Double-layer keel non-prestressed pile or column
The invention relates to a double-layer keel non-prestressed pile or column which comprises a pile body and a double-layer cage rib structure built in the pile body, wherein the pile body is in a hollow cylinder structure; the pile body close to the end part is externally sleeved with a steel pipe section; the pipe body and the steel pipe section are poured into a whole; and anchor pulling sections are arranged on the surface of the pile body on the two sides of the steel pipe section, and are in an indented or convex patterned structure. The double-layer keel non-prestressed pile or column has the advantages that with the adoption of the double-layer cage rib structure, the properties such as the shearing resistance and the bending resistance of the pipe body are improved; with the adoption of the steel pipe section, the pipe (column) body is embedded into a cast-in-place bearing platform, and can be rapidly and effectively welded with an embedded rib through the steel pipe section, then the pipe body is fixed; the steel pipe section and the embedded rib are made of metal, so that when the steel pipe section is welded with the embedded rib, the connection is more stable; and with the adoption of the anchor pulling sections, a friction force between the pile body and a contact surface around the pile body can be increased, thereby avoiding relative movement of the pile body well.
