後、放流される。2. Description of the Related Art In a final disposal site of a pipe buried type waste, a connection structure shown in FIG. In FIG. 1, reference numeral 1 denotes an embankment for storage, and 2 denotes an external drainage pipe formed of a non-perforated pipe pierced through the inside and outside of the embankment 1. In the disposal site,
The end of the drainage pipe 2 on the side where the leachate is taken in is connected to the leachate collection and drainage pipe 3 formed of a perforated pipe, and the leachate taken into the collection and drainage pipe 3 is discharged out of the treatment plant through the drainage pipe 2. After being detoxified by a water treatment facility (not shown), the water is discharged.

In order to prevent leakage of seepage water at this penetration position,
Conventionally, the water-impervious sheet 4 is wound around the drain pipe 2 and the periphery thereof is fixed with a welding band 5 or the like.
The water stop was secured. In the drawing, reference numeral 6 denotes a water-permeable member such as crushed stone or gravel that is scattered on the bottom surface of the disposal site and covers the periphery of the drainage pipe 3, and waste (not shown) is sequentially deposited on the upper part.

Due to the workability of winding the welding band 5, the penetration position of the drain pipe 2 cannot be located at the lowest part of the embankment 1, and is located at a position slightly above the bottom surface in the disposal site. As a result, the piping position of the collection / drainage pipe 3 also had to be located slightly above the bottom surface. Accordingly, with such a structure, the lowest water level LWL is located below the drainage pipe 3,
The exuded water became accumulated water and stayed between the water-permeable members 6, and could not be completely drained.
