<p>PROBLEM TO BE SOLVED: To provide a waste shielding method and waste shielding structure for such a waste disposition facility which presumes even the case to the failure of an impervious layer and assures the safety of the facility in such a case. SOLUTION: The bottom and wall part of the waste disposition plant 11 for disposing waste is formed as the impervious layer 17. This disposition plant 11 provided with an inside water level observation well 12 which allows the measurement of the level of the water stagnating in the waste disposition plant 11 and is provided with a water lifting pipe 13 capable of lifting this water and a water lifting pump 14 connected to this water lifting pipe 13. On the other hand, the waste disposition plant 11 is provided with a ground water level observation well 16 which allows the measurement of the ground water level of a subsoil 15 around the waste disposition plant 11. The water level in the inside water level observation well 12 is set lower than the water level in this ground water level observation well 16. In case of the rupture of the impervious layer 17, the ground water flowing in from the ambient subsoil 15 is pumped up from the water lifting pipe 13 by the water lifting pump 14, by which the waste is shielded from the circumferential subsoil 15.</p> |
