MANHOLE BARREL FRAME SUPPORT DEVICE
To provide a manhole barrel frame support device allowing efficiency of manhole barrel frame removal work to be improved by eliminating replacement of members for receiving reaction force when pulling-out a pavement block.SOLUTION: A manhole barrel frame support device 1 comprises: a nail 71 moveable in a radial direction of a manhole barrel frame and capable of lifting up the manhole frame through being inserted under the manhole barrel frame; a pulling-out cylinder 63 vertically moving the nail 71; and a reaction force plate 61 arranged on the pulling-out cylinder 63 and having a ground plane F1 contactable on the ground at a position further outside in the radial direction than the pulling-out cylinder 63. The ground plane F1 can move relating to the pulling-out cylinder 63 so as to change a distance from the pulling-out cylinder 63.SELECTED DRAWING: Figure 1
【課題】舗装塊を引き抜く際の反力をとるための部材の交換を不要とすることで、マンホール胴枠撤去作業の効率化を図ることができるマンホール胴枠支持装置を提供する。【解決手段】マンホール胴枠支持装置１は、マンホール胴枠の径方向に進退可能で、マンホール胴枠の下に挿入されてマンホール胴枠を持ち上げることが可能な爪７１と、爪７１を上下動させる引抜シリンダ６３と、引抜シリンダ６３に設けられ、引抜シリンダ６３よりも径方向外側の位置で地面と接触可能な接地面Ｆ１を有する反力板６１を備える。接地面Ｆ１は、引抜シリンダ６３からの距離が変わるように、引抜シリンダ６３に対して移動可能である。【選択図】図１
