Description

Technical Field

[0001] The utility model relates to the technical field of building pipe pile hole cleaning equipment, in particular to a prefabricated pipe pile hole cleaning device. Background Art

[0002] Prefabricated pipe piles are commonly used basic structural materials in modern construction. Their quality and construction efficiency have an important impact on the safety and economy of the overall project. During the construction of pipe piles, soil accumulation in the pile core is a common problem, which will affect the bearing capacity and stability of the pipe piles. Therefore, an effective hole cleaning device is needed to clean the soil accumulated in the pile core.

[0003] At present, manual hole cleaning is generally used for the core cleaning of prefabricated pipe piles in foundations. Manual cleaning usually requires workers to use hand-held tools such as semicircular shovels, Luoyang shovels, scrapers, hooks, etc. for long-term and high-intensity work. This not only consumes a lot of physical strength of workers, but also may reduce work efficiency. In the case of rapid cleaning of a large amount of core soil in pipe piles, manual cleaning may not meet the construction period requirements. Manual cleaning is limited by the skills and experience of workers, which may lead to uneven cleaning effects and incomplete cleaning. In particular, for some hard-to-reach corners and gaps, manual cleaning may not be able to completely remove the core soil.

[0004] For this purpose, a prefabricated pipe pile hole cleaning device is invented to solve the problems of high labor intensity and low cleaning efficiency when manually cleaning the holes of prefabricated pipe piles. Utility Model Content

There is a sliding frame 4 that can slide up and down, and a rotatable collecting shell 5 is rotatably connected to the middle part of the sliding frame 4. The collecting shell 5 is set to a cylindrical shape, which is used to collect core soil. A fixed cylinder 6 is fixedly connected to the collecting shell 5. When the collecting shell 5 rotates, the fixed cylinder 6 inside it is driven to rotate. A rotatable rotating auger 7 is rotatably connected to the fixed cylinder 6.
