摘要： PURPOSE:To shut off underground seepage water, by a method wherein a drainage pipe, installed to the bottom of a drainage ditch, is covered with a permeable covering substance, a permeable layer is formed throughout the total surface of the side wall, such as embarkment side, levee side of the drainage ditch, and after the permeable layer is covered with an impermeable film, the drainage ditch is back filled. CONSTITUTION:A drainage pipe 2 is installed on the bottom of a drainage ditch 1 excavated under the cultivating land B side of levee C, and the drainage pipe 2 is covered with a permeable covering substance 3 such as foaming synthetic resin, straw, etc. A permeable layer 4, similar to the covering substance 3, is laid throughout the total surface of the side wall on the levee C side of the drainage ditch 1, and after the surface of the permeable layer 4 is covered with an impermeable film 5 consisting of a plate material made of soft synthetic resin or rubber, the drainage ditch 1 is back filled. This enables seepage water to be guided to the drainage pipe 1 by means of the permeable layer 4 in a condition in which penetration of underground seepage water, penetrating through the levee C from river or lake and ozzing out to a face C1 of slope, into a cultivated land B, is shut off by means of the impermeable film 5.
