the driving piece drives the high-pressure water pump to work, a water source enters the high-pressure water pump from the water pipe, the high-pressure water pump pressurizes water to form two strands of high-pressure water, and one strand of high-pressure water is sprayed out from the spray head after passing through one pipe body on the composite pipe; the other strand of high-pressure water sequentially passes through the other pipe body on the composite pipe and the fluid inlet on the jet pump and then enters the diffusion pipe on the jet pump to form high-pressure fluid;
and starting the negative pressure piece, wherein a water pumping port on the negative pressure piece is connected with a diffusion pipe on the jet pump through a first pipe body on the composite pipe, so that the blockage in the underground pipeline to be dredged is pumped away from a fifth water outlet on the negative pressure piece after sequentially passing through a throat pipe on the jet pump, the diffusion pipe on the jet pump and the first pipe body.
