（２１）の壁内の接線側に傾斜されている。That is, the injection nozzle (21) is inclined toward the rear side in the cross-sectional view of FIG. 7, and is inclined toward the tangential side within the wall of the injection nozzle (21) when viewed in plan as shown in FIG. .
そこで、管（２４）の内面を上記の管内洗浄機（Ａ）で
洗浄するに１よ、該管（２４）の一端口より噴射ノズル
（２１）を挿入し、フレキシブルホース（２０）に高圧
水を供給する。Therefore, in order to clean the inner surface of the pipe (24) with the above-mentioned pipe washer (A), the injection nozzle (21) is inserted from one end of the pipe (24) and high-pressure water is inserted into the flexible hose (20). supply.
該高圧水は噴射ノズル（２１）に供給され噴射孔（２３
）から速い勢いで管内面に噴射し衝撃を与え錆（２５）
や付着した汚濁、藻などを一挙に剥奪する構成である。The high pressure water is supplied to the injection nozzle (21) and the injection hole (23
) is sprayed onto the inner surface of the pipe with high force, causing a shock and rusting (25)
It has a structure that removes adhered pollution, algae, etc. all at once.
