DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method for landfilling waste, and more particularly, to a unit landfill for forming a unit landfill pit and a roof covering the unit landfill pit section, and then performing a landfill. The present invention relates to a waste landfill method capable of forming a pit section without being affected by the weather and performing a landfill operation of the waste while the roof is being relocated.

[0002]

2. Description of the Related Art Waste products such as incombustibles from general households and incineration ash discharged from incineration plants are finally transported to landfill sites such as bays to be landfilled.

[0003] However, in this waste landfill treatment, for example, there is a problem that it is necessary to secure a landfill site where a large depression is formed, and a large amount of waste is sanitarily sanitized near an urban area. It is expected that it will be difficult to secure land that can be used.

[0004] In order to cope with such a problem, for example, a waste landfill method as disclosed in Japanese Patent Publication No. 7-34900 has been proposed.

[0005] In this waste landfill method, first, a plurality of unit landfill pit sections are arranged from a starting point side to an end point side by partitioning a landfill site before construction where a waste is carried in and landfilled. I do.

Next, a section on the starting point side is formed to form a unit landfill pit, and a roof covering the upper part of the unit landfill pit is formed so as to be relocated.

[0007] Then, the waste is carried into the unit landfill pit below the roof for landfill, and a unit landfill pit section on the end point side adjacent to the unit landfill pit is created.

[0008] When the unit landfill pit covered with the roof is filled with waste that has been carried in and landfilled, soil covering is performed on the waste, and then the roof is placed on the adjacent unit landfill pit on the end point side. It is relocated and landfilled with waste while repeating landfill with waste and cover soil.

[0009] In this waste landfill method, a large amount of waste can be sanitarily disposed by such a configuration while securing land relatively easily and preventing intrusion of rain.

[0010]

However, in the above-mentioned conventional waste landfill method, since there is only one unit landfill pit covered by the roof, the unit landfill pit section to be subjected to the next landfill process is removed. The construction is affected by the weather, and there is a problem that waste cannot be landfilled while the roof is being relocated.

The present invention has been made in view of the above-mentioned problems of the conventional waste landfill method, by forming a unit landfill pit and a roof covering the unit landfill pit section, so that a unit for next landfill processing can be formed. It is an object of the present invention to provide a landfill method for waste that allows landfill pit sections to be created without being affected by the weather, and that allows waste landfill work to be performed even while the roof is being relocated. And

[0012]

In order to achieve the above object, the present invention provides a method for landfilling waste, comprising the steps of dividing a planned landfill site before construction where waste is carried in and landfilled, from a starting point to an end point. Forming a plurality of unit landfill pit sections arranged side by side, forming a section on the starting point side to form a unit landfill pit, the at least one unit landfill pit and an end point adjacent to the unit landfill pit A roof covering an upper part of at least one unit landfill pit section on the side is removably provided,
Under the roof, waste is loaded into the unit landfill pit on the starting point side for landfilling, and the adjacent unitary landfill pit section on the end point side is created and loaded into the unit landfill pit for landfilling. After the soil was covered on the waste, the roof was relocated to the unit landfill pit on the end point side and the unit landfill pit section on the end point adjacent to the unit landfill pit. The method is characterized in that landfilling with objects and soil cover and creation of unit landfill pit sections are sequentially and repeatedly performed.

According to this method, the roof covering the unit landfill pit and the upper part of the adjacent unit landfill pit section can be relocated, and the waste is loaded into the unit landfill pit below the roof. After reclaiming the land, constructing the unit landfill pit section, carrying it into the unit landfill pit and covering the waste on the landfill, then rebuilding the roof with the unit landfill pit and unit landfill pit Is relocated to the unit landfill pit section adjacent to the area, and landfilling with waste and cover soil and creation of the unit landfill pit section are sequentially repeated. The land reclamation can be performed without being affected by the weather, and the landfilling pit can be used to reclaim waste while the roof is being relocated.

BRIEF DESCRIPTION OF THE DRAWINGS FIG. 1 is a perspective view of a waste landfill method according to an embodiment of the present invention.

1 and 2 show an embodiment of the waste landfill method of the present invention. As shown in FIG. 2 (a), first, as shown in FIG. 2 (a), the waste landfilling method divides a landfill site before construction where the waste is carried in and landfilled, and a plurality of landfill sites arranged from the starting point side to the end point side. Unit landfill pit sections 1a-1e
To form The unit landfill pit sections 1a to 1e
The lengths in the arrangement direction are set to be substantially equal, and the intervals are set to be substantially equal.

