SOLUTION: An excavation hole 4 is formed in the seashore by an excavator 3. The water permeable drain pipe 6 is mainly composed of cylindrical woven fabric 10 having a self-shape keeping property by using thread having bending repulsion in a part of at least the weft, and is connected to a tip part of an excavation rod 5 of the excavator 3. The drain pipe 6 connected to the excavation rod 5 is pulled in the excavation hole 4 by extracting the excavation rod 5 from the excavation hole 4. Thus, the laying work of the drain pipe 6 is facilitated, and the drain pipe 6 can also be laid in the seashore without impairing the scenery as practical as possible. COPYRIGHT: (C)2005,JPO&NCIPI
