To provide a manhole inside washing device that allows easy and reliable vertical moving of wash water injection body with a simple constitution and arbitrary turning of a washing nozzle at the center in a manhole.SOLUTION: A manhole inside washing device includes: a column 3 to be inserted into a manhole 2; a column upper part supporting pedestal 5 arranged in a road surface opening part 4 of the manhole 2 and supporting the column 3 so as to rotatable in a substantially center of the manhole 2; a column lower end supporting pedestal 7 arranged in a bottom part 6 in the manhole 2 and rotatably receiving a lower end of the column 3 in the center in the manhole 2; a wash water injection body 9 supported to be movable in a vertical direction by the column 3, and receiving supply of high pressure wash water from a high pressure wash water hose 8 and injecting the wash water toward an inner surface of the manhole 2; wash water injection body moving means 10 for vertically moving the wash water injection body 9 along the column 3; and rotary means 11 for rotating the column 3.SELECTED DRAWING: Figure 1
【課題】人孔（マンホール）内のセンターで洗浄水噴射体の上下移動を簡単な構成で容易にかつ確実に行えるようにするとともに、洗浄ノズルの旋回を任意に行えるようにした人孔内部洗浄装置を提供する。【解決手段】人孔２内に挿入される支柱３と、人孔２の路面開口部４に配置され、支柱３を人孔２の概ね中心で回転可能に支持する支柱上部支持台座５と、人孔２内の底部６に配置され、支柱３の下端を人孔２内のセンターで回転自在に受ける支柱下端支持台座７と、支柱３に上下方向移動可能に支持され、高圧洗浄水ホース８から高圧の洗浄水の供給を受けて人孔２の内面に向かって洗浄水を噴射する洗浄水噴射体９と、洗浄水噴射体９を支柱３に沿って上下移動させる洗浄水噴射体移動手段１０と、支柱３を回転させる回転手段１１とを備えてなる。【選択図】図１