1 (a) and 2 (b),
As shown in (c), a section 1a on the starting point side is formed to form a unit landfill pit 2a, and the unit landfill pit 2a and the unit landfill pit section 1b on the end point adjacent to the unit landfill pit 2a are formed. The roof 3 covering the upper part is formed so as to be relocated.

In this case, the roof 3 can be installed before the unit landfill pit section 1a on the starting point side is formed in the unit landfill pit 2a, or can be installed after the formation. . It is desirable that the roof 3 be provided with a side wall other than the top plate in order to prevent scattering and the like of the waste 4 carried and landfilled.

Then, as shown in FIG.
Under this, the waste 4 is loaded into the unit landfill pit 2a on the starting point side for landfilling, and an adjacent unit landfill pit section 1b on the end point side is created.

The construction of the unit landfill pit section 1b is as follows.
The construction is completed before the unit landfill pit 2a on the starting point is filled with the waste 4.

Further, as shown in FIG. 1 (c), when the waste 4 in the unit landfill pit 2a becomes full, a covering soil 5 is laid on the carried-in and landfilled waste 4,
Thereafter, the roof 3 is moved to the unit landfill pit 2b on the end point side and the unit landfill pit section 1c on the end point side adjacent to the pit 2b. In this case, the transfer of the roof 3 can be easily performed by a suitable means such as a crane. Note that a guide such as a rail for guiding the roof 3 may be laid so that the roof 3 can be easily relocated.

As a result, the roof 3 has been relocated by one pit, and the unit landfill pit 2b on the end point side has been constructed.
And the unit landfill pit section 1c on the end point side adjacent to the pit 2b.

Then, under the relocated roof 3, the waste 4 is carried into the unit landfill pit 2b for landfilling, and the adjacent unit landfill pit section 1c on the end point side is formed. 4 and the cover soil 5 to reclaim the unit landfill pits 2c to 2e and the unit landfill pit section 1d
To 1e are sequentially and repeatedly performed until the reclaiming of the last unit reclaim pit 2e is completed.

Thus, according to the waste landfill method of this embodiment, as shown in FIGS. 1 and 2, the roof 3 covering the unit landfill pit 2a and the upper part of the adjacent unit landfill pit section 1a is relocated. It is provided as possible, and under the roof 3, the waste 4 is loaded into the unit landfill pit 2a and landfilled,
Unit reclamation pit section 1a is created, and soil is covered on waste 4 which has been transported into unit reclamation pit 2a and landfilled, and then roof 3 is reclaimed with unit reclamation pit 2b and unit reclamation created. The unit is relocated to the unit landfill pit section 1c adjacent to the pit 2b, and the unit landfill pits 2b to 2e and the unit landfill pit section 1 by the waste 4 and the cover soil 5 are reclaimed.
Since the steps c to 1e are sequentially and repeatedly performed,
As shown in (a) and (b), the unit landfill pit sections 1a to 1e to be subjected to landfill processing can be created without being affected by the weather, and as shown in FIG. 1 (c). In addition, even during the transfer of the roof 3, the landfill work of the waste 4 can be performed in the unit landfill pits 2b to 2e created.

Although the waste landfill method of the present invention has been described based on the embodiment, the present invention is not limited to the configuration described in the above embodiment. Has described the roof covering one unit reclamation pit and one unit reclamation pit section. Alternatively, at least one of the unit reclamation pit or the roof covering the unit reclamation pit section may be replaced with two roofs. The above-mentioned unit landfill pits or the unit landfill pit sections are formed so as to cover them, or the adjacent pits are formed to have different sizes (in this case, pits having the same size are formed alternately). The configuration can be changed as appropriate without departing from the spirit of the invention.

[0025]

According to the waste landfill method of the present invention, a roof covering the top of a unit landfill pit and an adjacent unit landfill pit section can be relocated, and the unit landfill can be placed under the roof. After loading waste into the pit and reclaiming it, constructing the unit reclamation pit section, covering the waste loaded into the unit reclamation pit and covering the reclaimed waste, and then reclaiming the roof The pit and the unit landfill pit are transferred to the unit landfill pit section adjacent to the pit, and the landfill with waste and cover soil and the formation of the unit landfill pit section are sequentially repeated, so that the landfill processing is performed next. Unit reclamation pit sections can be created without being affected by the weather.While the roof is being relocated, waste can be reclamated using the newly constructed unit reclamation pits. It is possible to perform the landfill treatment of the object smoothly.
