DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a waste disposal site and a waste disposal method that do not adversely affect the environment due to sewage or the like in waste disposal.

[0002]

2. Description of the Related Art As is well known, the final disposal site of waste is
Landfills for general waste and industrial waste are roughly divided into two types. Landfills for general waste are particularly landfilled with waste, which is called a managed landfill, and the leachate generated from this landfill is What has processing equipment etc. is applied. Although such landfill disposal is a simpler disposal method than incineration disposal, it requires expensive facilities for treatment and management of leachate, and has disadvantages such as land subsidence in the use of landfill sites. Had.

In recent years, a technique for compressing and fixing waste in a block shape (for example, a technique described in Japanese Utility Model Application Laid-Open No. 2-97997) has been put to practical use, and the solidified waste (hereinafter, referred to as a solid waste) has been developed.
Solidified waste) is compressed and has a property that it is difficult for rainwater or the like to enter, and because the ground is stable after the landfill, it is becoming popular as a waste disposal method. It is also under consideration to use it effectively.

[0004] The solidified waste is obtained by compressing and solidifying incombustibles or the like into a block shape and packing and packing the outside with a sheet or a wire mesh, or similarly, compressing and solidifying into a block shape with a concrete block processing. There are things. The former can be easily packed in a short time and is lightweight,
The latter is better as a ground reinforcement.

[0005]

However, the solidified waste has a property that it is difficult for rainwater or the like to penetrate. However, the solidified waste that is disposed of for a long period of time by landfill, especially the solid waste packaged by the wire mesh or the like. If waste is exposed to rainwater in a landfill state for a long period of time, or if it is exposed to rainwater before it is landfilled in a landfill at the disposal site, If sewage or the like is discharged from the environment, there is a concern that it will adversely affect the environment such as soil pollution. In general, waste disposal sites are often set up in locations away from residential areas, especially in mountainous areas where roads are not fully equipped, so large trucks and other vehicles are used to transport solidified waste to the disposal sites. There is a problem that is difficult to use.

The present invention has been made in view of the above-mentioned problems, and can prevent soil contamination even if sewage is generated, and can easily transport solidified waste to a disposal site. It is intended to provide a waste disposal site and a waste disposal method.

Also, since the mounting part roof is formed of a flexible material having waterproofness,
When air is blown into the space between the receiver roof and the waste receiver by the blowing means, the space is pressurized and the receiver roof expands to form a wide work space. Furthermore, since the mounting part roof is formed of a waterproof material, it is possible to prevent the infiltration of rainwater during the loading of the solidified waste and the mounting work. In the waste disposal method according to claim 2 , the solid waste can be transported even in a place where road facilities or the like are not completely installed by installing the waste transport means. The solidified waste is not exposed to rainwater during these operations because it is carried into and placed on the waste storage section after the roof installation process. In addition, the inner surface of the waste mounting part is covered with a water-impervious sheet, and the solidified waste to be mounted is further covered with a water-impervious sheet in the mounting part water-shielding step so that rainwater and the like do not enter from outside. In addition, after the wastewater is treated so that it does not seep to the outside even if it is discharged, the waste storage part is reclaimed in the storage part landfilling process, and the mounting part roof is removed in the roof removal process and flattened. Form a ruins.
