2. Description of the Related Art Landfill is used as a final disposal method for industrial waste and household waste discharged from ordinary households. This land reclamation is done by constructing a waste disposal site in the inland areas such as the valleys in the mountains, or in the coastal areas. When landfilling waste at this disposal site, in order to prevent the infiltration of rainwater from the input of the waste to the time when the upper part is covered with the final soil,
It is called a closed system, and the whole or part of the disposal site is covered with a roof structure.

[0003]

[PROBLEMS TO BE SOLVED BY THE INVENTION] As a roof structure,
Steel truss frame structures, which are relatively easy to assemble and dismantle, are adopted, but if the disposal site itself is vast, it will have a long span, so the structure scale and strength will be limited, and the construction cost will be high. It had the drawback of being expensive.

In addition, when the disposal site is partially covered with a roof structure, measures against rainwater at other uncovered sites become a major issue, and after the landfill at that position is completed, another place is installed. However, if the scale of the roof structure is large, the refilling work will take time, and during that time, the landfill work will be interrupted and waiting time will be required until the relocation is completed. Was a factor of.

The present invention has been made in order to solve the above problems, and an object thereof is to realize a closed system at a low cost and to quickly replace the cover with relocation. It provides a waste disposal site.

In order to achieve the above-mentioned object, the present invention is directed to the above-mentioned opening in the upper surface of a waste disposal site where the bottom and the side wall connected to this are water-blocked and the upper surface is open. A roof structure that is laid across both sides in the width direction of the side wall and is movable along a direction orthogonal to the width direction, and a roof structure having an open bottom, and the waste disposal is movably arranged on both sides of the roof structure. A cover for opening and closing the upper opening of the field is provided, and an openable and closable waste inlet is provided on at least one surface of the roof structure. Therefore, according to the present invention, the roof structure is movable only at the waste input position required for landfilling, and the others are covered by the simple opening / closing type cover, so that the roof structure can be used for the disposal site area. The scale of the product is small, it can be constructed at low cost, and the relocation and re-covering work of the cover can be performed quickly.

Further, in the present invention, by disposing movably disposed inside the roof structure is a heavy machine for laying and rolling the waste put in the disposal site, so that the waste put in can be disposed. It is possible to level immediately from the input position.

Further, since the cover lid is a plurality of panel units installed movably over both sides in the width direction of the repository, the refilling work accompanying the relocation can be easily performed.

Furthermore, the cover is a cover sheet, and the cover sheet is drawn out between reels arranged on both sides of the roof structure and on both sides in the longitudinal direction of the repository.
By being arranged so that it can be wound, the front and rear openings of the roof structure can be automatically covered according to the movement of the roof structure.
