Product Name: Prestressed Concrete Interlocking Retaining Square Piles (Code: CFZ)

English name: Prestressed concrete chimeric type supporting square pile

Product Features

The CFZ retaining pile is a new-generation, high-performance, prefabricated concrete retaining pile with interlocking functionality, innovatively designed by integrating modern green industrial automation pile manufacturing technology. It features significant advantages such as high rigidity, high strength, high compactness, reliable earth-retaining performance, structural stability and durability, quick and easy construction, and cost-effectiveness.

Product structural shape

The product’s structural prototype is a hollow, thin-walled design featuring an “outer square, inner circle, with wings on both sides.”

H—section height; B—effective section width; D—inner diameter; t—wall thickness; L—pile length

Product Specifications and Model

CFZ retaining square piles are available in six standard sizes, categorized by cross-sectional width: 500 mm, 600 mm, 750 mm, 900 mm, 1050 mm, and 1200 mm. Based on differences in reinforcement ratio and flexural performance, they are further divided into various models—A, B, C, D, and E. Additionally, depending on the type of main reinforcement configuration, they can be classified as either fully prestressed CFZ retaining square piles or hybrid-reinforced CFZ retaining square piles.

Pile Splicing Technical Plan

CFZ Pile Splicing Process: The “end plate + shear-resistant stirrups + corner fillet welding” process is adopted. A schematic diagram of the proposed solution is shown below:
