<p><P>PROBLEM TO BE SOLVED: To provide an inexpensive interlocking block superior in safety and workability. <P>SOLUTION: Since raw materials are crushed stones having the particle size of 2.5 to 10 mm and cement, a block body 11 has water permeability, and a rubber plate 12 composed of a rubber chip is water permeable. Since an adhesive 14-unapplied water permeable area 15 is secured on a contact plane of both, water permeability as a whole of the interlocking block 13 is not impaired. The safety can be secured by providing resiliency and cushioning performance by the rubber plate 12 adhered to an upper surface of the block body 11, to thereby provide a utility value such as laying on a public square such as a park and a sidewalk requiring drainage performance. <P>COPYRIGHT: (C)2005,JPO&NCIPI</p> |
