Abstract: Compared with other hole forming processes, manual hole digging pile does not need large-scale mechanical equipment, and has many advantages, such as convenient construction, simultaneous excavation of multiple piles, and little impact on the surrounding area. However, this process is carried out manually in the well, so it is dangerous and difficult to control safety. In view of this, combined with examples, this paper comprehensively discusses the key technology of manual hole digging pile construction for reference.
