To provide a wood pile unit capable of forming a plurality of wood piles into a unit to increase a support force through simple machining and effectively acquiring geothermal energy by utilizing the wood piles formed into the unit.SOLUTION: A wood pile unit 1 formed by bundling a plurality of wood piles used for ground improvement comprises a plurality of individual wood piles 2a, 2b and 2c traversing at angles of less than 90 degrees in the longitudinal direction of the wood piles at tip parts. The individual wood piles 2a, 2b and 2c are bundled with side parts longest in the longitudinal direction of the individual wood piles 2a, 2b and 2c directed toward the center. When necessary, at least three or more individual wood piles 2a, 2b and 2c are bundled in contact with the other adjacent individual wood piles 2a, 2b and 2c to form a gap region in the center part. A hollow heat-exchange pipe is housed in a U shape in the gap region. Opening parts at both ends of the heat-exchange pipe are arranged to be exposed from the upper part of the gap region.SELECTED DRAWING: Figure 2
【課題】簡単な加工で複数の木杭をユニット化して支持力を高めると共に、ユニット化した木杭を利用して効果的に地熱エネルギーを取得する木杭ユニットを提供する。【解決手段】地盤改良に用いられる木杭を複数本束ねた木杭ユニット１であって、先端部分において木杭の長手方向に対して９０度未満の角度で横断された複数の個別木杭２ａ、２ｂ、２ｃを備え、当該個別木杭２ａ、２ｂ、２ｃの長手方向で最長尺となる側面部分を中心に向けて複数の個別木杭２ａ、２ｂ、２ｃが束ねられている。また、必要に応じて、少なくとも３本以上の個別木杭２ａ、２ｂ、２ｃが、隣接する他の個別木杭２ａ、２ｂ、２ｃに接触した状態で束ねられて中心部分に空隙領域を形成しており、当該空隙領域に中空の熱交換パイプがＵ字状に収納され、熱交換パイプの両端の開口部分が空隙領域の上部から露出した状態で配設されている。【選択図】図２
