Title:
PAVEMENT FACE FORMING BLOCK AND PERMEABLE PAVEMENT STRUCTURE
Document Type and Number:
Japanese Patent JP3628521
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To heighten water retaining capacity and to safely return rainwater to the underground without lowering the support force of a roadbed and without providing a permeable pavement face forming block with a water cut-off layer or a water guide path.
SOLUTION: A pavement face forming block is provided with a permeable pavement plate 1; a funnel-shaped receiving frame 2 for supporting the outer periphery of the pavement plate 1; and a water flow pipe 6 connected to a water collecting part. The upper end opening of the conduit pipe 6 is protruded upward from the lower end of the water collecting part 4 to form a water storage pocket. The lower part of the water flow pipe 6 is provided with a large number of radial small holes 9, and natural crushed stones or activated charcoal can be filled in the space 11 of the water collecting part 4 of the receiving frame 2. This water flow pipe 6 of the pavement face forming block pierces a support bed for supporting the pavement face and reaches a bed at the depth of the lower end opening or small holes 9 not impairing support force by the increase of water content. Rainwater having passed the permeable pavement plate 1 is collected into the water collecting part 4, guided to the safe bed even with the increase of water content and drained into soil. Since part of rainwater is stored in the water storage pocket of the receiving frame 2, earth temperature rise and dryness can be mitigated by the evaporation of this rainwater to impart water retaining capacity and rainwater purifying capacity to the block.
