る。b. Conventional technology Static crushing agents are filled into the holes drilled in concrete or rock, which is the material to be crushed, and then increase in volume due to a chemical reaction to generate expansion pressure. It is a crushable drug. In general, the main component is calcium oxide, which is kneaded with water or put in a paper bag, absorbed into water, and then filled in the pores. Since the hydration reaction after filling proceeds without vibration and noise, it is widely used as a pollution-free crushing method in residential areas and around important facilities. The expansion time of a normal static crushing agent is 12 to 24 hours after filling.

い。On the other hand, a rapid static crushing agent with a shortened crushing time has recently been used. The quick-type static crushing agent generates crushing force in about one hour, but since the temperature in the hole becomes 100 ° C. or higher, various methods for preventing the jetting phenomenon have been adopted. The eruption phenomenon is that when the hole is unreacted and does not have sufficient binding force, the center of the hole reacts first and a large amount of steam is rapidly generated in the hole, which causes the crushing agent in the hole Is a phenomenon that erupts. Spraying is not preferable because it is very dangerous and crushing force is lost. There are two ways to prevent the eruption: a method in which the crushing agent is granulated to leave a gap after filling, and the generated steam is released from this gap. Agent), a reaction of the crushing agent is caused from the hole, and the plug is sealed from the hole. Generally, the crushing force obtained by the crushing method using a heat stopper at the hole is larger than the method using a granular crushing agent.

方法が提案されている。In addition, as a rapid crushing method that is not affected by environmental temperature,
Arrange the insulation to the entire length and the bottom of the drilled hole,
A method has been proposed in which a crushing agent is insulated and kept warm, and a thermal stimulus is applied to the opening.

The problem to be solved is to fill the hole with a heating plug, if the operating temperature, that is, the temperature of concrete or rock, is low, the heat generated by the heating plug is cooled by concrete or rock and sufficient heating is performed. The effect cannot be given to the crushing agent, and the effect of preventing jetting may not be exhibited.

なる。When the heat insulating material is inserted into the whole hole to keep the crushing agent warm, firstly, the expansion pressure generated by the hydration of the crushing agent reaches the material to be crushed through the heat insulating material. Has a disadvantage that the crushing force is reduced because the amount of the crushing agent is reduced by the amount of the heat insulating material or the amount of the crushing agent is reduced by the amount of the heat insulating material. The central part is easier to store heat, so if there is less heating from the opening, or if water or air remains between the heating stopper and the crushing agent and the heat transfer becomes poor, the ejection phenomenon will occur. Occurs and becomes very dangerous. Third, since the inside of the perforation is not always smooth, inserting the heat insulating material to the bottom of the hole is troublesome and may not be possible. If the heat insulating material pipe or the like is made thinner to facilitate insertion, the gap between the hole wall and the heat insulating material increases, which is a disadvantage that the crushing force is reduced.

得て本発明を完成するに至った。d. Means for Solving the Problems The present inventor accumulated heat of hydration of the heating stopper and conducted various studies in order to find an effective method for preventing jetting. As a result, the heat insulating layer was wound around the opening. And found that it is effective to use a method in which a heating stopper is filled and a method in which the heating stopper is previously placed in a container with a heat insulating layer and encapsulated, and the present invention has been completed. .

る。The heating stopper 5 may be any agent that generates heat due to a chemical reaction, but generally uses quicklime as a main component from the viewpoint of heat generation, economy and handling. The reaction start time of a commercially available heating stopper is determined by the activity of quicklime, the addition of a reaction accelerator and a reaction retardant, the addition of quicklime, the granulation of quicklime, and the surface of quicklime particles so that the working time required to fill the pores can be secured. It is adjusted by appropriately selecting a coating (by a resin paint or the like) and the like.

ため迅速な破砕効果を上げられないなどの欠点が生じる
ので好ましくない。The heat insulating material sheet 4 of the present invention is preferably a sheet material such as foamed polyethylene, foamed polystyrene, plastic, felt, paper, cork and the like. The thickness depends on the thermal conductivity of the heat insulating material, but is preferably 0.2 to 3 mm. If it is less than 0.2, it is difficult to form a uniform heat insulating layer when the heating stopper is filled, and the heat insulating effect becomes insufficient. If it exceeds 3 mm, the friction between the heating stopper and the hole wall is reduced, reducing the original purpose of the stopper effect, making it easier to erupt, and at the time of reaction after filling the heating stopper. It is not preferable because it raises a space between the crushing agent and the crushing agent, so that the reaction heat of the heating stopper can not be sufficiently conducted to the crushing agent, so that the crushing effect cannot be improved quickly.
第２図は、第１図における断熱材シート４と加熱止栓
剤５の部分をカプセル化した加熱止栓剤カプセルの断面
を示す。FIG. 2 is a cross-sectional view of a heat stopper material capsule in which the heat insulating material sheet 4 and the heat stopper material 5 in FIG. 1 are encapsulated.

側面に断熱材シート７を内接させたのち、該断熱材シー
トの内側に加熱止栓剤８を所定量つめ、入口を封印テー
プ９で止めて作製する。In the heating stopper plug capsule, first, a bag 6 of a predetermined shape is made of a thin water-permeable sheet of paper or cloth, and a heat insulating sheet 7 is inscribed on the inner surface of the bag. A predetermined amount of the heat stopper 8 is filled inside the sheet, and the inlet is closed with a sealing tape 9 to produce the sheet.
加熱止栓剤カプセルの直径Ｄは、穿孔径より５〜15mm

ましくない。The diameter D of the heat stopper capsule is 5 to 15 mm from the diameter of the perforation.
A small one having a length L of 50 to 150 mm is easy to use. If it is smaller than this, the calorific value will be insufficient and the thermal stimulus will be insufficient, and if it is larger than this, it will be difficult to achieve close packing, which is not preferable.

等の効果が得られる。The width l of the heat insulating material sheet 7 is shorter than the length L of the side surface of the bag as shown in FIG.
Preferably, there is no heat insulating sheet in 10. This is because, when the heat insulating material sheet is present to the bottom, when the heat blocking agent capsule is filled, the heat insulating material sheet may enter the boundary surface between the crushed material and the heat blocking agent to deteriorate the heat conductivity. Even if the heat insulating material sheet 7 is attached to the outer surface of the bag 6, the same effect can be obtained.

る。e. Function In practicing the present invention, a perforation 2 is formed in a rock 1 and a static crushing agent 3 is loaded while leaving the entrance of the hole 2 at a certain depth, and then a heat insulating sheet 4 is applied to the entire inner wall of the hole. Is wound so as to cover it, and the heat-insulating stopper 5 containing water is filled.
すると、まず加熱止栓剤５が水和反応を起こして発熱
し、その熱は静的破砕剤３を加熱し、静的破砕剤３は順
次に孔２の深部に向けて反応し、膨脹する。そのさい、
加熱止栓剤５と被破砕物１の孔壁との間に断熱シール４
による断熱層を有するので、加熱止栓剤の水和熱は放熱
されにくく、また使用環境温度の影響、特に低温での外
部からの冷却作用を受けにくい。Then, first, the heating stopper 5 causes a hydration reaction to generate heat, and the heat heats the static crushing agent 3, and the static crushing agent 3 sequentially reacts toward the deep part of the hole 2 and expands. . At that time,
A heat insulating seal 4 between the heating stopper 5 and the hole wall of the material 1 to be crushed.
, The heat of hydration of the heating stopper is hardly dissipated, and it is hard to be affected by the ambient temperature of use, particularly, the cooling action from the outside at a low temperature.
したがって、まず、加熱止栓剤５が強固に孔口を塞
ぎ、噴出現象を生じることがない。Therefore, first, the heating stopper 5 firmly closes the hole and does not cause the ejection phenomenon.
また、第２図に示す加熱止栓剤カプセルは、第１図に
おいて、静的破砕剤３を孔２内に装填したのち、カプセ
ルに水を含ませてから、孔口に密接に装填する。In addition, the capsule for heating stopper shown in FIG. 2 is prepared by loading the static crushing agent 3 into the hole 2 in FIG. 1, filling the capsule with water, and then closely loading the hole into the hole.
装填された加熱止栓剤カプセルは、孔壁の間に断熱シ
ール７による断熱層ができるので前もって断熱材シール
４を孔側壁面に設置したのと同様の作用が得られる。Since the heat-blocking agent capsule thus loaded has a heat-insulating layer formed by the heat-insulating seal 7 between the hole walls, the same effect as when the heat-insulating material seal 4 is previously installed on the hole side wall surface can be obtained.
