METHOD FOR INSTALLING UNDERGROUND HEAT EXCHANGER ON EXISTING PILE
To provide a method for installing an underground heat exchanger on an existing pile that is not affected by a step of pile work without performing EF joint operations, and that secures stable quality and safety of operators.SOLUTION: An underground heat exchanger 15 is hung from a crane 55 using a belt sling 57 to be connected to a hanging tool of a pile head inner lid 1. The underground heat exchanger 15 and the pile head inner lid 1 are integrated, and can therefore be inserted into an existing pile 50 in that condition. A metal weight 40 made of C-shaped steel is fixed on the lower end of each U-shaped tube 16 for underground heat exchange. The weight 40 does not age and is disposed to keep the U-shaped tube 16 for underground heat exchange in a vertical position.SELECTED DRAWING: Figure 4
【課題】既製杭への地中熱交換器設置工法において、杭工事の工程に左右されず、ＥＦ継手作業を行うことなく、安定した品質を確保し、かつ作業員の安全も確保する。【解決手段】地中熱交換器１５をクレーン５５で杭頭内蓋１の吊り具にベルトスリング５７で吊り下げる。地中熱交換器１５は杭頭内蓋１と一体であるから、そのまま既製杭５０内に挿入するだけで良い。各地中熱交換用Ｕチューブ１６の下端部に金属製のＣ型鋼で作られたウェイト４０が固定されている。ウェイト４０は、経年変化することなく、地中熱交換用Ｕチューブ１６が鉛直姿勢に保つように配置したものである。【選択図】図４
