METHOD OF CONSTRUCTING WATER PERMEABLE PAVEMENT, AND WATER PERMEABLE TILE

摘要

PROBLEM TO BE SOLVED: To provide a method of constructing a water permeable pavement with high adhesion and high water permeability and a water permeable tile suitable therefor. ;SOLUTION: A sub base 2 consisting of crushed stone is formed on a subgrade 1. A water permeable concrete layer 3 is formed on the sub base 2. A water permeable tile 5 is adhered onto the water permeable concrete layer 3 in dot or mesh form. According to this, high adhesion and water permeability can be ensured. A water collecting pipe 6 is arranged in the water permeable concrete layer 3 to purify and collect rainwater. The collected water is guided to a storage pit 11 through a storage tank. The storage pit 11 is provided with a storage pump 13 to circulate and reuse the water. As the water permeable tile 5, shirasu is used in addition to conventional silica rock, crushed stone, or crushed matter of tile, pottery, or glass. Thus, a lightweight and highly water permeable one can be provided at a low cost.;COPYRIGHT: (C)1999,JPO
