IRRIGATION CHANNEL-COATING STRUCTURE, AND IRRIGATION CHANNEL-COATING METHOD
Document Type and Number:
Japanese Patent JP2015166539
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide a coating structure and a coating method for an irrigation channel, which are suitable for soft ground thanks to the usage of a corrugated plate that is lighter than concrete, have a smooth surface without protrusions such as bolts and nuts so that grass does not entwine and water can flow down smoothly, and prevent water leakage into the ground thereby exhibiting superior durability.SOLUTION: A plurality of supporting frames 2, which constitute an irrigation channel-coating structure body 1 and are arranged at a bottom face and at both side faces of the irrigation channel, have a bottom-face corrugated steel plate and a side-face corrugated steel plate 4 laid on the supporting frames 2. Surfaces of the corrugated steel plates 3 and 4 are covered with a polyurethane coating material 8 with a thickness for keeping bolts and nuts not to protrude. A durable covering material 9 is placed on the surface of the coating material 8 to form a smooth water-flow face.
