PROBLEM TO BE SOLVED: To obtain excellent drainage capability by a simple method when an artificial lawn is laid on a hardly permeable or impermeable ground.SOLUTION: For example, in constructing an artificial turf structure 1A by laying an artificial lawn 50 on a hardly permeable or impermeable soil-based ground 110, a crushed stone layer 20 is laid on the ground 110, compacted so as to smooth the surface. Thereafter, on the crushed stone layer 20 a drain filter 40 including a drain tube 42 in a fiber sheet base material 41 is arranged as a drainage layer, and an artificial lawn 50 is arranged on the drain filter 40, and granular matters 54 are packed between piles of the artificial lawn 50.SELECTED DRAWING: Figure 3 |
