GROUND SURFACE TEMPERATURE CONTROL DEVICE

PROBLEM TO BE SOLVED: To alleviate a burden of work for bending a bent pipe part of a temperature control pipe for a ground surface temperature control device.SOLUTION: A temperature control pipe 20 of a ground surface temperature control device 1 is buried under a ground surface 9d. A pair of straight pipe parts 24 and 24 of the temperature control pipe 20 are linearly extended along the ground surface 9d. The straight pipe parts 24 and 24 are joined together via a bent pipe part 22. A connecting pipe part 25 is provided between the straight pipe part 24 and the bent pipe 22. The connecting pipe part 25 is inclined to the opposite side of the other straight pipe part toward the bent pipe part 22 from the straight pipe part 24.SELECTED DRAWING: Figure 6 【課題】地表面温調装置における温調管の曲管部の曲げ作業の負担を軽減する。【解決手段】地表面温調装置１の温調管２０を地表面９ｄ下に埋設する。温調管２０の一対の直管部２４，２４を地表面９ｄに沿ってそれぞれ直線状に延ばす。これら直管部２４，２４どうしを曲管部２２で連ねる。直管部２４と曲管部２２との間に接続管部２５を設ける。この接続管部２５を、直管部２４から曲管部２２へ向かうにしたがって他方の直管部とは反対側へ傾ける。【選択図】図６
