SAFETY MEASURE DEVICE
To provide a safety measure device having a shape not closing a road surface opening part of a manhole, and exhibiting a function even in a state of a part of the opening closed with a lid.SOLUTION: A safety measure device has a support member 10 fixed along an inner peripheral wall lower than the lid of a road surface opening part, and floating bodies 20 in an elevating/lowering manner in relation to the support member 10. A plurality of floating bodies 20 are arranged in the circumferential direction of the road surface opening part with predetermined intervals. Following level rise in the road surface opening part, the floating bodies 20 float up from a lid displaced part.SELECTED DRAWING: Figure 1
【課題】マンホール等の路面開口部を塞がない形状であるとともに、蓋が開口部の一部を塞いだ状態でも機能を発揮できる安全対策装置を提供する。【解決手段】路面開口部の蓋より下方の内周壁に沿って固定される支持部材１０と、支持部材１０に対して昇降可能な浮体２０とを備えている。浮体２０は、路面開口部の周方向に所定間隔をあけて複数配列されている。路面開口部内の水位上昇に伴って、浮体２０が蓋の外れた部分から浮上することを特徴とする。【選択図】図１
