<P>PROBLEM TO BE SOLVED: To provide a structure sheet for waste water that holds water permeability pipe materials during construction, and can reduce time and effort in manufacturing. <P>SOLUTION: In a structure sheet for waste water, a plurality of parallel water permeability pipes 3 are sandwiched by sheet materials 1 and 2 from both sides. At least one of the sheet materials 1 and 2 is fixed to the water permeability pipes 3, and at least one of the sheet materials 1 and 2 is a water permeable sheet. Furthermore, the first sheet material 1, one of the sheet materials, the second sheet material 2, the other one of the sheet materials, and the water permeability pipe material 3 are fixed under any of following conditions: 1) the first sheet material 1 and the water permeability pipe 3 are fixed, and the second sheet material 2 and the water permeability pipe 3 are fixed; 2) the first sheet material 1 and the water permeability pipe 3 are fixed, and the first sheet material 1 and the second sheet material 2 are fixed; and 3) the second sheet material 2 and the water permeability pipe 3 are fixed, and the first sheet material 1 and the second sheet material 2 are fixed. <P>COPYRIGHT: (C)2013,JPO&INPIT |
