The utility model relates to eccentric block excitation type shakeout technical field, concretely is an eccentric block excitation type shakeout device, including frame, shakeout platform, eccentric block excitation component, transmission component and damping support component, eccentric block excitation component produces centrifugal force through the rotation of symmetrical arrangement's sector eccentric block, and the excitation force is higher than traditional vibration motor, and can easily handle load sand box, solves the problem that high load shakeout is not thorough, adopts ordinary motor cooperation mechanical drive eccentric block, avoids vibration motor to bear vibration impact directly, and the service life of core component is prolonged, and through the replacement eccentric block of different quality or the adjustment counterweight hole counterweight, can flexibly adjust excitation force size, adapts the shakeout demand of different weight sand box, need not replace drive motor, and the helical spring of damping support component and guide column buffer vibration in coordination, reduce frame vibration transmission rate, improve the workshop working environment.

The application provides a gravel pile construction equipment, and relates to the technical field of ocean engineering. The gravel pile construction equipment comprises: a vibration pipe used for being inserted into a soil body to form a pile hole corresponding to a gravel pile; a first excitation source arranged at the top of the gravel pile and used for providing a downward force to the vibration pipe; and a plurality of second excitation sources arranged at the bottom of the vibration pipe and used for resonating at the bottom of the vibration pipe to provide a lateral vibration force to the vibration pipe. The embodiment of the application can improve the excitation force at the bottom of the vibration pipe by arranging the second excitation sources at the bottom of the vibration pipe, improve the compaction effect of deep soil, and diffuse vibration energy to the periphery of the vibration pipe to improve the compaction effect on the soil body around the pile.
