What is a Secant Pile Wall? - Schnabel
Nov 10, 2023 · Secant pile walls also referred to as secant piles or secant walls, are a construction technique used to provide rigid lateral support to excavations and underground structures. They are constructed by drilling a series of overlapping concrete piles or shafts.
Secant pile walls - Keller Group plc
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.
Secant Pile Walls: Construction Process, Types, and Advantages
Jul 2, 2024 · Secant pile walls provide a reliable solution for constructing foundations and retaining walls in these conditions. They are used to create dry docks, marinas, and other waterfront structures, ensuring that the surrounding water does not compromise the integrity of the construction.
Secant Pile Wall Construction - rail system
Secant pile walls are formed by constructing intersecting reinforced concrete piles. The secant piles are reinforced with either steel rebar or with steel beams and are constructed by either drilling under mud or augering.
Secant & Tangent Pile Walls in Deep Excavations
DeepEX can Design any Secant or Tangent Pile Wall Model in Minutes! Review Software Capabilities. Selecting the appropriate secant pile wall depends mostly on local practice, material, and installation costs. In the US, secant piles are commonly reinforced with steel I or W beams.
A secant pile wall is constructed by installing concrete or cement/bentonite grout primary vertical piles (with or without steel reinforcement) at prescribed intervals.
Everything You Need to Know About Secant Pile Walls
Secant pile walls are bored pile retaining walls developed by connecting primary and secondary piles, creating a continuous wall. Unlike diaphragm retaining walls, they offer flexibility in design and shape, providing a stronger advantage over sheet-piled walls.
Secant pile walls are formed by constructing a series of overlapping “primary” and “secondary” concrete-filled drill holes. The primary piles are constructed first, followed by secondary piles, which are cut into the previously placed primary pile concrete.
Secant Walls | Secant Wall Construction | Complete Guide
Oct 16, 2021 · Secant Walls or Secant Pile Walls are constructed of intersecting buttressed concrete piles for strengthened support. Steel rebars or steel beams bolster these secant piles up, and then they are augured using machinery or hand augers.
Secant or tangent (contiguous) piles | Keller North America
Secant or tangent piles are columns constructed adjacent (tangent) or overlapping (secant) to form structural or cutoff walls. From soil mixing to drilled shafts, we draw on our complete suite of techniques to optimize the design and construction of these walls.
