Technical Field

[0001] The utility model relates to the technical field of composite piles, in particular to a composite pile foundation structure. Background Art

[0002] Composite piles refer to pile foundations that take into account the load of the soil between piles under the cap. Designing pile foundations according to composite pile foundations can greatly reduce the amount of piles used in a project. In composite pile foundations, the upper load is first transmitted to the pile body by the cap. When the pile body reaches its ultimate bearing capacity, a certain amount of settlement occurs, and the settlement is used to make the soil between piles bear part of the load.

[0003] The existing composite piles have solved the problems of compression resistance and pull-out resistance, but have not solved the problem of how to ensure the stability of the composite pile body when the soil is relatively loose. Therefore, the utility model proposes a composite pile foundation structure. Utility Model Content
