In general, the waste landfill facility 10 for landfilling waste 17 is used in the mountains or valleys, or a pit is used. All of the waste landfill facilities 10 have slopes 12 formed from the bottom surface. do. Therefore, the waste 17 is stacked in the waste landfill facility 10, and then covered with a waste to fill the waste 17.

However, in such a case, rainwater permeates, and the waste 17 itself contains moisture, and the leachate contaminated with heavy metals, chemical components, etc. flows into the stacked waste 17, which is inclined surface 12. It penetrates through and contaminates soil and groundwater.

In addition, in the case of the waste landfill facility 10, the ventilation is not smooth, so that the gas formed in the stacked waste 17 is not easily discharged, and oxygen is not smoothly supplied from the outside. Therefore, as soon as the aerobic or semi-aerobic waste landfill facility 10 is not realized, it is difficult to stabilize the waste landfill facility 10.

For this reason, the inclined surface 12 of the waste landfill facility 10 is constructed as follows for the effect of blocking and aeration of the leachate.

When the base 11 is earth and sand, the nonwoven fabric 13, the civil synthetic resin clay (14, bentonite mat), and the degree sheet (15, High Density Polyethylene sheet; HDPE sheet) from the base 11 , Non-woven fabric (16, geocomposite, geonet, geotextile) after construction, the sand bag 45 filled with leachate drainage material 40, such as sand, waste foundry sand, our company, stacked to a height of 30 cm or more, or waste tires Waste (17) is buried after the sand (20) is filled with sand, waste foundry sand or waste sand (40).

When the base 11 is a rock, soil cement or spun concrete from the base 11, nonwoven 13, civil synthetic resin clay 14, bentonite mat, order sheet 15, nonwoven 16, geocomposite, After constructing the geonet, geotextile), the sand bag 45 is filled with leachate drainage material 40, such as sand, waste foundry sand, our company, stacked to a height of 30cm or more, or for the waste tire 20 to the leachate drainage After the material 40 is filled up, the waste 17 is buried.

The leachate drainage material 40 is filled, and the sandbag and waste tire 20 woven from polyethylene filter and discharge the leachate contaminated with heavy metals and chemicals, and ensure breathability to the inside of the waste 17. It is prescribed | regulated that construction may be carried out so that the gas which generate | occur | produces may be discharge | emitted smoothly, oxygen may be supplied smoothly from the exterior, it will be in an aerobic or semi-aerobic state, and the order sheet 15 is protected.

By the way, in the case of the sandbag 45, there is a lack of the coupling means of each sandbag 45, when stacked on the inclined surface 12, there is a problem that collapses well, the top of the order sheet 15 in a steep slope During installation, it is not easy to install because it slides well downwards.

In the above example, when the waste tire 20 is installed on the non-woven fabric 16 on the inclined surface 12, that is, on the upper surface of the order sheet 15, the waste tire 20 in which a plurality of through-holes 21 are drilled in the ground surface is formed. After arranging the top of the inclined surface 12 of the waste landfill facility 10, after binding to each other to the rope 30 through the through-hole 21, the top of the rope 30 to the fixed stake 18 to the outside After binding and supporting with), after filling the leachate drainage material 40 between and between the waste tires 20, the waste 17 is laminated.

In the case of the waste tire 20, there is a lack of coupling means between each other, even if stacked along the inclined surface 12 from the bottom surface is easy to fall apart, after binding to the rope (30), respectively, the pile 18 fixed to the outside ) Is hanging.

However, in this case, since the weight of the waste tire 20 is large, when the waste 17 is stacked, the rope 30 which is bound to the outer pile 18 or the rope 30 which is between the phases of the waste tire 20 is cut off. As the waste tire 20 descends together with the settled waste 17, the order sheet 15 is torn.

Of course, the order sheet 15 is constructed below the nonwoven fabric 16, but the nonwoven fabric 16 is lowered together with the waste tire 20, or the nonwoven fabric 16 is torn and the order sheet 15 is easily damaged.

In addition, after the waste tire 20 is installed on the inclined surface 12 of the waste landfill facility 10, filling the leachate drainage material 40, such as sand, waste foundry sand or waste sand, between and inside the waste tire 20. Even if it rains, the leachate drainage material 40 has a problem that all flows down with rainwater and is lost.

In addition, the drainage and aeration efficiency is substantially poor because drainage and aeration are possible through a limited number of apertures 21 drilled to the ground plane of the waste tire 20.

And to bind the waste tires 20 listed on the wide slopes 12 to the rope 30 one by one is cumbersome, hard work requires a lot of construction time and labor.

Therefore, the present invention is designed to solve the problems as described above, the mutual coupling means are simple, efficiently protect the order sheet, drainage and aeration through the entire surface is high drainage and aeration efficiency, and is filled inside It is an object of the present invention to provide a sand block for protecting a seat sheet of a waste landfill facility that is not likely to lose sand, waste foundry sand, or leachate drainage materials such as waste sand.
