Secant pile drum type foundation and construction method thereof

Abstract

The invention relates to the field of building foundations and foundations, in particular to a secant pile drum type foundation and a construction method thereof. The secant pile drum type foundation comprises reinforced concrete piles, plain concrete piles and a bearing platform, wherein parts of edges of adjacent reinforced concrete piles and plain concrete piles are embedded; the reinforced concrete piles and the plain concrete piles are distributed at intervals to form an annular pile foundation; and the bearing platform is positioned on the upper part of the annular pile foundation. Through the secant pile drum type foundation provided by the invention, load stressed on the foundation is dispersed to a horizontal confinement of a surrounding soil body to bear; the foundation has higher bending resistance capacity; the constraint force of the soil body is effectively utilized; great bending moment transferred from a high-rise structure can be born by the foundation; the foundation has a better supporting effect and protection effect; and compared with the conventional foundation, the foundation has the advantages of saving a certain amount of reinforcements and concrete.

Description

technical field [0001] The invention relates to the field of building foundations and foundations, in particular to an occlusal pile barrel foundation and a construction method thereof. Background technique [0002] At present, for large-scale equipment or equipment with dynamic loads, such as wind turbines, racks, and towers, the foundation forms used have disadvantages such as high cost, large deformation, and long construction period. [0003] my country is rich in wind energy. Due to the occurrence of the energy crisis and the use and development of green energy advocated in recent years, wind energy, as a clean, environmentally friendly and low-cost energy, has become an energy that advocates development. The wind power construction industry has also begun to develop continuously. , the construction of wind farms has a broader prospect. [0004] Although the cost of the wind turbine foundation accounts for a small proportion in the entire wind turbine cost, the safety o...

Problems solved by technology

[0007] The technical problem to be solved by the present invention is to provide a occlusal pile cylinder type foundation to overcome the existing existing foundations that require a large foundation area, consume a lot of concrete, require more steel bars, require a large amount of work, and have a long construction period. Problems such as high consumption
