Secant or Tangent Piles. Secant or tangent piles are columns constructed adjacent (tangent) or overlapping (secant) each other to form structural walls that resist lateral pressures and groundwater inflow for bulkhead support, earth retention, groundwater control, or slope stability.

🔔 🔔 🔔 Secant pile walls are constructed by drilling and overlapping primary (unreinforced) and secondary (reinforced) piles to form a continuous retaining structure. They provide excellent groundwater control and structural stability in deep excavations, particularly for shafts, basements, and tunnel portals. The secondary piles are installed between the primary ones, cutting slightly into them to ensure full contact and minimise permeability. https://tunnel.engineering/courses/detail/tunnel-
