Abstract

PURPOSE: To accomplish the reuse of agricultural films used by melting thereof to form a mass of up to 3W25mm in diameter for water impervious packing material.
CONSTITUTION: A ditch 25W30cm wide and 80W100cm deep is dug into a excessively water-soaked farm field (including those previously used for a paddy field). Then, drain blocks 1 composed of a foamed polystylene or the like each having drain grooves 2, 2... formed are successively laid on the bottom thereof wrapped with a plastic net 30. Then, on both the sides and the top, the drain block 1 is packed at a thickness of 5W10cm with a water impervious packing material 10. Thereafter, soil 40 is backfilled 50W70cm into upper portion of the ditch 20 to form an underdrainage. The water impervious packing material 10 employs an irregularly-shaped mass of up to 3W25mm in diameter made up of agricultural films sliced and melted for reuse.
