Description

DETAILED DESCRIPTION OF THE INVENTION The present invention provides a crushing capsule suitable for use in crushing rocks, concrete structures, etc.

In recent years, expansible crushing compositions capable of static destruction have been widely used in place of explosive materials such as dynamite for crushing rocks and demolishing concrete structures.

The above-mentioned crushing K[ is used as an acid ray, and IQ is used for 2 and 7jl.
Mix it with the water from the leaves and fill it into the hole in the crushed object. As a result, the water-containing crushing composition progresses in hardening in a short period of time due to heat generation X, and at the same time expands and generates a force that pushes out the holes of the object to be crushed, thereby crushing the object. Therefore, it is important to use a crushing composition such as C'(C').

The following will explain A: Invention A R1.

The uninvented crushing capsule is made from a crushing composition (hereinafter referred to as crushing material) made of a material that is impermeable to 7K and sealed in a container.

In the present invention, as a crushing material, lime-based compounds (table compounds, Silica sand salt, calcium oxide, and lime-based inorganic compounds (C7tY organic compounds [e.g.
It instantly absorbs several times as much water as your car and becomes gel-like.
The gel has a water retention property of 4 against some pressure, and a super absorbent resin that is insoluble in water (Aqua Cube, product name, Sumikagel 5-50, product name 9, etc.) is added and mixed, and it is usually used in one quantity. It is used in powder form.

In addition, as the non-water permeable material for forming the container, various non-water permeable materials can be used, such as polystyrene resin or waterproof paper, but materials with some degree of rigidity are preferred. It is.

The arrows indicate an embodiment of the present invention, which will be described with reference to the drawings.
Container 2 is material for crushing. The container 1 is formed in the shape of a solid cylinder, and consists of a cylindrical peripheral wall 1a and lids 1b, 1b that seal both ends of the peripheral wall 1a.

The container 1 is made of a material that is impermeable to water, for example, a synthetic resin such as polystyrene resin. In addition, the outer diameter d and length l of the container 1 can be selected depending on the purpose of use, and usually the outer diameter is several 10rnr.
n, length number] approximately QQmm. In this embodiment, the peripheral wall 1a is made of polystyrene resin with a thickness Q of 2 mm, an outer diameter d of the container is 32 mm, and a length l.
is formed to be 5QQmm.

The crushing material 2 is a mixture of calcium aluminum tuberite and free calcium oxide, etc., and is used in powder form. This crushing material 2
Depending on the amount filled into the inside of the container 1, the water content characteristics (changes in water content over time, etc.) during water absorption, which will be described later, can be changed.

Therefore, the filling liquid for the crushing material 2 can be changed depending on the purpose of use.

The crushing cover/l/A configured as described above fills the crushing material 2 into the water-impermeable container 1.
Since it is sealed, the crushing material 2 does not absorb moisture even in a humid environment and can be easily stored.

In brief, the crushing method for using the above-mentioned crushing capsule A) will be explained.

During the crushing work, the required number of holes are drilled in the object to be crushed using a rock drill at predetermined intervals, as in the past. The diameter of the hole may be slightly larger than the outer diameter d of the crushing capsule to be used (d+2 to 3 mm).

Next, apply imm to the entire peripheral wall of the required number of crushing capsules.
A large number of small holes (diameter 0.] to Q, about 4 mm) are made at intervals of . This drilling work is performed as shown in Figure 2 (at, [
It is easy to use a perforator B as shown in bl. This perforator B has a cylindrical body divided into two parts along a plane passing through its axis, and two gutter-shaped members 4 and 4' connected to each other so as to be openable and closable.
A large number of needles 5, 5, . In order to perforate the capsule A for crushing with this perforator B', the member 4.4"r
In the open state, there is a crushing capsule AY inside the 10,000 member 4.
It is placed and closed by the other member 4' and pressed from the outside.

As a result, a large number of small holes can be easily bored on the outer peripheral surface of the crushing capsule.

Immerse the crushed capsule AY with a hole in the water.

