GROUND SURFACE TEMPERATURE CONTROL STRUCTURE AND CONSTRUCTION METHOD THEREOF

PROBLEM TO BE SOLVED: To provide a ground surface temperature control structure capable of ensuring satisfactory temperature control effect on the ground surface of a runway in a track and field stadium while preventing from giving discomfort to athletes.SOLUTION: A runway 91 in a track and field stadium 9 includes a temperature control pipe 20 which is disposed on a ground layer 91c containing asphalt concrete under the ground surface. The temperature control pipe 20 is embedded in a filling layer 91b by laying filling layer 91b containing an elastic granular material 91g over the ground layer 91c. The temperature control pipe 20 is covered by an upper part of the filling layer 91b. A surface layer 91a is laid over the filling layer 91b.SELECTED DRAWING: Figure 5 【課題】陸上競技場において走路の地表面に対して十分な温調効果を確保しながら、競技者に違和感を与えるのを防止可能な地表面温調構造を提供する。【解決手段】陸上競技場９の走路９１の地表面下における、アスファルトコンクリートを含む下地層９１ｃ上に温調管２０を配置する。弾力性粒状物９１ｇを含む充填層９１ｂを、下地層９１ｃ上に敷設して、温調管２０を充填層９１ｂ中に埋設するとともに、充填層９１ｂの上側部分を温調管２０の上側に被せる。充填層９１ｂの上に表層９１ａを敷設する。【選択図】図５
