PUTTING GREEN BUILT STRUCTURE AND BUILDING WORK METHOD

摘要

The present invention relates to a putting green built structure and building work method with which the task of building the putting green is rapid and accurate, there are savings on water, fertiliser and agrochemicals in the upkeep of the putting green, and the task of upkeep is lessened, and which at the same time has the effect of improving the putting quality of the green surface and allowing use immediately after construction. In the present invention, a water-barrier plate is provided on the floor and the wall surfaces of a green area remodelled by excavation and tamping over a predetermined surface area, and, on top thereof, it comprises: a water-drainage layer which is built up to a predetermined height on the floor surface of the green area in a state in which it contains buried water-drainage plates disposed at a suitable spacing matched to the gradient; an underground water-supply pipe which is provided on the water-drainage layer and which connects to the outside of the green area; and a mixed bed soil layer which is built up to a predetermined height on the water-drainage layer in a state in which the underground water-supply pipe is buried inside, and which has lawn grass cultivated on its upper surface and which is formed with a golf-hole cup.
