| titleOfInvention | Pile sinking method capable of reducing vibration influence based on phase change |
| abstract | The invention discloses a method for reducing vibration influence on pile sinking based on phase change, which is characterized in that a pile is vertically erected on a foundation soil layer, and the pile, a clamp and a vibrating pile hammer are connected together from bottom to top, wherein the vibrating pile hammer comprises a phase change device, a rotating shaft, a driving device and a base; the phase change device comprises a rotating disk, a phase change pipe, a phase change material and a phase change excitation device, and can avoid the problem that the vibration pile hammer does not have eccentric excitation force before reaching the working frequency during pile sinking, so that the vibration pile hammer generates resonance when the frequency of the excitation force passes through the resonance frequency of a hammer-pile-foundation system, and the eccentric excitation force is gradually generated when the frequency of a rotating shaft of the vibration pile hammer reaches the working frequency so that the pile is sunk into the soil. |
