[0002] In the process of building construction, pile holes are an indispensable construction link. However, pile holes are usually deep and there is no fixed support around them, which poses a great safety hazard. Designing a new type of pile hole protection device to improve the protection effect and reduce safety risks has important practical significance.

[0003] The prior art discloses a reusable pile hole opening protection device (CN112878797A), which relates to the technical field of pile foundation engineering construction protection.
