Low-strain hammering device for large-diameter super-long pile and application method of low-strain hammering device
The invention belongs to the technical field of foundation low-strain detection, and discloses a low-strain hammering device for a large-diameter super-long pile and an application method thereof.The device comprises a supporting frame, a pulley block structure, an automatic unhooking device, a heavy hammer and a hammer pad, the height of the supporting frame is adjustable, and the upper end of the pulley block structure is fixed to the center of the top of the supporting frame; the central axis of the pulley block structure is vertically downward and is positioned on the same straight line with a to-be-measured point of the foundation pile; the lower end of the pulley block structure is connected with the upper end of the automatic unhooking device, a heavy hammer is hung at the lower end of the automatic unhooking device, the pulley block structure can enable the automatic unhooking device to drive the heavy hammer to rise to a preset height, and after the automatic unhooking device is opened, the heavy hammer can align to a to-be-measured point to do free falling motion; the hammer pad is arranged on the surface of the foundation pile below the heavy hammer, the heavy hammer freely falls onto the hammer pad to generate excitation waves, and the hammer pad can mechanically filter the excitation waves. The operation of the large-diameter ultra-long pile low-strain excitation device can be completed by one person.
本发明属于地基低应变检测技术领域，公开一种大直径超长桩的低应变锤击装置及其应用方法，装置包括：包括支撑架、滑轮组结构、自动脱钩装置、重锤和锤垫，其中：支撑架高度可调节，滑轮组结构的上端固定在支撑架的顶部中心，且滑轮组结构的中心轴线竖直向下并与基桩的待测点位于同一直线；滑轮组结构的下端与自动脱钩装置上端连接，自动脱钩装置下端悬挂有重锤，滑轮组结构能使自动脱钩装置带动重锤上升到预设高度，自动脱钩装置打开后能使重锤对准待测点做自由落体运动；锤垫设置在重锤下方的基桩表面上，重锤自由落体到锤垫上产生激振波，锤垫能对激振波进行机械滤波。本发明通过单人即可完成大直径超长桩低应变激振装置的操作。
