Document Type and Number:
Japanese Patent JP2765324
Kind Code:
B2
Abstract:
PURPOSE: To provide sufficient drainage function without using a sand mat.
CONSTITUTION: A drainage mat 1 is formed in an integrated manner so that a rectangular top plate 2 and a bottom plate 3 may be arranged to be alternately located in the vertical direction by four supporting legs 4, and a 3-dimensional checkerwise continuous pattern is formed as a whole, and a hollow configuration is kept with a thickness according to the height of the supporting legs 4. An nonwoven cloth 5 is laid on the position on a poor subsoil (E) where banking is scheduled to be executed, and the drainage mat 1 is laid upon the upper surface. Then, the nonwoven cloth 5 is set on this drainage mat l to cover both sides in the width direction. Banking earth 6 is filled on the drainage mat 1. The surface pressure due to the earth pressure of the banking earth 6 is applied to the drainage mat 1, but the thickness is kept constant according to the pressure proof strength of the respective supporting legs 4 and the hollow configuration is maintained.
