Description

Technical Field

[0001] The utility model belongs to the technical field of pipe piles, and particularly relates to a high - bearing - capacity prestressed pile with a support structure. Background Art

[0002] A high - bearing - capacity prestressed pile is a type of pile foundation that improves the bearing capacity and flexural performance of the pile by applying prestress in the pile body. The application of prestress technology can effectively reduce the deformation of the pile under load and improve the service life and safety of the pile. In foundation engineering, although high - bearing - capacity prestressed piles have good vertical bearing capacity and flexural performance, in some cases, there may be a problem of lack of lateral support structure, which will have an adverse impact on the overall stability and bearing capacity of the pile foundation system. In soft or loose soil layers, due to the difficulty of obtaining sufficient lateral support for stress piles in related technologies, stress piles are prone to lateral displacement or inclination.
