A secant pile wall is formed by overlapping piles to create structural or cutoff walls, ensuring water tightness. Steel bars or beams can reinforce the design, and anchors may offer extra lateral support when necessary.

​

Common uses

• Slope stabilization

• Enable and support excavations

• Support bulkheads

• Water cut off

​

Process

Secant pile walls feature both reinforced and non-reinforced piles. Non-reinforced piles, typically made of cement or bentonite, are initially installed, followed by reinforced piles using cages, I-beams, or H-beams. Walls supported by anchors or strutting systems employ a waler beam to distribute loads, preventing puncturing of the piles and serving as a contingency for potential load failure. This waler beam can be a reinforced concrete beam casted against the pile wall or steel profiles attached to the piles and support systems.

Advantages

• Suitable for various soil conditions, even amidst cobbles and boulders.

• Minimal external deformation and settlement.

• Capable of bearing substantial loads from adjacent structures.

• Reduced vibration during the construction process.