As a result, the crushing material 2 inside the container 1 absorbs water that enters through the many holes. At this time, the moisture content of the crushing material 2 can be changed by changing the immersion time. The water content of the crushing material 2 is desirably 25 to 35%, and in this example, the immersion time may be about 3 to 5 minutes. Next, absorb water and crush one capsule A.
Insert it into each hole of the material to be crushed and poke it with an iron rod etc. to evenly fill the hole. In addition, if the hole is deep, it is sufficient to fill the crushing capsule A7 with an additional number of capsules if necessary. In such a filling operation, the crushing capsule A described above can easily fill deep holes without damaging them.

In the crushing capsule A filled into the object to be crushed as described above, the crushing material 2 inside hardens with heat generation, and at the same time expands to crush the object.

According to the crushing capsule A described above and the crushing method using this capsule/I/Aχ, the capsule for crushing is perforated in the peripheral wall, and after that, it is immersed in water and filled into the hole of the object to be crushed. Since it can be constructed with a simple process of doing this, it is possible to improve the efficiency and accuracy of the crushing work, and as a result, planned construction becomes easier.

Since equipment such as a kneading mixer is not required, work safety can be improved, and since the crushing material does not adhere to the equipment, there is no material loss and it is economically superior. Furthermore, according to the crushing capsule of the present invention, it is possible to avoid problems during summer and winter.
The influence of temperature differences on the material to be crushed can be eliminated by adjusting the water temperature when immersing the capsule. Therefore, the work can be carried out regardless of environmental conditions such as climate. Furthermore, even when the work is carried out underwater, the work can be carried out without any dispersion of the slurry, and work can be easily carried out when the holes in the material to be crushed open downward. Koto IC
and has many advantages.

In addition, in the above embodiment, the shape of the container is cylindrical, and Ml is used by being filled into a hole drilled in the object to be crushed. However, the present invention is not limited to this. It can also be used by inserting it into cracks in rocks.

The present invention will now be explained in more detail by way of an experimental example.

[Experimental Example 1] Using a cylindrical container with a diameter of 32 mm and a length of 500 mm, which was made of a polystyrene resin sheet ρ) with a thickness of 0.2 mm, 700 g of crushing material was filled inside the container, and both ends were closed with rubber stoppers. A capsule for crushing was made by sealing.

A granite cube with a side of 90 cm and a cube of unreinforced concrete with a side of 1 m were used as objects to be crushed, and holes with a hole diameter of 35 mm and a hole length of 7 Q cm were bored at intervals of about 2 Q cm. The entire side wall of the capsule for crushing the soil was perforated using the perforator shown in FIG. Fill each hole in the granite and unreinforced concrete with a crushing capsule, and poke it several times with an iron rod to ensure uniformity. Furthermore, fill each hole with one more crushing capsule in the same manner as described above, until the opening of each hole is completely filled with zero. Granite and unreinforced concrete similar to those described above were filled with crushing materials.

The time required for crushing and the state of destruction of each of the above-mentioned materials to be crushed was investigated.1 As a result, there was almost no difference between the method using capsules of the present invention and the kneading injection method. The results regarding the crushing time are shown in the arrow table.

From the experimental results described above, it appears that the crushing capsule according to the present invention can achieve the same crushing effect as the conventional cross-contact and injection method with extremely simple operations. Therefore,
It can be seen that the work can be simplified and efficiency can be improved.

[Experimental Example 2] Two types of crushing material to be filled into containers of the same size were prepared using different fires, each was immersed in water, and the change in moisture content over time was investigated. Dimensions of the container used (working diameter 32mm, length 5QQmm, filling ft (one cup is 630g, the other is 700g).
As shown in the figure. In the figure, curve C is the result for a capsule filled with 630 g, and curve d is the result for a capsule filled with 700 g. As can be seen from the figure, all of the capsules reach a water content of about 100% in 5 to 7 minutes, and by changing the filling amount, it is possible to create capsules with desired water content characteristics.

As described above in detail, the capsule for crushing according to the present invention is a hollow columnar container made of a material impermeable to water and filled with crushing material.

It is a sealed item. A crushing method using this crushing capsule is a method in which the capsule is used by drilling a number of small holes and immersing it in water, and then filling it into the object to be crushed. It has many advantages.
