A common heavy hammer type rammed expanded pile machine is composed of a chassis connected with a bracket, a heavy hammer is installed on the bracket, a pile cylinder is placed outside the heavy hammer, and the pile cylinder and the heavy hammer are respectively connected with two sets of hoists installed on the chassis by steel wires passing around the cross beam on the bracket. During piling, a specific device is used to hammer and form a hole, and the casing is counter-pressed until the predetermined depth. Dry sand, soil, etc. are filled in the casing. Then, the hoist is used to lift the heavy hammer to a certain height, and then the heavy hammer freely falls to compact the filled sand, soil, etc.
[0003] The existing heavy hammer is connected to the equipment through a hook. Since the existing hook is not in a closed loop state, when there is shaking, the heavy hammer is likely to fall off the hook, resulting in poor safety. Therefore, there are potential safety hazards during construction on the construction site, which may induce losses of personnel and resources. Therefore, we propose a heavy hammer for rammed expanded pile construction and pile forming. Summary of the Utility Model
