水抜きパイプ及びその施工方法
Document Type and Number:
Japanese Patent JP7121611
Kind Code:
B2
Abstract:
To provide a draining pipe being buried in the ground with a slope face, which is excellent in drainage performance and in strength, which is easily produced, and which prevents inflow of sediment.SOLUTION: A draining pipe 1 comprises a cylindrical part 2 and water guiding material 3 filled in the cylindrical part 2. The cylindrical part 2 comprises: a steel spiral member 5 spirally wound around an axis line, and including parts adjacent to each other in a direction of the axis line, are spaced apart from each other; and a plurality of steel long members 4 placed parallel to the axis line and at an interval between each other and fixed onto an outer peripheral side of the spiral member 5. The cylindrical part 2 has high drainage performance due to being formed in a grid shape, and high strength due to being made of steel.SELECTED DRAWING: Figure 1
