摘要： PROBLEM TO BE SOLVED: To improve the function by covering the ground part of a plastic sheet having one lateral side part buried in the ground with earth and sand, and covering the surface with a plastic cover. SOLUTION: In construction of a levee 1, one lateral side part of a strip plastic sheet 2 is inserted to an insert groove longitudinally provided in a levee setting part followed by back filling and fixed by rolling compaction. A form is thin arranged on both sides of the ground protruding part of the sheet 2, and earth and sand, or earth and sand including cement or a soil hardener is filled in the inner part to form a levee body part 3. After cover insert grooves are formed on both the foot parts of the body part 3, the form is removed, the body part 3 is covered with a plastic cover 4, and both the edges 4a thereof are inserted to the cover insert grooves followed by back filling and rolling compaction to fix the cover 4. According to this, since penetration of water for irrigation and boring by small animals can be surely prevented, and the strength is ensured by the levee body part, the plastic cover can be thinned to significantly reduce the cost, and the construction can be also facilitated.
