| description | To provide an underground radar for a shield machine that can more reliably detect an obstacle (for example, H-steel) expanding in various directions on a front surface in front of a shield machine travel direction even when an antenna of an underground radar device attached to an arm rotates in a circumferential direction around a rotational center axis of a rotary cutter in accordance with the circumferential rotation of the arm of the rotary cutter of the shield machine around the rotational center axis.SOLUTION: A underground radar for a shield machine is configured such that an underground radar antenna is arranged on arms 1 to 8 of a rotary cutter radially extending from a rotational center axis on the front of the shield machine, where at least one of the plurality of arms 1 to 8 is provided with the plurality of antennas 10 to 13 in the direction in which the arm extends.SELECTED DRAWING: Figure 5
【課題】シールドマシンの回転カッターのアームが回転中心軸を中心にして周方向に回転することに応じて当該アームに取り付けられている地中レーダ装置のアンテナが同じく回転カッターの回転中心軸を中心にして周方向に回転することになっても、シールドマシン進行方向前方の前面で種々の方向に伸びて存在している障害物（例えば、Ｈ鋼）をより確実に検出できるシールドマシン用地中レーダ。【解決手段】シールドマシン前面でその回転中心軸から放射状に複数本伸びている回転カッターのアーム１～８に地中レーダのアンテナが配備されているシールドマシン用地中レーダであって、複数本の前記アーム１～８の中の少なくとも１本に、前記アームが伸びる方向に複数個の前記アンテナ１０～１３が配備されているシールドマシン用地中レーダ。【選択図】図５ |
