破砕物を破砕する静的破砕剤に関する。[Detailed Description of the Invention] [Field of Industrial Application] This invention is a static method that crushes the material by loading it into a crushing hole drilled in a material to be crushed, such as concrete or rock, and using hydration energy. Regarding the crushing agent.
生石灰等を主成分とする静的破砕剤は、粉、粒状等で用
いられるほか、破砕孔に装填するに適した寸法、重量の
袋詰めあるいはカートリッジ詰め等の包装体となして用
いる場合が少なくない。Static crushing agents whose main ingredient is quicklime etc. are used in the form of powder, granules, etc., and are rarely used in packages such as bags or cartridges with dimensions and weight suitable for loading into crushing holes. do not have.
しかし、静的破砕剤は使用時点までは乾燥状態で保管し
なくてはならないし、使用時点では水と均等に接触し、
計画された水和反応をスムーズに起さなくてはならない
。However, static crushing agents must be stored in dry conditions until the point of use, at which point they are in even contact with water;
The planned hydration reaction must occur smoothly.

透水性のフィルム等で包装し、使用に際し包装を破り水
和反応させる方法等が提案されている。Conventionally, the crushing agent was stored in a water-permeable packaging material to facilitate loading into the crushing hole and control of the hydration reaction, or the crushing agent was packaged in a water-impermeable film, etc., and then wrapped before use. Methods have been proposed to break the hydration reaction and cause a hydration reaction.
しかし、いずれの方法も、乾燥状態での保管が容易で、
使用に際し、水と均等に接触し易く、水和反応を正確に
制御できる等の条件を備えたものではなかった。However, both methods are easy to store in a dry state,
When used, they did not meet the conditions of easy and even contact with water and accurate control of the hydration reaction.
この発明は上記問題点に着目しなされたものである。そ

応の制御が適確にできる静的破砕剤を提案するにある。This invention has been made in view of the above-mentioned problems. Its purpose is to easily store it in a dry state, and when using it,
The object of the present invention is to propose a static crushing agent that can be brought into even contact with water and can accurately control the hydration reaction within the crushing pores.

なし、水と均等に接触させることができる。フィルム厚
みは１０〜５０μのものが好適に用いられる。The uniaxially stretched film used in this invention is made from a thermoplastic resin, preferably high-density polyethylene or polypropylene. A uniaxially stretched film of high density polyethylene or polypropylene has a low water vapor permeability and can be easily packaged airtight by heat sealing, allowing the crushing agent to be stored in a dry state. In addition, it is easily torn along the stretching direction, so after loading into the crushing hole, the packaging material can be made with many tears along the stretching direction, and the crushing agent inside can be broken up and brought into even contact with water. . A film having a thickness of 10 to 50 μm is preferably used.

破砕作用を発揮した。In Figure 1.2, a crushing agent 1 containing quicklime as a main component is applied to a high-density polyethylene film having a thickness of 20 μm and a -axially stretched film 2.
35mm in diameter and approximately 10CI in length, airtightly packaged.
11 packages 3 having a circular cross section were loaded into a horizontal crushing hole 5 bored in a concrete object 4 to be crushed. After this package 3 was pushed to the bottom of the crushing hole 5, it was pushed somewhat forcefully with the insertion rod 6, and a large number of cracks 7 were generated along the uniaxial stretching direction in the -axially stretched film 2, causing internal fractures. Agent 1 fell apart. The crushing hole 5 is closed with a plug 8, and the L that passes through the plug 8
When water was injected from the upright tip of the tube 9, the crushing agent 1 evenly contacted the water and caused a hydration reaction, exhibiting the planned crushing action.
この発明の静的破砕剤は一軸延伸フィルムを用い気密に
包装しであるので、長期間にわたり、乾燥状態を保ち劣
化することなく保管ができる。Since the static crushing agent of this invention is airtightly packaged using a uniaxially stretched film, it can be stored in a dry state for a long period of time without deteriorating.

揮できる。In addition, in use, after being loaded into a crushing hole, the uniaxially stretched film can be pushed with an insertion rod or the like to generate a large number of cracks in the uniaxially stretched film. Compared to packaging with ordinary film and cutting it open with a cutter, it is easier to create multiple cracks and bring the crushing agent into contact with water quickly and evenly. can be accurately exerted as crushing force.
