  As shown in FIG. 1, the final disposal site 10 for waste includes a pit 14 provided on the ground 12 for containing the waste, and a drain pipe 18 disposed on the bottom 16 of the pit. And a covering material 20 disposed on the bottom 16 of the pit 14 and covering the pipe 18. The pit 14 is formed by a concrete structure 26 having a bottom plate 22 and a peripheral wall 24 surrounding the bottom plate.

  When constructing the final disposal site 10, first, a pit 14 is provided on the ground 12, and then, as shown in FIG. 2, a pipe 18 is disposed on the bottom 16 of the pit 14. Cover with 20. As shown in FIG. 3, the tube 18 extends in the horizontal direction, and includes a peripheral wall 28 and a plurality of through holes 30 provided at intervals in the peripheral wall. The tube 18 is a so-called perforated tube. One end of the pipe 18 is in the pit 14, the pipe 18 extends from the pit 14 to the outside of the pit, and the other end of the pipe 18 is connected to a water treatment device (not shown). The pipe 18 is a fume pipe, a synthetic resin pipe, a steel pipe, or the like.

  When the pipe 18 is covered with the covering material 20, as shown in FIG. 4, it is formed in a peripheral wall portion 34 having two regions 32 spaced in the horizontal direction, and each region 32 of the peripheral wall portion, and is opened downward. A frame body 38 having a cutout portion 36 is prepared. In the example shown in FIG. 4, the frame 38 has a rectangular planar shape. The frame body 38 has two opposite end portions 40 spaced in the horizontal direction and two opposite side portions 42 spaced between the end portions. 36 is formed at each end 40.
