Pipe communicating device

The invention discloses a pipe dredging device, and relates to the technical field of cable pipe gallery maintenance, the pipe dredging device comprises a device main body and a spiral drill bit, and the spiral drill bit is fixed on the device main body and is used for drilling a pipe dredging hole; the corresponding device body is provided with a plurality of water outlet ends which are evenly distributed around the circumference of the center line of the spiral drill bit and tangent to the track circle line where the water outlet ends are located, the water outlet ends are connected with the water inlet end, and after high-pressure water is input through the water inlet end, the high-pressure water can be sprayed out of the water outlet ends. The device body rotates around the center line of the spiral drill bit under the counter-acting force of the jet water flow, and then the spiral drill bit is driven to rotate. The spiral drill bit is driven to rotate through the counter-acting force of the jet water fl
