Rainwater that falls on the water-impervious sheet 12 flows into the surface water vertical drain pipe 51 and is guided to the surface water drain pipe 5 and stored in the disaster prevention adjustment pond or the like.

  In parallel with the landfill process in the third landfill pit 4C, as shown in FIG. 5, the partition dam 30 and the earth dam 20 are built on the treated landfill pits 4A and 4B, and the first tier in the second stage. Landfill pit 40A is created. Then, after performing the in-pit processing of the third landfill pit 4C at the first stage, the roof 1 is lifted by a lifting machine and moved to the first landfill pit 40A at the second stage as shown in FIG. At this time, the rain that has fallen on the first landfill pit 40A in the second stage is covered with the covering of the second landfill pit 4B in the first stage by the roof 1 so as to cover the entire first landfill pit 40A in the second stage. It is installed so as to flow into the cover of the third landfill pit 4C. In addition to the waste landfill process in the second stage first landfill pit 40A, a section is placed on the processed first stage landfill pit located beside the second stage first landfill pit 40A. The dam 31 and the earth dam 21 are built, and the second-stage second landfill pit 40B and the second-stage third landfill pit 40C are formed. Then, after the in-pit processing of the second stage first landfill pit 40A, as shown in FIG. 7, the roof 1 is lifted by a lifting machine and moved to the second stage second landfill pit 40B. In addition, the rain that has fallen on the second landfill pit 40B covers the entire second landfill pit 40B, and the roof 1 covers the cover of the second stage first landfill pit 40A and the first stage third landfill pit 4C. Install so that it flows into the cover. After performing the in-pit processing of the second landfill pit 40B, as shown in FIG. 8, the roof 1 is moved to the second landfill pit 40C, and the in-pit processing of the third landfill pit 40C is performed. At that time, the rain that has fallen on the second landfill pit 40C is covered by the roof 1 so as to cover the entire third landfill pit 40C, and the cover of the second stage first landfill pit 40A and the first stage third landfill pit. Install so as to flow into the cover of 4C. At this time, the earth dam 22 and the section dam 32 are built on the first landfill pit 40A and the second landfill pit 40B in the second stage after the processing, and further, after the in-pit processing of the third landfill pit 40C, A section dam 33 extending to the section dam 32 is built on the treated third landfill pit 40C to form a section dam 34, and a third stage first landfill pit 400A is formed. Then, as shown in FIG. 9, the roof 1 is moved from the third landfill pit 40C in the second stage to the first landfill pit 400A in the third stage, and the in-pit processing of the first landfill pit 400A in the third stage is performed. At that time, the rain that has fallen on the first landfill pit 400A is covered with the cover 1 of the second landfill pit 40B on the second stage and the third landfill pit so as to cover the entire first landfill pit 400A of the third stage. Install so as to flow into the cover of 40C.
