[0002] Bored pile construction technology is a concrete technology with low construction cost, simple construction operation, no vibration, noise and soil squeezing effect. Bored pile construction technology has been widely used in the field of construction engineering. A large number of practical cases show that bored piles have high safety and strong stability, that is, the concrete slurry penetrates deep into the soil layer, which can make the soil layer and the bored pile body closely combined, so that the foundation is more solid and reliable. At the same time, the bored pile can effectively control the foundation settlement, thereby compacting the soil layer; bored piles have a good penetration, compaction and splitting effect on the soil layer, and the interaction between the three can make the soil layer more stable.

[0003] The traditional method of lowering the steel cage has obvious defects. When the crane lowers the steel cage to the bottom of the hole, the crane's sling cannot provide immediate and sufficient force on the side of the cage to help the steel cage stay in the center of the hole, resulting in the cage being deviated in many cases. Even if the workers on site make careful adjustments, in many cases the top of the cage is still in the center, but the bottom of the cage is still offset. Utility Model Content
