Secant Pile Earth Retention in Syracuse

摘要

To facilitate construction of new buildings and associated piping for the Woodland Reservoir Ultraviolet Light Treatment Facility in Syracuse, N.Y., Schnabel Foundation Co. designed and constructed an earth retention system utilizing overlapping steel reinforced concrete secant piles and tiebacks. Schnabel installed 600-plan-ft of secant pile wall with drilled depths of up to 63 ft within the existing reservoir embankment, which has been in service since 1894. Tiebacks were installed and tested to laterally support the secant pile wall for excavation depths of up to 41 ft. Close coordination between Schnabel and the project general contractor, C.O. Falter Construction Corp., was essential to maintaining the project schedule during secant pile and tieback installation.
