Description

Technical Field

[0001] The utility model belongs to the technical field of friction piles, and in particular relates to a friction-type prestressed pile with a positioning structure. Background Art

[0002] Friction-type prestressed piles are a type of pile foundation commonly used in building foundation engineering. Prestressed piles enhance the bearing capacity and anti-deformation ability of the piles by applying prestress (usually by tensioning steel bars or steel cables). Friction-type prestressed piles mainly rely on the friction between the pile body and the surrounding soil to transfer loads. The larger the surface area of the pile, the greater the friction force. Therefore, the treatment of the pile surface (such as roughening) can enhance the friction force. Due to the lack of a positioning structure in the friction-type prestressed piles in the related technology, the position of the pile foundation is prone to deviation during driving, making it difficult to ensure the accurate positioning of each pile foundation, and may cause uneven distribution of the pile foundation, affecting the stability and bearing capacity of the overall structure.
