Secant pile walls | Keller UK
A secant pile wall consists of overlapping (secant) piles to form structural or cutoff walls and achieve the required water tightness. The design can incorporate steel bar or beams for reinforcement and anchors can provide additional lateral support, if needed. Common uses Enable and support excavations Support wing walls
Secant Pile Wall Construction rail system
The secant piles are reinforced with either steel rebar or with steel beams and are constructed by either drilling under mud or augering. Primary piles are installed first with secondary (male) piles constructed in between primary () piles once the latter gain sufficient strength. Pile overlap is typically in the order of 3 inches (8 cm).
What Is a Secant Pile Wall? | Eiffel Trading
A secant pile wall is a type of retaining wall used to ensure ground retention prior to excavation. Secant pile walls are created by constructing alternating primary and secondary piles ( and male piles) where the secondary piles partially cut into either side of the primary piles in order to form an uninterrupted, impermeable structure.

They can be installed in a broad range of soil conditions with unsurpassed speed, accuracy, minimal disturbance, and the ability to achieve tight tolerances at very close proximity to adjacent structures.
Secant Piles Shoring | Henry Foundation Drilling
The piles are reinforced with either steel rebar or steel beams and are constructed by drilling open hole, slurry drilling, continuous flight auger drilling, or using the temporary cased secant pile method. Primary piles are installed first with secondary piles constructed in between the primary piles once the latter gain sufficient strength.

Solved: Secant Pile Wall Autodesk Community
Hi All, I''m currently battling with a Secant Pile wall System whose height shouldnt go beyond the topography. Can anyone please help on how to go about this. The Piles should end at about 30cm below Topography surface. Usually i would create an inplace void but then when I do, I can''T seem to Cut the Pile System. I can upload the PileWall Family i created if that helps.
Secant piled walls | Keller Australia
Secant pile walls are installed as cast in situ bored or CFA piles, and often installed through a temporary concrete guide. ... The guide ensures that piles are accurately located to achieve an interlock (or ''secant'') cut into the adjacent pile.

What is secant piling, and how does it work?
What is the Secant Piling Method? Pile walls can be either closelyspaced contiguous piles walls or secant pile walls. Secant pile walls are formed by constructing reinforced concrete piles that interlock, and are often used as a costeffective solution when shortterm water retention is required. Secant piles are reinforced with either steel ...
Secant Pile Shoring Developments in Design and Construction
the versatility offered by secant piling allows effective construction through highly variable ground profiles ranging from saturated cohesionless soils to hard rock, including advance through cobbles and boulders and even manmade obstructions. For secant piling, installation tolerance is critical to project success and directly related to cost.
Secant Pile Walls for Earth Retention Nicholson Construction
Secant pile walls can be successfully installed in virtually any ground conditions, including grounds that are typically difficult to work with. Secant pile walls are ideal for urban construction projects, as they can easily be installed in tight spaces and are more flexible in shape than diaphragm walls.
what is a secant anchored pile wall? Construction Leaders
This secant pile wall is a permanent retaining wall system for ground retention prior to excavation. The primary bored piles were constructed of plain concrete, while the secondary bored piles were constructed of reinforced concrete. The reinforced piles are then installed and the reinforcement can be either cage, Ibeams, or Hbeams.
