Title: Flanged deep corrugated vertical shaft liners

Title execution:

Archives of Institute of Civil Engineering

Abstract:

Vertical shafts are used for ventilation, access for equipment/personnel, or storm-water transmission to underground cavities. Larger diameter vertical shafts are traditionally lined using either concrete or flat steel forms. This paper introduces flanged deep corrugated plate (FDCP) as an economical vertical shaft liner. For safety and accessibility reasons, shaft liners typically require installation be conducted from only one side of the liner. Shallow corrugated steel liner plates, which enables one side assembly, has been used for decades. However, shallow corrugated liner plate’s strength has limited their use to smaller (less than 6 m) diameters. FDCP, commonly referred to as The Edge, was first introduced to the marketplace in 2012 and is five times stronger and nine times stiffer than traditional steel liner plate. FDCP is available in two-flange and four-flange configurations and is best suited for applications: 1. required to resist ground/hydrostatic pressures or ground movements greater than the capacity of shallow corrugated liner plate; 2. needing to resist unbalanced loads; 3. where greater flowable fill pour heights are desired; 4. with diameters > 6 m. FDCP is designed to the same structural limit states as traditional overlap plates with the additional consideration of shear load at bolted connections. AASHTO LRFD Section 12.13 may be used as a guideline when determining loads and structural limit states for vertical shaft liners. FDCP is well suited for vertical shaft liners. Vertical shafts with diameters > 6 m and depths < 40 m are generally more economical and faster to construct when lined with FDCP. Product and construction innovations are required to increase advancement rate and shaft depth for which FDCP compares favourably to traditional concrete liner.
