Synthetic resin powder and various industrial waste can be stored in addition to incineration ash so as to eliminate the generation of a polution problem.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a container for accommodating various industrial wastes and wastes such as garbage, and a method for treating the container.

[0002]

2. Description of the Related Art At present, as a method for treating incinerated ash and other industrial waste discharged from a combustion furnace of a factory or a waste treatment factory, for example, a method of constructing a dam and dumping it into the dam is adopted. ing.

[0003]

However, in such a treatment method, when the amount of discarded waste increases, the environment may be damaged and pollution may occur, and a countermeasure against it has been desired.

[0004] The present invention has been made in view of such circumstances,
It is an object of the present invention to provide a waste storage container that does not cause pollution problems and a method for treating the waste storage container.

[0005]

According to the present invention, means for solving the above-mentioned problems are constituted as follows. First
The invention is characterized in that it is composed of a rectangular container body with an open upper part, and a lid body that covers the container body in a sealed state.

The second aspect of the invention is characterized by comprising a spherical container body having an opening and a lid capable of closing the opening.

In the third aspect of the invention, after closing the waste storage container in which the waste is stored, the waste storage container is placed in the recess and the filling filler or the spray filling material is placed in the recess. It is characterized by being injected or sprayed to be solidified and buried.

In the first and second aspects of the present invention, the problem of pollution can be prevented by storing the waste in a sealed state so as not to leak outside.

In the third aspect of the present invention, more appropriate environmental protection is achieved by throwing the container containing the waste into the recess and solidifying the container with the spray filler.

[0010]

Embodiments of the present invention will be described below in detail with reference to the drawings. 1A is a perspective view of the waste container 1, and FIG. 1B is a cross-sectional view thereof.
Is a container body that is formed in a rectangular shape with the upper part open, and 3 is a lid that covers the container body 2.
In each case, concrete is poured into both sides of the mesh-shaped metal core material m to have a high rigidity with a thickness of about 8 to 10 cm, and the outer shape is formed to a size of about 1 m × 1 m.

On the periphery of the lid body 3, there are formed bolt holes 5, ... Through which the stud bolts 4, ... Planted in the upper portion of the container body 2 are inserted, and by fastening the nuts 6 ,. The lid can be closed. Such a waste container 1 is easy to manufacture, can be obtained at low cost, and has high rigidity. In addition, for example, when incineration ash is put in as waste, a large amount can be packed by mixing water and pressing.

The waste container 1 containing the waste is stored in, for example, a pit 7 (see FIG. 2) of an abandoned mine or a hole formed by a falling rock or the like, and a lightweight concrete as a pouring filler is poured therein. By doing so, it can be buried as a solidified state.

The lightweight concrete includes cement, sand,
It is a mixture of water, a foaming agent, air, etc. (for example, the product name "Acecon" of Fuji Acecon Industry Co., Ltd.),
As shown in FIG. 2, a squeeze pump vehicle 13 is used to produce aerated lightweight concrete supplied in a kneaded state from a screw mixer vehicle 12 connected to an air bubble generator 11.
To be injected together with air to the injection site. By the way, Table 1 shows the mixing ratio of this lightweight concrete.

[0014]

[Table 1]

In addition, as an injectable filler (lightweight concrete) using incineration ash, a porous incineration ash obtained by burning paper sludge and wood chips at a temperature of 750 to 800 ° C. and a porous incineration ash are used. On the other hand, it is composed of 20 to 30% by weight of cement, 0 to 35% by weight of pea gravel with respect to the porous incinerated ash, 0 to 40% by weight of sand with respect to the porous incinerated ash, and an appropriate amount of water. A kneaded product can also be used.

Further, in addition to the above-mentioned lightweight concrete, cement is mixed with water and sand in an appropriate amount by the sand pressure feeding method to generate bubbles (for example, "Ace Sand", a product name of Fuji Acecon Industry Co., Ltd.). May be used. Alternatively, mortar or the like may be used as the spray filler.

According to such a treatment method, the surrounding is not polluted, the ground is improved and solidified, and the ground subsidence due to the drop or the consolidation can be prevented. Further, even if the recess has a complicated shape, it is possible to completely embed it, which is the most suitable for solidifying the ground.

The waste container 1 may be made of iron plate, plastic or the like.

FIG. 3 shows a different embodiment of the waste container 1, which is formed by molding a synthetic resin material such as a vinyl chloride resin material, for example, with a thickness of 6 to 9 mm and an outer diameter of about 1 m, and an opening 2a at the top. Forming a hollow spherical container main body 2 having the opening 2a, and inserting the studs 4 implanted in the periphery of the opening 2a into the bolt holes 5, formed in the lid 3 to fasten the nuts 6 ,. The lid can be closed by.

Further, in FIG. 4, a screw groove is formed in the lid body 3 and the opening 2a of the container body 2 so that the lid body 3 can be screwed, so that the lid closing work becomes easier. There are advantages.

Needless to say, the waste container 1 described above can store powder of synthetic resin and various industrial wastes in addition to the incinerated ash described above.

[0022]

As described above, according to the waste container of the present invention, the waste can be stored in a sealed state.
It can be provided inexpensively without causing pollution problems.

Further, by embedding the waste container in which the waste is stored in the recess in a state of being solidified with the injection filling material or the spray filling material, environmental protection can be achieved and the ground can be improved.
