SIDE DITCH STRUCTURE FOR WATER PERMEABILITY PAVED ROAD, SIDE DITCH LID FOR WATER PERMEABILITY PAVED ROAD, ITS SIDE DITCH WORK EXECUTION METHOD, AND WATER PERMEABILITY PAVED ROAD

摘要

PROBLEM TO BE SOLVED: To provide a side ditch structure for a water permeability paved road capable of ensuring smooth fluidity of rainwater to improve water draining capability and being suitable for cast-in-place concrete work execution as well as application of a side ditch body of a concrete secondary product.;SOLUTION: This side ditch structure is provided with the side ditch body 2 and a side ditch lid 3. An upper end face 26 of a side wall 23 on a paved road side of the side ditch body is formed in such a way that it is positioned at substantially the same position as a boundary 13 of a substrate layer 11 and a water permeability surface layer 12 or below the boundary. A water passing port 31 passing through a rear surface from an upper face is formed on the side ditch lid. The whole upper face of the side ditch lid is covered with a water permeability surface layer 4 on a side ditch side continuous with the water permeability surface layer of the water permeability paved road integrally by simultaneous construction. Rainwater permeates the water permeability surface layer on the side ditch side to make it flow into the inside of the side ditch body through the water passing port of the side ditch lid.;COPYRIGHT: (C)2005,JPO&NCIPI
