Hollow gyro pile and foundation treatment method thereof

Abstract

The invention discloses a hollow gyro pile and a foundation treatment method thereof, and relates to the technical field of foundation engineering. The hollow gyro pile (1) comprises a pile shoe (2),a pile foot (3), a pile body (4) and a pile head (5) from bottom to top; the pile shoe (2) is of an inverted conical structure; the pile foot (3) is of a cylindrical structure; the pile body (4) is ofan inverted-circular-truncated-cone-shaped structure, and the interior of the pile body is of a hollow structure; the pile head (5) is of a cylinder / circular plate type structure, the cylinder / circular plate type structure comprises four connecting edges adopting straight edges, and the connecting edges comprise female and male connectors (8); a semicircular / door-shaped connecting steel bar (7) is pre-embedded in the center of the pile head (5); and the hollow gyro pile (1) is manufactured by integrally pouring a polyethylene material. The durability is good, the dead weight is greatly reduced, the carrying operation of field constructors is facilitated, and the problem of low field construction efficiency of the traditional concrete gyro pile is solved; and meanwhile, a lot of raw materials are saved, and the environment is protected.

Description

technical field [0001] The invention belongs to the technical field of foundation engineering, and relates to a hollow gyro pile and a foundation treatment method thereof. Background technique [0002] Gyro pile is a new type of foundation form developed by Japan Gyro Industry Association. It is a shallow foundation treatment technology, which is similar to the traditional gravel replacement method. The gyro pile is to lay a gyro-shaped prefabricated concrete block on the surface of the foundation of the building and fill it with gravel, and squeeze the gravel to form an integral structural plate with a certain strength. The gyro pile composite foundation has a large diffusion angle, so that the stress can be evenly diffused into the foundation; at the same time, it can restrain the lower foundation, restrain the lateral deformation of the lower foundation, increase the bearing capacity and reduce settlement. This foundation treatment method is suitable for building non-hig...
