をカートリッジとして調整したものを納めて成るもの（
実開昭６２−１４８３５６号公報）等がある。Static crushing agents known so far either require adding water and kneading before use, or they are placed in a container through which water can easily permeate or infiltrate, and then immersed in a container that allows rock or concrete to be hydrated. Something to be inserted into the borehole (Japanese Patent Application Laid-open No. 1983
-74474 Publication), and furthermore, a cartridge containing a cartridge with the required amount of water adjusted in advance (
Utility Model Application Publication No. 62-148356), etc.

される。<Problems to be solved by the invention> The former requires skill when adjusting the water ratio on-site, and the proper water ratio is often not maintained, leading to problems such as insufficient power and gushing phenomena. It was easy to invite. On the other hand, although the latter does not cause such problems, housing the crushing agent and the water container in the same container raises concerns about problems when the water container is damaged, reliability of moisture permeability, and the like.
く問題点を解決するための手段〉
本発明者等は、上記の如き欠点のない静的破砕カプセル
を得べく鋭意工夫した結果、本発明をなすに至った。Means for Solving the Problems> The present inventors have made extensive efforts to obtain statically crushed capsules free from the above-mentioned drawbacks, and as a result, have achieved the present invention.
すなわち、本発明は、酸化カルシウムを主成分とする静
的破砕剤を、水又は水溶液が透過又は浸入することなく
表面に付着保水し得ると共に、外力により容易に破れう
る包材に納めてなる静的破砕カプセルである。That is, the present invention provides a static crushing agent containing calcium oxide as a main component in a packaging material that can adhere to the surface and retain water without water or an aqueous solution passing through or infiltrating, and can be easily torn by external force. It is a crushed capsule.
本発明に用いる酸化カルシウムを主成分・−する静的破
砕剤は、従来から用いられている一般的なものであり、
詳しくは酸化カルシウムにｃ、５（３ＣａＯ・Ｓ ｉ
Ｏｚ ）の如き水和調整物質等を加えて高温下で焼結し
たり、粉状物を圧縮成形したもの、あるいはこれら成形
粒を任意の粒度に調整したもの等がある。The static crushing agent mainly composed of calcium oxide used in the present invention is a conventionally used general one.
For details, calcium oxide has c, 5 (3CaO・S i
Examples include sintering at high temperatures with the addition of a hydration-adjusting substance such as Oz), compression molding of powder, and molded particles adjusted to a desired particle size.
本発明に用いる静的破砕剤を納める包材は、所定の水量
が付着保水するような材質でありかつ付着した水が容易
に透過又は浸入しないことが必要である。The packaging material containing the static crushing agent used in the present invention must be made of a material that can adhere to and retain a predetermined amount of water, and must not allow the adhered water to easily permeate or infiltrate.
この様な包材としては、例えば、ポリアクリル酸のアル
カリ塩等の水に膨潤したり、あるいは−部水に溶解する
等して、保水能を有する吸保水性物質を、ポリエチレン
、ナイロン等のプラスチックフィルムあるいはアルミ箔
等の金属フィルムと積層させた袋状の容器が挙げられる
。具体的にはこれら包材の保水量は、包村内に納められ
ている静的破砕剤１００ｇに対して８〜２５重量％が適
当であり、好ましくは１０〜１６重量％である。Such packaging materials include, for example, polyethylene, nylon, etc., which have a water-absorbing substance that has a water-retaining ability by swelling in water, such as an alkali salt of polyacrylic acid, or partially dissolving in water. Examples include bag-shaped containers laminated with plastic films or metal films such as aluminum foil. Specifically, the water retention capacity of these packaging materials is suitably 8 to 25% by weight, preferably 10 to 16% by weight, based on 100 g of the static crushing agent stored in the packaging material.
また、図面に示した本発明の一実施態様により説明する
と、静的破砕剤１を包む包材２は、内側に水不透過性の
プラスチックフィルム例えば水不透過性ポリエチレン３
、外側に吸保水性物質例えば変性アクリル高吸水不織布
４を被覆もしくは積層している。Further, to explain an embodiment of the present invention shown in the drawings, the packaging material 2 that encloses the static crushing agent 1 is made of a water-impermeable plastic film such as a water-impermeable polyethylene film on the inside.
The outside is coated or laminated with a water absorbing material such as a modified acrylic super absorbent nonwoven fabric 4.
本発明の静的破砕カプセルは、コンクリートや岩石を破
砕する際に、あらかじめ準備されている水容器内に浸漬

的破砕剤と接触し、主成分である酸化カルシウムと反応
して水和膨張を始め、その膨張圧力によりコンクリート
や岩石を破砕する。When crushing concrete or rock, the static crushing capsule of the present invention is immersed in a water container prepared in advance, inserted into a hole in the concrete or rock to be crushed, and then released into a rod-like shape from the top. When the packaging material is easily torn by being penetrated with an object, such as an iron rod, the adhering water comes into contact with the static crushing agent inside, reacts with the main component calcium oxide, and begins to expand due to hydration. It crushes concrete and rocks by applying pressure.
