MANHOLE INNER WALL WASHING APPARATUS
To provide a manhole inner wall washing apparatus not so relatively large and capable of easy cleaning operation of a manhole inner wall.SOLUTION: A manhole inner wall washing apparatus includes: a washing apparatus body 2 in which a disk-like high pressure water spray body 6 jetting high pressure water to an inner wall of manhole from an opening 4 is arranged in a bottomed cylindrical casing 5 including the opening 4 in a state with a gap S provided between the inner wall of the casing 5 and an outer periphery of the high pressure water spray body 6, an air supply port 11 is provided located on a back surface part 6b side of the high pressure water spray body 6 to supply compressed-air between a bottom wall 5a of the casing 5 and a back surface part 6a of the high pressure water spray body 6 on a side wall 5b of the casing 5, and an air/mixed wastewater discharging port 14 is provided located on a front surface part 6b of the high pressure water spray body 6 and discharging, out of the casing 5, mixed wastewater composed of compressed-air supplied into the casing 5, peeled pieces of the inner wall of the manhole peeled by jetted high pressure water and washing processing water; and suspending means 3 suspending the washing apparatus body 2 vertically movably.SELECTED DRAWING: Figure 4
【課題】 比較的装置が大掛かりにならず、また、人孔の内壁の洗浄作業を容易に行えるようにした人孔内壁洗浄装置を得る。【解決手段】 開口部４を有する有底円筒状のケーシング５内に、開口部４から人孔の内壁に向かって高圧水を噴射する円盤状の高圧水噴射体６を、ケーシング５の内壁と高圧水噴射体６の外周囲との間に隙間Ｓを空けた状態で配置し、ケーシング５の側壁５ｂには、高圧水噴射体６の後面部６ｂ側に位置してケーシング５の底壁５ａと高圧水噴射体６の後面部６ａとの間に圧縮空気を供給する空気供給口１１を設けるとともに、高圧水噴射体６の前面部６ｂ側に位置してケーシング５内に供給された圧縮空気と、噴射した高圧水により剥離した人孔の内壁の剥離片と洗浄処理水とからなる混合廃水をケーシング５外へ排出する空気・混合廃水排出口１４を設けた洗浄装置本体２と、洗浄装置本体２を上下動可能に吊下する吊下手段３を備えたことを特徴とする。【選択図】 図４
