Although the illustrated figure shows a jet nozzle as an embodiment, any power unit capable of transmitting propulsion force may be used.

The nozzle unit 200 will be described in more detail with reference to FIGS. 4A and 4B.

4A is a front view of the water and sewage pipe maintenance apparatus according to the present invention, which is a view of the nozzle unit 200, and FIG. 4B is a cross-sectional view taken along line AA ′ of FIG. 2.

The fluid is supplied to the nozzle unit 200 through the connection pipe 340. The connecting tube 340 and the main body 310, in particular, the insertion tube 211 inserted into the main body 310 are connected to be fluid sealed using the sealing material 212.
