大差なかった。[Prior art] A method of statically crushing a brittle object by filling a slurry of a static crushing agent into a hole drilled in a brittle object of rock or concrete and utilizing the expansion pressure generated by the hydration reaction. Was being conducted. However, the mixing time of the static crushing agent slurry may be long or the hole diameter may be larger than necessary, and a part of the hole partially expands the fragile part by compressed air at the time of so-called pocket (gama). When a large void called "is generated, it was very dangerous because the phenomenon of jetting was accompanied by the heat of hydration generated during the hydration reaction. Further, since the crushing agent generally has a high hydrogen ion concentration, it causes rough skin when contacting the skin. In particular, it was dangerous to get in your eyes due to splashing when mixing with water. Therefore, it has been tried to put the crushing agent in a water-permeable paper bag, etc., and put the material that has penetrated into the water in the holes that have been drilled, but it is necessary to stuff it with a stick, etc. It didn't make much difference.

として破砕時間が長くなる欠点があった。[Problems to be Solved by the Invention] Since the static crushing agent causes a hydration reaction immediately upon contact with water, it cannot be solidified using water. However, in order to solidify with only the crushing agent powder, molding at the time of compression perforation under high pressure is possible, but the bulk specific gravity becomes large, and the water absorption is poor even if water is injected after loading the pores, The Japanese reaction was delayed, resulting in a long crushing time.

出し本発明を完成するに至った。The present invention has been made to solve such drawbacks, and has a point in using an organic solvent which is a non-aqueous binder. When a static crushing agent is kneaded with an organic solvent and left to stand, the solvent evaporates. As a result, they found that the crushing agent solidified, and completed the present invention.

After the insertion, there is a static crushing method characterized by injecting water in the absence of water.

Alternatively, water may be injected to insert the crushing agent into the filling hole. The presence of water means that there is water beforehand such as the sea floor. Since this rod-shaped solid agent has a bulk specific gravity of 1.0 to 2.0, it easily absorbs water and immediately causes a hydration reaction, which causes an expansion pressure to be exerted, so that a crushing effect equivalent to that of the conventional method can be obtained.

The bulk specific gravity of the statically crushed solid agent is preferably in the range of 1.0 to 2.0. By adjusting the bulk specific gravity to this range, absorption of water is facilitated and the hydration reaction is not extremely delayed. It is desirable that the statically crushed solid agent has a shape which is smaller than the diameter of the filling hole of the non-crushed material by about 1 mm or more and has an arbitrary length.
