Description

[Detailed Description of the Invention] << Industrial Application Field >> The present invention relates to a wall for a waste disposal site, and particularly to a structure in which the wall has a function of discharging gas discharged from waste to the outside. Regarding

<Prior art> As is well known, landfill disposal is generally adopted as the final disposal of general waste and industrial waste, and such waste disposal sites are provided inland or in the mountains. Has been.

By the way, in constructing this type of disposal site, for example, a recess for introducing waste is provided by excavation or the like.

Then, the waste is sequentially put into the formed recesses to be compacted, and when the final soil is covered on the uppermost part, the upper part of the disposal site is used as a park, a green space or the like.

However, if a waste disposal site is constructed in this way,
There was a problem that the upper part could not be used for a long period of time, or the injected waste was scattered and deteriorated the surrounding environment.

Therefore, the present applicant has proposed a method for constructing a waste disposal site capable of solving such a problem, as shown in Japanese Patent Application No. 63-132595 (see Japanese Patent Application Laid-Open No. 1-304092).

The method of constructing a waste disposal site according to this proposal is characterized in that an artificial ground is constructed in advance above a recess into which waste is put, and the waste can be dumped into the space below it.

However, if the upper part of the recess is covered with artificial ground in this way, the inside of the recess becomes a substantially sealed space, and the gas and dust emitted from the waste deteriorates the working space. Exhaust equipment was required to discharge dust to the outside, but this had the following problems.

<Problems to be solved by the invention> That is, as exhaust equipment, for example, if a suction blower or the like is provided on the waste to be thrown in, the deterioration of the work space can be improved, but such means have already accumulated. There is a problem that the gas released from waste cannot be discharged.

Therefore, it is conceivable that the wall body that supports the artificial ground surface has a double structure, and a through hole that communicates with the inside of the double wall structure is formed inside the wall body and that this is used as an exhaust pipe.
Since a large number of through holes have to be provided in order to function as an exhaust pipe, there is a problem that the strength of the wall body is reduced.

The present invention has been made in view of the above problems, and an object thereof is a wall body for a waste disposal site capable of ensuring a function as an exhaust pipe without significantly reducing the strength of the wall body. Is provided.

<< Means for Solving the Problems >> In order to achieve the above object, the present invention relates to a wall body for supporting artificial ground constructed on a recess into which waste is thrown, in which the wall body has a hollow portion. With a wall body with a double wall structure,
Porous coating layers on both sides of the wall body, extending above the lower bottom portion of the recess and extending to the lower surface of the artificial ground, and inside the double wall structure of the wall body and each coating It has a communication hole for communicating the layers.

Further, in place of the covering layer and the communication hole, a covering panel attached at a predetermined distance from the inside to a portion above the lower bottom portion forming the recess of the wall body, and the covering panel. It may be composed of a large number of through holes.

<Operation> According to the wall body having the above configuration, since the porous coating layer that communicates with the inside of the wall body is attached to the wall body, the gas and dust emitted from the waste are generated inside the coating layer. Is discharged upward through the.

Therefore, it is possible to reduce the number of communication holes for communicating the coating layer with the inside of the wall body.

Further, when a porous coating panel is attached to the wall body at a distance, this gap portion serves as an exhaust passage for gas and the like. Therefore, it is not necessary to provide a communication hole in the wall body.

<< Embodiment >> A preferred embodiment of the present invention will be described in detail below with reference to the accompanying drawings.

1 to 3 show an embodiment of a wall body used for constructing a waste disposal site according to the present invention.

The wall body 10 shown in the figure is used to construct a disposal site for the waste 12 as shown in FIG.

In the construction of the repository shown in the figure, the recess 14 for containing the waste 12 is formed by excavating the ground 16.

When the recess 14 is formed, a water impervious sheet 18 made of synthetic rubber or a synthetic resin sheet is laid on the upper surface of the ground 16 in the recess 14. After laying the water blocking sheet 18, the plurality of wall bodies 10 are constructed. The foundation portion of the wall body 10 is formed in the ground 16 by inserting the water-blocking sheet 18.

Further, an artificial ground surface 22 is constructed on the upper part of the wall body 10 through the beam 22a, and a thin embankment 24 is constructed on the artificial ground surface 22. A waste input port 26 is provided for each space partitioned by the body 10.

The wall body 10 has a wall main body 10a made of reinforced concrete and a wall main body 10 as shown in cross sections in FIGS.
On both sides of a, the bottom bottom portion of the wall body 10a that constitutes the recess 14, that is, the upper surface of the water-impervious sheet 18 extends from the upper surface to the beam 22a of the artificial ground 22 and is attached to the porous body. It is composed of a coating layer 10b.

The wall body 10a has a double wall structure, and a space 10c is formed in the center portion in the thickness direction along the longitudinal direction, and the space 10a and the coating layer 10b are provided on both sides of the wall body 10a. A communication hole 10d for communicating with each other is formed.

The coating layer 10b is made of, for example, high-porous glass wool or steel wool, and when the wall body 10a is cast into the ground 16, the coating layer 10b is
It is provided in the part exposed from.

In addition, at the upper portion of the wall body 10 and at right angles to each wall body 1
A pipe 26 that connects the 0 space portions to each other is connected, and an intake blower (not shown) is connected to the pipe 26.

When the disposal site is constructed as described above, the waste 12 is loaded into the recess 14 through the loading port 26.

The discharged exhaust 12 is compacted by the bulldozer 28, and is sequentially deposited in the recess 14 from the lower side.

At this time, the wall 10 is gradually buried in the waste 12, but the gas and dust emitted from the waste 12 are filtered by the porous coating layer 10b, and then passed through the communication hole 10d to pass through the wall body 10a. It reaches the inside of the hollow and is discharged to the outside through the pipe 26.

In this case, especially the space 10 between the coating layer 10b and the wall body 10a
Even if the number of communication holes 10d communicating with c is reduced, the gas circulates from the entire coating layer 10a by the negative pressure of the supply air and enters the space 10c, so that the generated gas can be sufficiently discharged.

Therefore, it is possible to avoid a large reduction in strength of the wall body 10a due to the opening of the communication hole 10d.

FIG. 4 shows a second embodiment of the present invention, and only the characteristic points will be described below.

In the example shown in the figure, instead of the coating layer 10b of the first embodiment, the coating panels 30 are attached to both sides of the wall body 10a with a predetermined gap.

The covering panel 30 is made of, for example, a thin steel plate or a synthetic resin plate having a large number of through holes 36 formed therein, and the wall body 10a.
Is disposed above the tip end portion that is fitted into the ground 16, and is attached to both side portions of the wall body 10a with the partition walls 32 that come into contact with the outer side portion of the wall body 10a being interposed therebetween. Exhaust space 3 between 10a
4 is forming.

Further, in this example, it is sufficient to ventilate the entire internal space of the disposal site without providing a gas exhaust pipe.

In the wall body 10 having the above structure, the gas or the like released from the waste 12 is discharged to the outside through the space 34, and it is not necessary to provide a communication hole in the wall body 10a. Since it is not necessary to form a space inside as a double wall structure, the strength of the wall body 10 is not reduced at all.

<< Effect of Device >> As described in detail with reference to the embodiments above, in the wall material for a waste disposal site according to the present invention, the number of through holes for degassing formed in the wall member is greatly reduced. Alternatively, since it is not necessary to provide the gas at all, the gas generated from the waste can be discharged to the outside without significantly reducing the strength of the wall body supporting the artificial ground surface.
