Kind Code:
A
Abstract:
To provide a method of effectively infiltrating a CA mortar or a fluid member into voids of a crushed stone or an aggregate layer installed on the underside of a natural stone pavement surface block.SOLUTION: A cylinder 8 having openings at both ends is laid on the underside of a block 12, and a CA mortar or a fluid member is poured from the inlet of the cylinder 8 toward the back. By providing a hole 9 in the middle of the cylinder 8, the CA mortar or the fluid member can be permeated in all directions along the cylinder. One or more rows of crushed stones 10 larger than the hole 9 are laid out so as to surround the circumference of the hole 9. By suppressing the amount of crushed stones 11 smaller than the hole 9, the CA mortar or the fluid member can efficiently flow out of the hole 9.SELECTED DRAWING: Figure 3
