Document Type and Number:
Japanese Patent JP6522319
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To provide a concrete pile which increases efficiency in heat exchange with under the ground, and can connect an embedded heat exchange pipe to pipes above the ground even when the pile stops at a high position.SOLUTION: A U-shaped heat exchange pipe comprising a supply pipe 21, a return pipe 23 and a folded pipe 25 is embedded in a concrete pile body 1 with an H-shaped cross section so as to form a concrete pile 40. An opening edge 22 of the supply pipe 21 and an opening edge 24 of the return pipe 23 are located an upper end of the pile body 1 and covered with sheath pipes 31. The supply pipe 21 and the return pipe 23 are arranged near outer edges 5, 5 of the pile body 1. Even if the concrete pile 40 stops at a high position upon piling, an upper end part 1A is cut so as to remove the sheath pipes 31 and expose the opening edge 22 of the supply pipe 21 and the opening edge 24 of the return pipe 23 thereby allowing connection with liquid delivery pipes 44, 45 above the ground.SELECTED DRAWING: Figure 1
