Anti-adhesion drill rod for spiral pile hammer
The invention discloses an anti-adhesion drill rod for a spiral pile hammer. The anti-adhesion drill rod for the spiral pile hammer comprises a drill rod body, and spiral blades are arranged on the drill rod body. The anti-adhesion drill rod for the spiral pile hammer is characterized in that a hollow inner cavity is formed in the drill rod body, and a high-pressure water spraying cavity is formed in the hollow inner cavity; a water outlet which is communicated with the high-pressure water spraying cavity is formed in the drill rod body, and a one-way valve enabling water to flow in one direction is arranged in the water outlet. According to the technical scheme, it is guaranteed that the drill rod has high pressure resistance, and soil can be prevented from adhering to the drill rod.
