Description

Technical Field

[0001] The present invention relates to the technical field of building construction, and in particular to a pile hole combination sleeve with a magnetic protective cover plate and an implementation method thereof. Background Art

[0002] At present, infrastructure construction is developing rapidly. Bored piles are a very common type of pile in the field of infrastructure construction. They refer to piles formed in the foundation soil at the construction site through mechanical drilling, steel pipe squeezing or manual excavation, and steel cages are placed inside and concrete is poured into the piles. According to different hole-forming methods, cast-in-place piles can be divided into several categories, such as sunken pipe cast-in-place piles, bored cast-in-place piles and excavated cast-in-place piles.

[0003] Due to existing technological limitations, there's a long gap between drilling and concrete pouring. Leaving the pile hole open during this period poses a safety risk, necessitating pile hole protection. Traditionally, pile hole protection involves welding steel mesh to cover the hole.

[0004] However, steel mesh has certain disadvantages: first, the mesh holes of the steel bars are relatively large. Although construction workers will not fall, it cannot prevent soil, small stones, and rainwater from entering the pile hole, which will have a certain impact on the pile foundation construction; second, the steel mesh is placed directly on the pile hole without effective fixing measures. Since the mesh is light and easy to shift, it loses its protective effect; finally, the steel mesh is easily buried by the surrounding soil during later construction, increasing the difficulty of recovery and turnover operations. Summary of the Invention

[0005] The object of the present invention is to provide a pile hole combination sleeve with a magnetic protective cover plate and an implementation method to solve the problems raised in the above background technology.
