexibility. Further, the bag of the present invention is not too hard like the mold itself. The deformable bag used in the present invention includes, but is not limited to, a flexible container bag. The shape of the FIBC is including the cubic shape of 1 m × 1 m × 1 m, round about 0.05 m 3 ~ about 2.0 m 3, triangular, block-shaped, in the shape of a flat plate shape such as a (FIG. 6 and 7).

A preferable size of one side is about 0.05 m to about 2 m. The deformable bag used in the present invention preferably has small holes. When water is added as necessary, the hydraulic substance oozes out from the small holes, thereby improving the adhesion between the bags and reducing the space between the bags. The deformable bag used in the present invention is preferably strapped on the top so that it can be hung by a crane (see FIG. 2).
