PROTECTIVE STRUCTURE OF IMPERVIOUS SHEET
Document Type and Number:
Japanese Patent JP3123404
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To make it possible to provide a protective structure for protecting the impervious sheets to be laid in a waste disposition plant with a function to prevent water leakage in addition to a function to protect the impervious sheets by covering the surfaces of the impervious sheets while temporally tacking the top ends of plural sheet plates, thereby continuously disposing these sheet plates like roof tiles.
SOLUTION: The waste disposition plant 10 is constituted by excavating and forming, for example, a mountainous area, etc., to a recessed shape and is subjected to impervious work to prevent the sewage leeching from wastes 30 discarded therein to the surrounding subsurfaces by laying the impervious sheets 11 on the base of the recessed part. The protective structure 12 of the impervious sheets 11 is designed to protect the impervious sheets 11 and is constituted by superposing and arranging the bottom end parts 16 of the sheet plates 14 on the upstream side in the inclination direction on the top end parts 17 of the sheet plates 14 on the downstream side in the inclination direction in the connecting parts 15 in the inclination direction of the plural sheet plates 14. The sheet plates are continuously dispersed like roof tiles by covering the surfaces of the impervious sheets 11 while the respective top ends 17 are tack welded to the impervious sheets 11.
