SURFACE MATERIAL BLOCK UNDERSIDE FLUID GUIDE PIPE INSTALLATION

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 【課題】自然石の舗装表層材ブロックの下面に設置された砕石または骨材層の空隙にＣＡモルタルまたは流動性のある部材を効果的に浸透させる工法を提供する。【解決手段】ブロック１２の下面に両端に開口をもつ筒８を敷いて、筒８の入口から奥に向かってＣＡモルタルまたは流動性部材を流し込む。筒８の途中に孔９を設けることで、筒に沿って四方にＣＡモルタルまたは流動性部材を浸透させることができる。孔９より大きい砕石１０を孔９の周囲を囲むように一列以上敷き並べ、孔９より小さい砕石１１の量を抑制して、ＣＡモルタルまたは流動性部材が孔９を効率よく流れ出ることができる。【選択図】図３
