Difference between manual digging pile and bored pile

The bearing capacity of hand-dug pile is slightly larger, because: punching cast-in-place pile is generally constructed with mud to protect the wall, and the lateral resistance of pile is not suitable for hand-dug pile. The bottom sediment of punched cast-in-place pile can't be cleaned, which easily exceeds the specification or design requirements, while the bottom cleaning of manual digging pile is cleaner, and the bearing capacity of pile bottom can be better exerted.

Manual digging piles are mostly suitable for gravel, rock and soil foundations with low water level, and workers can go down to work in the column pit, which is not very deep. Bored cast-in-place piles are mostly used in sandy soil, muddy soil and other foundations with high water level. These holes were formed by drilling machines, and they were cleaned and the walls were protected. Relative pile depth.

Pile foundation includes: hammer sinking cast-in-place pile, static pressure sinking cast-in-place pile, punching pile, manual digging pile, prefabricated pile, PHC pipe pile, root pile, anchor pile, etc. , because of its different construction methods, construction technology and quality control standards. For example, punching piles are punching holes, and the difference lies in the construction technology and quality implementation standards.
