UNDERGROUND PIPE PROTECTION BODY AND UNDERGROUND PIPE PROTECTION METHOD
To provide an underground pipe protection body that can suppress abrupt increase of a load applied to an underground pipe and suppress subsidence by being installed on an upper surface side of the underground pipe embedded under the ground, and provide an underground pipe protection method.SOLUTION: An underground pipe protection body 1 is arranged above an underground pipe 2, and comprises: a plate-shaped concrete skeleton 3 installed horizontally; a plurality of columnar piles 4 arranged while sandwiching the underground pipe 2 facing in a vertical direction; and a plate-shaped buffer 5 sandwiched between the plurality of piles 4 and arranged horizontally between a lower surface 3a of the concrete skeleton 3 and the underground pipe 2. Further, an upper end 4a of the pile 4 is joined to and integrated with the lower surface 3a of the concrete skeleton 3.SELECTED DRAWING: Figure 1
【課題】地中に埋設される埋設管の上面側に設置することにより、埋設管が受ける荷重の急激な増加を抑制し、かつ沈下を抑制することができる埋設管防護体及び埋設管防護工法を提供することにある。【解決手段】埋設管防護体１は埋設管２の上方に配置され、水平に設置された板状のコンクリート躯体３と、鉛直方向を向いた埋設管２を挟みながら配置された複数の円柱状の杭４と、この複数の杭４の間に挟まれ、かつコンクリート躯体３の下面３aと埋設管２の間に水平に置かれた板状の緩衝体５とからなる。さらに、杭４の上端４ａはコンクリート躯体３の下面３ａに接合され、一体化されている。【選択図】図１
