Description

Technical Field

[0001] The utility model relates to the technical field of prefabricated piles, in particular to a prefabricated soil pile hoisting fixture. Background Art

[0002] Prefabricated soil piles are a common type of engineering field such as foundation treatment. Their production method is usually prefabricated in factories or construction sites through templates. Compared with cast-in-place piles, they have the advantages of low production cost, simple construction and short construction period. However, the prefabricated soil piles are heavy, so they need to be moved by lifting fixtures during transportation. In the prior art, before the prefabricated soil piles are pressed, the prefabricated soil piles need to be transferred to the pressing mechanism. In practice, the pile body is usually tied up with telescopic or iron chains, and then connected to the rope or iron chain by a crane, and the pile body is lifted by the crane. However, since the pile body is generally a cylinder or a cuboid, it is still feasible to tie it to the pile body with a rope or iron chain for cement piles, but for prefabricated soil piles, it is easy to cause deformation of the pile body, especially for piles that have not been cured and hardened. This will cause hidden dangers during the pile pressing process, and some even break, which brings great difficulties to on-site construction. In the prior art, there is also drilling holes on the pile body, which will also cause damage to the pile body. Summary of the invention
